I don't think battery acid it is a good thing to put in your marijuana plants doesn't care about what they smoke
It's just sulfuric acid and there is no problem using it. Though for PH down I use phosphoric acid. For PH up you can use pro-tekt which is pottasium silicate but very pricey or Potassium hydroxide, I use both.
