I'm looking for a device i can cannibalise a 402030 3.7 v battery or something like it from, anyone got any ideas ?

I've got access to loads of scrap devices like power supplies, inverters, TVs ect.

I would use any other small battery with its own PCB on it and bond it to the outside of the case if necessary.

Maybe a poundshop item ?
