| Product Description :
||Tubular Battery is designed with the positive plate which is composed of a series of parallel tubes filled with lead oxide. This is usually fabricated from 6-10% antimonial lead alloy. Following the casting process, a series of parallel porous glass fiber tubes are fitted over the grid spines, these tubes are then filled with a mixture of lead oxide and red lead powder by vibration. Once the tubes are filled, they are sealed by knocking a plastic fitting onto the ends of the lead grid spines. The resulting assembly is then “pickled” by soaking in dilute sulfuric acid to convert the lead oxides to lead sulfate. The finished product comprises a series of tubes filled with lead sulfate with a center core of lead to carry the current.
