I’ve had my odyssey for probably 9 years. It was on my r100s, which has been sitting for nearly a decade, I was busy raising my son, and it sat on the shelf for at least 7 years. Surprisingly it was able to hold enough juice to pass tests and run my K75Rt, but it was time to get a new battery as the ABS didn’t like the old battery.
Just an FYI, I was able to get a new odyssey from FCPEURO for $147 shipped, which was around $40 cheaper than I could find locally.
