Should You Hear Liquid In A Car Battery. ChrisTenone August 12 2018 605pm 5. You might hear a carbonated liquid sound every now and then as it tests the state of charge of the battery during the charging process but I have yet to experience actual rolling-boil bubbling sounds when using it.
Determining the moment the electrolyte begins to boil while the car is moving is quite problematic but when charging from the charger you can easily understand when the electrolyte begins to boil. The liquid should be above the level of the plates. Check the car battery water level indicator on a regular basis.
Make sure that you dont get in contact with it or touch it.
After normal use a battery should not leak. If not add distilled water. What you are hearing is bubbles of sulfur dioxide churning around with the liquid thionyl chloride. Use only distilled water when filling a car battery.
