The cells and traction batteries offered by SIAP are available in DlN and BS standards. Depending on the workmanship technology, we offer traditional acid cells and batteries with liquid electrolyte (APH, BS) and cells and batteries with silica bonded electrolyte, so-called gel cells and batteries (EPZV, EPzV/BS).
Both types of the cells have ”armoured” positive plates in which the positive active mass is in a multi-tubular housing, substantially increasing the plate’s useful life. The negative plate is a classic grid pasted with negative active mass. The plates are separated by means of a sleeve separator pulled over the positive plate. The sleeve separator effectively eliminates the risk of a lateral short circuit.
The gel cell elements (cores and grids) are made with lead-calcium alloy. The appropriate lead alloy, silica bonded electrolyte and the valve adjusted by the cell’s internal pressure placed in the plug cause that the gas emission from such cells is scarce. The batteries composed of gel cells are applied wherever the use of classic acid cells is restricted by health and safety or sanitary rules. The application of gel cells reduces the time necessary for their maintenance, As the adjustment of the electrolyte density is not necessary, any accidental electrolyte leakages are prevented.
