Replacing Batteries?

[Wert]

Bought my first Powerstroke a couple weeks back When I gave it the once over I noticed that the battery on the passenger side was noticably smaller then the driver side battery Is this normal? I wasnt too worried about it then last week I was Elk hunting all week and the truck had trouble starting with the temps below 50.

Is it ok to just replace one battery at a time or should I replace them both?

Is it an E series van?

In the trucks the batteries should both be the same size

Its an F350... So the hunt for a new battery begins, assuming the other is still good is it ok to just replace the one?

[SCstroker]

It depends on how old is the "other" battery. Best thing to do, replace BOTH. I run Napa Legends. Another buddy runs interstate.

Both batteries should be the same size and you should change out the batteries in pairs because if you have one old battery and one new one, the new one will be doing more work and will go bad sooner than if both batteries were equal.

Is there any truth to swapping the batteries around each year?

No. They're wired together.

There is always a lot of talk about batteries, but remember your truck came with Motor Craft and I'll bet they lasted 6-8 years. And thats what I got $116.00 each at Ford. 5 years no prorate replacement, then an additional 3 years prorate. Can't beat that warrantee.

i dont care for the motorcraft batterys, i run interstate megatron PLUS under the hood along with 6 BT20 batterys in the cab(for my stereo) but lets just say i've tested it and one BT20 can start my truck

Unless I'm mistaken, I think Motorcraft and Interstate are made by the same company along with Duralast and Diehard. (Johnson Controls Industries) I doubt you'll go wrong with any of these. Napa's are made by Exide which are a good choice as well.

Batteries are kind of like oil filters.. there are a hundred brands that are made by a couple companies.
