Your Ford F350 diesel doesn’t ask politely when it wants to start. A 6.7L or 6.0L Power Stroke turns over a high-compression engine and drives twin batteries plus a serious load of glow plugs, lift pumps, and accessories. When one battery gets weak, the truck cranks slow, throws codes, or simply won’t fire on a cold morning. That’s why picking the right Group 65 battery matters more on a Super Duty than on almost any other vehicle on the road.
We focused on batteries that genuinely fit the F350 dual-battery tray, deliver the high cold cranking amps a diesel needs, and survive the heat and vibration of a working truck. Below are seven batteries we would actually bolt into a Power Stroke, ranked best first, with honest notes on where each one falls short.

1. Odyssey 65-PC1750T Performance Series Battery: Best Overall
The Odyssey 65-PC1750T is the battery we reach for first when an F350 diesel needs to start every single time, regardless of weather. Its Thin Plate Pure Lead construction packs more active material into the Group 65 case than a normal flooded battery, which translates to 950 cold cranking amps and a brutal 1750 cranking-amp burst. On a 6.7 Power Stroke with two of these on the tray, the engine spins like it’s warm even in deep winter. The sealed AGM design also shrugs off the constant vibration of a loaded work truck or a trail rig.
The honest weakness is weight and the fact that you really want to run a matched pair. These are dense batteries, noticeably heavier than a budget flooded unit, so swapping both is a workout. Odyssey also rewards proper charging, so if your truck has a tired alternator or you let it sit deeply discharged, you won’t see the full lifespan the design is capable of. Treat it right and it outlasts almost anything else here.
- Thin Plate Pure Lead (TPPL) design for massive cranking output
- Rated for deep cycling and extreme vibration in working trucks
- Long service life with strong heat and cold tolerance
Pros: Enormous cranking power that spins a cold Power Stroke fast; Exceptional vibration resistance for off-road and towing use; Long lifespan compared to standard flooded batteries
Cons: Heavier than most Group 65 batteries; Premium positioning means it sits at the top of its class
2. XS Power D6500 XS Series AGM Battery: Best High-Output
The XS Power D6500 comes from the car audio and high-amp world, and it shows. With cranking numbers that exceed almost everything in this guide, it’s the pick for an F350 diesel that has been built up with extra electronics, a winch, auxiliary lighting, or a big inverter. The sealed AGM chemistry means no spills and no maintenance, and it tolerates aggressive charge and discharge cycles better than a flooded battery. For a truck that works hard and carries a lot of added load, this thing has headroom to spare.
That overbuilt nature is also its drawback. If you drive a mostly stock Super Duty, you’re paying for capacity you may never use, and the D6500 is heavier and denser than a standard Group 65. The terminal setup also benefits from clean, properly torqued connections, so a sloppy install can cost you performance. For a modified or heavily accessorized diesel, though, few batteries crank harder.
- Sealed AGM with very high cranking amp output
- Strong reserve capacity for added electronics and accessories
- Spill-proof and mountable in demanding positions
Pros: Outstanding raw cranking amps for hard-starting diesels; Handles big aftermarket electrical loads and winches well; Sealed maintenance-free design
Cons: More than most owners need for a stock truck; Terminal hardware can require care during install
3. ACDelco 65AGM Professional AGM Battery: Best OEM-Style
If you want a battery that behaves exactly the way the factory intended, the ACDelco 65AGM is the safe, smart choice for a Ford F350 diesel. ACDelco builds to OEM specifications, so the size, terminal layout, and venting drop straight into the Super Duty tray with no surprises. The AGM chemistry gives you strong cold cranking, good vibration resistance, and a genuinely maintenance-free life. For owners who just want their truck to start and last without drama, this is a no-fuss answer.
The trade-off is that it’s built to be dependable rather than extreme. Its cranking numbers are very good but don’t match the Odyssey or the XS Power high-output units, so a heavily modified electrical system might want more. Stock availability can also swing depending on your area and supplier. For a stock-to-mild F350 that needs trustworthy OEM-style performance, it’s hard to go wrong here.
