Exide GELMagic 150AH Inverter Battery, Feature : Enhance Recharging Efficiency.

A VRLA Gel battery utilizes a one way, pressure-relief valve system and Gelled (immobilized) electrolyte to achieve a recombinant technology. Gelled Electrolyte is formed by addition of silicon dioxide (SiO2) to diluted Sulphuric acid (H2SO4). Fused gelled electrolyte not only acts as electrolytic medium for ion movement but also provides infinite small crevices necessary for recombination reaction. Oxygen normally produced on the positive plate is transported to negative plates through crevices formed in fused gel and it is then absorbed by negative plates. This surpasses the production of hydrogen at the negative plates. Water (H2O) is produced instead, retaining the moisture within the battery. It never needs watering, and should never be opened as this would expose the battery to excess oxygen from air.
