Question: Can I Add Water To My Battery?

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 much water should be in a 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.

How do you fill a car battery with water?

Use only distilled water to fill the cells. Distilled water can be purchased at most grocery stores. If the electrolyte levels in the cells are low (plates are exposed), fill each cell to just cover the plates. Then use a battery charger to recharge the battery, or just drive the car for a few days in normal service.

Can you add water to a dry battery?

A “dry” battery is a lead-acid battery without the acid so it can be shipped without the hazardous liquid, the correct electrolyte acid must be used t fill it if you want it to perform its function. … If by “dry” you mean it’s low on electrolyte, yes. But you are supposed to use distilled water.

What is the main cause of battery water loss?

Approximately 50% of premature car battery failures is caused by the loss of water for normal recharging charging due to the lack of maintenance, evaporation from high under hood heat, or overcharging. Positive grid growth and undercharging causing sulfation also cause premature failures.

How do I know if my 12 volt battery is bad?

If your battery is reading 0 volts, chances are the battery experienced a short circuit. If the battery cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell. If the battery is fully charged (according to the battery charger) but the voltage is 12.5 or less, the battery is sulfated.

How do I know if my car 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.

How do you revive a dry battery?

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.

How often do you need to add water to a battery?

Battery watering is pretty straightforward. A general rule is that you should check water levels and fill the cells approximately every 10 charges of the battery, at least for the first few years of the battery’s life. If you have a reconditioned battery, you may want to cut this interval to once every 5 charges.

What happens if you put water in a dry cell battery?

“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.” Once the water is added, replace the vent caps and make sure they are tightened.

What happens if battery cells run dry?

As water is consumed, the electrolyte concentration increases and the electrolyte level in the battery drops with the loss of water volume. Eventually it falls below the top of the electrodes exposing them to oxygen from the atmosphere and charging gasses.

At what voltage is a 12 volt battery considered dead?

Resting fully charged 12-volt batteries are around 12.8-12.9 volts, and flat dead ones are at 12.0 volts, so 12.4 volts on a resting battery means it’s about 50% charged.

What happens if battery water is low?

If the electrolyte level drops below the tops of the plates, irreparable damage may occur. Check your battery water level frequently. Over-watering – Excessive watering of a battery results in additional dilution of the electrolyte, resulting in reduced battery performance.

What should a 12 volt battery read when fully charged?

about 12.9 voltsSo a 12volt battery will measure at about 12.9 volts when it’s fully charged and about 11.4 volts when it is fully discharged. That’s a total of 1.5 volts that represents the full range of charge on a 12volt battery.

When should you add water to battery?

While a battery should only be filled after it is completely charged, you should check the water level before charging. Before charging, make sure there is just enough water to cover any exposed plates. After charging, add enough water to bring the level to the bottom of the vent, about ¾ below the top of the cell.