- AGM construction with strong cold cranking performance
- High-density negative paste for longer life and cycling
- Sealed design resists vibration and acid leaks
Pros: Reliable OEM-grade quality and consistent fitment; Solid cold cranking for the F350 dual-battery setup; Maintenance-free and widely trusted
Cons: Cranking specs trail the top high-output picks; Availability can vary by region
4. Optima YellowTop H6 Dual Purpose Battery: Best Dual-Purpose
The Optima YellowTop H6 is the battery to choose when your F350 diesel does more than just drive. If you run a plow, a winch, work lights, a fridge, or sit with the key on running electronics, the YellowTop’s dual-purpose SpiralCell design lets it crank the engine and survive repeated deep discharges that would kill a pure starting battery. The spiral-wound cells are famously tough against vibration, which suits a truck that spends time on rough ground or hauling heavy loads.
The honest catch is that being good at two jobs means it isn’t the absolute champion at either. Its cold cranking amps sit below the dedicated starting monsters like the Odyssey, so in brutal cold a stock truck might prefer a pure cranker. You also pay a premium for the dual-purpose engineering. For a working diesel with a heavy accessory appetite, though, the YellowTop is the most flexible battery here.
- SpiralCell AGM design for starting and deep cycling
- Excellent vibration resistance from spiral-wound cells
- Strong reserve capacity for accessory-heavy trucks
Pros: Handles both cranking and deep-cycle accessory loads; Very vibration resistant for work and off-road use; Recovers well from deep discharges
Cons: Cold cranking amps lower than dedicated starting AGMs; Premium price for the dual-purpose ability
5. DieHard Platinum AGM Group 65 Battery: Best Cold-Weather
The DieHard Platinum AGM in Group 65 is a strong cold-weather choice for the F350 diesel, which is exactly where a Power Stroke is most likely to leave you stranded. AGM construction gives it the fast, confident cranking you want when temperatures drop and the glow plugs are working overtime. It’s sealed and maintenance-free, so once it’s bolted to the tray you can forget about it, and it carries enough reserve capacity to handle the accessory load most owners pile onto a Super Duty.
The thing to be aware of is that the DieHard name has changed ownership over the years, and reported quality has been less consistent than it once was, so buying from a reputable seller matters. Its cranking output, while genuinely good, doesn’t top the high-output AGM units in this guide. For a winter-driven diesel that needs reliable cold starts without fuss, it remains a sensible pick.
- AGM design tuned for strong cold cranking
- Sealed and maintenance-free for hands-off ownership
- Good reserve capacity for accessory loads
Pros: Dependable cold-start performance in winter; Trusted long-standing battery brand; Sealed, leak-resistant construction
Cons: Brand has changed hands and quality reputation varies; Not the highest cranking output in the group
6. Duracell Ultra Platinum AGM Group 65 Battery: Best Value AGM
The Duracell Ultra Platinum AGM in Group 65 is the value sweet spot for an F350 diesel owner who wants real AGM performance without reaching for the most premium names. It cranks strongly, fits the dual-battery tray cleanly, and gives you the sealed, maintenance-free convenience that makes AGM worth choosing over flooded. For a daily-driven Super Duty that tows and works but isn’t heavily modified, it covers the job confidently and represents genuinely sensible value.
Where it gives a little ground is at the very top end of longevity. Premium units like the Odyssey will generally outlast it under hard, repeated deep-discharge abuse, and warranty support can vary depending on which retailer you buy through. For most owners running a stock-to-mild diesel who want dependable cranking and a fair deal, the Duracell Ultra Platinum is an easy battery to recommend.
- AGM build delivers strong cranking and cycle life
- Sealed, spill-proof, and maintenance-free
- Good vibration resistance for daily truck duty
Pros: Strong cranking performance for the value; Maintenance-free AGM convenience; Reliable everyday fitment for the F350 tray
Cons: Lifespan trails the very top premium AGM units; Warranty handling depends on the retailer
7. EverStart Maxx Group 65 Lead-Acid Battery: Best Budget Pick
The EverStart Maxx in Group 65 is the practical, accessible choice for an F350 diesel owner who needs reliable starting without the premium of AGM. It’s a flooded lead-acid battery with genuinely strong cold cranking amps, and it drops straight into the Super Duty tray with the correct terminal layout. For a truck that mostly commutes and tows in moderate conditions, a matched pair will turn over the engine dependably and keep your money in your pocket for fuel.
