Car Battery Water Levels

Before checking the water levels in your car s battery make sure to wear safety goggles and disposable gloves to protect your eyes and skin from the electrolytes in the battery.

Car battery water levels. Knowing how to properly manage the water levels in your battery can help ensure the life of your battery and help you avoid catastrophic battery failure. The proper fill level according to battery manufacturers is approximately 1 4 inch below the fill well bottom. The proper method recommended by most battery manufacturers is to add enough water so that the cell plates are completely submerged but not so much that the water is up to the battery case cell cap vents. Additionally excessive watering of a battery can result in additional dilution of the electrolyte resulting in reduced battery performance.

Do not over fill the water level. Water or electrolytes are a very important part of what makes your battery work. To know the state of charge of your battery is it worth checking the voltage of the battery. When your car battery is fully charged the water level inside the battery will be at its highest.

Add water to the battery to bring the level to just below the bottom of the cell inspection hole. We have a guide on car battery voltage that will help you to better understand the voltage reading and state of charge. Checking the water level in your car battery is an important aspect of regular car maintenance that everyone with a vehicle should do. Fill the cells with distilled water.

Put the vent caps back onto the battery. Thus as part of your car battery maintenance schedule you should check the battery water level periodically to ensure proper battery operation and engine performance. This can cause the acid water mixture to leak. Based on the assessment made in the previous step fill each cell with the appropriate amount of distilled water.

Then clean off the dirt from the top of the battery and open the ports so you can check the fluid level in each cell. The water or electrolyte inside the battery helps in the electrochemical reaction to store this energy in the battery plates.

The amount of water in combination with the size of the battery plates is what determines the amount of charge your lead acid battery will store. If too much water was added before charging the electrolyte levels will expand and cause the battery to overflow and damage the battery. You can check the battery without special tools.
