Query: FlexCharge Battery

A truely international battery, widely used in Europe and the Middle-East. Good for quite a few appliances besides the Skil portable drill I own. The Europeans use the battery for power screwdrivers, toys, radios, boom-boxes and etc. Only trouble is that the Ni-Cad battery has a charge memory if you don't properly discharge/use until it's flat. The old battery I had lasted for about eight [8] years.
