How do you know when your car battery needs water?
On most flooded battery, there will be a maximum and minimum battery water level indicator were marked on the side body of the battery. Some car batteries case are using solid color so its rather difficult to measure the water level from it's body. For this case, you should open the caps and see the battery water through the vents port.
If the battery water levels are touching the minimum level indicator, then you should adding battery water to the properly level (between the minimum and maximum). That's why we need to check the battery water level regularly.
What types of water to be use ?
To adding battery water, we need distilled water only. Distilled water can be purchased at most grocery stores. Distilled water isn't harmfull like acid liquid. It's just the same as usual water, but they have distilled

Fill the battery water smoothly then check the battery water level using the level indicator, or if the battery don't have, just see through the wall near the port when we fill the water. If there are enough water, then you will see the water touching the end of the wall inside the vents ports.
Do this for all available ports then make sure that the battery level is in the right level for each cell. Twist the caps vents to the right to close and clean all the spilled water.
