Manufactured with state-of-the-art technology, punchgrid plates in automotive batteries are proven for better reliability when compared to conventional expanded plate batteries. Full frame grid structure provides more mechanical strength and less expansion, to prevent premature failure. Non-presence of corner spikes like expanded grid significantly minimises possibility of shorts. Straight line conductivity increases power in smaller footprint area and ensures excellent vehicle starting ability. Modern Pb-Ca-Sn alloy chemistry of plates features superior endurance against corrosion, self-discharge and electrolyte loss. Specially developed paste structure of positive plates provides consistent performance for longer life.
