FEATURES
Automatic and Intelligent 5-Stage Charging Curve
MB-3623 is controlled by a 12-bit AD microprocessor with 4/5-stage charging characteristic for
charging batteries lawnmower, automobiles, motorcycles, snow mobiles, tractors, personal
watercraft, boats, minibus, coach, truck, etc.
A microprocessor senses the condition of the battery and controls the regulator to provide the
right current and voltage to the battery (charging characteristic). This will give the best effect
on charging and give the longest life to battery.
Charging characteristic:
Gel Cell/SLA/Regular (4-Stage)
Deep Cycle (5-Stage)
Soft Start:
Initial battery test to determine battery condition. If the battery is severely
discharged, charger will begin the Soft Start stage. Charging starts with reduced current
until battery voltage reaches a voltage suitable for bulk charging.
Bulk:
Major charging stage where the battery receives the majority of its charge. During
this stage the battery brought to 60 - 80% of its charge. MB-3623 charger delivers
maximum current until the terminal voltage has risen to the set level of:
-
7.1V (6V Battery); 14,2V (12V Battery); 28.4V (24V Battery) for Wet/ Flooded
Lead Acid, MF battery selection
-
7V (6V Battery); 14,0V (12V Battery); 28V (24V Battery) for Gel/ SLA battery
selection
-
7.2V (6V Battery); 14,4V (12V Battery); 28.8V (24V Battery) for Deep Cycle
selection.
Absorption:
Completes the charge up to virtually 100% at a constant voltage. The
current tapers off after the current reached the minimum level.
•
Boost:
(Only for Deep cycle battery) the battery is charged deeply at a constant current and
increased voltage to boost the charge capacity of the battery.
•
Float (Maintenance):
o
For “STD” selection:
The maintenance mode is charging at
constant voltage
,
keeping the batteries at 100% charge. Normal charging mode is time-limited (max 10
days) while Float mode charges indefinitely without damaging the battery.
o
For “DEEP” selection:
The maintenance mode is using
pulse charge
. When the
battery voltage reaches upper limit (varied according to temperature), the charger
will stop supplying power and until the battery drops to 13,0V, it will supply
constant current again until the battery reaches upper limit. This will go in cycle
until the charging process has been stopped manually. This keeps the battery in
perfect condition when it is not in use. The charger can be connected for months
keeping the batteries fresh.
