Standby and Reserve Batteries

The Technology – Sterling’s high integrity valve regulated lead acid (VRLA) batteries operate as a starved electrolyte system, in which the electrolyte is limited to the amount that either is absorbed in the batteries plates or wets the fibres in the separator. The resulting system allows gases produced during overcharge to diffuse from one plate to the other and to be recombined back into the electrolyte.

This recombination creates a closed system, thus reducing the release of gases into the atmosphere under normal discharge conditions.

Since the electrolyte is recycled, there is no need to add water to the batteries. This reduced maintenance leads to longer-life battery in a clean and compact container that can be installed when flooded batteries are impractical.

Features & benefits

  • Tank formed construction allows for individual plates to be inspected prior to battery assembly, eliminating manufacturing defects. Plates are fully formed guaranteeing 100% capacity on delivery.
  • Sterling’s unique construction and sealing techniques ensures no electrolyte leakage from case or terminals, allowing batteries to be positioned on their side.
  • Excellent recovery from deep discharge.
  • Low self discharge – approx 3% per month.
  • Not restricted for air transport – complies with IATA ICAO special provision A67.
  • Impact resistant ABS case and cover
  • Industry standard footprints for easy field replacement
  • Maintenance free
  • 98% recyclable
