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
