I posted in another thread about how the battery seemed way smaller in 09. I serviced one again today and right on top it says 540 CCA. That seems a little small to me. I think every 08 and older I've seen has 800+. Is there an option for something bigger?

 

Doe's your truck have trouble starting? Reason being is we had some stupidly cold days here and it had no problem at all. Could be another issue and not your batt.

 

It's not had any problems starting that I know of (it's not my truck). I was just curious why Ford decided to downsize.

 

did it have the 4.6 2v in it?


that motor doesn't need alot CCA...it is the Mustang motor after all

 

The 5.4s have the 540cca too. Or at least mine does.

 

wow


that just seems so...inadequate. Wonder what the reasoning is behind that one?

 

I dont understand why it's ment to be larger? I could understand if the trucks had trouble starting in cold climates but 500+CCA shouldnt have any problem starting any 5.4 in 99.9% of climates.

 

my first 08 and my second one BOTH came with the 540cca. My first one died with no warning, and got replaced with the biggest one that would fit in the box. My second 08 got the battery replaced the first Saturday I had her. That 540 isn't enough for a well equipped truck.

 

i took that battery out and put the optima red top in out of my 05 that got wrecked.

 

Why would you replace a perfectly good battery? Why not use it for it's useful life then replace it with your choice?

 

personal preference. just knowing that you have the power to start/run whatever you need in your truck without straining the alternator and battery.

 

So is it going to be better for my engine if i put a bigger batt in?

 

well it wont hurt it. it really just depend on what your planning to do, running aux lights, winches, radio system, etc... stuff like that, then yeah i would go with a higher output battery. for stock, it would be fine.

 

No. If your battery is in good operating condition, there is no reason to replace it. High duty conditions may shorten the life expectancy of the battery but replacing it prematurely offers no benefit other than lightening your wallet. Extreme cold, running lots of off-road lights frequently, or running high power audio amplifiers are some of the more common high duty conditions that come to mind.

 

ohhhh good good. Would rather spend the money somewhere else.
