Tahoe 12v, CCA are worthless?

Tahoe 12v, CCA are worthless?
Selfish questions, since my battery is stock and dying...
So... The engine is started by the 300v battery applying power through the motors in the transmission, right?
So why should I care what the cold cranking amps are on the battery? I really should be looking for a battery with the highest reserve capacity that will fit in the space. I am talking about a deep cycle battery.
Anyone agree or disagree? Since all the 12v battery problems I see on here are due to the 12v loosing too much juice to keep the computers happy, it seems to me it is way more important to have more reserve capacity and not cranking amps.
I am sure the CCA and RC probably increase with each other to some degree...

I used a red top Optima for a replacement on the stock lead acid Delco in my Hybrid Tahoe. I'm at about 4 years on the Optima which is a miracle Here in Arizona. I believe the stock Delco lasted just over a year which is not unusual in the extreme heat here.
If the stock Delco wasn't sealed and water could be added as needed it would last much, much longer, I have non-sealed lead acid batteries in several motorcycles that are over 10 years old because I trickle charge them and add water as needed.
You could go with a yellow top Optima if you want a deep cycle battery or if your budget permits, I have found Braille batteries are the lightest and best quality battery I have used, but they can be pricey.

Although I use Braille Batteries in several of my vehicles, I used an Optima Red Top in the Tahoe, I didn't see the need and I find the Optima completely adequate for the Tahoe.
