Delco Professional Battery

I have one in my 97 and the POS leakes as well. Except out of both the+and-
terminals. It was fine all winter but it can't stand the heat.Optima here I come.

That's bad news - when my original battery leaked, they replaced it with a Professional which (knock on wood) is still holding up - looks like an Optima in my future, too

Re: Delco Professional Battery (Sun Downer)
According to the latest Consumer Reports, The DURALAST GOLD (Autozone-$70) out-performed the Interstate ($96), Optima Red Top ($100+), AC Delco ($80) and Everstart (Walmart-$40) in that order.
Also, the free-replacement guarantee for Duralast is 36 months vs. 24 months for the Optima. The total warranty is 96 months (Duralast) and 72 (Optima)
For those in warmer climates, the Duralast number tested is 34DT-DGS.
For your location (North), the Duralast model # tested is 34DT-DGN.

Re: Delco Professional Battery (Sun Downer)
Based on Consumer Reports, I put a Duralast from AutoZone in the Stealth last year. No problems. That's what I'll put in the Vette when it's needed. [B

Re: Delco Professional Battery (ZAP)
Bought my last AC Delco battery several years ago. My wife's 94 Convertible Vette ate them faster than it eats opti-sparks (opti number 5 going in next week and we have never washed it). I buy just about any brand other than AC Delco and get the same 2-3 years here in Florida. I have gone to Champion, Walmart, and Autozone with the same results. All outlast and have never leaked like the Delco's. Just my personnal experiences.

Re: Delco Professional Battery (E-ticket)
Joel,
Just get it over with and buy an Optima. After all, it's what started the 94 in Atlanta (after you helped fix my loose screw Pertronix!). And it's what will go in ACAR when the present battery heads for that great recycling center in the sky! :crazy:

Re: Delco Professional Battery (Dave68)
Is it a sealed battery?
There's no way to tell by the test results, but I was under the impression that a sealed battery is not necessary in late-model Corvettes. The original battery in my recently sold 68 had a vent tube extending out through the battery compartment. However, the battery compartment was behind the driver. A sealed battery was the safe thing to have in that case, but our C5 battery is out of harms way.

Re: Delco Professional Battery (Evil-Twin)
I've been driving cars for 27 years and have yet to have a leaky battery, but then again, there was never a computer beneath any of my other cars. Uh-oh, maybe I'm due!

Hmmm, I'm still running my original Delco. No problems of any kind with it after 2 1/2 yrs. Uh, oh! I hope Mr. Murphy wasn't listening! :D

Re: Delco Professional Battery (Tx99FRC)
Tx99FRC,
Did you take off and reconnect the battery cables early in your cars life and/or keep the battery on a Battery Tender?
I'm postulating a therory.
Thanks,
Matt
