OK, what's it mean if my battery is "burping"?

My '02 has been missing quite a bit the past couple of days (worse when cold), and when I got back from work a minute ago I popped the hood to find that the battery was blowing bubbles (at a rate of about 3-5 per minute) out of one of the caps on the top. A small (nickel-sized) quantity of fluid was around the edge of the cap; I assume it's electrolyte.

What, if anything, does this mean? Could it be related to my miss? I had the battery and alternator checked this morning at a local AutoZone, and the guy said everything looked good. Battery's about 3 years old (no-name), alternator was rebuilt last fall, voltage regulator was a new (but not Bosch) unit 18 months ago.

I'm leaving for the first leg of a Texas trip tomorrow evening and need to know if I should try to find a new battery or voltage regulator over lunch tomorrow...

Well, at least as far as most of the miss was concerned. I called and found the local AutoZone had a voltage regulator in stock, so I drove over and got it. Not Bosch, but the old one wasn't either.

The majority of the nasty miss is now gone, and the car runs much smoother. Checking the battery after getting home, it's still outgassing a small amount (I can hear it "pop" very quietly but not see anything), but I forgot to wipe off the existing electrolyte so I don't know if any fluid is still coming out. Worst case scenario is that I'll need a new battery also, but I think the v.r. was on its way out.

I'll get a new Bosch one as soon as I return from the trip.

Thanks, Britt!

to the battery from the alternator. IF faulty, the obvious it can not restrict current enough causing the battery to boil of over restrict and not charge the battery enough causing the battery to go dead.
