Second chance in new condition:
The WATTSTUNDE 12-50 12V AGM battery 50 Ah C20 has a high cycle stability and therefore has a long service life even when used in combination with solar panels. High vibration resistance and slope resistance ensure reliable operation even in harsh conditions.
The WATTSTUNDE 12-50 12V AGM battery 50Ah C20 is a valve controlled and maintenance-free VRLA battery. The electrolyte is bound in a fiberglass mat (AGM = Absorbent Glass MAT) so that virtually no gas formation occurs. This also makes use possible in closed spaces or in the vicinity of people. Another advantage of the AGM technology: due to the leak resistance, it is possible to install the battery in every possible position (not just horizontally), thus guaranteeing the highest installation flexibility.
The amount of energy that can be extracted from a battery depends to a large extent on the period in which the battery is discharged. This is represented by the so-called C value. The number after the C describes the discharge time in hours. The faster the battery is discharged, the smaller the usable amount of energy. With a discharge within 10 hours (C10) 43,7 Ah is available, but if the battery is discharged within 20 hours (C20), 50 Ah is available.
