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 battery vent tube for?

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.

Do AGM batteries need a vent tube?

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.

Do sealed lead acid batteries need to be vented?

SLAB, sealed lead acid battery, by definition is sealed. Hence no venting is required.

Why do you need to vent a battery?

For flooded, lead-acid, and AGM batteries, proper ventilation prevents the buildup of hydrogen gas, keeping the air around your battery and your vehicle fresh, clean, and breathable. Ventilation also helps prevent battery damage and, more importantly, explosions.

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.

What are battery vents?

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. There are many different kinds of vented cell batteries, including: Air Depolarized Zinc with Mercury. Air Depolarized Zinc, Non-Toxic.

Are all AGM batteries vented?
