STEP 1 WAKE UP
Read section about batteries with "under voltage protection" on previous page.
STEP 2 ACCEPT
Tests if the battery can accept charge. This step prevents that charging proceeds
with a defect battery.
STEP 3 BULK
Charging with maximum current until approximately 90% battery capacity.
STEP 4 ABSORPTION
Charging with declining current to maximize up to 100% battery capacity.
READY TO USE
The table shows the estimated time for empty battery to 80% charge.

STEP 5 ANALYZE
Tests if the battery can hold charge. Batteries that can not hold charge may need to be
replaced.
STEP 6
Not applicable.
STEP 7 FLOAT
Maintaining the battery voltage at maximum level by providing a constant voltage charge.
STEP 8 PULSE
Maintaining the battery at 95–100% capacity. The charger monitors the battery voltage
and gives a pulse to keep the battery fully charged.
