## Description

70mAh LSSP031420AB Battery Replacement Intended for Fitbit Charge HR Smart Activity Tracker and Fitness Watch FB405.

Review: direct fit, worked - Worked well, until the fit bit went through the washing machine...so really cant comment on the longevity of it
Review: Solved Fitbit charge HR - So if you get that dreaded battery icon with the exclamation point in the middle, regardless of all the online resetting and firmware update failures, it’s your battery that is dead! 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. Revised rating.
