STEP 1 DESULFATION
Detects sulfated batteries. Pulsing current and voltage, removes
sulfate from the lead plates of the battery restoring battery
capacity.
STEP 2 BULK
Charging with maximum current until approximately 80 % bat-
tery capacity.
STEP 3 ABSORPTION
Charging with declining current to maximize up to 100 % bat-
tery capacity.
STEP 4 FLOAT
Maintaining the battery voltage at maximum level by providing
a constant voltage charge.
STEP 5 PULSE
Maintaining the battery at 95–100 % capacity. The charger
monitors the battery voltage and gives a pulse when necessary
to keep the battery fully charged.
