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 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.
ChARGING PROGRAM D250TS
The D250TS will charge the Starter battery in 4 steps. The last step, Pulse maintenance means that the D250TS monitors the
Starter battery to see when a new charge pulse is needed. The D250TS use this monitoring time to equalize the Service battery by
sending out a voltage of exactly 50 % of the input voltage. This prolongs the Service battery significantly and will also make it pos-
sible to connect 12 V consumers to the first battery in the Service battery string. Equalization ends when the Starter battery needs
charging or when the two batteries in the Service battery bank have the same voltage.
