Optima Battery.. DON'T BOTHER!
You are upset but the fault lies with your expectations. As far as comparing the truck to the Vette that is apples to oranges. The Vette is known to draw a slight current even when the vehicle is off, not the same as a simple truck! The reason people stress the battery tender on the red top is because of that constant current draw of a Vette and the tendancy of a red top to start failing if not kept charged...if you didn't intend to maintain your battery you should have bought the yellow top in the first place.
It is unfortunate that the dealer you decided to take it to doesn't have the authority to make warranty exchanges, better planning on your behalf would have been prudent.
Sorry but I get upset when people condemn a product that they fail to maintain. That is not the manufacturers fault. Good luck with the GM battery.




I might add, I take care of all my vehicles so I would not consider myself as a person you say condemns a product that I have no control over THEIR quality control...A battery Ive had less than 2 weeks and I get slammed with a comment that I don't maintain my car? Even a gold plated Optima shouldnt go DEAD in 2 weeks (driven every day).. Excuse me for taking offence for that comment but... WTF! This thread is just turning into a pissing war... Lets face it.. The Optima Red Top is just as crappy as their customer service as well as the way they deal with their warranty. If they actually insist on me returning the Yellow Top, I have been assured by Sams Club of a FULL refund. Its just a pain in the butt to have to haul it back to them because a product that should last more than a few weeks FAIL and the company that makes that product FAIL to honor their warranty.. Enough said!

Ever wonder how many Cadillac and Buick owners change their DELCO's to some other brand battery, not too many.
I personally think DELCO's are quite adequate for the Corvette and keep DELCO in my vette just to keep it stock like. Its the original factory installed battery installed in Jan of '04! (Nowadays I keep it on a Battery Tender.)
On the other hand, my experience with INTERSTATE batteries makes me believe they are the best of the best. I've used them in my other cars from time to time.
..rickko..


I'll be interested to see the reply to that letter.
The choice of battery is always a talking point here. To answer Rickko's question, the reason many of us bought Red Tops was because of the early leaking AC Delcos. This picture from a few years ago was typical of the problem

Even though those batteries are long gone, some who suffered are still understandably nervous. I left a large acid stain on the garage floor in Vegas from a "leaker" from my son's Camaro. Luckily it wasn't in the car. Out of interest, GM replaced those early leakers with AC Delco AGM batteries in 01. At that time, many had early failures, me included.
As for the ongoing debate, AGM batteries don't leak but they dont like being discharged either. The fact is this car has a drain on the battery even when idle. If you dont look after the battery and its left idle for a long time it will die, AGM or lead acid. It's just that lead acid batteries, generally, are easier to recharge.
Ultimately, if members understand what they have fitted they should never get caught out. If the car sits idle, fit a tender or disconnect the battery.

I just bought one for my C5 Coupe. It came with a 3 year FREE REPLACEMENT Warranty AND a 7 year pro-rated warranty.
800 CCA's (800 Cold Cranking Amps)

