AT-21P  MS ENDUR II SERIES C&D BATTERY

The AT-21P msEndur II is the latest advancement in battery technology with enhanced features for TEL applications. By combining the service life reliability of a flooded battery with the performance energy density of a valve-regulated battery, C&D has created the AT-21P msEndur II — The True Long-Life Battery™.

The msEndur II series of batteries are unmatched in power density with space saving modular designs and have a 20-year design life to reduce the total cost of ownership.
With its much lower float current, the msEndur II yields significant electrical costs savings over its life making it the most environmentally 2V VRLA battery
