How to Add Water to a Car Batteryby Contributor
Most vehicles have what is known as a maintenance-free car battery, which is permanently sealed and never needs water. If you do not have a maintenance-free battery, then you regularly must fill it with water.
Turn the car engine off. Open the hood of the car and locate the battery. Remove the vent caps from the battery. Clean the battery surface top before opening the inspection caps to avoid getting dirt and debris into the car battery.
Check the water level in each cell of the battery. Use only distilled water when filling a car battery. Using anything other then distilled water will cause permanent failure of your battery.
Add water to the battery to bring the level to just below the bottom of the cell inspection hole. Do not over fill the water level. This can cause the acid water mixture to leak. Flush any spilled acid water mixture with fresh water. Put the vent caps back onto the battery.
- Add water to your car battery more frequently in the summer months; water has evaporates quicker in warm weather.
- No smoking. Extinguish all open flames. Batteries emit hydrogen, an explosive, when charged.
- Do not let your battery water level get low, or allow the battery to run out of water. This can destroy the battery's cells.
