Neutralize Battery Acid

I have a couple cups of battery acid left over after buying a battery for my lawnmower.

What's the best way to neutralize this stuff so I can pour it down the toilet?

Seems to me I used baking soda years ago but that made quite a bubbly mess.

I pour it on weeds in my gravel yard...must be limestone cause it sure does bubble!

A big box of baking soda would probably work...but why not check at a battery or repair shop?

Why not just store it safely, in case you need some more later.

I agree with both Vic and Edward I wouldn't pour it down the commode

It's sulphuric acid, and it will bubble when it touches something organic, or steel for that matter. Pouring it down the toilet would be a no no. Even if it cost you a couple of bucks, take it to Wal Mart or some other auto parts place and let them recycle it.

I don't know why but they say to never use it to top off a battery, only add water so I'm not sure what you could use it for.

After reading this:

Concentrated sulfuric acid is frequently the major ingredient in acidic drain cleaners which are used to remove grease, hair, tissue paper, etc.

So, each time I flushed the can I'd squirt a tablespoon or so in till it was gone.
