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 !

After replacing the bad battery, plug

replacement.
