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. 

The heart of the Delta Force Charger is a micro-controller monitoring the battery’s vital signs, voltage current and other variables. When a battery is first connected, the charger will rapidly and efficiently charge the battery to about 70% of its capacity in the first few minutes. The cells will absorb almost all of the energy and stay cool. The charger continues until the battery reaches its characteristic Delta Slope, indicating an absolute full charge. The computer senses the beginning of the slope, terminating the full charge and shifts to a trickle.
