Application Information

STT / OPzS Series 20 year Lead-Selenium Tubular Flooded Plate Battery.
Manufactured in accordance with OPzS DIN40736 standards.

Construction Information

Lead Selenium/Low-Antimony

By utilizing a small amount 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 which is one of the most common causes of cell failure.

A lead selenium cell combines the advantages of both lead calcium and lead antimony cells while exhibiting none of the disadvantages.
