I am now not so sure it's a 27DC-6. I don't have the van nearby so I
can't check. I remember that part number distinctly, but now I think
maybe my memory is playing tricks on me. Googling around, I see that
"27DC-6" is the part number for an Exide battery very commonly used in
solar and RV applications, and it's HUGE-- a group 27. The fact that
I've recently done a lot of research into solar RV battery charging
systems for a client at work leaves me with the sneaking suspicion
that I am conflating a part number from my research with the WalMart
battery in my van. I feel I must suspend my previous battery review
until I do a sanity check on the actual battery itself on Sunday. I
could swear I remember right, but it wouldn't be the first time this
has happened to me...
