VRLA AGM replacement battery

The BatteryJack PowerStar is a sealed valve-regulated lead-acid battery built with absorptive glass mat technology. It serves as a direct OEM replacement for UPS units, alarm panels and standby power systems. The maintenance-free design eliminates watering or specific-gravity checks. Buyers who need lithium chemistry or higher energy density should look elsewhere.

Sealed non-spillable construction

The case and terminal seals prevent electrolyte leakage in any mounting orientation. Classification as non-spillable allows air transport under IATA rules. Gas recombination exceeds ninety percent during normal float service. No provision exists for adding water or performing internal maintenance.

Maintenance-free float operation

The battery is designed for continuous float charging with a projected service life of four to seven years. Recombination of generated gases keeps internal pressure stable without venting. No active cooling or thermal management is required in typical cabinet installations. Power draw is limited to the float charge current of the host equipment.

Questions about this item

What battery technology does the PowerStar replacement use and what maintenance does it require?

It uses Absorptive Glass Mat (AGM) technology with a sealed construction that recombines over 90% of generated gas, so no water top-ups or specific gravity checks are needed during its service life.

What physical design allows the battery to be mounted in any orientation?

The sealed, non-spillable case prevents electrolyte leakage from the terminals or housing, making it safe to operate in any position and classified as non-spillable for air transport.

How is the battery installed and what common step should be avoided?

Install as a direct 100% OEM replacement; because it is maintenance-free with no provision for watering, do not attempt to open the case or add electrolyte.
