Nickel-Cadmium Battery Discharging

Nickel-cadmium (NiCd) batteries should be discharged to 1-volt per cell before they are recharged to avoid reduced runtime following the next charge. The runtime of nickel-cadmium batteries that have been recharged before being discharged to 1-volt per cell can be restored by discharging them to 1-volt per cell, recharging them, and then repeating that deep discharge/recharge cycle two more times. It is easy to design nickel-cadmium battery-life restoration circuits that perform that deep discharge/recharge cycle three times automatically. ©2004 Martek International All rights reserved.
