Product description

The Eos range of VRLA batteries uses AGM technology and is built to the IEC 60896-21/22 standard. It gives 100% capacity out of the box, can handle deep discharges, and has a design life of more than 15 years with a cycle life of more than 1200 cycles to 80% depth of discharge. Flexible connectors and several optional racking systems allow many ways of installing it. The Eos-2000 is a single 2 V cell of 2000 Ah at the 10-hour rate, for fixed and mobile telecoms, UPS, utilities and solar.
