The Model RF80-H Automatic ReFLEX Charger/Analyzer is the most efficient and sophisticated instrument available for rapid, automatic charging and analyzing of nickel-cadmium (ni-cad) batteries. Designed for 11, 19, 20 and 22-cell, sintered vented-type ni-cads, the charger/analyzer uses the patented ReFLEX charging principle to give rated or better-than-rated battery capacity in 1 hour.

Reflex Charging

The patented ReFLEX charging principle is unique in that it allows most vented-type aircraft ni-cad batteries to be fully recharged in 1 hour from an unknown state-of-charge. Using the ReFLEX charging method often will result in higher-than-rated capacity in the battery. The ReFLEX charging method provides a further benefit by the interjection of depolarization pulses during charging. This reduces battery heating during charging and results in greatly improved charging efficiency over conventional methods.

Battery Analyzing

The battery analyzing function allows complete battery analysis automatically with a pre-programmed cycle, and the evaluation of battery condition both by GO/NO-GO indicator lights and by actual ampere-hour capacity readout. The charge-discharge-recharge cycle is preprogrammed to match each specific battery type and takes approximately 3 hours with most batteries. Charging is by the ReFLEX method and discharging is by regulated constant current. The GO/NO-GO point, which is also pre-programmed, can be set to any percentage of rated battery capacity.
