I've found references to Odyssey batteries, one poster suggested they're available as low as $120, but no website. They're $$$ at my local Batteries Plus, and I can't find them for sale online. Every online reference points to a battery place that doesn't carry them. Help? I've found Optima batteries online (http://www.1st-optima-batteries.com, http://batteriesareus.com) but one sells the 34R reversed post battery, the other sells the R800R reversed post battery. Are they the same? I thought the R800R was the old battery? Sam's used to sell the Champion version of the Optima, I'll be checking that out too.
