Do the newer restoration batteries have AGM guts in them now? anyone buy one recently? Bought one several years back and it was a real turd...only lasted 2 seasons and it leaked. Swore I would never buy another one, but they look so cool and if they are better these days I am gunna get one. Any insight or recommendations is greatly appreciated. I believe I need the group 27 with red caps. (early build date, 1972 b body with a 400.)
