I bought the right battery for my 68, The Autolite sta-ful. but when I drive the car for 20-30 minutes and open the hood there is acid on the top of the battery,looks like it is coming out of the vents in the caps. I didn't overfill it when I put the acid in, made sure of that. Could the electronic voltage reg. be allowing to much voltage for the old style battery? Other than the reg. it is bone stock and original. Even the alt. is the original. I am afraid this is going to splash on the paint and eat it off the car, so I need some help pretty fast.
