OPzS / STT
SBS has been selling tubular lead-selenium vented batteries for nearly 20 years. SBS was the first company to actively introduce this technology to the US market.
The combination of the tubular positive plates and the lead selenium/ low antimony alloy provides the best possible combination in lead acid plate technology.
The battery world favors tubular positive plates for flooded, gel and AGM applications. STT batteries are manufactured in accordance with OPzS DIN 40736 standards.
STT batteries are manufactured in accordance with OPzS DIN40736 standards.
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.
Due to increased positive plate surface area, tubular plates have more electrical capacity than flat plates of comparable size and weight.
With positive plate shedding eliminated, tubular batteries also provide up to a 30% longer service life compared to flat plate batteries.
Perhaps most importantly to stationary applications, the tubular positive grid does not require horizontal bars, which virtually eliminates positive plate growth and therefore post seal leaks and jar cracking. As a result, in applications which require a long service life, tubular plate batteries provide the best and most reliable power.
