Question about batteries

Through testing I found my driver side battery needs attention. The po just replaced pass side batt before I purchased truck with a Motorcraft (850 cca). Why he didn’t do both at the same time I don’t know. But driver side doesn’t look very old, it’s a Motorcraft 850.. Question is, do I just replace it with the same Motorcraft battery or ? My buddy is an Optima dealer, so I can get those cheaper, I think. It seems like I read somewhere, it is recommended to replace pass side with an Optima yellow top?

Wow! I figured there would be a hundred different opinions on batteries. Bottom line, I was just wondering if I should go with a regular replacement or an Optima.

Well, I'll bite: General opinion is to replace both batteries at the same time with two of the same type and strength - a stronger battery paired with a weaker one will have the strong one always "charging" the weaker one, which weakens it. For the 6.0, the stronger the better... I'm not a fan of Optimas at all - there are better batteries out there for your truck. If you stick with the Motorcrafts buy TWO... And make sure your charging system is up to the task as well. IMO a 140A alt is minimum for our engine...

Thanks, I always heard, buy two at the same time for reasons mentioned above. I’ll keep researching.

Just my .02 I would buy a pair of either the Odyssey 65-PC1750T or the Northstar NSB-AGM65 batteries. Good luck, Russ
