Query: Works like it should

The cheap charger that came with my 9.6v drill died after several years. I was about to buy the exact replacement when I saw this one for a few bucks more. This charger is soooo much nicer than the cheapo charger that comes with the drill. This charger charged one of my batteries in less than an hour, and it showed that my 2nd battery was bad.
