Introduction: Why Air Tag Battery Life Actually Matters
If you've ever opened your Air Tag case only to find a dead CR2032 battery staring back at you, you know the frustration. That tiny coin cell lasts about a year under normal use, which means you're either replacing batteries constantly or, let's be honest, you forget and suddenly your Air Tag becomes a useless plastic disc in your backpack.
The problem isn't really technical. It's practical. Apple designed Air Tags with consumer simplicity in mind, not durability. The CR2032 was the obvious choice: compact, affordable, widely available. But it comes with a hidden cost: endless battery replacements. For people tracking vehicles, equipment, or anything that needs to work reliably for years without attention, this becomes a real headache.
That's where alternative solutions come in. And one of the most interesting approaches is what Elevation Labs built with their Time Capsule case. Instead of fighting Apple's battery choice, they worked around it. The result is a case that uses two AA batteries to extend Air Tag runtime from months to a decade. At
In this guide, we'll dig into everything about extended battery solutions for Air Tags. We'll look at how the Time Capsule works, compare it to other options, examine the real-world scenarios where it makes sense, and help you decide if this is the accessory you actually need. Because the best solution depends entirely on your use case.
TL; DR
- Extended Runtime: Elevation Labs Time Capsule offers 10-year extended battery life using two AA batteries instead of one CR2032
- 14x Longer Life: The battery case provides up to 14 times the lifespan of standard Air Tags
- Waterproof Design: IP69 waterproof rating and fiber-reinforced construction provide durability
- Affordable at Sale Price: 23) makes this a reasonable accessory for specific use cases
- Best For: Vehicles, luggage, work equipment, and other items that sit for extended periods


The Elevation Labs TimeCapsule extends battery life to 10 years, significantly longer than the standard AirTag's 1-year lifespan.
Understanding Air Tag Battery Fundamentals
Before we can appreciate why the Time Capsule exists, we need to understand what Apple's original design actually does. An Air Tag runs on a single CR2032 battery, which is a 3-volt lithium coin cell. These batteries measure just 20mm in diameter and 3.2mm thick, making them perfect for slim devices. The CR2032 stores about 220 milliampere-hours of energy, which sounds like a lot until you realize how quickly Bluetooth transmission drains that capacity.
Here's the math: an Air Tag actively broadcasts its location multiple times per second when in use. Even when idle, it maintains a low-power Bluetooth connection. The CR2032 lasts roughly 12 months under typical conditions, according to Apple. But "typical" is doing some heavy lifting here. If you're in an area with dense Bluetooth interference or your Air Tag is constantly updating its position, battery life can drop to 8-10 months. If it sits inactive, you might stretch to 16 months.
What's interesting is that the Air Tag's power consumption isn't actually that high. The real limitation is the CR2032's total capacity. A coin battery simply can't store much energy, and Bluetooth, despite being a low-power protocol, still demands constant juice. This is why smaller form factors always come with battery tradeoffs.
Apple clearly made the right choice for their target market. Most people carrying Air Tags don't mind swapping a battery once a year. It's a minor inconvenience, not a deal-breaker. But for specific use cases, annual battery replacement becomes absurd. If you're tracking a work vehicle that doesn't move during winter, or a piece of luggage in storage, or equipment in a warehouse, changing the battery four times during the device's lifespan is wasteful and easy to forget.


Estimated data shows that keys and wallet tracking consumes the most power due to frequent movement, while vehicle tracking consumes the least over five years.
The Problem with Standard Air Tag Batteries
Let's be blunt: the CR2032 battery creates ongoing costs and friction. When you buy an Air Tag, you're not just paying the upfront price. You're committing to a subscription of battery replacements for as long as you own it. A CR2032 costs between
But there's something more subtle happening. People forget. You place an Air Tag in your vehicle. Months pass. The battery dies. You don't realize it. Your Air Tag becomes useless exactly when you'd need it most, like if your car actually went missing. Or you store equipment for a season, the battery dies, and you don't think to replace it before using the item again.
This forgetting problem is why extended battery solutions matter. A case that works for ten years doesn't require you to remember anything. Set it and forget it. Your Air Tag will still be broadcasting location data when you need it, without intervention.
The other issue is form factor. The Time Capsule isn't as slim as the original Air Tag enclosure. It measures 4.45 inches by 1.57 inches, making it more rectangular than the original round design. That extra bulk matters if you're attaching an Air Tag to car keys or a slim wallet. Some people won't accept that tradeoff. Others—particularly those using Air Tags in luggage, vehicles, or work equipment—won't care about an extra quarter-inch.

