Description
The electrolyte is bound in a gel using dryfit technology, the valve-regulated design returns gases to recombination, and no water has to be added over the whole service life. Tolerance to deep discharge matters where mains outages last for hours and the battery is discharged almost completely. The design life is 15 years for blocks from 20 Ah, and under the EUROBAT 2015 classification the series belongs to the "more than 12 years" group. The blocks comply with IEC 60896-21/22 and have UL and DNV GL approvals, so they are accepted on marine installations too. The model range runs from A412/20 G5 to A412/180 A in the 12 V version, with the 6 V A406/165 added to it. The A400 FT version has terminals on the front panel, and the blocks are connected and monitored from the front without pulling out the shelf.
How to choose
Selection starts with the battery bus voltage and the C10 capacity, and then one calculates how many 12 V or 6 V blocks to put in a string. The FT version is taken when the battery is accessible only from the front. If the UPS or fire alarm requires VdS approval and the capacity is calculated at C20, the A500 series of 25–200 Ah is closer. For capacities up to 3286 Ah and a service life of 20 years for 2 V cells at 20 °C the A600 (OPzV) is used, and solar systems with cycling duty are built on SOLAR blocks of 27–230 Ah with a life of 800 cycles at 60 % DoD.
