I’ve bought a HP 19C on TAS. It came with a corroded battery pack. I cleaned the battery compartment and terminals added a brand new battery pack with fresh batteries and it works fine.
Yesterday in a flea market I, luckily, found a charger HP 82066B that would work with my calculator. As it was in a bucket with other chargers and junk I have no idea if it works or not. Of course I know it has to be plugged with the battery pack inside. My question is. As I know those devices are fragile, is there any risk to damage the calculator using the charger ?

If possible, do you have the option of using an external charger for the batteries instead? Plenty of horror stories have been given about how precious calculators were sent to the great dumpyard in the sky just by an unseen bad connection, I'd hate yours to be yet another cautionary tale. I would no longer trust packs like this, as there's not a lot of protection for overvoltage in some of those older calculators.
