Apple's AirTag is extremely useful when it comes to tracking down lost or stolen items, with many stories detailing how it's helped reclaim personal property. However, while it's small and handy, its battery life can be a problem.

The AirTag uses a CR2032 battery, and that cell lasts for about a year before you need to change it out. While this isn't a massive problem when using it on a keyring, it can be a struggle to regularly replace if it's in a well-hidden and hard to access spot, such as underneath a vehicle.

To solve this problem, ElevationLab has come up with the TimeCapsule AirTag Battery Case. A rectangular fiber-reinforced composite enclosure designed to encase the AirTag's main body, and to supply power to it too.

Users have to remove the battery and door from an AirTag before placing it inside the case. Along with the AirTag, the case has space inside its 4.45-inch long, 1.57-inch wide, and 0.75-inch thick casing to hold two AA batteries, which supply power to the AirTag.

The result is a 14-times increase in battery life, with a claimed lifespan of up to ten years. However, this does rely on the batteries being good quality, and not degrading or otherwise failing for such a long period of time.

Using four CNC-machined screws to hold the case together, it's also fully waterproof with an IP69 rating.

TimeCapsule is available now from the company's store and Amazon, starting from $19.99 for one unit. A two-pack is available for $29.99, and a four-pack is $39.99.
