The design principle for HOPPECKE net.power batteries is based on the use of grid plates and a fibreglass fleece as a separator in which the electrolyte is fixed.
The HOPPECKE grid | power V L (series OPzS) is a low-maintenance, vented lead-acid 2V cell in conventional technology with liquid electrolyte (dilute sulfuric acid).
