For a low water level, look for an exposed plate within the cell. In a normal cell, the fluid should cover the plate by ½-inch. As long as the water level isn’t ½-inch below the plate, you can usually refill it. Otherwise, you may have to replace the battery.
How do you know when your car battery needs water?
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.

What happens if you add too much water to a car battery?
Overwatering can cause the electrolytes to become diluted, which results in diminished battery performance levels. Pro tip: a normal fluid level is around ½ inch above the top of the plates or just below the bottom of the vent. If you check your fluid levels and the water level is sufficient, do not top it off.
How do you check the water level on a sealed battery?
Can dry battery be recharged?
The chemicals in the dry cells get used over time and the reaction is irreversible. Therefore, dry cells are non-rechargeable batteries.
What can I use instead of distilled water in 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.

If a battery is completely dead but has been revived by a jump start, there are ways to fully recharge your battery. The first is, as mentioned, by driving around. If that does not seem to work, however, car battery chargers can regenerate all of the charge into a battery.
What kills a car battery?

How do you revive a weak car battery?
Rejuvenate a battery by adding more acid
By filling up a wet cell lead-acid battery with the right amount of water, you can get it to work again even if it was unable to create a sustainable charge in the past. However, avoid adding acid unless the battery had some of its acid spilt out.
How many times can you run a car battery dead?
Jump-starting your car battery once is not a problem. However, if you have to jump-start your battery up to three times a week, it’s time to get a replacement, as it is probably damaged. Also, when jumping-start a car, avoid cranking it more than three times if the car refuses to start.
