Just thought I'd post this in case anyone is in the market for a really nice battery. A couple days ago I went out to the garage to take the truck out for a while and it wouldn't start. It had an Optima yellow top that was less than a year old and I always use a maintainer when it's not going to be driven for a while. I pulled the bigger charger out of my toolbox and hooked it up, reading on the charger immediately shot up to 16.8v, ouch! Charger then attempted to go into desulfate mode, and promptly shut off giving me a bad battery message. Long story short I run a pretty substantial stereo system so I wasn't just going to go buy a cheapie. Found out that a local battery store was a dealer for Odyssey batteries so I went to check them out online. On paper, these things are beasts compared to the Optima. Tons more CCA, and a little more reserve. $270 later I'm out the door and headed home to install my fancy new battery. All I can say after the install is WOW. My alternator is an Ohio Generator, don't remember the exact amperage but it's slightly higher output than stock, not enough to really keep up though. As far as I could remember I have always had some voltage drop at full volume, even when my Optima was brand new. Not the case with the Odyssey. After letting it charge up I went out and tested the stereo, no drop AT ALL. 14v on the gauge even on the heaviest of bass hits. I am extremely happy with it. The price tag is a little high but they have a 5 year free replacement warranty, and they're made in Warrensburg Missouri by Enersys. Only after this ordeal did I realize that Optima has sold to Johnson Controls and are now made in Mexico. If you're looking for a nice battery I can't say enough good things about Odyssey. Can't comment on longevity yet but if the warranty is any indication I'd say I'll have this thing for a while.
