This is an absolute longshot, but from the days of card edge connectors in computers I remember this trick. It looks like from your photo you might have some discoloration on your battery contact. Try a sharp edge or a pencil eraser and clean the contacts both sides and then try again with a known battery.
Good luck-remember I said it’s a longshot.
