The acid stays in the battery, the water is lost through evaporation or over charging. The acid in the battery never leaves it. Adding more acid will speed up the process of sulphating the plates & will soon render the battery useless.

What happens if you overfill a battery with acid?
Also an overfilled battery is more likely to leak as it is charged, so the sulphuric acid content is more likely to cause issues as it is very corrosive. It will eat any paint etc it comes into contact with and depending on the amount and its acidity, can easily start to eat into the metal bodywork over time.
Can you put too much distilled water in a battery?
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 you add acid to a dead battery?
You can also try to replace the acid inside a battery and mix a new acid with the distilled water. Then, recharge the battery for a few hours. In any case, you will get a new battery that can last for a long time.
Is it OK to overcharge lead acid battery?
Overcharging a lead acid battery can be just as harmful as undercharging it. If workers leave the battery in a continuously charging state for long periods of time, corrosion of the positive battery plates can occur. Lead acid batteries can also get very hot while charging.
How do you fix overfilled batteries?
Process for refilling electrolyte :
- Drain the battery electrolyte completely.
- Use hot water for proper cleaning (internally).
- Dry it by placing the battery in the sun exposure in the manner upside to downfaced so that it might be completely dried internally .
How much acid should be in a battery?
It is important to have the cells filled equally or the battery will not operate properly. The acid should reach a level about 3/16” below the cap ring as shown in the diagram. A newly filled battery will sometimes require additional acid after about 20 minutes.
What happens if battery cells run dry?
“If people open the cap of the battery and they see the cell is dry they will fill it up to the top,” Bohlman says. “If you fill it to that level and then you put the battery on charge, the battery expands and can cause leaks.”
When should 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.
Can I put bottled 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 do you bring a dead lead acid battery back to life?
Attach a battery trickle charger or a computerized smart charger to your old lead acid battery, and allow charging continuously for about a week to 10 days. The extremely slow charging rates dissolve the de-sulphation that kills the battery, and revives it back to being able to hold a usable charge.
Can a completely dead battery be recharged?
It is possible to recharge a dead battery, and depending upon the situation you are in, a dead battery is generally an easy fix, whether you are stuck in your garage and can handle it yourself or you are in the middle of nowhere and need professional, quick, and efficient service in the blink of an eye.
Do you have to charge a new battery after adding acid?
The stand or rest period allows the electrolyte to permeate into the plates for optimum performance. Newly activated AGM batteries require an initial charge. After adding electrolyte, a new battery is approximately 75-80% charged.
Should I hear my battery bubbling while charging?
Car batteries are lead-acid, and when they are being charged the electrolyte (acid )heats up, and will bubble and give off gas. A little gurgling and “purring” is normal.
Can lead acid batteries explode?
Yes – a lead battery can explode due to either or a combination of the following reasons: The battery can explode if it is subject to an overcharge i.e. charged continuously though it is fully charged.
Is it OK to leave a battery charger on overnight?
It is essential to read the instructions with the battery charger to determine whether it is safe to leave it on overnight. However, it is generally recommended not to leave a battery charger on without care for more than eight hours, as this can cause overheating, damage to the unit, or even fire.
How much water should I put in 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.
What happens if battery water is low?
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.
What fluid do you put in batteries?
Battery fluid, a mixture of sulfuric acid and distilled water (called electrolyte), creates the electricity that makes a modern battery work so efficiently. Depending on the type of battery in your vehicle, battery fluid can evaporate and over time will need to be topped off as part of regular battery care.
Can you mix distilled water with battery acid?
When the battery electrolyte runs low, you should top up the fluid with distilled water. The diminishing level is due to gassing and heat, which reduces the acid’s water content. In this essence, adding water boosts the electrolyte level.
When should you replace battery acid?
Under normal circumstances, the sulfuric acid content in battery electrolyte never changes. It’s either present in the water solution as an electrolyte, or absorbed into the lead plates. In batteries that aren’t sealed, it is necessary to add water from time to time.
