Anyone have dual batteries in your vehicle

You guys do realize you are responding to a 5 year old thread right? I would assume the OP has already made whatever changes he planned on a long time ago.

I don't have dual batteries in my Accord, but I DO have a very oversized deep-discharge battery, one that in fact ever so slightly bulges the hood- but which I consider to be very good backup over the regular sized Accord battery in below zero cold start situations and general emergencies that might require the emergency flashers or other lights, and/or the radio, to stay on for an extended period.
