The MB3908 is a battery charger with a pulse trickle charge mode and is suitable for charging and maintenance charging of the following 12 V or 24 V lead rechargeable batteries with Wet, Gel, AGM and 12.8V 4-cells LiFePO4:


• 12 V: with a capacity of 18 - 240 Ah 

• 24 V: with a capacity of 10 - 120 Ah 

• Lithium (12.8V 4-cells LiFePO4): with a capacity of 10 - 80 Ah 


You can also used it to regenerate completely discharged batteries. 

The battery charger has protective circuits to prevent sparking and overheating. Any incorrect or improper use leads to loss of the warranty. The manufacturer takes no responsibility for damage(s) arising out of usage that is contrary to the instructions laid down. The appliance is not meant for commercial use.


 Product 10 Step features:

This appliance has been designed for charging a variety of SLA batteries (sealed lead acid batteries), as mainly used in cars, motorbikes and several other vehicles. 

They may be of types e.g. WET (with liquid electrolyte), GEL (with mit gel-type electrolyte) or AGM (absorbed glass mat) batteries. 

A special design of the appliance (also named: Ten-phase-charging strategy“) enables the recharging of the battery to almost 100 % of its original capacity. 

Connecting the battery for a long period to the battery charger is also a good way of ensuring that your battery is kept in optimum condition. 

The “ten-phase-charging strategy” as follows: 

Step 1: Check Checks the battery voltage to make sure battery connections are good and the battery is in a stable condition before beginning the charge process. 

Step 2: Recovery Initializes the Recovery process, if needed, for deeply discharged or sulfated (desulfation) batteries by pulsing small amounts of current. 

Step 3: Soft Start Slow charge and protect for deeply discharged or sulfated (desulfation) batteries by multi -phase of current. 

Step 4-7: Bulk The Bulk charging process continues using both a High Rate and Medium Rate charge and returns 80% of battery capacity, Indicated by the 20%, 40%, 60%, 80% and 100% LCD. 

Step 8: Absorption Brings the charge level to 80%, The battery charger will deliver small amounts of current to provide a safe, efficient charge and limit battery gassing.

Step 9: Maintenance 1 

Battery is fully charged and ready to use, indicated by the 100% CHARGE LCD and the fact that the battery icon stops flashing. In this step, the battery charger will only deliver enough current to keep the battery full. If the battery tells the charger that more current is needed, the battery charger will switch to Maintenance. 

Step 10: Maintenance 2 

Continuously monitors the battery voltage to determine if a maintenance charge should be initiated. If the terminal voltage falls below 12.8V (12V) and 25.6V (24V), the charger will start the Maintenance cycle until voltage reaches 13.6V (12V) and 27.2V (24V) and then discontinues the charge cycle. The cycle between Trickle and Maintenance is repeated indefinitely to keep the battery at full charge, without overcharging. The battery charger can be left connected indefinitely.




No need to wait for a Mechanic and pay an expensive fee.
If you have a good quality Battery Charger with you then you will not need to wait.

You will be able to rejuvenate your battery yourself in no time.
