Getting ready for a long trip and was wondering how everyone's experience has been with 2018 3.0 Battery life.
My mileage is 29,000 or so. Just like to know about battery life expectancy.


Thanks,

Honest John

My 2018 has 61k miles on the original battery and no issues so far.

I have a 2018 also, low mileage at just 25,000 miles. I still have the factory battery but last year I experienced an issue. The battery wouldn't start the truck without a jump. I took it to a dealer and they pulled the battery and gave it a hour and a half charge. They then load tested it and it passed. It has been working fine ever since and I have no idea what happened.

36,000 on my 2018. Never a problem with the battery yet . Starts up no problem even on the coldest days.

Had mine replaced under warranty after 1.5 years of owning my 2019 XLT

Batteries are more sensitive to age than miles.
It seems that battery life for an OE lead-acid battery installed in most vehicles is about 4-5 years. AGMs last a bit longer. Since our diesels use more current to start when cold (with the preheating cycle), that life will probably be closer to 4 years.

If you plan to park it for more than a couple weeks, put a battery tender on it. Nothing is harder on a lead-acid battery than letting it get deeply discharged and then sit in a discharged state. That accelerates plate sulfation. Lead acid batteries need to keep their charge topped up for maximum life.

I’ll note that a car I own, which originally came with a Ford-branded Optima battery (spiral cell AGM design), lasted 15 years!

just go to your local autozone and have it tested . battery should be good for 4 yrs to 5 yrs but i would have it tested

Thanks for the info Dunrollin! I hope mine lasts a little while longer but I think i WILL TAKE IT IN AND HAVE A TEST MADE.

Has anyone looked into fitting a larger battery in their F-150? The 3.0L diesel in my Volkswagen runs an H9 battery; the F-150 uses an H8 battery. Both are AGM, same height, same width, same post orientation. The only difference is that the H9 is 41mm longer (and a whopping 31% heavier). It looks like there might be room to the front.... I live a couple hundred miles from the Arctic Circle, so battery performance ranks up there for me.

If you live that far north, you better invest in a battery blanket/heater, in addition to a block heater.

The more important question for you is what are the cold cranking amps. A bigger battery doesn’t necessarily increase CCA, although it usually provides more reserve capacity.

Has ford given us a option other than turning the stop/start off manually ? can it be unplugged with out any codes or problems ?

The small BMS plug on the positive battery terminal can be unplugged and that will stop it but the battery management system will be disabled as well or better yet there is an after market module that can easily be wired in to do it. I use the module.

the module is called the Autostop Eliminator and it runs about $100,
