Elevation Lab’s 10-year extended battery case for AirTag is back on sale for $16

If you’re an iPhone user who likes to keep tabs on where your stuff is, you can’t go far wrong with an AirTag. The second-gen model that Apple just released outpaces the original in every way (aside from the galling lack of a keyring hole, that is). While it’s easy enough to replace the battery in both versions of the AirTag, you might not want to have to worry about the device’s battery life for a very long time. Enter Elevation Lab’s extended battery case for the AirTag, which is currently on sale at Amazon for $16.

The case usually sells for $23, so that’s a 30 percent discount. It’s not the first time we’ve seen this deal, but it’s a pretty decent one all the same.

This is arguably one of the more useful AirTag accessories around for certain use cases. It won’t exactly be helpful for an AirTag that you put in a wallet or attach to your keys, as it’s too bulky for such a purpose — and it doesn’t have a hole for a keyring anyway. 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. 

The case gives the AirTag more protection as well. It’s sealed with four screws and it has a IP69 waterproof rating. What’s more, it doesn’t ostensibly look like an AirTag case, so someone who steals an item with one inside is perhaps less likely to realize that the object they pilfered is being tracked.

There are some other downsides, though. Since the AirTag is locked inside a case, the sound it emits will be muffled. Elevation Lab says the device’s volume will be about two-thirds the level of a case-free AirTag. However, the second-gen AirTag is louder than its predecessor, which should mitigate that issue somewhat.
