Refill battery acid

[Miss Jamey Lynn]

Question if I drain the battery acid out of my rolls batteries and refill them with new battery acid sulfuric acid would that not theoretically create new batteries

No it just replaces the electrolyte. The plates have formed lead sulfate (PbSO
4) as the dissolved acid is depleted. It is a chemical reaction that does not fully return to its pre discharge state.

As Scott said, the lead sulfate crystallizes on the plates, so no use performing the very dangerous acid exchange. If you’re trying to refresh the battery, and it will take a regular charge, put an equalizing charge on it for “x” hours (Rolls probably has a recommendation for “x”). If it hasn’t sat too long, the equalize charge will bring it at least part way back. I could be wrong, but I think maybe Rolls recommends equalizing every 6 months. Provide plenty of ventilation when equalizing - it generates lots of hydrogen gas. If you can’t get a regular charge on it, don’t try to equalize it. What’s the history on the battery?

Buy new batteries. Very dangerous task you’re planning.
