There are only 3 battery manufacturers total, so most of them are all the same thing. Just go for the largest CCA one's you can find. I got mine from Napa, got the 880CCA units, amazing how much easier the motor spins over now.

 

what didi you pay for them???? Did they come with a decent warranty?

 

I went with the Motorcraft 850CCA batteries. I believe it's a 36 month straight replacement warranty, pro-rated after that to 84 months. They were $260 for the pair and the dealer installed them for no charge.

 

Honestly I don't even know what they cost. At the time Wal-Mart actually had the cheapest batteries around, I just hate wal-mart with such a passion I was willing to pay whatever to get them somewhere else. Honestly wal-mart may be the best bet. I think they have a stupid long warranty and if you ever break down somewhere in the middle of the night, the chances of there being a 24 hr wal-mart around are pretty good. I know guys who bring them in a week before warranty runs out every year and just get new one's.

If memory serves, the batteries were like $80 a piece at wal-mart too. I believe the highest they had was 750cca and 850cca, depending on what you wanted. Go for the largest CCA you can get in that battery size.

 

Just put the new batteries in and still having a hard start. Heres a link the video.

6.0 F250 Long Crank to start - YouTube

 

I watched the video a few times. It doesn't sound like it is taking it that long to start to me.

Sounds like it turned about 2.5 seconds before it started?

 

That starts better than mine... Remember it's not a Lamborghini... I think it starts up just fine compared to mine and my buddies 2 6.0's

 

It sounded like it idled smooth once it fired right? Did the new batteries change the idle at all at least?

 

No once its sits and the oil cools down its rough idle until oil temp reaches 100-115 degrees. In the video the truck was warm thats why there was no rough idle. The dealership here wants $95 dollars to hook it up the the computer but i find that crazy.

 

Yeah they charge a flat rate of an hour for diagnostics. Someone near you has to be able to check it out... There is a pretty big powerstroke following in NC. Isn't Rudy's in NC too? Maybe call them up, I'm sure they could help you.
