Distilled water is typically the best liquid to add to lead-acid batteries. It’s essential to maintain the proper electrolyte level in lead-acid batteries to ensure optimal performance and longevity. Over time, as the battery goes through charge and discharge cycles, water in the electrolyte can evaporate, leading to a decrease in electrolyte level.
Adding distilled water helps replenish the electrolyte and maintain the appropriate concentration of sulfuric acid, which is essential for the battery’s operation. Using distilled water is important because it lacks impurities and minerals that can affect the battery’s chemistry.
Avoid using tap water or any other type of water that may contain minerals or impurities, as these can interfere with the battery’s performance and lead to premature failure. Always follow the manufacturer’s recommendations regarding the proper electrolyte level and maintenance procedures for your specific lead-acid battery.
