At a Glance
- Superb recovery from deep discharge.
- Gas Recombination.
- Multipurpose: Float or Cyclic use.
- Lead calcium grids for extended life.
- Great Replacement for APC RBC 31 kits.
This APC RBC31 Equivalent Sterling Battery is the perfect replacement for many APC systems.
Sterling's unique construction and sealing technique ensures no electrolyte leakage from case or terminals.
Electrolyte Suspension System
This HPX series battery 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 of the HPX series battery incorporates the very latest oxygen recombination technology to effectively control the generation of gas during normal use.
Valve Regualted 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.

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.
