With a legacy spanning over 95 years, Ramcar brings unparalleled expertise to the creation of the SuperCharge, meticulously crafting it in world-class facilities located in the Philippines. The SeaMaster marine battery range, crowned as the industry leader, incorporates revolutionary Expanded Grid Technology (EXG), setting new standards for marine batteries.

What sets EXG apart? The advantages are manifold. The construction of calcium plates in super-compressed rolled strips forms a dense grid pattern, resulting in a more compact unit. This design minimises susceptibility to heat corrosion while enhancing cranking power efficiency. Notably, the EXG plates, being shorter with minimal gassing, reduce water loss, eliminating the need for acid top-ups.

In contrast to ordinary gravity-cast grids, EXG calcium grids exhibit a more compact grain structure, inherently fortifying them. This structural superiority renders them less vulnerable to heat and corrosion, ensuring efficient current conductivity and superior cranking power. These claims are substantiated by the battery's exceptional specification ratings, reinforcing its status as the pinnacle of marine battery technology.
