The p26a are …unwrapped , and I wasn’t careful pulling them off the charger…there was a big spark and the display went dead. I assume it’s toast since I think I grounded the positive and shell of the battery to the charger while the negative was still touching on the other end….
Swapped power supplies from one to the other, nada
I don’t know why you are messing with unwrapped batteries - especially charging them. The only time my batteries are unwrapped is right before I rewrap them.
I think people generally overly cautious about batteries but unwrapped batteries are dangerous. It’s very easy to short them.
