East Penn vs Johnson Control (Clarios) H8 / Group 49 AGM?

[f355spider]

What kind of life did you get out of the Diehard labeled Odyssey batteries that you have owned? I've considered buying an Odyssey, when buying a battery. I've heard accounts of getting very long service (8-10 years and longer) out of them. And I've also seen others state that they got no longer life out of their Odyssey battery, than they have out of any other auto battery, AGM or flooded.

Sorry, I don't have long term data, as I sold the car after about 3.5 years with the Odyssey battery installed. But it was in my former F355 spider that was only driven in fair weather, and I rarely used a battery tender on it.
