Bharat Battery Tubular Batteries have the spines or the positive plate support cast at high pressure (100 bar) in imported HADI machine which ensures void free structure and consistent grain orientation and can protect the plate support from anodic corrosion. This in turn ensures higher reliablility and longer life. Bharat Battery Low Maintenance Tubular plates are also cast with low antimony content which reduces the topping up frequency, making the batteries low maintenance type. This also keeps the float charging current at a lower value, thus minimises the total energy requirement needed to keep the battery in charged condition during standby float application.
