D250Sa Charging Program - CTEK D250SA Manual

D250SA CHARGING PROGRAM

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 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.
