VPRO 40 Ah series batteries are made in AGM (Absorbent Glass Mat) VRLA technology and are mainly designed for: use in emergency power supply systems (UPS, automation systems), solar installations and with voltage converters. They are best suited for buffer charging systems, but can also be used in applications where the batteries work cyclically. The battery has about 500 cycles, and battery life is from 5 to 8 years at a temperature of 20-25 degrees Celsius.
