# Aluminum AirTag Case Prolongs Battery Life with AA Lithium Batteries
Apple’s AirTag has gained popularity as a tool for monitoring personal belongings such as keys, bags, and even cars. Nonetheless, its dependence on a typical CR2032 coin cell battery, which usually lasts around a year, can be a drawback for users who place AirTags in hard-to-reach spots. Introducing the **TimeCapsule**, a new offering from Elevation Lab that claims to extend AirTag battery life to an astonishing 10 years by substituting the coin cell with two AA lithium batteries.

## **What is the TimeCapsule?**
The TimeCapsule is a $20 aluminum case engineered to house an AirTag while substantially enhancing its battery longevity. The case replaces the original back plate and coin cell battery of the AirTag with a waterproof enclosure that supports two AA batteries. Elevation Lab asserts that employing **Energizer Ultimate Lithium AA batteries**—recommended for this product—yields 14 times greater power capacity compared to the standard CR2032 battery.
The case is machined from aluminum using CNC technology, ensuring both durability and an elegant appearance. It specifically targets users who position AirTags in vehicles, boats, or other settings where frequent battery replacements are inconvenient or challenging.

## **How Does It Function?**
To operate the TimeCapsule, users need to:
1. Take off the AirTag’s back plate and CR2032 battery.
2. Position the AirTag into the TimeCapsule’s contact points.
3. Insert two AA lithium batteries into the enclosure.
Designed to be waterproof, the case is suitable for outdoor or rugged conditions. Elevation Lab promotes the TimeCapsule as a solution for situations in which AirTags must operate for prolonged durations without maintenance, such as tracking equipment, vehicles, or other valuable possessions.

## **The Inspiration Behind the TimeCapsule**
The concept for the TimeCapsule reportedly stemmed from the inventor’s personal experience. After having camera gear stolen, they realized the AirTag affixed to it had ceased functioning months prior due to a dead battery. This event underscored the necessity for a more durable power solution, prompting the creation of the TimeCapsule.

## **Possible Use Cases**
Although the TimeCapsule’s larger design may not be optimal for everyday applications such as keychains or pet collars, it excels in specific situations where prolonged battery life is essential. Examples include:
– **Vehicles and Boats:** AirTags secured in cars, motorcycles, or boats can take advantage of the extended battery life, particularly if the vehicle is stored for long stretches.
– **Luggage and Bags:** Travelers aiming to keep tabs on their luggage during extended journeys may find the TimeCapsule advantageous.
– **Outdoor Equipment:** Gear like bicycles, camping supplies, or tools kept outside can reap the benefits of the waterproof and enduring design.

## **Potential Issues and Limitations**
### **Size and Practicality**
The larger dimensions of the TimeCapsule, due to the AA batteries, render it less feasible for compact items such as keys or wallets. However, for bulkier objects or stationary usage, the compromise may be worthwhile.
### **Anti-Stalking and Privacy**
Some users have expressed concerns regarding the potential implications of the extended battery life on AirTag’s anti-stalking functions. AirTags are engineered to notify nearby iPhones when they are separated from their owner for too long, and as of a 2023 update, Android phones can now automatically detect AirTags. While these features remain functional, a prolonged battery life could arguably facilitate misuse by malicious individuals.
### **Unverified Battery Claims**
Although the idea of utilizing AA lithium batteries to prolong battery life is technically viable, the assertion of achieving a 10-year lifespan has not been independently confirmed. Elevation Lab has not published thorough specifications or testing results to substantiate this claim, although the company has indicated it is based on the capacity of the suggested batteries.

## **DIY Options**
The introduction of the TimeCapsule has ignited conversations among tech enthusiasts about crafting similar devices. On platforms like Hacker News, users have proposed designing DIY battery extensions using **CR2032 dummy cells** linked to external battery packs. While this strategy necessitates some technical expertise, it could offer a cost-effective alternative for those inclined to modify their AirTags.
—
## **Closing Thoughts**
The TimeCapsule presents an inventive approach to enhancing the battery life of Apple’s AirTags, especially for users with targeted needs like tracking vehicles, equipment, or other high-value items. While its larger size and unverified battery assertions might discourage certain users, the concept of utilizing AA lithium batteries for increased lifespan is both practical and thought-provoking.
For users who often depend on AirTags in demanding settings or for long-term tracking purposes, the TimeCapsule could represent a significant advancement. However, as with any new offering, prospective buyers should consider the advantages against the drawbacks and assess whether the extended battery life merits the investment.
