Duralast is a good battery. I've had good luck with them. Not sure who the "real" manufacturer of that battery is.
Yellow Top for 07+ Denali?

Ok I've heard of Johnson Controls. Don't know much about then other than they are pretty main stream.

Duralasts gold is a good battery. That's what I run in my 07 F150 and haven't had a problem with it. I leave my stereo running for quite a long time and when I go to turn it on it doesn't hesitate to start.

Batteries are another Veblen Good Serge...
Get the store brand with the highest numbers and you'll have the best battery you can get...yes, better than Optima because they don't even have batteries as powerful as, say Advance Auto Part's brand.
For example, the battery I got for my '92 K1500 that will have a winch someday:
$100, and I used a $30 off $100 coupon and got it for $70...
Specs: 800 CCA, 1000 CA.
$190 Opitima Yellow Top: 750 CCA, 870 CA.
The Optima claims to have a longer reserve capacity...of 5 minutes.
I have my radio in the truck hardwired to a switch on the dash, left it running one night (got home while talking on the phone with the radio turned down..doh!), didn't get back in the truck for 3 days. My subwoofer amp is also on the same switch, and when I unlocked my doors I immediately cussed myself...but the radio was still on, and the truck cranked right back up. Ha!
I had a red-top in my '05 F-150, hated it. Died on me after about 7 months and wouldn't take a charge, warrantied that bad boy out and got my refund.

So here's an interesting fact ...
I'm at the dealership getting routine service and I handed them the two new batteries ... one to swap and one to add.
The service manager couldn't figure out how to connect the second battery so he got on the phone with gm to find out what is required. Turns out that to do this after the truck has left the factory it would need retrofitting of a new engine harness.
Yikes, is it really that complicated to bridge two batteries?

Thanks Juan.
well for now the new Duralast Platinum is pumping out 15V on the dash display when the old battery was suck between the 9-14V numbers at about 12V ... could be because it's just charging tho.
The thing about these trucks is that they have a volt range programmed into the BCM ... I think they do it for fuel efficiency reason cause putting out more power than is needed obviously requires energy.
The service manager said no pulley, Big 3, or alternator upgrade would really change anything as the BCM would simply readjust the current ... he said that if I was dead set on putting out a constant 14V, he could look into BCM reprogram for me.

15V nice. a BCM reprogram sounds nice I hate that when I unlock my truck the interior lights are dim but once I turn them on there nice and bright.
