Step 1 — Fitbit Charge HR weak Battery Repair / Replacement tutorial
- Inside your Fitbit Charge HR
Step 2 — Tools needed to replace Fitbit Charge HR battery
- You’ll need some plastic bits to separate the band, plus a torx driver, new battery and a soldering iron.
Step 3
- This repair only works on the Fitbit Charge HR model, not the older Charge without heart rate. The batteries are different.
Step 4 — Separate the band from the electronics casing
- Start by removing the 4 torx screws
Step 5 — Take your time and be careful of the fragile plastic
- 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.
Step 6 — A small torx driver is required.
- Once removed, there are 2 torx screws holding the circuit board in place. Remove these, and carefully pry the board out
Step 7 — Prepare to solder!
- The Fitbit is very light and hard to hold, so it is recommended to tape the board in place when soldering.
Step 8 — Understand the risk to your device.
- 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 !
Step 9 — Test your work before you re-assemble.
- 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.
To reassemble your device, follow these instructions in reverse order.
