Is battery vent tube necessary?

Is battery vent tube necessary?

Sealed batteries do not need to be vented. Although most of the normal gasses (oxygen and hydrogen) produced in an SVR battery will be recombined and not escape, oxygen and hydrogen will escape from the battery in an overcharged condition (which is typical with any battery type).

What is the purpose of a vent tube on a battery?

These vent ports allow the gas that is produced in the battery to escape. On applications with a single vent tube, the opposing vent opening on the battery cover must be plugged using the vent plug. Instructions for using the vent plug are included on the battery positive post cover.

Where does car battery vent tube go?

Do I need to vent a car battery when charging?

Always use extreme caution when charging a battery. All lead acid batteries contain sulfuric acid which can cause severe burns and can generate explosive gases. Even a maintenance free battery has vents to relieve the internal gases that build up inside the battery. Always charge a battery in a well ventilated area.

What happens when a battery vents?

Heat is generated in the battery during charged/discharged cycles which will cause the solution to expand and contract. The vents allow for this to happen without damaging the external case of the battery. The vents also allow for the battery to be serviced with distilled water and/or sulfuric acid.

Do maintenance free batteries need venting?

The answer is yes, they still need to be vented. This is because of the fact that AGM batteries are a form of valve-regulated lead acid battery. They’re “maintenance-free” in the sense that they don’t need water to compensate for hydrogen gas produced during the charging process.

What happens if you don’t vent car battery?

You have a major fire hazard or even an explosion in your boot, as while lead acid batteries are being “used” they release toxic and flammable gasses. Also the gasses could/will leak into the cabin .. if that doesn’t kill you, then you’d prolly lose a damn few brain cells.

Why are some batteries vented?

A vented cell battery uses a pressure release valve to allow the gases produced during its normal operation to vent into the atmosphere to avoid rupture of the cell case.

How much ventilation does a battery need?

Can you put a vent tube on a Prius?

The actual connector is a bit too small for the vent hole on the battery but if you put a small piece of the provided tubing on the battery end of the connector it fits very snuggly. It is then very easy to connect to the installed tubing on the Prius – that fits perfectly!!

Is it bad to block the vent on a car battery?

As for the vents on the battery itself, as long as they aren’t blocked so nothing comes out, you’ll be fine if it’s in the engine bay. Blocking them doesn’t let gas escape. I shouldn’t have to tell you why that’s bad.