The compromise is what you’d expect from flooded chemistry. It doesn’t tolerate severe vibration, deep cycling, or extreme heat as well as the AGM options, and its overall lifespan tends to be shorter, especially under the abuse a hard-working diesel can dish out. If you live somewhere brutally cold or run heavy accessory loads, an AGM is the wiser long-term call. As a straightforward, dependable budget battery, though, the EverStart Maxx earns its place.
- Flooded lead-acid build with strong cold cranking amps
- Direct OEM-style fitment for the F350 tray
- Maintenance-free top-post design
Pros: Strong cranking power for an accessible flooded battery; Easy fitment and wide availability; Good honest value for a daily driver
Cons: Flooded design is less vibration and heat tolerant than AGM; Shorter expected lifespan than premium AGM units
Frequently Asked Questions
What size battery does a Ford F350 diesel use?
Most modern Ford F350 diesel trucks, including the 6.7L and 6.0L Power Stroke, use a BCI Group 65 battery, and the diesel models run two of them in parallel on a dual-battery tray. The Group 65 has a top-post terminal layout that drops straight into the Super Duty tray. When you replace them, it’s strongly recommended to replace both batteries at the same time with matched units, because mixing an old battery with a new one drags the new one down and shortens its life.
How many cold cranking amps do I need for an F350 diesel?
Diesels need far more cranking power than gas engines because they have high compression and run glow plugs. For an F350 diesel you want each battery to deliver high cold cranking amps, ideally in the 750 to 950 CCA range or more per battery, and with two batteries working together you get a combined output that spins the engine fast even in cold weather. If you live in a cold climate or have added electronics, lean toward the higher CCA AGM options like the Odyssey or XS Power for confident winter starts.
Should I use AGM or flooded batteries in my Power Stroke?
AGM batteries are the better choice for most F350 diesel owners. They resist vibration far better, tolerate heat under the hood, handle deep discharges from accessories, and last longer than traditional flooded lead-acid batteries. Flooded options like the EverStart Maxx still crank well and offer good value for a mostly stock truck in mild conditions, but if you tow heavy, run plows or winches, drive in extreme temperatures, or want maximum lifespan, AGM is worth the extra investment.
Do I have to replace both F350 batteries at the same time?
Yes, you should replace both batteries together as a matched pair. The two batteries in an F350 diesel work in parallel and share the load, so if one is weak or older, it pulls down the stronger battery and accelerates its wear. Pairing batteries of different ages, brands, or cranking ratings creates an imbalance that leads to premature failure and inconsistent starting. Always install two identical batteries of the same type, age, and rating for the best reliability and lifespan.
Why does my F350 diesel kill batteries faster than a gas truck?
A diesel Super Duty puts much higher demand on its batteries than a gas truck. It draws heavily during cold starts, powers glow plugs, runs lift and fuel pumps, and often carries added electronics, plow controls, or inverters. Heat under a diesel hood and constant vibration from towing and rough use also wear batteries down. Choosing a vibration-resistant AGM battery with high cold cranking amps and strong reserve capacity, and keeping your charging system healthy, are the best ways to extend battery life in a Power Stroke.
Our Verdict
For most Ford F350 diesel owners, the Odyssey 65-PC1750T is our top pick. Its Thin Plate Pure Lead design delivers the relentless cranking power, vibration resistance, and long lifespan a hard-working Power Stroke demands, especially in cold weather. If you have built up your truck with extra electronics, a winch, or heavy accessory loads, the XS Power D6500 is the runner up, offering even higher raw output with the headroom to feed a demanding electrical system. Whichever you choose, install a matched pair, keep your charging system healthy, and your Super Duty will start strong for years.
