I got mine off the shelf at AutoZone. The vent is a small tube about 6 inches long that connects to the battery and vents out the back of the car.

My car sits for long periods so I wanted an AGM type battery for my ‘03. Here is the top of the line at O’Reilly https://www.oreillyauto.com/detail/...ford/thunderbird?q=battery+-+automotive&pos=1
It’s vented, you just connect the tube off your old battery when you install.

I had to replace mine and had to get it from autozone as they were the only place to stock it with the vent.

Why do we need to vent with today's sealed batteries? Inquiring mind wants to know.

That’s a fair question. The AGM battery that I bought is a sealed battery. They say that these don’t need to be vented and can be oriented in any direction, yet the one for the 2003 T-Bird has the vent nipple coming out of the top of the battery to attach the vent tube, so go figure.

Batteries produce Hydrogen gas and it is highly flammable. Remember the Hindenburg? The matting in the AGM batteries is there to absorb the gas. Sealed batteries should not typically need venting. However, under high charge conditions, there may be some release of hydrogen gas. Batteries in an engine compartment have some free air flow. The TBird's battery is in the trunk, a closed compartment. If you do have a vent tube on the battery it's recommended to vent it to the outside to prevent any build up of Hydrogen gas.

Thank you. That is good to know and makes perfect sense!
