I just returned mine and got a refund.
Bonjour,
Google on my phone lets me take a picture of things and then search. These batteries are not too hard to find the on internet. The difficult part is you may need to use a “point soldering” machine to attach the battery. I found a computer repair club to help me replace batteries in Bose speaker and a drill.
