What happens if there is no water in car battery?

Can I add water to my car battery?

Use only distilled water when filling a car battery. Using anything other then distilled water will cause permanent failure of your battery. Add water to the battery to bring the level to just below the bottom of the cell inspection hole. Do not over fill the water level.

Do all car batteries need to be filled up with distilled water sometimes?

Not all car batteries require the water to be checked or refilled. Make sure that your battery can be opened and serviced. Maintenance-free batteries are completely sealed and should never be opened. Batteries that require regular water service often have service instructions and warning labels clearly visible.

How do you make distilled water for a car battery?

The process of distilling is simple. Heat tap water to the point that it turns to vapor. When the vapor condenses back to water, it leaves behind any mineral residue. The resulting condensed liquid is distilled water.

Do you add water before or after charging battery?

Water should always be added after fully charging the battery. Prior to charging, there should be enough water to cover the plates. If the battery has been discharged (partially or fully), the water level should also be above the plates.

How much water should be in a car battery?

The water level should be about a ½ inch above the tops of the plates to be considered in normal range. When adding more water, make sure you use distilled water. Tap water contains minerals that can diminish the performance of the battery and can increase the rate at which they self-discharge.
