What do you top car batteries up with?

Never top up with tap water, which contains minerals which may damage the battery. Use distilled or otherwise purified water, or a proprietary topping-up fluid. Avoid over-filling, which causes the electrolyte to leak out through the cell-cap vents as the battery is charged.

What fluid is used to top up car battery?

Tap water contains impurities such as minerals which collect on the plates in the battery’s cells reducing its capacity and usable life. Professional auto mechanics and car battery manufacturers recommend using pure water such as deionized water or distilled water for filling car batteries.

Fill each cell of the battery to a level just covering the battery plates, and then go back and top off each cell equally. 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.

How much distilled water do I put in my 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.
