Drill - Power Performance cordless 24v (Highfield NE39)

This is my old Power Performance 24v hammer drill. It has 2 x 1.3Ah nickel cadmium battery packs which do not hold their charge for more than a few hours, so need charging up before a job. So I've now got a new drill! Also the chuck slips when drilling using round drills. Works well on all hexagonal shanks such as screwdrivers. Variable speed, torque control and hammer action. Its about 12 years old.
