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?
If you are using a charger that is intended for the battery, you may leave it on cradle overnight to make sure you are charging it at full capacity.
If you are using a substitute charger, have it charged longer but check if the battery will get hotter than normal. If it won’t get hot, have it charged overnight.
