SBS-STT Series

Economical-Vented Batteries

SBS "STT" series batteries are 20-year stationary batteries and were developed for utility, telecom and general purpose applications. They are distinguished by their economical design, lead selenium tubular plate design, and their 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.

Applications:

  • Utility (stations and substations)
  • Nuclear Power
  • Power Distribution
  • Telecom Equipment
  • UPS
  • Switchgear

Features:

  • 20-year warranty
  • Economical design
  • Watering intervals — 3 years
  • High cycle life
  • No positive plate growth
  • Improved charging efficiency
  • Withstands higher temperatures than calcium alloys
  • No premature failures due to antimonal poisoning
  • Tank formed plates
