MARATHON FRONT TERMINAL
From the World Leader in VRLA Battery Technology
Designed for durability in Telecommunications, and Electric Utility applications, the GNB Front Terminal MARATHON™ series provides high performance and reliability in long duration discharge applications.
The location of the terminals on the front (vs.the top) of the battery greatly facilitates the installation and maintenance of the product when placed in a cabinet enclosure or on a standard relay rack tray. The MARATHON™ Front Terminal battery series highlights another example of GNB ’s extensive experience and worldwide leadership in VRLA technology.
