I am ready for a new battery. The car sits several months in the winter without starting, but I have a battery tender. So which is right for me ? Thanks

Most folks will probably recommend the red-top. I'd say 99% of the cars I've seen at shows have the red. The only time I've heard folks using the yellow-top is if they had drastically upgraded some electronics that need "juice" while the car is off. The yellow-top is defined as a "deep-cycle" intended to support electronic components.
The "Red-top" should be just fine for you. I have a couple in service and have not had a problem with them. The "Yellow" is a deep cycle battery that might be good if you are an audio nut and have your radio/player on for long periods without the engine running. Keep using the Battery Tender!

My car sits in the garage from December to April. I don't do the road salt and pothole thang. I have had a hellish time with brand new batteries going bad on me... probably because: a) I was buying my batterys at BJ's and Sam's Club, b) my approach had been to recharge on an "as-needed" basis, and c) my parasitic current draw appears to be above what some folks say is normal. While I have changed my ways and now own battery maintainers for both the Vette and the Harley, I have ordered a Yellow Top because I never again want to deal with battery replacement in the Vette. I'm told that even if the Yellow Top is drawn down into the basement that the battery can be recharged without having done any permanent damage. That sounds awfully appealing to me right about now.
I never heard about an "Optima" battery until I came to Corvette Forum. What's the big deal about that brand?
I hope I get this straight: They are AGM spiral cell construction so no possibility of leakage (and resulting damage to C5's vital parts). Also should last longer and handle vibration better. To be honest, I also think folks like the high-tech way they look.
Dave, When I purchased my '98 last year, it had a duel post red top that was on it's last legs. I replaced it with the same type, and had no problems till this past spring startup. Seems the battery drain that has been mentioned before took it's toll and totally killed the battery. It wasn't shorted out totally, but had a very low resistance. The friendly Optima dealer had told me when I bought the first replacement that the battery should be fine without a battery minder over the winter, so with raised eyebrows I decided to listen to the young feller. Well, never again. With my NEXT new duel post redtop in hand, I dropped it in was was back cruising in no time. I'll NOT be forgetting the battery minder from now on. BTW, I use a duel post to power a 1200 watt stereo and have had no problems with dimming lights or loss of bump using the red top. (duel caps, 1F total help out there) But I don't power the stereo by itself for any length of time. All in all, the optima looks great, 3 year warrenty (no questions asked) and will NOT leak on sensitive parts! Worth a few bucks more.
One other point, Optima makes two Redtops, a group 75, and group 78, get the 78 (a little more cranking) costs a couple of bucks more, paid $103 at Pep Boys, they will price match with Costco, but you need to ASK for it!!
