This repair only works on the Fitbit

Charge without heart rate. The
batteries are different.

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 !

To reassemble your device, follow these instructions in reverse order.
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.
