When I run my 2001 Accent I sometimes smell a funny odor upon parking it. I discovered it is sufuric acid fumes. The battery sometimes spews liquid from around the cell cover caps and it runs down the sides onto the battery platform. I sucked out some of the liquid to lower the level but it still does it. I checked the voltage when engine is running reved up and I get almost 14.3 volts at times. Is this excessie voltage? What is normal. I'm thinking the voltage is too high which may be causing the battery to boil over.

changing the battery is not going to cure the problem, more likely is that the alternator is faulty and is giving far too much charge

14.1 to 14.6VDc is good. your alternator doing is job.

You have probably a short cell inside your battery.

So the other cell get more voltage that normal.

You should replace your battery now...

and neutralize the sulfuric acide with water and baking soda.

because the acide will attack the metal.

Good luck and let us know what you have done.
