How long do you charge a Black and Decker 18-volt battery?
I have four Black and Decker 18-Volt Firestorm batteries. I’ve been charging them on the simple wall charger for about three hours each. They charge but I just think they should last a little longer than they do in my drill, circular saw, flashlight, and weed eater. (all interchangable black and decker 18 volt products) Am I charging them too much or too little?
