Submarine Batteries

HBL has developed the design and manufacturing technology for a wide range of submarine batteries. The product superiority comes from a fully equipped modern facility that has machines for Pressure die casting of low antimony tubular spines, forming and plating copper stretch metal, Resin transfer moulding of high shock resistant fiber glass containers and a fully automated cell test facility.
The positive tubular plate electrode is made by pressure die-casting using a low-antimony lead alloy. The cell cover is made of high quality Glass-fiber Reinforced plastic (GRP). It is resistant to dilute sulfuric acid and is designed for demanding standards of shock resistance.
