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. … Put the vent caps back onto the battery.
Will water hurt a car battery?
Wait for it… nothing, nothing happens to a car battery when it gets wet, mostly. The battery is a sealed unit and the terminals are made of lead which doesn’t rust. … Anyway, the water inside dilutes the acid and the effectiveness of the battery is weakened.
What happens if you put water on a car battery?
| Adding too much water to your car battery
Over filling the battery causes the electrolyte to overflow out of the battery cells. Electrolyte is corrosive and can cause damage to the battery and surrounding equipment. Also adding too much water can dilute the electrolyte solution resulting in poor battery performance.
Can a 12 volt battery get wet?
Continual exposure to freshwater will break down the battery with rust and slow, discharge rates. If you notice that the battery is submerged in freshwater, you should react in the same way as saltwater. Dry the housing and terminals. Marine batteries will always be negatively impacted by any type of water.
Will a wet battery still work?
Therefore, if water enters the cell and is kept around the terminal, it could induce the battery to malfunction. … It is recommended to immediately dispose of batteries that have made contact with water to prevent the failure of the cells and the subsequent appliances they are used in.
How do I know if my battery needs water?
To get the most out of your car battery life you should understand how to check if the water is low. Usually there is a clear “eye” on the top of the battery that displays a green light if the water level is good and a dark light if the battery needs water. Be sure to use distilled water.
What kind of water do you put in a battery?

What happens if a battery is low on water?
Low water level means the electrolyte will be out of balance and the battery cells will become too acidic resulting in sulphation on the battery plates. The non-conductive lead sulphate crystals will hinder flow of current through the electrolyte.
How full of water should a battery be?
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.
