STEP 1 DESULPHATION
Detects sulphated batteries. Pulsing current and voltage, removes sulphate from the lead plates
of the battery restoring the battery capacity.
STEP 2 BULK
Charging with maximum current until approximately 80% battery capacity.
STEP 3 ABSORPTION
Charging with declining current to maximize up to 100% battery capacity.
STEP 4 PULSE
Maintaining the battery at 95–100% capacity. The charger monitors the battery voltage and
gives a pulse when necessar y to keep the battery fully charged.
