When I looked into this there were two models Red Top and Yellow Top.  The
red is normal, the yellow is deep cycle.  The battery had to be mounted on
its side in order to fit, either that or you had to cut the top posts off,
which may or may not void your warrranty.  Deep cycle is better of course.
