Manufacturing Process of REVAN UPS Tubular Battery

The manufacturing process of REVAN UPS tubular battery starts with the production of the positive grid with the High Pressure Die Casting Machine which is usually a series of fifteen parallel lead rods or spines cast on to a bar. This is fabricated from a low Antimony Selenium Lead alloy. Following this, 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 the Vibratory Filling Machine. 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 refrigerated 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.
