 Smart battery charger, 9 State Charger, 12V/24V Battery charger



A Smart battery charger packed with useful features to quickly and safely charge your battery but also maintain and improve the life of your batteries.

A fully automatic 9 state charger for 12 or 24V lead acid (Wet cell, Gel cell, AGM) and lithium iron phosphate (LiFePO4) batteries.

Advanced diagnostics enables this unit to maximise charge rate while also maximising battery life.

The charger outputs 12V up to 7.2A and 24V up to 3.6A with 9 states of operation including multi-stage charging for 12V and 24V batteries.

The additional desulphation and recondition modes help in extending battery life.

By far one of the most versatile chargers for cars, 4WD, trucks, or boat applications.



So in my opinion ...  having a smart battery charger to kepp your battery in  optimal condition is paramount.

Automatic and Intelligent 9-Stage Charging Curve

The MB3613 is controlled by a microprocessor with 9-stage charging characteristic for charging batteries automobiles, motorcycles, snow mobiles, tractors, personal watercraft, boats etc.

A microprocessor senses the condition of the battery 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:

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 discharged, 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 Normal 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 voltage and gives a pulse when necessary to keep the battery fully charged


Power Supply: MB3613 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 from –20°C to +45°C.

A high temperature environment will lower the voltage and freezing condition is handled by higher voltage.

A low temperature heightens the output voltage, and hot condition is handled by lower voltage.


Voltage compensation

Because of some voltage drop in the cables, the actual voltage at the clamps of the battery can be lower than the charger output voltage.

A special circuitry inside the unit will monitor the true input voltage to the battery and adjust the output voltage of the unit accordingly. This will maximise the charging efficiency.

Reverse-polarity protection.

This unit offers reverse-polarity protection under charging modes, the RED LED will illuminate and the charging process will not start.

If this happens, unplug immediately from mains, connect the red clamp to positive (+) battery post, and black clamp to negative (-) post, then plug into the mains power and the charging process will start.


Short-circuit protection

Should you accidentally touch the clamps together whilst the mains power is on, the unit will not perform charging. Unplug from mains, disconnect and start the process again being careful not to touch the clamps together.


Charge Memory

If power off on charging, MB3613 can automatically restart charging base on previous power down status for battery and charging current.


ATTENTION: Once the clamp of charger is disconnected from the battery, this memory is erased and the charging mode will need to be reselected.


Other features

  • Anti Spark Protection
  • Battery and Charger Overheating Protection
  • It will give a warning buzz while error occurs
  • Waterproof Plastic Housing.
