PowerFlex Technology
Charging NiCad/NiMH batteries is generally accomplished by applying constant current to the battery.
SKC PowerFlex Chargers use a technology that is new to industrial hygiene equipment batteries.
Refl ex charging
†
delivers pulses of current instead of constant current to charge batteries. In between
pulses, PowerFlex applies short reverse pulses that discharge the battery slightly and short pauses.
This eases the battery into a full and uniform charge. It helps to prevent dramatic increases in internal
temperature and pressure that can damage the battery and shorten its life.
† Patented by Galaxy Power, Inc.
Note: Discharging the pump battery before charging is not necessary with this system
because the charging technology does not promote memory. However, if the user
desires to discharge before charging, simply run the pump until it stops, then
charge the battery.
