Check the electrolyte levels

Most car batteries have removable caps that allow you to check the electrolyte levels inside the battery. Make sure the battery is filled with distilled water to the appropriate level. If the level is low, add distilled water until it’s full. Be careful not to overfill the battery, as this can cause it to leak.

Turn off all electronic devices when the car is not in use
