SBS "SR" series batteries are long-life, stationary batteries suitable for short discharge at high current and high capacity discharge over longer periods. They are used as back-up power supplies in power stations, nuclear power stations, substations, UPS, industrial equipment, and engine starting applications.
The SRs lead selenium cells represent the best possible compromise in lead acid pasted plate technology. The two most popular alloys used in current pasted plate cells utilize either antimony or calcium as a hardening agent in lead alloys. Both of these additives produce desirable and undesirable effects on the performance and overall life of a battery. However, by utilizing a proportion of selenium in the grid alloy, a dense fine grain structure is produced. This alloy is extremely corrosion-resistant and virtually eliminates inter-granular corrosion one of the most common causes of cell failure. A lead selenium cell, therefore, combines the advantages of both lead calcium and lead antimony cells while exhibiting none of the disadvantages.
