Prostar 2 Volt GM Series lead acid battery is made of individual cells each providing 2 Volt. By combining multiple cells, batteries of nearly every voltage and capacity can be made. Depending on the capacity of the cell, one, two or four connection points for the positive and negative connections are available. Due to the flexible design, the final shape of the battery can be adapted to the space available. The cells can be placed in any direction, creating a system with all connections on the front so it enables easy checking of individual cell voltages and the torque of the connections.
AGM (Absorbed Glass Mat) sealed battery technology was originally invented in 1980, and developed and introduced in 1985 for military aircraft where power, weight, safety, and reliability were paramount considerations. The Concorde AGM batteries are VRSLAB (Valve Regulated Sealed Lead-Acid Battery), sometimes referred to as VRLA (Valve Regulated Lead-Acid).
2 volt AGM VRLA battery banks are available in a wide range of 2v battery cells, from 100 Ah to 3000 Ah, configured to customer required voltages, standard modules are 24v or 48v battery banks. These are rechargeable Lead Acid Battery banks made up of 2 volt vrla cells used for power backup in solar with an incredibly long cycle life.

1) Nice Appearance
European Low Profile style & streamline shape design gives the battery elegant look.
2) Longer Service Life
Unique plate elongating self absorbed technology can effectively prolong the service life.
3) Maintenance-Free Operation
Absorbent Glass Mat (AGM) technology ensures efficient gas recombination up to 99% and freedom from electrolyte maintenance. During the expected float service life of Prostar batteries, no need to check the specific gravity of the electrolyte or add water.
4) Longer Float Service Life
A unique corrosion-resistant grid alloy & special lead paste formulations ensures the batteries have excellent recovering ability upon over discharging and longer float service life.
5) Low Self Discharge
Using high purity raw materials ensures Prostar batteries have less self-discharge.
6) Environmental & Non-polluting
Gas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out.
7) Safe & Reliable
Efficient venting system automatically release excess gas when the pressure rises above the normal level & reseals the valves when it returns to the normal rate, which can protect the battery from bursting.
