Has anyone used Optima in their 6.0's and if so which ones and how did they fit. I think I need new batteries one had a red eye this morning the other a yellow, also thay are mismatched (since the truck was new) one is a 650 cca one is a 750 cca.

 

Yup, time for a new pair for you. I've got an 03 and haven't had to put new ones in mine yet...but it's just a matter of time. So, I'm interested to hear recommendations/suggestions from other diesel guys on what they're using for replacements.

One thing to remember when shopping for batteries is the fact that they are the heart of the electrical system. With that said, Shop for the best you can get. Look at CCA and reserve power. Get batteries with at least 750 cca and 150 min. of reserve and things will be ok. Remember you get what you pay for, especially when shopping for batteries. Good luck!

 

Mine are only 2 years old but are mismatched I think the right hand battery is carrying the left smaller one. My therory is that the dealer had a battery die on another vehicle and mine was the closest and changed them out.

 

Yep, I have a shop on long island and I see that all to often.

 

DO replace both at once.

 

we always put a set of BXT-65 850's motorcraft. never a 650!!! 750's were stock and cannot even get them through motorcraft-only 850's. I never tried and optima, not sure you really need to spend the extra $$ unless you run upside down or go off roading and need the extra vibration protection.

I was told there are really only 3 battery manufactors for cars and motorcycles but many labels and colors. Do not buy the Neverstarts from walfart, seen alot of those dead shortly after replacement.

 

it seems 3yrs is the max i can get out of a battery, and they always seem to go at the first cold snap

 

I can believe having problems with batteries at 2 years. I had an Oasis report done on my '04. It had both batteries replaced at 11,000 miles (which I would guestimate is 2 years).

After I bought my F350 a couple of months ago, I had Autozone check the batteries and they said it should be fine for winter. His advice for me was that if I ever have battery problems, plan to just change both out.

If you've got a winch or cold weather extremes, or just want premium batteries, here's the best direct replacement: www.odysseybatteries.com/battery/pc1700_65.htm


Big $$$ though...

 

Just bought 2 new 900 cca Kirklands from Costco 36 free replacement and 100 month warranty. I does crank faster than it ever did now. Decided against the optimas at $200 each. I think the kirklands are made by Interstate but not sure.

 

I have two of the 2150's from Odyssey in my boat. Love them. It's worth the 4 year free replacement.

 

I was just going to suggest costco. Didn't know they offered a 900 cca though.

 

I was planning on Optima red tops, $340 out the door locally for 2. I am into my 5th year on the originals, preventative maintenance is in order. Based on the previous post, I will look into the Odysseys.

 

The guy who started Odyssey, is the same guy who started Optima. Optima was sold to Interstate. After the no compete period, he started Odyssey. IMO, the Odyssey is a better battery with a better warranty.
