if you have the manual dexterity and intellect to replace the battery on a Fit bit Charge HR, why can't you do it on. "Charge" plain model I have 3 of these with dead batteries?

The battery on the original Fitbit tracker is different than the newer Fitbit HR. If you can find a battery that fits, it would work.

Where can I buy a replacement battery for my charge hr? Fitbit wants me to buy a new Fitbit which is inexcusable since the watch is only 16 months old

They sell them on Amazon for $10.95. Has only one review for 2 stars. Trying to decide if I should order one. Caveat emptor!

Scott McKernon -

Can you give me the size of the battery?
