This Deep Cycle AGM range with Plus Carbon Technology from Sterling has superb recovery from deep-discharge, and is multipurpose in constant float or cyclic usage meaning it is brilliant for off-grid applications. AGM stands for Absorbent Glass Mat. In these batteries the electrolyte is absorbed into a glass-fibre mat between the plates by capillary action. AGM batteries are more suitable for short-time delivery of very high currents (engine starting) than gel batteries.


  • Sealed Construction - Sterling’s unique construction and sealing technique ensures no electrolyte leakage from case or terminals.
  • Electrolyte Suspension System - All HPC series batteries utilise Sterling’s unique electrolyte suspension system incorporating a microfiber glass mat to retain the maximum amount of electrolyte in the cells.
  • Control of Gas Generation - The design of HPC series batteries incorporates the very latest oxygen recombination technology to effectively control the generation of gas during normal use.
  • Valve Regulated Design - equipped with a simple safe low pressure ventilating system which releases excess gas and automatically reseals should there be a build up of gas within the battery due to severe overcharge. (NB: DO NOT charge the battery in a sealed container)
