As a matter of fact I have, and do.
I work with conc.acids, hydrochloric and sulfuric. Part of my job.
I did not say that battery acid is concentrated, I disagreed with your description that it is "pretty dilute".
Do the numbers:
Concentrated sulfuric acid, H2SO4, (the stuff that comes in the bottle from the chem supply house) is 96.0 % (wt/wt) pure and has a density of 1.84 g/mL Conc sulfuric is 18 M (calculated ph is -1.3!) Ka is 1 X 10e-2
Battery acid is generally 3 M H2SO4.
So take your conc sulfuric and dilute it one part in six with water you will have battery acid. roll up your sleeves and put your un-gloved right hand in that solution, then tell me if you think its "pretty dilute" or not. no don't do that ;)