Elevation Labs Time Capsule: How It Works
The Time Capsule is elegantly simple in concept. Instead of using one CR2032, it uses two standard AA batteries in a custom case. This immediately gives you more total energy storage: two AA batteries provide roughly 2,800 to 3,000 milliampere-hours combined, compared to the 220m Ah in a CR2032. That's roughly 13x more energy, before accounting for voltage regulation and efficiency losses.
But the math is slightly trickier than "more capacity equals longer life." The Time Capsule doesn't just give the Air Tag twice as much power. It has to regulate voltage appropriately. AA batteries start at 1.5 volts each when fresh. Two in series gives 3 volts, which is perfect for the Air Tag's electronics. As the batteries drain, voltage drops. The case includes circuitry to maintain proper voltage output as the cells deplete, ensuring consistent Air Tag operation across the full battery lifespan.
Elvation Labs claims 10-year battery life based on Energizer Ultimate Lithium AA batteries. These aren't standard alkaline batteries. Lithium AA batteries have higher energy density and better performance in low-drain applications compared to alkaline alternatives. They also handle temperature variations better, which matters if your tracked item sits in a hot vehicle during summer.
The physical design is worth noting. The case is fiber-reinforced, which adds structural strength without significant weight or bulk. The lid screws down at four corners, creating a secure seal that's difficult to open accidentally but still accessible for battery replacement. This design prevents the batteries from sitting loose, which could cause voltage drops or poor contact.
Elvation Labs rates the case as IP69 waterproof. IP69 is actually above IP68 in terms of water resistance. It means the case handles high-pressure water jets and brief immersion, though probably not extended underwater use. For a vehicle Air Tag or luggage tracker, this is more waterproofing than you'll ever need. Rain, car washes, and spilled drinks won't harm the electronics inside.


The TimeCapsule using two AA batteries is estimated to last 10 years, significantly longer than the 1-year lifespan of an AirTag using a CR2032 battery. Estimated data based on typical usage patterns and battery capacities.
Battery Life Calculation: What the Numbers Really Mean
When Elevation Labs claims a 10-year lifespan or "14 times longer" than standard Air Tags, how did they arrive at that number? Let's reverse-engineer the math to understand what you're actually getting.
An Air Tag running on a standard CR2032 lasts approximately 12 months. The Time Capsule using two AA batteries lasts 10 years. That's 10 years divided by 1 year, or a 10x multiplier. So where does the "14x" claim come from?
The 14x likely refers to a comparison between battery capacity (not calendar time). Here's the logic: two AA batteries contain roughly 3,000m Ah combined. A CR2032 contains roughly 220m Ah. That's approximately 13.6x more energy, which rounds to 14x. However, actual battery life depends on more than just capacity. It depends on discharge rate, power consumption patterns, and voltage regulation efficiency.
Let's estimate real-world numbers using basic battery physics:
Assuming an Air Tag draws roughly 20 microamperes in standby and 100 milliamperes during active transmissions (which happen briefly, several times per second):
- CR2032 with 220m Ah capacity: roughly 12 months
- Two AA batteries with 3,000m Ah capacity: roughly 10 years
This assumes voltage regulation losses of roughly 10-15%, which is reasonable for a quality converter. The actual lifespan depends heavily on how often your Air Tag broadcasts. An Air Tag in a vehicle that moves daily will drain faster than one in stationary luggage.
The practical takeaway: expect 8-10 years from the Time Capsule using quality lithium batteries, with actual performance varying based on your specific use case. An Air Tag in a constantly-moving vehicle might see slightly reduced lifespan (7-8 years) compared to one in stationary luggage (10-12 years).

