High Recovery Capability

Powerstar batteries have an excellent charge acceptance and recovery capability even after deep discharge. The heavy-duty lead calcium-alloy grids in Powerstar batteries provide an extra margin of performance and service life in both float and cyclic applications, even in conditions of deep discharge.

Low Self Discharge

Because of the use of Lead Calcium grids alloy, Powerstar SLA battery can be stored long periods of time without recharge. The PowerStar SLA battery has stable and reliable performance. The battery can withstand overcharge, over discharge, vibration, and shock, and is capable of extended storage.

Low Pressure Venting System

Powerstar batteries are equipped with a safe, low-pressure venting system which operates at 1psi to 6psi, designed to release excess gas and reseal automatically in the event that gas pressure rises to a level above the normal rate. Thus, there is no excessive build up of gas in the batteries.

Gas Recombination

Powerstar batteries incorporated unique design that effectively controls generation of gas and allows recombination of over 90% of gas generated during the normal use. This low pressure venting system, coupled with the extraordinarily high recombination efficiency, make our batteries the safest sealed lead-acid batteries available.

Maintenance Free

During the expected floating service life of Powerstar batteries, there is no need to check the specific gravity of the electrolyte or add water, which means they require no maintenance service.

In fact, there is no provision for these maintenance functions.

Heavy-Duty Grids

The heavy-duty lead calcium-alloy grids in Powerstar batteries provide an extra margin of performance and service life in both float and cyclic applications, even in conditions of deep discharge.

A Heavy Duty Separator increases life, is resistant to shock and vibration to prevent shorts.

HEAVY duty plates and grids are inside the battery for durability.

UL Recognized Component

All of our Powerstar SLA batteries have already passed UL.

International Air Transport Association

Powerstar batteries are SLA factory sealed and will meet all requirements of the International Air Transport Association.
