Key Features

GNB Flooded Classic® NXT 2-volt battery cells are an industry-proven power solution for telecommunications, electric utility, industrial UPS, and other long-duration discharge/general-purpose applications. GNB’s Flooded Classic NXT batteries combine features of long duration and high rate batteries to give excellent one minute rates as well as superior long duration performance (50 to 2600 amp-hours). These batteries are the right choice for utility switchgear and control applications that typically have complex duty cycles (e.g. high inrush currents at the start of a discharge followed by lower steady-state rates).

GNB Flooded Classic® NXT Batteries

GNB Flooded Classic® MCT 2-volt and 4-volt batteries are industry-proven power solutions for telecommunications and other long-duration discharge applications. The GNB Flooded Classic MCT battery is meant for telephone company central offices and other applications requiring constant current or constant power for longer than two hours.

GNB Flooded Classic® MCT Batteries

Vented Lead Acid batteries are most commonly used in central office applications or sites with a high capacity demand and a large allowable space for the battery system. 300-4000 Ah per battery equating to up to 8,000 Watts per cell. Flooded cells provide a much longer lifespan than their equivalent VRLA batteries but also require more maintenance than their VRLA counterparts.
