|Hitachi Battery uses 99.99% pure lead when compounding the lead calcium alloy. The fully automated production of the expanded grid has resulted inconsistency, low resistance and enhanced electrical current flow. The sealed maintenance free battery is suitable for long continuous use like in a high traffic condition. In addition, the upgraded battery has a higher Cold Cranking Amps (CCA) and Reserve Capacity (RC) in extreme temperatures. The improved design of the battery has proven to prevent acid leakage and gassing.
