I have a Black & Decker Versa Pack screwdriver and flashlight set I really like. Lightweight and handy. But, the batteries failed some time ago, as happens with most cordless tools. After handing on the wall unused for a couple years I decided to shop price for replacement batts. $43.00 for two small batteries. Wadda waste. I'll just throw the whole set in trash and buy a small rechargable screwdriver for about $15.00 and when that fails, toss and replace. Forget the "not happy". Color me angry.
