I need one of the battery guru's to help with a question I have about protected batteries. I have been told that a protected battery just means that it won't overcharge and the way to test if a battery is protected is to put it on a charger for 10 days. A protected battery will be fine and an unprotected battery will be dead? I am thinking that an unprotected battery will explode? I have been going back and forth about a battery that I don't think is protected, yet the supplier claims it is. There is no visible protection circuit on this battery, but the supplier claims that this is a new kind of protection that doesn't use a circuit board. Any help with this would be greatly appreciated!!
