Why Only Distilled Water Should Go Into Your Deep-Cycle Battery

Electric vehicles that run on one or more deep-cycle batteries require watering after the batteries have undergone a full charge. According to engineers at U.S. Battery Manufacturing, a global leader in deep-cycle batteries, water is lost from battery cells by evaporation. This happens during various instances such as, the heat that occurs during the charging process, heat from weather conditions, and during equalization charging, where the electrolyte in the battery bubbles to mix the electrolyte and prevent stratification (sulphuric acid settling at the bottom of the cells) which can diminish performance. 

Checking water levels periodically maintains the health of the battery cells and according to battery manufacturers, adding the right kind of water will aid in that process. Battery manufacturers such as U.S. Battery recommend using distilled water. 

Using ordinary tap water or softened water is bad for your deep-cycle batteries, as the minerals found in the water can react with the electrolyte and minimize performance and increase sediments 

Battery manufacturers recommend checking water levels frequently, usually after charging. When filling, it’s important to use proper safety gear such as latex gloves and eye protection. Manufacturers also emphasize that it’s important to fill battery cells only with enough water to cover the cell plates, but not to overfill, as the electrolyte expands with heat and overflow. To avoid splashing or overfilling, it’s recommended to use a hand pump or battery pitcher to fill each battery cell.

Adding the right kind and amount of water in your deep-cycle battery’s cells, will ultimately keep them in top shape and extend the life and performance. For more information, visit www.usbattery.com
