# How long do the batteries last?

Alkaline batteries last about 1 year, depending on use of course. Lithium batteries are expected to last up to 4 times longer. We recommend lithium, because the switch works more reliably with it. You can see the status of your batteries in the [control panel](https://admin.myndr.net/cp/manager).
