I have a couple of Yuasa and Power Sonic conventional lead-acid bike batteries that I recently purchased for a very good bargain price from a seller. They are new and never used. But unfortunately, the seller did not have the battery acid packs in his possession. So, I have to end up preparing that myself.
I know that I'll need to prepare a 36-38% concentrated sulfuric acid solution (this is what manufacturers usually use) using my concentrated acid which is a 95-98% ACS reagent sulfuric acid.
Now I know that they usually use distilled water to prepare them. But I was thinking if it's possible to use ultrapure de-ionized water instead.
