This is the solution. The mini Torx screwdriver was the right size to open the Fitbit. The Plusivo soldering iron kit is necessary because it has the fine point head to delicately unsolder the battery. If you’re not comfortable with soldering then don’t attempt replacing the battery yourself. But if you’re capable, then this will restore your Fitbit. One other caveat, the Fitbit screws can be difficult to remove and strip easily. But this is the right battery.UPDATE: this battery only holds a charge for one day.
