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).
