This charger can greatly increase the life of any NiCd battery. Tests have proven that it is not unusual to achieve one thousand or more charge cycles when using a four stage Minus Delta V charging method. The same tests have shown older batteries will recover substantially by reducing crystallization and restoring the battery to near normal performance.
Cool-Lux MaxPower Belts use nickel-cadmium (NiCd) cells that are voltage-matched for every belt. This is called cell balancing. Cell balancing allows all the cells to charge and discharge at the same rate, preventing premature battery failure. It is an expensive, time consuming quality check, but one that is extremely important. It ensures that every cell performs to optimal performance.
