Fitbit Charge HR Battery Replacement

ID: 66358

Description: This is a simple tear down & repair tutorial...

Steps:

1. Inside your Fitbit Charge HR

2. You'll need some plastic bits to separate the band, plus a torx T3 driver, new battery and a soldering iron.

3. This repair only works on the Fitbit Charge HR model, not the older Charge without heart rate. The batteries are different.

4. Start by removing the 4 torx screws

5. 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.

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

7. The Fitbit is very light and hard to hold, so it is recommended to tape the board in place when soldering.

8. 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 !

9. 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.
