GNB batteries

This section brings together GNB batteries for industrial use. The Classic range is 12 V lead-acid with high capacity, built to power equipment for hours rather than deliver a starting burst. Each product page lists voltage, Ah, dimensions and weight so you can check them against your installation.

Before ordering, confirm how many units make up your bank and how much space you have.

How to choose a GNB battery for industrial use

An industrial battery is chosen for the work it will do, not for a vehicle. Before looking at models, decide whether it will feed backup equipment that spends most of its life on float charge, or a machine that is discharged and recharged every shift. The answer changes both the capacity you need and the way it should be charged.

Criteria that get it right

• System voltage: 24 V, 48 V or larger banks are built by linking 12 V batteries in series; every unit should be the same model and the same age.
• Capacity (Ah) and rate: always compare at the same discharge time (C10, C20…), because the figure changes with the rate.
• Space and weight: measure the rack or battery box and make sure the support can carry the full weight of the bank.
• Maintenance: flooded lead-acid needs ventilation and regular electrolyte checks.

If you need backup power, compare it as well with UPS batteries and with batteries for renewable energy storage.

Frequently asked questions

Can I mix a new GNB battery with used ones?

It is not advisable. In a series bank the weakest battery sets the limit, and the new one would end up overworked.

Can it be used to start an engine?

That is not its role. It is designed to deliver energy steadily; for starting, a dedicated starter battery is the right choice.
