SBS STT Series Flooded Wet Cells
Available from Storage Battery Systems, LLC
SBS "STT" series batteries are 20-25 year stationary batteries and were developed for utility, telecom and general purpose applications. They are distinguished by their lead selenium tubular plate design and high tolerance to cycling.
The STT's tubular lead selenium cells provide the best possible compromise in lead acid plate technology. 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.
