Question 4765
When a battery needs fluid, what fluid should be added?
- Distilled water.
- Water and antifreeze.
- Water and oil.
Show answer and explanation
Correct answer: Distilled water.
In a battery with removable caps, the fluid in the cells is acid mixed with distilled water. The water evaporates with use, so top it up with distilled water only. Never add acid, oil, or antifreeze. In the image, there is a bottle of distilled water next to the battery.
