Actually..... your understanding of battery chemistry is off the mark quite a bit. You DO NOT add acid to a battery...you only add distilled water. During the charge distage cycle water (H20) is released/vented off as a gas. The acid (Sulfuric btw ) remains behind. Adding addditional acid to the battery cells changes the ratio of water to acid and will in time render the battery useless.
There are many sites that will explain the chemistry and do's and don'ts of battery care etc. Addding acid is a MAJOR don't !!.
here's a typical site that will tell you more than you need to know without having to have a degree in chemistry.
Batteries

BTW... here's a quote from the section on battery dangers.

"Some outgassing is inevitable, a small amount, due to difficulties in getting the same voltage across all of the cells in a battery. Also watch the liquid levels in a battery. The non-sealed ones will evaporate. Replace the fluid with distilled water only! Never add more sulphuric acid, you will unbalance the battery."

Since you evidently didn't bother to read the original post, I'll include the relevant portion here:

Ever see the movie "Aliens"? Exactly what happened there when the acid hit the floor.

NOPE...Hubby added water...go back and read it yourself...the battery boiled and battery liquid (typically a 65/35% solution of acid and water) spilled out on the floor. Adding acid (HSO4) changes the balance in the cell.

Ok, so you agree that the battery lost "battery liquid" (your words), and you agree that it contains acid. Correct? After all, the acid ate through the OP's floor, so this is a stated fact.

And your contention is that just adding water is somehow going to magically recreate the acid that spilled out of the battery? That's simply nonsense.

What's wrong here is your inaccurate use of terminology. The liquid in a battery is not just acid. It's a solution of Sulfuric acid and water ; and I gather since you know what a hygrometer is and what it's used for you know that. That being the case you just can't tell someone to add acid (HSO4). What is sometimes roughly called battery acid ( and incorrectly I might add) is infact an acid/water solution. I know that, and you know that. But a lot of people don't know that. AND... I'm guessing that anyone who would over boil a battery to the point of eating a hole thru a concret floor dosen't know that either.

There is absolutely no inaccuracy of my terms. I called it acid, and that's exactly what it is. The definition of acid is anything with a pH less than 7. Battery acid is the industry standard term for it. Walk into any place that sells lead acid batteries, and they will know exactly what you're talking about. The term is even in the dictionary. See for yourself. battery acid - Definitions from Dictionary.com The fact that it's a particular dilution of sulphuric acid is of little relevance to the discussion and in no way negates anything I've said.

Look. First you claimed I was wrong in saying the battery needs to have acid put back in after losing it. Now you've apparently given up on that approach and are just quibbling over my usage of the term "acid". Why are you continuing to attack my posts such nonsense?

Wrong. The device used for testing the specific gravity of a battery is called a hydrometer. A "hygrometer" is a weather instrument used for detecting water vapor in the air. That's seems a rather ironic blunder coming from a person accusing somebody else of using "accurate terms".

Oops....I replied to Kdog before I read page 2 of the posts...I'm always in a hurry. At this point, I'm going to call the dealer and see what they suggest.
I've graduated Battery Acid 101. Thanks everyone.