The Best of Corvette for Corvette Enthusiasts




i get annoyed when people say a company is crap because of everything that is written about it on a forum. if you go by that theory, why did you buy a vette? the forums are full of issues C5s have.
just be happy you got a yellow top. i wouldn't take it back because you bought it. so in your mind, optima took care of you and honored their warranty. if they didn't back up their own dealer, that's their problem, not yours.
This problem (the dealing with a red top in a C5) is something that started years ago when owners, afraid of the horror stories about acid leaks, made wrong assumptions and selected the wrong battery based solely on the acid leak possibility.
The red top is not and never was the right battery for the C5. The reserve capacity is not high enough, and the parasitic draw of the C5 makes the choice of a red top problematic at best.
Many have had success with the red top either by pure luck, or by jumping through unreasonable hoops to maintain them (yes, having to keep a car hooked up to a battery tender if its not going to be driven for a month is unreasonable). Now we do it (using a battery tender, I mean I even keep my Sears Die Hard Platinum on a tender) but that doesn't mean its reasonable.
We have parasitic draw that many other cars do not have. I'm not happy about that but in my opinion I'm willing to accept the parasitic draw issue for everything else I get out of my C5.
My understanding the problem has made me a lot less critical of battery performance. Ive learned what I have to do (keep it on a tender at home and if parking away from home for weeks at a time, disconnect the battery when parked). If I do this, I have zero problems, if I don't I have problems but it sure isn't the batteries fault.
I have a seven year old truck with the original battery, starts every time no matter how long left parked, I had a fifteen year old accord that sat on the driveway, never driven, for years (mom passed, never got around to getting rid of the car), it started every time, generic battery, no tender.
So rail away at the night if you must, but until you understand whats going on with this particular car, whats different about the C5 and how to avoid the inherent problems, you are going to have not only "battery" problems but very likely AH/TC, Colum Lock, headlight up/down and a host of other "battery related" problems.
You can use any battery you want in the C5. Your choice will dictate what type of maintenance measures you will have to do to avoid problems. Trust me on this . . .there is no battery that you can purchase, put in a C5 and leave it parked "indefinitely". If you put an anti-matter cold fusion 6437 with the dilithium upgrade . . .it will die in a C5....eventually. Resign yourself that some type of battery maintenance will be required on any C5 not driven daily or parked for long periods.
Personally, I drank the red top cool aid myself, after two of those over a few years (and a ton of reading) I came to the conclusion that I needed a battery with a reserve capacity of at least 120 that wouldn't be a problem to recharge and under no circumstances would leak...ever...at all.
For me, that choice wound up being a Sears Die Hard Platinum (P4 size, not the P3 size that Sears computer says a C5 needs. The P3 only has a reserve capacity of 90, you need 120).
A very good video to watch that explains many of the battery problems the C5 has is here http://vettetube.com/view_video.php?...25f49408d959ca
The guy speaking is a world class certified vette guy and knows the C5 in and out. The video is long but it does go over a lot of problems and its worth the time.
So what works for me is:
Sears Die Hard Platinum P4 size
On a CTek charger when its parked here at home
Battery disconnected if away from home parked on vacation for several weeks.
Your mileage may vary.
Good luck





As far as the 7 year Delco battery, I lost all faith in this one as I had it in my 3.5 year old DD and it died suddenly without any warning. I take it back to the GM dealer and the warranty was not in existence. It seems you get a 7 year warranty if you purchase a new battery but if it comes in your new car, it's only covered for 3 years. So, I took my business back to Sears for a Diehard Gold for the DD.

P.S. Jistari is right on with the info on the Red Top & the Sears Platinum Battery. However,
I have to differ with him on the absolute need for a battery tender on the Platinum.
I have never used one with my Platinum and have left the car sit for 3 weeks and the
car started first time and not even sure if the original plugs and wires are still on my
99 (I'm the 3rd owner). I do usually run my car once a week, year round, weather per-
mitting.

(knock on wood). Just to make the few of you out there happy, I went to the local auto parts store and BOUGHT A BATTERY TENDER! I bought the Battery tender Jr which connects to the battery without the clips, and I have the connection running to the front, "hidden" so I can just plug in, if I was to not drive my car for a few weeks during the winter. (happy now?). Ehh, it was only $35.99 so I didn't see it as a big deal since so many of you swear by them. I still feel it ridiculous that a $50k car and a $220 battery needs to be on a tender! 


I guess Ill see if this guy calls tomorrow still wanting his battery. Im only going to be a nice guy if it happens by Friday. After that, I feel I actually own it, even though I DO have a receipt for the warranty adjustment and the difference between the Red and Yellow Top Battery. I can only assume he is lurking on this site
as I type since he claimed to have read posts in the past. So, the saga continues. Tune in tomorrow for more updates! 

Once again I must say, SHAME ON YOU OPTIMA
My c5 isn't a daily driver, but does get driven 1 or 2 times a week in the summer and once every 2wks in the winter. Stored in a climate control garage in Jersey so i never really needed a battery tender but climate really does dictate the life expectancy of a battery. Anyone from florida commenting on a battery life doesn't have the same weight as someone up north, as expectanies are half as less due to extremes in both categories of heat/cold. A/C delco for me next time though.







I'll stick to my far less expensive conventional battery that has sat for more than a month and fires the car with no problems when I turn the key.
