  • First, DO NOT have the engine running when adding water to a battery. Chances are that the alternator is charging it and a charging battery produces hydrogen gasses. If the battery has caps on the top of it that can be removed, remove carefully. If it does not have caps, then it is a sealed battery and water cannot be added. When you add water, only fill it to where it just touches the bottom of the fill tube. Some auto part stores do have battery acid that can be purchased in small quantities. If you can find it, that is the best to use, just please handle it carefully wearing the proper personal protection. If you do use water, use ONLY distilled water. Distilled water does not contain dissolved solids like bottled or tap water. If you do use bottled or tap water, the dissolved solids can short out a cell, resulting in a dead cell, thus, replacement of the battery will be needed. Proof that distilled water works? here it is, I had a lawn mower battery from Wal Mart last me 7 years. When it needed water, I only used distilled water. It is on its second battery now for 5 years. Never had to put a charge on them.

  • Please do not turn the engine on. That will create a dangerous situation, if not from the sulphuric acid, there is a danger from the fan running. If your hand accidentally comes into contact with the fan, you will get seriously hurt. If your battery has separate cells, each cell will have what looks like an indented plus sign (+) on each cap. Or, you may have a battery that has two rectangular caps on it. Each of these caps covers several cells on each side of the battery. These are the batteries that you can check the fluid for. But if you have a battery that is maintenance-free, there are no caps on the top, and you can’t check the fluid in it. If you have one that has caps, you will need a large flathead screwdriver to open each cell. It your battery has two large caps, use a flathead screwdriver to pry open each cap from the bottom of the cap, and gently pull it off the battery. Be sure to cover the area around the battery with an old rag or towel you don’t need any more, to protect the area around the battery from sulphuric acid spilling from the caps and ruining the metal/paint. Put the caps somewhere on a a flat area, with the top side down, as the acid will drip if the top side is up. When you look inside each cell, the fluid should be completely covering the plates inside the battery. The level should be up to where it will look like an “X”. If you see the fluid is low, use a funnel and slowly pour DISTILLED WATER into that cell until it reaches the point where it looks like an “X” inside the cell. Be sure to put the caps back on the battery securely when you’re finished.Do not overfill the cells. If they’re overfilled, sulphuric acid with come out of the small vent holes on the top of the caps and damage the area around the battery when you’re driving.

  • Not all battery can have water added. In fact many new battery, they are sealed.

    If you do add battery, make sure you add only distilled water. At auto parts store, they have battery fluid specifically design for batteries.

    As for engine on or off. I would have it off. That the way it is done at the factory.

    Good Luck.

  • if there are battery caps on your battery take them off and fill the holes up with distilled water just until the battery plates are covered, it’s best if the car is turned off when you do this.

  • Car can be on or off. Remove caps, fill with distilled water to indicator (usually bottom of fill tube)

  • David C is right on, car OFF use distilled water only.

  • no problem if the car motor is idling or not, but i prefare to start thr motor in case in needes much water and do a drive or rechargeit again
