ElevationLab makes a battery case for your AirTag that can power it for 10 years and the accessory is on sale now for 30 percent off. Normally retailing for $23, you can pick one up for $16.
The TimeCapsule case uses two AA batteries to offer up to 14 times the lifespan of the CR2032 battery that powers an AirTag. The company based those estimates on Energizer Ultimate Lithium batteries, so your mileage may vary. Once an AirTag is seated inside the case, which is a compact 4.45 x 1.57 inches, it is sealed shut with four screws at the corners. The case is fiber-reinforced, according to Elevation Lab, and rated IP69 waterproof.
