So amiss the cold temperatures, my battery is biting the dust. It's a motorcraft one and they put it in the truck when i bought it in October 2010. Truck struggles to start if i let it sit for more than 2 days, and the temps here are ranging from 0-10 degrees F here, and have been for a month or so. The battery has a 100 month pro-rated replacement warranty, but I don't have receipt for it, nor do I feel like dealing with my local dealership.

So this weekend when I'm home from college I plan on getting it tested and replacing. The motorcraft one is 650 CCA, but I want something in the 750-800 CCA range.
What brand do you guys run? I was thinking:
NAPA Legend (father has used 4 of these in the past with success)
Optima Red top (very pricey)
Walmart Ever-start (Heard good reviews online)

 

I just replaced my Motorcraft 650 after it konked out in -35 / -45 with wind chill temps with a napa equivalent 850. Wow what a difference, instant crank and start. It's like my starter is on steroids!

 

I've always had very good luck with Autozones Duralast batteries. Used in just about every vehicle I've owned. And there reasonably priced.

 

Interstate mtp 65 , about 120 bucks. I believe its a free replacement if any problems in the first 4 yrs. Alot of members here run this too.

 

DieHard Platinum AGM Series 65, 930 CCA.

The battery is vibration-resistant and sports a military-grade construction, but weighs in at about 60 pounds.

I have had it for two years and it has been a great battery. Heat here in south-central Texas cooks my batteries usually within 48 months. This has a FREE replacement within the first 48 months.

I paid less than $200 for mine, so price has gone up.

 

Diehard gold is a great option also 850 CCA

 

all I know is my OPTIMA red top hasn't failed me yet.
