Battery Photo:

MUST 2v 400ah battery are mainly big capacity batteries with voltage of 2V. It use advanced micro porous absorbed glass matt separator - minimizes diffusion of oxygen into the separator, reducing float charge current which suppressed the corrosion rate of the positive grid and extends the life of the battery.


1. Nice Appearance: European Low Profile style & streamline shape design gives the battery elegant look. 

2. Longer Service Life: Unique plate elongating self absorbed technology can effectively prolong the service life. 

3. Maintenance-Free Operation: Absorbent Glass Mat (AGM) technology ensures efficient gas recombination up to 99% and freedom from electrolyte maintenance. During the expected float service life of 2v400ah battery , no need to check the specific gravity of electrolyte or add water.

4. Low Self Discharge: Using high purity raw materials ensures 2v400ah battery have less self-discharge. 

5. Longer Float Service Life: A unique corrosion-resistant grid alloy & special lead paste formulations ensures the battery have excellent recovering ability upon over discharging and longer float service life. 

6. Environmental & Non-polluting: Gas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out.
