Professional auto mechanics and car battery manufacturers recommend using pure water such as deionized water or distilled water for filling car batteries. In case of an emergency and there are no readily available sources for deionized water or distilled water, use rain water instead when possible. | Adding too much water to your car battery
Is it safe to pour water on a car battery?
What happens if you put water in a car battery?
Don't Over Water
If too much water was added before charging, the electrolyte levels will expand and cause the battery to overflow and damage the battery. Additionally, excessive watering of a battery can result in additional dilution of the electrolyte, resulting in reduced battery performance.
Can I pour water on my battery terminals?
Cover the battery terminals and other corroded areas with a coat of baking soda. Then pour a small amount of water on each terminal. You'll notice the two ingredients react with each other when they start bubbling. If you need to, repeat the same process on the battery cable ends.

Where do you add water to a car battery?
How do I know if my battery needs water?
Some batteries have a clear battery indicator “eye” on the top that glows green if the water level is good and fully charged, and goes dark if the battery needs fluid or is discharged. If it's yellow, it usually means that the battery fluid level is low, or the battery is defective.
What kind of water do you put in a battery?
The most common type of water used in batteries is distilled water. Other types are deionized water and water from reverse osmosis. Ordinary tap water should not be used because it may contain an excessive amount of impurities that will degrade battery performance.
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.
Can a battery get wet?
It is dangerous for a battery to get wet in most cases. When the battery is submerged in water, the water gets inside then mix with chemicals and leaks out. The chemicals that leak out through holes can cause health hazards. For example, it burns the skin in case of contact.
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.
Can your alternator get wet?
Yes. Again, alternators are designed to handle water. If your alternator got wet and isn't working, the problem is likely a wet diode or something similar. Give your car 24 hours to dry out using the tip above, and your alternator should be good to go.
How do you clean battery poles?
How often top up battery water?
Overtime you will notice a pattern to when you refill the battery, and this will give you the frequency for the future. So, if you check every week, but only need to add water every sixth week then your watering interval will be every six weeks and you can start to increase the intervals between your inspections.
Do modern car batteries need water?
Car batteries also known as SLI (starting, lighting, ignition) batteries don't require water very often if ever. To get the most out of your car battery life you should understand how to check if the water is low. Do not use tap water as the minerals could react negatively with the battery chemistry.
How do I add water to my everstart battery?
What happens if car 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.
Can you use bottled water instead of distilled water in a battery?
Because tap water contains minerals and natural content that could corrode the battery, it's best to used bottled water. Use distilled or deionized water to fill your battery, as it doesn't contain the mineral content of tap water.
How full of water should a car 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.
Do you add water to a battery before or after charging?
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.
Is distilled water the same as battery water?
Never fill a battery with normal water. It will damage your battery. You need to use distilled water. You let the tap water flow in, the resin filters the metals and minerals out of the water and you're left with the deionised, demineralised, distilled water that's suitable for use with your battery.
What can I use instead of distilled water?
4 Substitutes for Distilled Water
What happens if a 12v battery gets wet?
All water, however, is corrosive.
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. Marine batteries will always be negatively impacted by any type of water.
Why is my car battery wet on top?
When a car battery leaks acid, it is usually through the cell caps on the top of the battery, or due to damage to the body. Under such conditions the battery acid inside may begin to freeze and cause the body of the battery to expand, putting pressure on the cells, similar to water pipes that burst in winter weather.
How do you rejuvenate old car batteries?
Does rain affect car battery?
The humidity levels present during heavy rains may contribute to corrosion forming at the battery connections, but such conditions rarely affect battery function, or internal components. However, a car battery may seem to grow weaker as rainy day travels persist.
Can I wash my alternator?
Cleaning the alternators is pretty good to help maximize its performance. Nevertheless, it would be best if you do not pressure wash the alternators. Doing so can cause some serious damage to the seal, which would be bad for the car. You can rinse the alternator with some water but endeavor you let it dry too.
