CHARGING PROGRAMS
STEP 1 DESULPHATION
Detects sulphated batteries. Pulsing current and voltage, removes sulphates from
the lead plates of the battery restoring the battery capacity.
STEP 2 SOFT START
Tests if the battery can accept charge. This step prevents charging a defective bat
-
tery.
STEP 3 BULK
Charging with maximum current until approximately 80% battery capacity.
STEP 4 ABSORPTION
Charging with declining current to maximize up to 100% battery capacity.
STEP 5 ANALYSE
Tests if the battery can hold charge. Batteries that cannot hold charge may need
to be replaced.
STEP 6 RECOND
Choose the Ca/Ca program to add the recondition step to the charging program.
This step can also be selected separately by choosing the BOOST-program. During
the recondition step voltage increases to create controlled gassing in the battery.
Gassing mixes the battery acid and gives back energy to the battery.
STEP 7 FLOAT
This step maintains the battery voltage by providing a constant voltage charge. This
step can also be selected separately by choosing the SUPPLY-program where it is
possible to select different voltage settings. Follow battery manufacturers recom
-
mendation.
STEP 8 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.
