Keep in mind that daily usage, all day sync, heart rate monitor set to “on” instead of “auto”, and other factors may decrease the time needed between charging.



If your Fitbit has water damage, endless Fitbit “resetting” & power cycling, or other issues, then a new battery will not help you. Also, please note that if you install the new battery and only get 6-12 hours of life, then there is an underlying issue with the Fitbit that a new battery will not fix.

  13. Russ Wigglesworth

    When my daughter’s FitBit died she was prepared to drop some serious cash to fix/replace it. I took a look on YouTube and found Tanin’s instructions on battery replacement. I figured for less than $10 it was worth a try. Came in 2 days and took me all of 20 minutes to change the battery. FitBit is as good as new! Thanks!

    Placed my order and received shipping email next day. Item arrived shortly after that. Quick and easy ordering on the website plus I received a free torque screwdriver.

  15. Lobonation

    I needed a replacement for a fitbi charge and even though this one looked a bit smaller and thicker than the original, it fit fine and the instructions in youtube from the same vendor helped a lot. oh, and the torx tool was a must-have for this. Thanks

  16. Robert Phillips

    The battery was delivered in a timely manner and was what I purchased. I just wish I would have soldered better so I didn’t destroy the circuit board while attempting to connect the wires. Oh well, will save up until I can afford a new Fit Bit. lol

  17. James Wen

    Quick mail with detailed instructions.

  18. Michael

    Shipped quicky. Battery wasnt exact same size but fit anyway. I installed it and it holds a charge for 3-4 days. JUST LIKE NEW. Protest money theiving throwaway electronics and order this product now. I lncluding a free torx is great because they are difficult to find.

  19. Irving Ellner

    Battery and tool arrived quickly. Instructions pointing to youtube video helped significantly. Completed Fitbit battery replacement with no problems. A happy customer.
