Operating Modes
(Charge, Discharge, Refresh, Test)

Regardless of operation mode, the batteries will end up
fully charged.

 Charge: Charge up the rechargeable battery (it will

automatically switch to trickle charge after
rechargeable battery is full).

 Discharge: Discharges the rechargeable battery

then charges it one time to minimize any memory
effect.

 Refresh: Batteries will be discharged and

recharged up to 20 times or until the charger
cannot remove additional charge. The battery will
receive a final charge and has reached its capacity.
For old rechargeable batteries or those have not
been used for a long times, refreshing may bring
the rechargeable battery back to the optimum
condition.

 Test: Batteries are charged to full, then discharged

to measure capacity, then recharged to full.
Capacity is measured in Ah/mAh.
Note: In Discharge, Refresh and Test modes, the
discharge current will be half of charging current
selected.
