I am replacing the batteries in my 2.0 and as of this time, am not looking to do a by-pass of the auxiliary battery or do a Genesis system (or similar). Based on a lot of discussion, I have decided to replace my batteries with Odyssey batteries. I have the main battery, but I am having trouble figuring out the comparable one for the auxiliary battery. Any help on figuring out which Odyssey battery would be greatly appreciated.

The auxiliary battery is an aux 14. I used Super Start batteries from O'Reilly's and have had zero issues. I have used their batteries for years. If one fails, you can return it to the store for warranty. The ir batteries are made by East Penn/Deka. NAPA's better batteries are made by the same company too.

Odyssey batteries are great, but getting one almost always means having to deal with shipping, which is even more of a problem if you need to return or warranty it.

Go for the Genesis system. You will appreciate it instead of worrying about the Aux replacement issues.

Make sure you verify that you even have an Aux Battery, as just today I spent the time going in from the top only to find no aux battery where I was expecting one. I guess that means I have eTorque? Nothing in all the paperwork I have said anything about an Aux battery, one way or the other.
