What can be used as a substitute for battery replenishment fluid?

Distilled water can be used as a substitute for battery replenishment fluid. In cases where the battery fluid is low, either battery replenishment fluid or distilled water can be added. Tap water and purified water contain certain minerals and should not be used as substitutes for battery replenishment fluid. Lead-acid batteries are chemical reaction devices composed of positive and negative plates, separators, and a solution containing sulfuric acid, used for storing and discharging electricity. A battery, also known as an accumulator, is a type of cell that works by converting chemical energy into electrical energy. The normal service life of a battery ranges from 1 to 8 years, largely depending on the condition of the vehicle. If the vehicle's alternator charges normally and there are no electrical leaks or grounding issues, the battery can last more than 3 years.
I've been driving for decades, and it's common for the battery fluid to decrease. I always use distilled water as a replacement, just buy bottled ones from the supermarket—cheap and convenient. The key is to use pure distilled water; never use tap water or mineral water, as the impurities can corrode the battery plates and cause the battery to fail prematurely. For example, during the hot summer when evaporation is fast, I regularly check the fluid level and add distilled water if it's low, pouring it slowly with a funnel to avoid spills. Remember to wear gloves and goggles for safety to prevent accidents. With good maintenance, the battery's lifespan can be extended. I check the terminals and clean off dust every quarter. In short, experience shows that as long as the liquid is pure, distilled water is the best substitute—saving money while learning a few handy tricks.
