The EUROPOWER® EVL series batteries are made in AGM technology (Absorbed Glass Mat) and have electrolyte absorbed in glass fiber separators. Their design life ranges from 6 to 9 years. The EVL series are batteries designed specifically for use in UPS systems. With standard dimensions they are characterized by much smaller internal resistance. As a result, the EVL series has a larger capacity and very good constant power and high current discharge characteristics , especially for short back-up times (5-20 minutes).
