The charger is programmed with seven smart charging steps. It will go
through some or all steps in order to extend your battery’s life and
maximize its performance.
Standby
The charger is ready to charge.
Qualification
The charger will check the battery condition, such as voltage,
state-of-charge and health, to determine whether the battery is good for
charging. If the battery is slightly sulfated, the charger will rejuvenate
and recover the battery. As a safety measure, charging process will
begin only if the battery is above 4V.
Soft Start
If the battery is at a very low state of charge, small charging voltage and
current will be applied in order to prepare the battery for the next
charging step.

Charging Steps
Pulse
The battery undergoes the desulfation process to break down the sulfate
and to restore the battery capacity.
Recondition
This stage reactivates the battery for bulk charging after desulfation.
Bulk Charging
The battery is charged at a constant current of 1A. This stage will charge
the battery to approximately 85% of full charge.
Absorption
The charger switches to constant voltage charging. Charging current is
gradually reduced allowing the battery to absorb more power until it
achieves the 100% charged state.
Analysis
Charging stops when the battery is charged to its full capacity. The
charger will check if the charging process is successful. Voltage test will
be carried out to determine the state of charge of the battery. Based on
the result, the charger will decide whether the battery will go to the next
charging step or if it is a dead battery.
Maintenance
The battery is charged at constant voltage to maintain its full charged
state without overcharging or damaging the battery.
