Prostar GM500-2 deep cycle vrla 2v 500ah agm battery cost

AGM has very low internal resistance, is capable to deliver high currents on demand and offers a relatively long service life, even when deep cycled.

SKU: GM500-2 Category:

Prostar GM500-2 deep cycle vrla 2v 500ah agm 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.

2v battery cells from the world’s leading manufacturers independently sourced, giving you the customer the advantage of knowing that you are being offered the correct battery for your application. At Pb Batteries we pride ourselves on making sure we help you identify your current battery or requirement and supply you with the correct product.

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).

Prostar GM500-2 deep cycle vrla 2v 500ah agm battery has a lifespan of between three and five years, based this calculation on several factors including the number of loading/unloading cycles and environmental factors.

Some advices to maximize batteries lifetime:

Make sure to keep the batteries in a cool, dry and well ventilated location. Ideally, the temperature of the site should not exceed 24 degrees Celsius. For good ventilation, there must be a space between batteries to ensure adequate air circulation.

Do not store batteries for long periods of time. New batteries can be stored for 6 to 12 months. After this period, the battery should be used or a large percentage of their carrying capacity will be lost. It is not recommended to storage batteries that have already been used.

When using batteries in a UPS, does not exceed 80% of its rated capacity due to decreased autonomy – when the load increases, the autonomy decreases. In case of power failure, a UPS with a load equivalent to full capacity consumes and discharges the batteries quickly, reducing its lifespan.
