What is the battery vent tube?
A battery vent tube is attached to the battery so it can expel those gases out into the open air away from the car. This means the chemicals inside the battery have gone into melt down. When this happens they sometimes create gas. The metal case of the battery has a hole, or safety vent on it.
Why does my battery have a hose on it?
Those clear hoses aren’t for adding water — they’re to vent excess pressure from the batteries in case of overcharging. This means that yes, they do contain liquid electrolyte, but they should never need to have water added during their normal service life. The batteries are not necessarily completely sealed either.

Prolonged inhalation may be harmful. Ingestion: May cause severe irritation of mouth, throat, esophagus, and stomach.
Why the vent plug is kept open during charging of a battery?
The purpose of the vent caps is to allow for the escape of gases formed, hydrogen and oxygen, when the battery is charging. During normal operation, water is lost due to evaporation.
Is the battery vent tube in the trunk?
Yeah, if it’s in the engine bay, it’ll be exposed to the open air and will be just fine. Those tubes are for cars like Miatas that house their batteries in a more air-tight part of the car like the trunk.
Why does the Volvo battery have vent tube?
Your Volvo battery has a vent tube to vent the hydrogen gas that will build up in all automotive lead-acid batteries. This is to prevent the possibility of an explosion. Remember, ALL lead-acid automotive batteries vent hydrogen gas, and hydrogen gas is very explosive.
