The Switch is powered by a standard, 3V Lithium Cell CR2032 coin battery.
You can check if the battery in the Switch needs replacing from the RVMaster App's General Settings. Open the Battery Levels page in the Settings menu, then press any button on the Switch you want to check the battery of. The RVMaster App will refresh with the Switch battery status.
If you need to replace the battery:
- Unclip the Switch Button Pad.
- Using a flathead screwdriver, pry open the Switch Button Pad and remove the battery from the holder.
- Insert the new battery in the holder with the positive side facing up.
