i was being exceptionally lazy when i posted that so I did some looking and the battery I purchased 3 yrs ago is no longer available. Its now the

Everstart MAXX-H8
CCA 760
$95 cost
$10 core
3 yr free replacement
has a vent tube

supposedly its the exact same dimensions as its predecessor (the one i own) so i measured mine.

13 7/8" long
7" wide
? height (its flush with the battery compartment.. sorry, didn't feel like pulling the battery all the way out)

like i said before.. cheap battery walmart sells.. fits perfect. No complaints here. /shrug
