Fwiw ..
I just get a '48' which is a stock diesel vanagon battery with usually
about 600 CCA's ..

they fit and work just fine.

the ones I use are from Knecht's Au
to Parts and are outright replacement for 2 years I think..
which is very handy.
  some of my vans sit a lot ( now with  battery-maintainer solar charges
on many of them - not expensive from HF )
and when a battery  isn't too happy ..
I just charge it up ....take it down there..they test it on their pretty
smart battery tester and
give me a new one.
