  • The assembly is briskly snapped into place. You'll need to separate the sides of the housing with a small plastic tool and your finger nail (or two plastics). Be careful, as the housing can fracture with too much force.

  • Once removed, there are 2 torx screws holding the circuit board in place. Remove these, and carefully pry the board out

  • The Fitbit is very light, and hard to hold, so I recommend taping the board in place when soldering.

  • Note: You can permanently damage your device. Be careful with the assembly, and splice one or both wires before removing the old battery to prevent a short. Do not mistake the round buzzer for a battery. It is not !

  • After replacing the bad battery, plug in the charger for at least 20 minutes. Then remove the charger to confirm you have a working replacement.

i found that the T2 torx screw forks much better and fit more accuratly then the T3.

if you have the manual dexterity and intellect to replace the battery on a Fit bit Charge HR, why can't you do it on. "Charge" plain model I have 3 of these with dead batteries?

The battery on the original Fitbit tracker is different than the newer Fitbit HR. If you can find a battery that fits, it would work.

Where can I buy a replacement battery for my charge hr? Fitbit wants me to buy a new Fitbit which is inexcusable since the watch is only 16 months old

They sell them on Amazon for $10.95. Has only one review for 2 stars. Trying to decide if I should order one. Caveat emptor!

Can you give me the size of the battery?
