Optima Yellow Top - Totally Disappointed!!
I put in a new yellow top in Nov 2014. [$224.99] My car is usually trapped in the insulated garage for 2-3 months every winter (Idaho, it snowed yesterday, melted today) So I couldn't drive the car yesterday, but today was fine. Typical November usage for me.
Anyway, I didn't put on a battery maintainer right away...and in three weeks the battery discharged. No big deal right? It is supposed to be a Deep Cycle battery (like for trolling motors and the like). So, I charged it up and then hooked up the trickle charger.
So fast forward 24 months and the POS battery won't hold a full charge for a week!
My plan is to check for parasitic drain on the car, remove the battery and have it tested (it is still under the prorated warranty) at Autoland where I bought it. I'll let you know what happens.
ARGH!!

Sound's normal. I don't think most C5's can go three weeks without being driven or put on a battery tender. If it's in the garage for more that a few days without being driven, then plug it in. Probably not the battery's fault.

mine will go down to about 11.7 in three weeks and will still start the car. (Delco)

Typical Optima battery. I've never had one last more than 2 years. Stopped buying them a long time ago.
Question - Why put a deep cycle battery in a car?

I like the yellow tops, I put one on my car about 3 and a half years ago and it's still going strong... if you are leaving the car dormant for months at a time it's probably a better idea to just totally disconnect the battery from the car

First off I think you bought the wrong yellowtop, this would have been a better choice.
The 120RC would have been a better choice over your 100RC.
If you don't want to invest in an Optima 1200 Digital charger you might want to try running a known good regular lead acid battery in series between a regular charger and the Optima. Regular chargers will put a charge on the Optima but usually will not hold and voltage drops off fast.
Their is some good info about how to help maintain the Optima battery and would probably dispel a lot of thinking that Optimas are not good batteries even if you have had a bad experience in the past. Should be able to google Optima Battery and locate info that might help in your situation.
I have a 6 year old Optima redtop that is still a good battery that I just took out of my FRC and put in my Impala which sits a lot too but maybe doesn't have as much constant draw as the Corvette. It is a 100 RC rated battery just fyi.

Parasitic drain seems to vary. I can leave mine 4 weeks or so and it starts right up - problem is that's with the Sears Platinum (8 years old) which is now no longer available, tho' the Odyssey battery is the same beast. Never had a charger on it, except when it was left about 6-7 weeks one time - hooked up the charger and after a few minutes switched it to boost charge and hit the starter. Up and running.

Yes from what I've been reading I don't think it matters much what battery you use, it's just a big drain sitting there, mine went in about 2 weeks with a new Interstate. I've wondered what it is in these cars that drains it so fast, factory security system maby? My 2014 Sonata has one but I've never let it sit more than a week, maby most new cars are this way and we just notice it more on cars like this we don't drive much. That's why I just got one of these new Lithium jumper boxes, might get one for the Sonata too.
