Looking for this battery as well; mine lasted exactly 1 year. 7 days now down to hours, the surge did the same thing, maybe my last Fitbit watch ever! Disappointed to say the least.

Darrell Way - crwdns2934203:0crwdne2934203:0

I found a battery, 3.7 volt at 165mAh in the same style, should be close enough but I do not have the size of the factory battery, if anyone has taken theirs apart, can you post up the measurements in mm? thanks

Darrell Way - crwdns2934203:0crwdne2934203:0

I can't find the battery anywhere either. Would love some advice. Tried Amazon, AliExpress, eBay and Google in general.