Comparing Extended Battery Options
The Time Capsule isn't the only way to extend Air Tag battery life, though it's probably the most popular. Let's look at the landscape of alternatives.
Replacement with Standard Alkaline Batteries
The cheapest option is simply buying quality replacement batteries. A pack of four CR2032 batteries costs
Third-Party Solar Cases
Several manufacturers sell solar-charging cases for Air Tags. These use tiny solar panels to trickle-charge the internal battery. In theory, an Air Tag with a solar case never needs battery replacement. In practice, solar cells only work when exposed to light, and a small solar panel on an Air Tag case generates minimal current. Unless your Air Tag sits in a sunny window eight hours per day, you're looking at supplemental solar charging, not replacement charging.
The reviews on solar cases are mixed. Some users report modest lifespan extensions (18-24 months instead of 12 months). Others see no significant improvement. The problem is that solar generation is unreliable and hard to calculate. You can't know with certainty that your Air Tag will actually stay charged.
DIY Battery Case Modifications
Tech enthusiasts have created custom cases holding larger batteries or even rechargeable cells. These work, but they require sourcing parts, soldering, and testing. A DIY solution costs $15-30 in parts and an hour of technical work. Unless you're comfortable with electronics, it's not worth the hassle.
Multiple Air Tags with Staggered Replacement
Some users simply buy multiple Air Tags for a single item and rotate through them, replacing batteries on a schedule. This is actually reasonable if you're already comfortable buying multiple Air Tags. A four-pack costs roughly the same as one Time Capsule, and you get redundant tracking (useful if one device fails).
However, this adds complexity. You're managing multiple device IDs, multiple battery replacements, and slightly more bulk. It's overkill for most users.


Over 5 years, the TimeCapsule at the sale price offers significant savings compared to standard battery replacements. Estimated data based on typical usage.
The Time Capsule at $16: Value Analysis
With the 30% discount bringing the Time Capsule down from
- Extended battery life ($0.16 per year, if amortized over 10 years)
- Waterproof protection ($3-5 comparable to other protective cases)
- Design and engineering ($5-8 in manufacturing and R&D)
- Convenience (priceless, but let's call it $2-3)
At
However, economics only matter if you'll actually use the full 10-year lifespan. If you replace your Air Tag in three years (as you might if you upgrade your tracking setup or replace a lost item), you're wasting the potential battery life. The value proposition depends entirely on your expected usage timeline.
The waterproofing adds genuine value too. Standard Air Tag cases offer varying levels of protection, but few match IP69. For tracking vehicles, outdoor equipment, or luggage that gets tossed around, waterproofing prevents corrosion and damage from environmental exposure.

Best Use Cases for Extended Battery Cases
The Time Capsule makes sense for specific scenarios. It's not a universal solution, and that's okay. Understanding when to use it is more important than understanding how it works.
Vehicle Tracking
The most obvious use case is tracking a vehicle. Once you affix an Air Tag inside your car (hidden under the seat or in the glove box), it just sits there. You check it occasionally if the car ever goes missing, but otherwise, you forget about it. A 10-year battery life means your vehicle has continuous Find My coverage for the duration of your ownership, without any maintenance.
Compare this to standard batteries: you'd need to access your vehicle's Air Tag 10 times over a decade to swap batteries. The Time Capsule's larger form factor doesn't matter since it's hidden from view.
Equipment and Asset Tracking
Businesses tracking expensive equipment, tools, or inventory benefit enormously from 10-year battery life. A work Air Tag attached to a welding machine, generator, or server doesn't move frequently. Over a year, it probably consumes far less power than an Air Tag on someone's keys. The extended battery becomes almost a permanent solution.
For fleet management or warehouse operations, the Time Capsule's value multiplies. You're installing hundreds of devices and tracking them for years. Reducing battery maintenance from annual swaps to decade-long intervals saves labor costs, prevents forgotten replacements, and ensures continuous coverage.
Travel Luggage and Long-Term Storage
If you travel occasionally and keep luggage in storage between trips, an Air Tag with extended battery makes sense. Your luggage might sit untouched for six months, then get packed for a trip. A standard Air Tag's battery might die during storage, leaving you unprotected on that trip. The Time Capsule ensures your luggage is trackable whenever you need it.
The same applies to seasonal equipment: winter sports gear, holiday decorations, camping equipment. These items often sit for 6-9 months between uses. Extended battery life ensures your tracking is ready whenever you retrieve the equipment.
Situations Where the Time Capsule Doesn't Make Sense
Conversely, the Time Capsule is overkill for everyday items. If you're tracking your keys or your backpack with an Air Tag you check every single day, you'll probably replace that Air Tag or the device it's tracking before the battery dies. A standard battery case is perfectly adequate.
The same applies if you already have a strong tracking system through your phone or vehicle. The Air Tag is a backup, not primary infrastructure. For backup systems, the lower cost and simpler design of standard cases might be preferable.


