D250SE CHARGING PROGRAM LEAD-ACID

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.
