Hey, I recently organized all my batteries and some are brand new, some are charged fully and some I have used and just taken them out of my lights after use . Anyway I forgot to label them so I know which ones are fully charged and which ones need charging and/or topping up. There is 18650,tenergy ds, and rcr123s ! Would it hurt them if I charged them and the ones that were full wouldn't get damaged? Don't want to cause danger or ruin the batteries?
