Full discharge for a 7.2-V NiCd is about 6 volts. Taking it below 6 volts can damage it by causing some of the cells to become reverse-charged. Because of electrochemistry, the voltage of a battery never falls to zero. As a battery discharges, the voltage charges somewhat, but the main change is that the internal resistance goes way up, so that the battery loses its ability to deliver substantial amounts of current. -- ------------------------------------------------------- Michael A.
