I need a battery (again). Right now there is a group 91 in there. I have been researching batteries. It can make you head hurt. Same group number has significantly different CCA ratings among manufacturers, and slight dimension differences. Here is what I think I know at this point.
Sizes mostly from Interstate chart. CCA various vendors.

Group size (GS) 91 and 91/48 are between 550 and 700. - will fit 11 3/8 X 6 7/8 X 6 7/8
Group size (GS) H6/48 are between 730 and 770. - will fit 10 15/16 X 6 7/8 X 6 7/8
Group size (GS) H7/94R are between 765 and 850. - size around 12.4L x 6.8W X 7.7H

It appears that the H7 will fit, but it is taller. With the 91 mounted, it is using the second last threaded clamp position hole in the battery holder.

THE QUESTION - will the H7/94R make it into the holder? Knowing how annoying it is to slide a battery into the holder.

This is not the base question, but -anyone have any real technical reviews (e.g., life time) of the H7 from multiple manufacturers.
