One note on my reference, the MJ in the suffix is for the metal jacketed version, the T suffix by itself would be without metal jacket.

As Pops noted, I like the Odyssey as well, though I go with the 925 series just from a personal "security" point of view, and in the '32 '33 & '36 I didn't have the same space constraints. It has a nominal 50% higher rating across the board (100% in reserve capacity) in a package that's just slightly bigger. We've discussed this before, but might be worth mentioning again. Since these are a dry cell battery they can be mounted in any position. If you put the 925 on it's side it is only 2 inches thicker than the 680, so if you've got room in that direction, and you would like the higher electical capacity, that might be worth considering. As Pops has indicated, the 680 has worked well so far for him, so it's just a matter of space and personal preference.
