And yes, I already replaced it.

I had the alternator tested and it's fine. My car doesn't have an old-fashioned regulator (so I've been told). It's a 1994 Mercury Sable SRS.

In all my years as an auto tech the smell you discribe is caused by hydrogen sulphide coming off a dead cell in the battery that is gassing when under load. Excessive charge rates wiil only make hydrogen and it won't smell. I would strongly suggest that your new battery is faulty. Jules, auto tech and lecturer. Australia.

if it's giving off a foul odor still, the only thing would be the battery is being overcharged.
You need to verify that the output voltage on the alternator is no more than 14.3 volts. 13.5 is average.
If you have more than 14.3 volts, your alternator is overcharging the battery and boiling the electrolyte (acid).
When testing the alternator, rev the engine up to 2000 rpm as well.
What's at fault would be the regulator, which keeps the voltage at a constant 13 volts and prevents the battery from being overcharged.

Check to make sure all your cables are clean and that the ground to body is also clean. If your old battery was corroded it may have damaged the cables which will in turn cause a smell and kill the new battery.
It also could be your alternator is over charging the battery and boiling the water out of it.

I agree with Eric, and add one warning:
If your battery is giving off that unmistakable rotten-egg smell, and is hot: DO NOT TOUCH IT until it has cooled down.
A hot, gassing battery is incredibly volatile, and can explode easily, spewing caustic acid in all directions.
Have your vehicle's charging system inspected by a qualified professional.
P.S.: If you happen to get battery acid on your skin, or(God forbid) in your eyes, flush with cool water for 15 minutes and seek medical attention.
Always wear eye protection when working with vehicles, especially around batteries.

You could have a problem with your alternator/charging system. If the battery is being over-charged it will emit some pretty bad smelling gases. If you just put in a new battery yourself and didn't have the electrical checked, you probably should do so.

It's not getting brushed enough.
