The MPG range VRLA batteries use flat plates with gel electrolyte and a front terminal design. The design makes installation simple and safe on a standard relay rack tray or in a closed cabinet. The MPG range has a high energy density and suits 19″ and 23″ racks and cabinets, with options for top connection and side-of-monobloc connection. A central gas collection system can be fitted to the customer’s requirements. The design float life is 12 years at 25 °C (77 °F).
