# How do I replace the batteries?

|| Please note! We advise using **only lithium AA batteries** in Myndr Switches. [Read more here](/en/article/recommended-batteries-vsus8u/)
The Myndr Switch runs on 2 AA batteries (LR6). In the [dashboard](https://admin.myndr.net) you can see at any time how full the batteries still are. When the batteries need replacing, the switch gives 4 beeps when you turn it.

Replacing the batteries works as follows:

1. Detach the switch from the wall plate by sliding the device upwards. You will feel some resistance until the switch clicks loose from the plate.
1. Take the old batteries out of the switch. The best thing to do with old batteries is to hand them in at [a collection point near you](https://www.legebatterijen.nl/inleveren/waar-inleveren/).
1. Put 2 new AA batteries in the switch. Pay attention to the orientation of the plus and minus poles. The battery compartment shows which side the plus and minus poles go. The left battery goes with the plus facing up. The right one goes with the plus facing down.
1. Hang the switch back on the wall plate by inserting the 2 guides of the switch into the 2 slots of the wall plate and sliding the switch downwards. You will feel a clear click.
1. After about a minute, the switch works again.
