  • Low Antimony plate alloy. The specially formulated plate alloy, combined with the increased cell head space, minimizes the water consumption of the batteries, while on the same time extending the watering intervals.
  • Minimal maintenance costs. Thanks to the longer watering intervals, the maintenance costs of the battery are significantly lower.
  • Reduced expected repair costs. The low water consumption minimizes damages caused by low water conditions.


  • Bolted connections making repair and maintenance a breeze.
  • Available in 3 different versions according to the required watering intervals:
