ChARGING PROGRAm D250S DUAL
The charger starts charging the target battery when the supply voltage exceeds 13.1V for 5 sec (engine on).
The charger stops charging the target battery when the supply voltage drops below 12.8V for 10 sec (engine off).
DESULPHATION

STEP 1 DESULPhATION
Detects sulphated batteries. Pulsing current and voltage, removes sulphate from the lead plates
of the battery restoring 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.
