Can the battery be replaced?

Mine was just over a year old (barely out of warranty) when it died. The Fitbit folks were kind enough to replace it anyway once I expressed my displeasure. I'd haggle with them a bit before going the DIY route but I'm definitely keeping my old one for spare parts. Hopefully someone will point out an aftermarket battery source before I need to do that.

The screws in mine were Torx T-2, not T-3.

The button is stuck in my ChargeHR. I bought the T3 screwdriver and it is too big. Either the screws are T2 or my screwdriver is too much imprecise.

Anyone fixed a stuck button?

it definitely not T3 must be T2
