To fully charge any storage battery a certain amount of overcharge is necessary. This overcharging equalizes the power in the cells of the battery. As each cell reaches 80% of capacity it dissipates the surplus energy by boiling. This causes the water in the electrolyte to separate into hydrogen and oxygen gases which vent from the battery and reduce the electrolyte level. Distilled water must be added to make up the loss or your battery could be ruined. HYDROCAPS catalytically recombine the hydrogen and oxygen gases into pure water and return it to the cell. This reduces watering and washes the electrolyte spray back into the battery extending its useful power. The danger of hydrogen gas explosion is virtually eliminated and corrosion is stopped because the acid spray and fumes are contained.
