Your Fiit device / Fiit device Lite comes with a CR2032 3V battery included.
If the red and blue lights don’t flash on the front after you tap it, it could mean the batteries have died. If your Fiit device isn't working, you can change the battery in your Fiit device. We recommend the Panasonic Energizer Battery - CR2032.
To change the battery:
- Open the battery cover by moving the arrow to the unlocked symbol using a 2p coin
- Remove the battery cover and remove the flat battery for safe disposal
- Replace with the new CR2032 battery, taking care to seat the battery correctly
- Replace the battery cover and secure tightly
