Connect the AC power cord with the AC power outlet.
When the battery is connected to power supply the battery connected LED indicator
will illuminate.
The charger will automatically select the right voltage according to the battery voltage type and
the corresponding LED indicator will turn on.

3. Disconnect the AC power cord from the AC power outlet when fully charged. Then disconnect
the power cord from the battery.
Remark:
ALWAYS disconnect the power cord from the power outlet before connecting (or disconnecting)
the charger to (or from) the battery.
CHARGING STAGES
1. Diagnosis & Recovery
The unit automatically checks the battery level after connecting, a unique function - the unit
automatically checks the battery level (detects voltage) If a deeply discharged battery's voltage
is over 4.5V ± 0.5V (for 12V battery) or 16V ± 0.25V (for 24V battery), the charger begins
charging with 1.5A low current to recover it, which terminates when voltage reaches to 10.5V
± 0.25V for (12V battery) or 21V ± 0.25V (for 24V battery) at the beginning of the process, the
charger skips low current charging and it switches over to charging mode.
2. Bulk charge stage
80% of energy is returned in this stage of charging. Here charger performs in multi-stages:
