3 days agoElevation Lab's 10-year extended battery case for AirTag is back on sale for $16
Still, if you're looking for an AirTag case that you can place in a suitcase or backpack and not have to touch for years, this could be the ticket. Elevation Lab says that, when you place a couple of AA batteries in the case, it can extend the tracker's battery life to as much as 10 years (the brand recommends using Energizer Ultimate Lithium batteries for best results). The AirTag is slated to run for over a year on its standard CR2032 button cell.
