The quick answer is no. In wet cell batteries, acid and water routinely evaporate from the batteries cells. This causes batteries to lose power and not last as long. Keeping your wet cell batteries’ water levels filled to the proper levels (roughly ¼ inch above the plates) extends the life of your batteries and makes them perform better on a single charge. Generally, golf cart owners pour in distilled water by hand with a filling bottle. A battery watering system is automatic so it eliminates the need to manually fill your batteries, which can be super convenient! On the flip-side of the convenience, battery filling systems can get a bit costly to purchase and also to maintain. Whether you fill your golf cart batteries by hand, or using a filling system, always make sure you keep your water levels properly maintained.
