• Deep cycle AGM technology
• Plus carbon technology
• Lead calcium grids for extended life.
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. 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 HPC series batteries incorporates the very latest oxygen recombination technology to effectively control the generation of gas during normal use.
Sterling’s HPC series batteries are manufactured using a range of terminals which vary in size and type. Please see datasheet in downloads tab.
Valve Regulated Design
The batteries are equipped with a simple, safe low pressure venting system which releases excess 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.
Standby use: Float charging voltage 13.5V to 13.8V. (Temperature compensation recommended)
Cyclic use: maximum charging current (see front page). Charging voltage 14.4V - 15V.
Top charge: Product in storage (ambient temperature) required a top charge every 6 months at 25oC (77oF). For higher temperatures, time intervals will be shorter.
Stop operation when voltage has reached the minimum permissable voltage; recharge immediately.
Always store battery in fully charged condition.
Store batteries in a dry and cool location.
For standby use, batteries should be kept in an ambient temperature of 25oC.
• Do not short circuit
• Do not charge in a sealed container • Service life and operational characteristics will be affected by temperature
• AC ripple reduces service life