The TimeCapsule offers a balanced solution with extended battery life and competitive pricing, making it a strong contender among AirTag cases. Estimated data for protection ratings.
Technical Deep Dive: Fiber-Reinforced Construction and IP69 Rating
The Time Capsule's construction deserves attention because it reflects the engineering decisions that justify its price.
Fiber-reinforced cases are typically made from nylon or polycarbonate with embedded fiberglass strands. This composite material is stronger than pure plastic but lighter than metal. It resists impact damage better than basic plastic while remaining flexible enough to absorb shock without shattering. For a device that might be thrown into luggage, vehicles, or work environments, this is legitimate value.
The IP69 waterproof rating means the case survives:
- Sustained submersion in water up to 1 meter depth
- High-pressure water jets from any direction
- Temperature extremes from 0°C to 80°C
- Salt spray and corrosive environments (for IP69K variant)
IP69 is overkill for most Air Tag use cases, but it's also reassuring. If your Air Tag ends up in a car wash, rainstorm, or gets splashed with salt water near the coast, the case will protect the electronics inside. This is especially valuable for vehicle-based Air Tags, which encounter more environmental hazards than typical.
The screw-down design (four corner screws) is worth noting because it's more secure than click-snap closures common on cheaper Air Tag cases. Screws won't pop open if the case gets jostled or compressed. The tradeoff is that battery replacement requires a screwdriver, adding friction to an already low-frequency task (batteries change maybe once per decade, remember).

Installation and Battery Replacement Walkthrough
Setting up the Time Capsule is straightforward, though it differs slightly from a standard Air Tag case.
Initial Setup
- Acquire two AA lithium batteries (Energizer Ultimate Lithium or equivalent)
- Open the case by removing four corner screws with a small Phillips head screwdriver
- Insert batteries into the battery compartment, observing correct polarity (positive and negative ends oriented properly)
- Place your Air Tag into the case cavity
- Close and secure the lid by replacing all four screws
- Wait 30 seconds for the Air Tag to boot and register with Find My
- Test by opening the Find My app and confirming the Air Tag appears and reports signal
Periodic Battery Replacement
Battery replacement happens roughly once per decade (or sooner, depending on use). The process mirrors initial setup:
- Remove the four corner screws
- Lift off the lid and carefully extract the dead batteries
- Insert fresh AA lithium batteries, again observing polarity
- Replace the Air Tag (optional; you can keep the same device)
- Reseal the case with the four screws
- Verify in Find My that the device still reports correctly
The entire process takes about three minutes. The screwdriver requirement is minor friction, but it ensures the case stays securely closed during normal use.


Size and bulk are perceived as the most significant drawbacks of the TimeCapsule, followed by upfront cost. Estimated data based on typical user concerns.
Comparison with Competitors and Alternatives
Elevation Labs isn't the only company selling extended battery cases for Air Tags. Understanding the competitive landscape helps justify whether the Time Capsule is the best choice.
Spigen Air Tag Case
Spigen offers a basic Air Tag case that's purely protective, no battery extension. It's inexpensive ($5-8) and focuses on drop protection and design variety. For someone who doesn't mind replacing batteries annually, Spigen is the economical choice. You get protection without the bulk of an extended battery case.
Tech 21 Air Tag Case
Tech 21's Air Tag case emphasizes shock absorption and durability, with military-grade protection. It costs $15-18 and offers substantial drop protection but still uses the standard CR2032 battery. If your concern is physical durability rather than battery life, Tech 21 might be the better fit.
Nomad Air Tag Leather Case
For aesthetic-focused users, Nomad offers premium leather cases that feel luxurious and age beautifully. These cost $30-50 and are designed for style as much as protection. No battery extension. These appeal to people who attach Air Tags to items where appearance matters (designer bags, premium wallets).
DIY Alternatives
Tech enthusiasts have shared designs for custom Air Tag cases using larger batteries or rechargeable cells. These offer maximum flexibility and potentially lower cost ($10-20 in parts), but require sourcing materials, assembly, and testing. Not practical for non-technical users.
Why the Time Capsule Wins for Extended Battery
Among purpose-built extended battery solutions, the Time Capsule stands out because it balances capacity, reliability, and cost. Two AA batteries provide a proven balance between power storage and case size. Elevation Labs is an established accessory maker with a reputation for quality. The $16 sale price is aggressive compared to competitors.
The main alternative would be buying a solar charging case, but as discussed earlier, solar performance is unreliable. The Time Capsule's predictable 10-year lifespan is more valuable than the theoretical unlimited life of a solar solution that might not actually charge consistently.

