Unfortunately some batteries for my Canon Cameras a 7DMII battery, RP and 40 all got put in water for 20 minutes or so. They are now in rice. Should I a) chuck them or b) should they be fine?
I would still drop canon for your area a call/email It’s one thing taking a chance with my own camera but to advise you as I don’t know and will go the safe route I would say get new batteries
I would think they should be fine. Batteries are sealed items so I doubt water got inside them. Now if it was salt water I'd worry.
this is what i'd do. camera batteries are a bit safer, but we've had a few drone batteries at work explode, catch fire, etc.. one caught fire while charging. i'm a little bit leery about lithium ion batteries in general.
