stored energy solutions for a demanding world

Model: AG12V50F G S e r i es
The AcmeG range front access valve regulated lead acid
batteries is designed based on the Acme series.Using the
polymer gel electrolyte with real front access structure.The
state of the art internal and external design ensures AcmeG
the high reliability and makes the installations quite simple
and safe when placed on a standard relay rack tray or in a
closed cabinet. The design float life is 12 years at 20℃(68℉).
