Your Fiit device 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, please contact us at [email protected] and we'll send you a new battery 

Replacing your battery:

  • Open the battery cover by moving the arrow to the unlocked symbol
  • 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
