Which battery to get?
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.

Battery Choice
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.

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?
