Four years ago bought a set of Lucas reproduction batteries with AGM guts (read expensive). They fit nicely and worked just right under the original bakelite battery covers. I’ve kept a battery minder on them continuously (and it is the right battery tender for AGM batteries), but they are toast after four years. Not really wanting to do this again, but it’s a preservation class car and needs two batteries that fit into the existing wells and can be made to work with the bakelite covers.
Wondered what sorts of solutions folks have found?
