I've had an Odyssey battery in my RV-4 for close to 8 years. It seems like lately I had a few sluggish stars--as if the battery was left on for a while even though it was a quick fuel stop and the alternator was operating just fine. In searching to see what type of life folks were getting out of Odysseys I'm surprised to see so many people saying around 3 years. Am I only hearing about the bad? What are others getting out of their Odysseys?
