Sterling VRLA Batteries

Valve Regulated Lead Acid Batteries

Sterling’s AGM 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 batteries in a clean and compact container that can be installed when flooded batteries are impractical.

Sterling Series

The Sterling H, HP and HPX Series are the perfect replacements for many applications including: stand-by power, emergency lighting, phone systems as well as many others. These series utilise Sterling's unique electrolyte suspension system incorporating a microfiber glass mat to retain the maximum amount of electrolyte in the cells. The electrolyte is retained in the separator material and there is no free electrolyte to escape from the cells. The design of this series battery incorporates the very latest oxygen recombination technology to effectively control the generation of gas during normal use. Sterling's unique construction and sealing technique ensures no electrolyte leakage from case or terminals. The batteries are equipped with a simple, safe low pressure venting system which releases gas and automatically reseals should there be a build up of gas within the battery due to severe overcharge.

Sterling VRLA batteries offer many advantages over conventional lead/acid batteries:
  • Special manufacturing techniques allow 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.

Electrolyte Suspension System

The H, HP and HPX series batteries utilise Sterling's unique electrolyte suspension system incorporating a microfiber glass mat to retain the maximum amount of electrolyte in the cells. The electrolyte is retained in the separator material and there is no free electrolyte to escape from the cells.

Control of Gas Generation

The design incorporates the very latest oxygen recombination technology to effectively control the generation of gas during normal use.

Terminals

The Sterling series is manufactured using a range of terminals which vary in size and type.

Valve Regulated Design

The batteries are equipped with a simple, safe low pressure venting system which releases gas and automatically reseals should there be a build up of gas within the battery due to severe overcharge. Note. On no account should the battery be charged in a sealed container.
