I'm not finding many options for better or bigger batteries for my 2014 GT. My factory battery is starting to get slow to start if it sits for a couple days.. really slow. I cleared away some corrosion that keeps returning even with terminal spray being applied. The only battery I found so far that looks decent is the Odyssey 1200MJT but it's not really any larger. It looks like there is room in the battery tray for a little more battery width. What other options are there?
