ElevationLab TimeCapsule AirTag Battery
Thanks to their diminutive size, Apple's AirTags can be used to keep track of nearly anything. Their size also means a small battery, which only lasts about a year before it needs replacement. ElevationLab's TimeCapsule makes a tradeoff in size for a serious upgrade in power, replacing the CR2032 coin cell with a pair of AAs that will last up to ten years. Simply open up the battery area of an AirTag, pop it onto the adapter, and you're done. It's protected inside a glass-filled composite body secured with CNC machined stainless screws, giving it IP69-rated protection against water and dust intrusion, and the package is still less than five inches long and two inches wide, making it ideal for use in bags, luggage, vehicles, and any other spot where long-term tracking is needed.
