I have a brand new cordless drill battery - never used. Model 8500, 1 hour fastcharge 12 volt rechargeable battery. It is for Porter*Cable drills model #'s - 850, 851, 852, 853, 854 & 855. This battery is currently backordered on many tool websites. I had to special order it only to find out that my charger doesn't work either and I'm better off just buying a new drill (BTW the drill is for sale, too).
Thanks for looking,
