Mahajan Enterprises offers automotive batteries manufactured by Global Battery Co Ltd, Korea. They are featured with centred cast-on plate straps which are stronger than the thinner gas-burned conventional connectors and reduce the lever action movement resulting from road shock. The exclusive patented liquid gas separator prevents electrolyte losses by collection and returning liquid to the reservoir, and the vents allow the battery to breathe during temperature changes and charging. The flame arrester prevents the explosion from stark of outside, minimises the acid-leakage and prevents the inflow of dust. There are heat-sealed covers which prevent contamination and also add to the strength and rigidity, include permanent flame arresters to prevent and accidental explosion from external sparks or flame and have hydrometer built-in for faster checking. The electrolyte specific gravity is 1.280 while at 50% of charge considered the minimum serviceable condition the specific gravity is typically 1,220. In a typical situation when the specific gravity drops to 1,100, the battery is fully discharged.
