The electrolyte solution in a lead-acid battery consists of approximately 35% sulfuric acid and 65% water. The acid concentration is usually between 4.2-5 mol/L, and the solution has a density of 1.25-1.28 kg/L. The electrolyte solution plays a vital role in the battery’s operation.
Lead acid batteries consist of flat lead plates immersed in a pool of electrolytes. The electrolyte consists of water and sulfuric acid. The size of the battery plates and the amount of electrolyte determines the amount of charge lead acid batteries can store or how many hours of use. Water is a vital part of how a lead battery functions.
Adding too much water to a lead acid battery will result in the dilution of the electrolyte where each overflow results in a reduction of 3-5% of the battery’s capacity resulting in reduced performance. Using an electrolyte monitor will prevent all of this from happening by showing you exactly when a battery needs water.
One of the most important factors to consider when it comes to lead acid battery maintenance is the water level. Keeping the battery hydrated means that you will have to water your battery regularly. Putting too much water in the cells reduces capacity and conversely not watering them often enough does internal damage both of which are undesirable.
You can automate the checking process by using an electrolyte monitor which will give you a visual indication of when a battery needs to be filled. It is important to note that you should never add sulfuric acid to a lead acid battery. It is both dangerous and extremely harmful to the internal workings of the battery.
In a functional lead-acid battery, the ratio of acid to water should remain close to 35:65. You can use a hydrometer to analyze the precise ratio. In optimal conditions, a lead-acid battery should have anywhere between 4.8 M to 5.3 M sulfuric acid concentration for every liter of water. How do you properly refill a battery with acid?
How Much Acid Should Be in a Battery
The amount of acid in a battery is crucial to its performance and longevity. Maintaining the right acid levels is essential for optimal functioning. Generally, the acid level should be between 25% and 30% for lead-acid batteries. This ensures proper electrolyte balance and helps prevent sulfation, which can hinder battery performance. It is ...

What is the Ratio of Acid And Distilled Water in Battery?
With that said, here is a general guide on how much acid to add to different types of batteries: These batteries typically use sulfuric acid, which should be added at a rate of about 1.5 pounds per gallon of water. So, for a standard car battery (which is usually around 10 gallons), you would need to add 15 pounds of sulfuric acid.
