I got a new battery for my caanoo - now the old battery has some life in it still so I want to place it in another gadget..the thing is: does someone have a suggestion how to unglue it from the backplate w/o destroying the battery?
Depends what sort of glue it is. It may well be some sort of hot glue, so leave the backplate somewhere warm for a while, then have a go at it with some nylon guitar plectrums is my go to removal gadget of choice.
