Northstar Front Terminal NSB125FT HT Red Battery is a premium AGM battery designed for emergency backup in float applications where there are semi-stable mains. These batteries have a long shelf life of 2 years and a design life of 10-15 years. These batteries are best suited for applications where the power-grid is unstable and heavy cycling and high power are required.

The NSB HT Red battery employs our pure lead – high temperature (TPPL-HT) technology and is designed to provide superior life (7 years) and high performance at an operating temperature of 40ºC (104ºF), regardless of the quality of the electric grid.

The HT Red battery offers a high cycle life of 800 cycles to 50% DOD with optimum charging and a recharge time of 4 hours from 50% SOC to full charge. This is the battery you need when you want both long life and durable cyclability at high temperature.