Real-World Scenarios and Performance Expectations
Let's ground this in actual usage patterns.
Scenario 1: Vehicle Tracking for Five Years
You buy a used car and want Find My coverage in case of theft. You install an Elevation Labs Time Capsule Air Tag under the driver's seat. The car sits parked 20 hours per day. The Air Tag broadcasts its location roughly 4-5 times per second, but each broadcast is short. Total power consumption is minimal, probably 10-15 microamperes on average.
Over five years, the Air Tag uses roughly 450-600 milliampere-hours from the 3,000m Ah batteries. You could easily see 20-25 years of lifespan under these conditions. By the time the battery dies, you've probably sold the car and replaced the Air Tag anyway. The Time Capsule was perfect for this use case.
Scenario 2: Keys and Wallet Tracking
You attach an Air Tag to your keys and put it in a Time Capsule case. Your keys are with you most of the day, moving around, occasionally out of range and reconnecting. The Air Tag broadcasts more frequently because it's more active. It might consume 30-40 microamperes on average.
Over five years, the Air Tag uses roughly 1,350-1,800 milliampere-hours. You'd see roughly 8-10 years of lifespan. But here's the thing: you probably don't keep the same keys for 8-10 years. You lose keys, replace them, upgrade your wallet. The extended battery life is partially wasted because the physical item it's tracking has a shorter lifespan than the battery itself.
For keys and wallets, a standard battery case is more appropriate. The total cost of ownership (battery replacement + case) is probably lower than the upfront cost of a Time Capsule.
Scenario 3: Backup Travel Luggage
You have a large suitcase you only use 2-3 times per year for long trips. The Air Tag spends 85% of its time in a closet, consuming minimal power. When you travel, it's actively tracking but only for 1-2 weeks at a time.
Over five years, the Air Tag uses maybe 500-700 milliampere-hours total. The battery could last 20+ years. But more realistically, you'll eventually wear out or replace the suitcase before the battery dies. The Time Capsule's extended battery is mostly unnecessary insurance.
However, there's value in peace of mind. Knowing your luggage is protected without worrying about battery death justifies the $16 purchase for someone who travels regularly.

Environmental and Sustainability Considerations
Extended battery life has environmental implications that often go unnoticed.
A standard CR2032 battery discarded every year generates 14 batteries over 14 years. Each battery requires mining, processing, manufacturing, and transport. The environmental cost of those 14 batteries across raw materials, energy, and transport is substantial. From a lifecycle perspective, replacing a battery annually creates more environmental impact than using one extended-life solution.
Two AA batteries used across 10 years means only one battery replacement. That's a 93% reduction in battery count. The fiber-reinforced case might last longer than standard plastic cases, further reducing replacement frequency.
Elvation Labs could improve this by designing the case for easy battery access without a screwdriver, or offering a rechargeable battery option. But compared to the battery churn of standard Air Tag cases, the Time Capsule is already more sustainable.
For businesses using hundreds of Air Tags, the environmental case for extended battery is compelling. A fleet tracking system with 500 Air Tags that need annual replacement cycles through 5,000 batteries per decade. Switching to extended battery cases reduces that to 500 total batteries. That's not a minor difference.

Pricing Tiers and When to Buy
At the standard
Here's a pricing strategy: if you have more than one item you want to track for 5+ years, buying the Time Capsule at the sale price is almost certainly cheaper than replacing batteries annually on standard cases. The break-even is roughly 3-4 years of standard battery replacements, or about $20-30 in batteries.
The sale price of $16 is notably aggressive. Elevation Labs might be clearing inventory, running a limited promotion, or trying to build market share. These sales often revert to full price without warning. If the sale price is available and you think you might use an extended battery case within the next six months, it's a reasonable time to buy.
If you only need one or two Air Tags for casual tracking, the standard battery case is probably adequate. The Time Capsule's value scales with the number of devices you're managing and the duration you plan to keep them.

