2011-2014 Ford 6.7L Powerstroke Batteries

Batteries on the 2011-2014 Ford 6.7L Powerstroke

Ford wired two Group 65 batteries in parallel on the diesel Super Duty, and together they crank a 16.2:1 compression V8. Common replacements are 750 CCA Group 65 batteries in flooded or AGM construction, and options run from about 650 to 950 CCA; 750 CCA is the common OE-equivalent rating. Each battery sits in its tray under a hold-down bracket that keeps it clamped in place. The alternator keeps the pair charged, and heavy cables tie the batteries to each other and to the rest of your Powerstroke starting circuit.

What fails and why

Batteries are where most hard-start complaints on this truck begin. Weak or mismatched batteries, plus voltage drop at the cables and grounds, show up as slow cranks, extended cranks and a truck that will not light on the first try in the cold. Expect three to five years of battery life. A weak battery does damage beyond the starting circuit too: it overworks the alternator and causes premature alternator failure. Load-test the pair once a year and replace both batteries at the same time, never one alone.

Stock replacement vs. upgrade

For a stock truck, a matched pair of 750 CCA Group 65 batteries is the OE-equivalent choice. AGM Group 65 pairs make sense on high-draw trucks and in cold climates. A billet hold-down replaces the factory bracket, and owners pick one when the factory piece is missing or damaged, or simply to put cleaner hardware under the hood.

What we carry

Here you will find billet battery hold-downs. S&B makes the 72-1000 billet battery hold-down bracket set for 2011-2022 6.7L trucks. SPE Motorsport offers the S100166 billet battery hold-down, and No Limit Fabrication makes the 67BH battery hold-down kit, with each of those listing 2011-2024 6.7L fitment. Choose by finish and style, since each one does the same job of clamping the battery in its tray.

Fitment notes

Every hold-down here lists a 6.7L range that starts in 2011 and runs past 2014, so your truck is covered. If you are replacing batteries at the same time, stay with Group 65 sizing so the battery seats in the tray the way the factory intended and the hold-down clamps it properly. If you have any doubt, verify by VIN with the fitment checker on the product page.

Frequently asked questions

What battery size does a 2011-2014 6.7L Powerstroke use?

Two Group 65 batteries wired in parallel. The common OE-equivalent rating is 750 CCA, and replacements run from about 650 to 950 CCA in flooded or AGM construction.

Can I replace just one battery?

No. A weak battery drags the pair down and overworks the alternator, which leads to early alternator failure. Replace both batteries together, and load-test them once a year to catch a weak one before it strands you.

Is an AGM battery pair worth it on this truck?

AGM Group 65 pairs suit trucks with high electrical draw and trucks that live in cold climates. If your truck is stock and the winters are mild, a matched flooded 750 CCA pair is the OE-equivalent choice.

Why would I buy a billet battery hold-down?

It replaces the factory bracket that clamps the battery in its tray. Owners pick one when the factory piece is missing or damaged, or when they want billet hardware under the hood.
