Batteries are bad in my 07 f-350 just wondering what is the best replacement?

 

you will get many opinions on which brand but my opinion is go with the ones with at least 850 CCA and if you can go for 1000 cca y o ur truck and ficm will thank you

 

It is a financial decision really. You can get Walmart or AutoZone batteries w/ a good warranty. You will probably end up needing the warranty though (IMO).

I have recently called it quits w/ the Motorcraft batteries - they are on the higher price side and only seem to last for 2 years for me.

I went with the Die Hard Platinums. They are made like the Odyssey batteries, but cheaper. They are highly recommended, but they are still expensive. Time will tell if they are worth it or not.

 

I just bought set of Wal-Mart EverStart Maxx. So far so good. They were about $100 a piece.


Mark, you never said how much were the Die Hard Platinums, if you don' t mind sharing.

I put in a pair of Johnson Control batteries, private labeled, 900 CCA, for about $90 each. Seem to be about perfect so far.

I bought the one from Costco, $87.00 a piece, 1000 Amp, 850 cold crank. The warranty is 3 years and no problem with Costco, their warranty is very good. I replaced mine after two years because I let the lights on and they where not as good. One was OK but since they are in pair, they said they will change both.

 

$220 each.

 

I bought mine from oreillys,super start extreme 850 cca 3yr free replacemnt,8 yr pro rated.after my discount 100 each normally 135

 

Oops! 84 month/7 yr

 

Thanks Mark.

It seems these trucks are hard on batteries by nature. The OP is a 2007 and has bad batteries. I contribute this mostly to the glow plug circuit. It draws a lot of current during start up, when you factor in the starter. This really drains the batteries. Just as a comparison I have a 2001 half ton Silverado with the original battery.
I have been giving some thought about wiring the glow plug circuit to two isolated batteries. This would preserve the life of the truck batteries.

Then you'd have four batteries to maintain. Do yourself a favor and don't. JMHO.

 

short run times and alot of starting puts the toll on tha batteris , high draw on starts plus the glow plugs, you are better off to let it idle for short periods of time than shutting down and restarting. being that you are in cold weather area, highest cca or reserve you can get the better off you will be

 

Check sears online...
They frequently have $ off coupons.
I bought my platinums 2 months ago
for $174 ea. $40 coupon plus $50
Off $300 purchase.. iirc.
btw, huge difference in cold cranking speed
than my old tired batteries.
My ficm voltages were always good on old
batteries

 

The Sears Platinum seem to be the best. I cured a lot of electrical problems including low voltage from the alternator when I switched to them.

They are now about 5 yers old and still strong.

 

the glow plug circuit in my experience is not why the batteries fail.

the reason they only last a little while, is 'cause they are NOT properly
charged by the alternator, ever.

my brand new OEM alternator only put out 13.2 volts. that is NOT enough
to properly charge a battery, and the AGM design require 14.2 or above.

my DC power alternator puts out 14.8 volts, and enough current output that
it will charge the batteries with a cold engine where the glow plugs are on,
with a godzilla stereo running as well.

it will put out 200 amps stone cold at idle, at 14.8 volts. the cold
engine start load with glow plugs is about 175 amps. so it'll charge
the batteries to the proper voltage, no matter what.

charging to 13.2 is a float voltage, and will not charge a battery beyond
about 30% of capacity.

we have been getting mornings down in the 30's here... i'm gonna
run out to the van next cold morning with my iphone and fluke meter,
and make a video on what *actually* goes on when you crank cold.

voltages, current flow (and direction) and the sound the engine makes
when the ECM turns on the alternator output after about thirty seconds
of idling. then i'll turn on the stereo, and crank up some godzilla level
80's rock, so you can see both sound pressure level, and voltage and
current.... maybe we can make a sticky here, and put all the battery
drama to rest once and for all....

first point of failure in the 6.0 electrical system is the ALTERNATOR.
everything else is a cascade off of that.