Potential Drawbacks and Honest Assessment
No product is perfect, and the Time Capsule has legitimate drawbacks worth considering.
Size and Bulk
The 4.45 x 1.57 inch form factor is noticeably larger than the original Air Tag. If you're attaching this to car keys or a slim wallet, it will be bulkier. Some people won't accept that tradeoff. The original Air Tag is designed to be unobtrusive; the Time Capsule is more obvious.
Screwdriver Requirement
Battery replacement requires a Phillips head screwdriver. For a process that happens once per decade, this is minor friction. But it's friction nonetheless. Someone who loses their screwdriver or is uncomfortable with basic mechanical tasks might find this annoying.
Upfront Cost
At
Voltage Regulation Efficiency
While the case includes voltage regulation, it's not perfect. Some energy is lost in the conversion process. In practice, this means the actual battery lifespan might be slightly less than the theoretical 10 years. Elevation Labs bases its claims on Energizer Ultimate Lithium batteries specifically. Generic AA batteries might perform 10-20% worse.
No Charging Capability
Unlike some third-party Air Tag cases, the Time Capsule doesn't include wireless charging or USB-C charging. You can't top up the batteries wirelessly; you have to physically open the case and replace them. For a 10-year battery life, this is acceptable. But it means the case doesn't offer the convenience of rechargeable solutions.

Installation Tips and Best Practices
Even with a straightforward design, a few practices will maximize the Time Capsule's performance.
Use Lithium Batteries, Not Alkaline
Elvation Labs specifically recommends Energizer Ultimate Lithium AA batteries. These cost slightly more ($6-10 per four-pack) than standard alkaline batteries but offer superior performance in low-drain devices. Lithium batteries maintain voltage more consistently as they discharge, which is crucial for electronics. Alkaline batteries might work, but you'll see reduced lifespan and potentially spotty performance as voltage drops more dramatically.
Check Battery Orientation
Battery polarity matters. Insert the positive end (marked with a +) toward the positive terminal in the case. Most cases have a small diagram showing correct orientation. Getting this wrong can damage the voltage regulator or prevent proper operation.
Don't Mix Battery Brands
If you need to replace one battery before both are fully depleted, use the same brand as the other battery. Mixing different brands can cause voltage irregularities if they discharge at different rates.
Test After Replacement
When you finally replace the batteries (probably years from now), test the Air Tag in Find My immediately to confirm proper operation. A faulty battery connection or polarity error might not manifest until you actually need the tracking.

The Future of Extended Battery Solutions
Looking forward, several trends might impact the extended battery case market.
Potential Apple Redesign
Apple could theoretically release a new Air Tag with larger internal batteries or wireless charging. If that happens, extended battery cases become obsolete overnight. However, Apple prioritizes thinness and minimalism, which argues against major battery upgrades. The next Air Tag is probably 3-5 years away at minimum.
Solid-State Batteries
Solid-state batteries promise 2-3x energy density compared to traditional lithium batteries in similar form factors. If these become mainstream in consumer electronics, future extended battery cases might use solid-state cells, achieving 15-20 year lifespans in smaller form factors.
Integration with Smarter Cases
Future cases might include temperature sensors, motion detection, or wireless charging. A case that not only extends battery life but also provides additional Air Tag features would be compelling. Elevation Labs or competitors might develop such cases within the next 2-3 years.
Regulatory Pressure on Battery Recycling
As electronic waste becomes a concern, regulations increasingly mandate recyclable or returnable batteries. This might incentivize Apple or accessory makers to redesign cases for easier battery swapping, making extended battery solutions even more practical.

Comparison Table: Extended Battery Options at a Glance
| Option | Battery Life | Cost | Form Factor | Waterproofing | Best For |
|---|---|---|---|---|---|
| Standard Case | 12 months | $5-10 | Slim | Variable | Daily-use Air Tags |
| Elevation Labs Time Capsule | 10 years | $16-23 | Larger (4.45") | IP69 | Long-term tracking |

Conclusion: Is the Time Capsule Right for You?
The Elevation Labs Time Capsule isn't a universal solution, but it's an excellent solution for specific use cases. At the $16 sale price, it's worth seriously considering if you're tracking anything for longer than 3-4 years.
Here's how to decide:
Buy the Time Capsule if:
- You're tracking a vehicle or equipment for years without frequent replacement
- You're installing multiple Air Tags and want to minimize battery maintenance
- You travel frequently and want peace of mind without battery worries
- You're using Air Tags for business or fleet tracking where downtime matters
- Environmental impact concerns you and reducing battery waste is attractive
Skip the Time Capsule if:
- You're tracking keys or a wallet you'll probably lose or replace within 2 years
- You prefer slim form factors and can't accept the extra bulk
- You're on a tight budget and prefer paying for batteries as needed
- You already have a reliable tracking system and this is just a backup
- You prefer the convenience of rechargeable solutions
The $16 sale price tips the decision toward "buy it." The worst case is you buy a Time Capsule, use it for a few years on luggage or a vehicle, and the battery outlasts the item you're tracking. That's not wasting money; that's peace of mind.
But the real value comes from actually using the 10-year battery life. If you buy the case and then attach it to an Air Tag that you lose or replace within a year, you've paid extra for capability you never tapped. That's the risk.
Measure your actual use case. How long do you realistically keep the item you're tracking? How often will you access it? What would happen if the battery died? If the timeline is years and the stakes are meaningful, the Time Capsule earns its price tag. If the timeline is months, standard batteries are sufficient.
The broader lesson is that accessory choices matter and should match your actual usage patterns, not theoretical ideals. The Time Capsule is a smart solution for a real problem, but only if you have the problem it solves.

