Slowww cranking...need battery recommendation

[Chris]

Went out to the garage to fire up the Z and it turned ever soooo slow, finally click...click...click...click. Okay time for a new battery. Any suggestion on brand? I don't care about the weight or cost, looking for something dependable.

Does brand really matter? What are others using? Any gel cells other than optima?

Hey Chris,

I use and love AC Delco and saw a lot of recommendations for it when researching mine. But I have also heard good things about Interstate with 700 CCA. You can't go wrong with Delco, but I think there are many other good batteries out there as long as you stay name brand. I stay away from any that requires cutting the top posts off as I experience when almost buying the Napa Gel. Optima is supposed to making a direct application battery for the C4 but I think they still have the cutoff post issue or other have found resolution to the interference with the cruise control but bending brackets, etc. I'm a direct fit person with correct application from manufacturer. From my own experience, I would not recommend Sears Die Hard though.

I've always had awesome experience with the Optima batteries. I've never killed one yet and I have a lot of stereo equipment in my Tahoe.

I like the yellow tops but if you aren't pushing huge subwoofers or amps the red top is probably more than adequate.

What sorta modification do you have to do to the optima?

[N8nSM]

I have a Die Hard in the ZR-1, the Optimas are in my Z28, Tahoe, IROC, and Silverado. The yellow top in my Z28 has been reloacted to the rear spare tire well. The 4th Gen Camaro's have a pretty decent sized area and BMR makes a bracket that bolts right in once you remove the spare tire.

All the others the Optima fits right in the stock location with out any problem. I was going to buy an Optima for the ZR-1 as well but I was able to score the Die Hard pretty cheap and I didn't have to wait for it to be shipped.
