OPERATING MODES OF THE CHARGING UNIT
This powerful charging unit provides the following operating modes:
a. Charge the rechargeable battery (CHARGE) – to charge the rechargeable battery,
automatically switches to trickle charge after the rechargeable battery is full.
b. Discharge then charge the rechargeable battery (DISCHARGE) – to discharge the
rechargeable battery then charge it to minimize the memory effect.
c. Refresh the rechargeable battery (REFRESH) – to refresh the rechargeable battery to
its maximum capacity by charging and discharging the rechargeable battery repeatedly
until no further increase in the capacity is estimated. For old rechargeable batteries or
those have not been used for a long time, refreshing may bring the rechargeable
battery back to the optimum condition.
d. Check the rechargeable battery capacity in mAh/ Ah (TEST)
