Your body automatically balances the pH of your blood. If it did not, you would not be alive to have written your question.
Their blood pH level(Acidity) is obviously lower than ours. (The lower the pH level the more acidic a substance is-The higher the pH the less acidic a substance is) So considering battery acid has a pH of .5 and can burn through certain metals and the aliens blood seem to burn through many things I'd estimate the aliens have a blood pH level of about -5 through -10.
