STT2V500: Flooded Tubular Battery

550 Ah (8 Hr. Rate) to 948 Ah (240 Hr. Rate) 2 Volt Battery

The STT2V500 (5 OPzS 2-500) flooded tubular battery is manufactured with lead selenium and low antimony allowing for a 20 year design life. 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.

Our STT Series batteries are manufactured in accordance with OPzS DIN40736 standards.