FAQ
What is the Elevation Labs Time Capsule?
The Elevation Labs Time Capsule is an extended battery case for Apple Air Tags that uses two AA lithium batteries instead of the standard CR2032 coin cell. It provides up to 10 years of battery life, approximately 14 times longer than standard Air Tags. The case is waterproof (IP69 rated), fiber-reinforced for durability, and sealed with four corner screws.
How does the Time Capsule extend battery life?
The Time Capsule works by replacing the single CR2032 battery with two AA batteries, which collectively hold roughly 3,000 milliampere-hours of energy compared to the CR2032's 220m Ah. Built-in voltage regulation maintains the correct output voltage as the batteries discharge. This dramatic increase in energy capacity, combined with efficient regulation, extends battery life from approximately 12 months to 10 years under normal use conditions.
What type of batteries should I use in the Time Capsule?
Elevation Labs specifically recommends Energizer Ultimate Lithium AA batteries. These lithium batteries maintain voltage more consistently as they discharge and provide better performance in low-drain devices compared to standard alkaline batteries. Using the recommended battery type ensures you achieve the full 10-year lifespan. Generic lithium AA batteries from other brands may also work, but performance could vary by 10-20%.
Is the Time Capsule waterproof?
Yes, the Time Capsule has an IP69 waterproof rating, which is the highest waterproofing classification available. This means the case withstands high-pressure water jets, sustained submersion, temperature extremes from 0°C to 80°C, and even salt spray in coastal environments. For vehicle Air Tags, luggage trackers, and outdoor equipment, this waterproofing provides excellent protection against environmental exposure.
How often do I need to replace the batteries?
Elvation Labs claims the batteries last approximately 10 years under normal use. In practice, battery lifespan varies based on how actively your Air Tag broadcasts. A vehicle Air Tag sitting parked most of the time might last 12-15 years, while an Air Tag on frequently-moved items might last 7-8 years. Most users should expect between 8-10 years before needing battery replacement.
What is the actual cost of ownership compared to standard batteries?
Over 10 years, the Time Capsule costs
What happens if I use alkaline batteries instead of lithium?
Alkaline AA batteries will technically work in the Time Capsule, but you'll see noticeably reduced battery lifespan and potentially spotty performance. Alkaline batteries lose voltage more dramatically as they discharge, which can cause the voltage regulator to work harder and reduce overall efficiency. You might see 5-7 years of lifespan instead of 10. For the minimal extra cost of lithium batteries, it's not worth the performance compromise.
Is the Time Capsule worth it for tracking keys or a wallet?
For items you access daily and might lose or replace within a few years, the Time Capsule is probably overkill. Standard battery cases are adequate, cheaper upfront, and don't add unnecessary bulk. The Time Capsule shines for items with long ownership lifespans, like vehicles, luggage for long-term storage, or business equipment. Consider the realistic lifespan of the item you're tracking before deciding.
How does the Time Capsule compare to solar charging cases?
Solar charging cases theoretically offer unlimited battery life, but in practice, they're unreliable. Solar panels generate minimal current on an Air Tag case, requiring direct sunlight exposure 6-8 hours daily to meaningfully supplement battery life. Most users see modest improvements (18-24 months instead of 12) rather than permanent solutions. The Time Capsule's predictable 10-year lifespan is more reliable than solar's variable performance.
What makes the $16 sale price special?
At the standard
Can I use the Time Capsule with any Air Tag model?
The Time Capsule is designed specifically for the standard Apple Air Tag (the circular device). It's not compatible with Air Tags built into other Apple products (like those in Air Tag Card or future integrated Air Tags).
