Battery Test and Precharge (Stage 1):
Check the battery voltage to make sure battery connections are good and the battery
is in a stable condition before beginning the charge process
Desulphation (Stage2):
Detects sulfated batteries. Pulsing current and voltage, removes sulfate from the
lead plates of the battery restoring the battery capacity
Soft Start (Stage 3):
Initial battery test to determine battery condition. If the battery is severely dischar
-
ged, charger will begin the Soft Start stage. Charging starts with reduced current
until battery voltage reaches a normal condition for charge.
Bulk (Stage 4):
Major charging stage where the battery receives the majority of its charge.
During this stage the battery brought to 75 - 80% of its charge. The charger delivers
maximum current until the terminal voltage has risen to the full charge level for Nor
-
mal battery.
Absorption (Stage 5):
Completes the charge up to virtually 100% at a constant voltage. The current tapers
off after the current reached the minimum level.
Recondition (Stage 6):
Select “Recondition” mode, charged by higher voltage to recondition the sulfate of
the battery to save battery life.
Analysis (Stage 7):
Tests if the battery can hold charge. Batteries that can not hold charge may need to
be replaced.
Float (Stage 8):
Low constant voltage, minimal charge current, battery is fully charged
Pulse (Stage 9):
Maintaining the battery at 95-100% capacity. The charger monitors the battery volta
-
ge and gives a pulse when necessary to keep the battery fully charged
Power Supply:
DISCOVERY 120 has a power supply mode setting which has a constant voltage of
13.8V and current up to 5A, keep to provide power to computer system of modern
car when replacing battery (Please don’t reverse battery connection to avoid the
damage on the charger).
Temperature Compensation
A sensor will automatically adjust the charging voltage if the temperature deviates
