The charger I used was for AA battery's and its a good one so it would not even try to work if something was wrong. On the other hand I was just looking to see if the light came on at all, that way I would know to look into that more or not.
So I guess they will work in the pila for now I just might want to charge outside for safety where its a little cooler and the door is open like you where saying. I did have it closed, but I can see why its best to leave open. Should be good to go. Thanks again.
