Batteries are used by electric utility companies to back up switchgear equipment. For example, if part of the utility grid is disabled because of a failed transformer or downed cable, the switchgear needs to be operable so that switches can bypass the outage and provide power to other parts of the grid. The batteries also provide power to other critical control equipment.

Flooded batteries have been the traditional choice of electric utilities. However, the obvious benefits of Valve-regulated, lead-acid (VRLA) batteries are allowing VRLA batteries to make significant inroads into this market. The increased safety, reduced maintenance, reduced floor space requirements, and configuration flexibility of VRLA batteries offer real benefits to utilities.

GNB Absolyte� IIP batteries are a great fit for utility applications requiring a relatively large amount of back-up. These batteries offer reduced service and maintenance, the ability to be stacked to reduce floor space, and minimal gas evolution. Ranging in capacity 105 amp-hours to 4800 amp-hours, GNB Absolyte IIP batteries are available in several configurations including the standard modular configuration, the "relay rack" configuration, and as single-cell modules for maximum configuration flexibility.

GNB's Marathon VRLA batteries are an excellent choice when less back-up power is required. These 6-volt or 12-volt monoblock batteries are available in capacities from 28 amp-hours to 180 amp-hours. GNB Marathon batteries offer the highest power density of any battery on the market today.
