I had my step brother take my battery out to test it the other day. Test showed it was fine but when he put it back in he seemed baffled by the vent tubes. I explained the idea behind them and I think he hooked everything back correctly, but I'm not certain. Does anyone have a pic of a correctly installed battery so I can compare? Gracias.

Battery Replacement

Thanks for the diagrams. Mine does appear to be different. The square-shaped tubing doesn't appear to be held down at all. It is connected via that one-piece tube, however, it just kinda hangs out on top of the battery. Is it suppose to look secured? However, my battery is not an AC Delco. I think its an Everstart. Has a Wal-Mart sticker on it. Would that change the set up?

It isn't secured down at all. Once the two vent holes from the battery are hooked up to that tube, and the drain pipe is pushed into that rubber grommett in the car it pretty well holds itself in place.

Thanks guys. That makes me feel better. Last thing I wanna worry about is acidic fumes leaking into the cabin.

You no longer have the AC/DELCO battery, your good to go! (sorry folks, had to say it..)

As long as the vent tubes are attached to the vents in the battery as shown by the dashed lines in the second picture, you're all set. If your battery does not have those special vents where the tubes attached, you'll be venting gases into the passenger cabin.

I wonder if there is a noticable smell?

Not that you would notice. When a lead acid battery charges, it produces hydrogen gas which is explosive.

I want to make that second sentence into a plaque and mount it on the back of the front passenger seat. I'm sure my rear passengers would appreciate the warning...would certainly reinforce my no smoking policy!
