I know this is an old topic !
FYI:
After getting involved in a friends electrical/starting problems I added water to a repo Autolite battery. There are at least two repo Autolite battery builders, Vintage and New Castle (Turbo Start )now (Axion). Vintage has a battery within the battery case (Do Not Add Water) (do not use a jump pac) ,Turbo Start builds a lead calcium battery with a repo Autolite case. After turning the battery over to look for trade marks I found Axion & Turbo Start on the bottom and called them. The caps were glued on from the factory but someone had loosened them so I added water. The cells looked like plates but were white ( actually a matt material) any how they told me to just dump out the excess water so that just the white matt is visible and I was good to go. Vintage told me (thinking it was theirs) that I have destroyed their battery, do not use.
I hope this may help someone after today.
