The AC Delco Silver 30 month battery with 590 CCA with 2 caps on top of battery which is the factory replacement

or optional

AC Delco Gold 42 month battery with 650 CCA that is a completely sealed battery?lurk:

There is a $56.00 difference between the two batteries.

Gary7

I'd go for the Gold.

LS WON

Why? Is it because of the higher 650 CCA and 1 year longer warranty?

I was told I would not notice any difference in the operation of the Corvette between these two batteries?

EVRose

You need a new battery? NO WAY!!! Yours is only 11 years old!

HOXXOH

Yeah, but he just now tried starting the car for the first time in 6 years and got nothing.

If I had his luck, I'd buy the cheap one and expect it to outlast me.

I am no expert, but the more expensive sealed battery is most likely Absorbent Glass Mat (AGM) which is newer and better technology. Couple advantages to a corvette owner like me, who must store his car over a long cold winter season are: AGM hold a charge in cold weather better, with less recharge time needed to "float" back to a full charge.
Reduced need for charging equate to less "sulfation", which is what eventually leads to battery failure. These type batteries have other advantages, as well, thus the higher initial purchase price. If you live in a warm climate, not subject to seasonal car storage, probably not worth the extra money.

No it starts but it's 12+ years old. I will get it load tested.

HOXXOH

That load test will probably kill it. Kinda like forcing a 90 year old guy to run a 4-minute mile.

Or a 56 year old guy (me) to run a 4-minute mile.

If I ever had a battery that lasted 12 years (especially an AC Delco), I would "pull the plug" on it, bury it in my back yard, and erect a marble headstone in its memory!

2k Cobra

That is a record in my book! I would call Guinness..

LS WON

I am still driving it too. I wonder if they load test it (or will dealer charge me for that?) or is there another way I can test the battery to see how bad it is or if it really is going bad? Just for the record.

Or go to AutoZone store for a free test?

And then charge admission to see the gravesite.
