I'm not 100 percent sure on the case size. They're the standard 6v sea volt 225ah jobbers from west marine. Like everyone has said, I think they're probably toast. I was hoping to save 500 bucks but it's probably the safer bet to replace them all and call it a day. I'll post pics of the demasting when I get back to my home computer. The main port chain plate split at the seam, apparently due to poor forging when it was originally made. According to the metallurgy lab, it was an accident waiting to happen. Unfortunately there was no way to inspect this particular plate as it was sealed up inside the interior paneling with no access. Luckily nobody was injured and we were only about 35nm south of Marathon when it happened. 30K later thanks to BOATUS Insurance, she's ready to go again.
Thanks for the advice,
Lloyd
