Fricking Viper battery went kaput today. So I went online to Odyssey to find what battery they recommended and while I was there I decided to look up the GT. They didn't have a match the last time I looked (4 months ago), but this time they showed a direct fit. The show a 25-PC1400T to be a direct fit. Just FYI for anyone wanting to change to an Odyssey battery.
