Pick the wrong group size and the battery either will not fit or will sit loose in the tray. That is the real problem behind the search for the best battery for Ford F150 trucks, because Ford has used Group 65, H6 (Group 48), H7 (94R) and H8 (Group 49) batteries across different years and engines.

Find Your F150’s Battery Size First
Recommended Best Deal Products
Size is the first filter, and fitment sources do not always agree. Use this table as a starting point, then check the label on your current battery.
| Truck | Typical size | Notes |
|---|---|---|
| 2004–2014 | Group 65 | Used in most trims and engines. |
| 2015 | H6 (XL, XLT) or H7 / 94R (Lariat and above) | Owner reports for the 2.7L EcoBoost; check the label. |
| 2016–2020 | Mostly H6 (Group 48) | Some charts list Group 65 for the 5.0L and 3.5L; sources disagree. |
| 2018–2021, 3.0L Power Stroke | H8 (Group 49) | Original-equipment size for the diesel. |
| 2021–2025 | H6, H7 or H8 by engine and trim | Owners report one tray accepts up to H8; the PowerBoost hybrid is the exception. |
1. ACDelco Gold 48AGM (88864541) Group 48 AGM Battery
The safest H6 replacement for F150s with start-stop, from a brand most buyers already recognize.
| BCI group | 48 (H6) |
| Type | AGM |
| Cold cranking amps | 760 CCA |
| Reserve capacity | 120 minutes |
| Capacity | 70 Ah |
| Warranty | 36-month free replacement |
| Dimensions | — (not shown on the listing we reviewed) |
✔ Pros
- Recognizable brand with a 36-month free-replacement period
- AGM build made for stop/start vehicles
- 760 CCA is in line with what H6 F150s ship with
- Sealed, spill-proof glass-mat design
✘ Cons
- Length and terminal layout were not on the listing we reviewed, so confirm before ordering
- Fits H6 trays only, not Group 65 or 94R trucks
- Smaller capacity than the H7 and H8 options for trucks with heavy accessory loads
The ACDelco Gold 48AGM takes Best Overall because it covers the most common modern F150 fitment, Group 48 (H6), and it comes from a name with a long track record. ACDelco describes the battery as a glass-mat AGM built for stop/start vehicles, with the electrolyte held in the separator so nothing can slosh or spill.
Published figures from a third-party buyer’s guide list it at 760 CCA, 120 minutes of reserve capacity and 70 Ah. That puts it level with the other H6 AGMs in this roundup on paper. The difference is the warranty framing: a 36-month free-replacement period from a brand with a large service network behind it.
The weak spot is information, not performance. The listing we reviewed did not give length or terminal position, and the other H6 batteries here list a 10.94-inch length while one fitment chart puts a Group 48 closer to 12 inches. Measure your tray and your old battery before you order.
If your truck is a 2015 Lariat or newer and came with an H7 battery, jump to the ACDelco 94R instead.
Who should buy it: Owners of 2015+ F150s with an H6 tray who want a known brand and a 36-month replacement window.

2. ACDelco Professional 94RAGM Group 94R AGM Battery
Recommended Best Deal Products
The direct-fit choice for F150s that left the factory with an H7 (94R) battery.
| BCI group | 94R (H7) |
| Type | AGM |
| Warranty | 36-month free replacement |
| Cold cranking amps | — (not confirmed from our sources) |
| Capacity | — (not confirmed) |
| Dimensions | — (not shown on the listing we reviewed) |
✔ Pros
- Matches the H7 size used on 2015 Lariat, King Ranch and Platinum trims
- Same brand and 36-month replacement terms as the overall winner
- AGM design for stop/start duty
✘ Cons
- The listing we reviewed gives no CCA or amp-hour figure, so we do not quote one
- Longer than an H6, so it is not a swap for H6-only trays
- Heavier than the Group 48 batteries in this list
Ford fitted two AGM sizes to the 2015 F150 with the 2.7L EcoBoost: owners report H6 on XL and XLT, and H7 (94R) on Lariat, King Ranch and Platinum. If your truck came with the larger battery, the 94R is the size to match, and ACDelco’s 94RAGM is the most recognizable brand in that format on this list.
ACDelco’s description covers the usual AGM points: glass-mat construction, high cycling capability, a vent-cap design that resists acid leaks, and a 36-month free-replacement period. A separate 2026 roundup also picks the ACDelco 94R AGM as its H7 replacement.
We could not confirm cold cranking amps or capacity for this listing, so we are not printing numbers we cannot back up. If cold-start rating is the deciding factor, the Weize 94R publishes 850 CCA and 140 minutes of reserve on its page.
Check the old battery’s label before buying. The 94R is about an inch and a half longer than the shorter H6 units.
Who should buy it: Owners of H7-equipped F150s who prefer a major brand over a generic.

3. Mighty Max Battery MM-H6 Group 48 AGM Start-Stop Battery
A fully specified H6 AGM with a three-year warranty and mounting screws included.
| BCI group | 48 (H6) |
| Type | AGM |
| Cold cranking amps | 760 CCA |
| Reserve capacity | 120 minutes |
| Capacity | 70 Ah |
| Dimensions | 10.94 x 6.88 x 7.48 in |
| Terminals | Positive right, negative left |
| Warranty | 3 years |
✔ Pros
- Complete spec listing, including dimensions and terminal side
- Three-year warranty
- Mounting screws included
- Can be mounted in any position except upside down
✘ Cons
- Wiring harness and mounting accessories are not included
- Generic brand with no independent F150 testing that we could find
- Listed length is shorter than a BCI-chart Group 48
Mighty Max earns Best Value for how much it tells you before you buy. The listing gives 760 CCA, 120 minutes of reserve, 70 Ah, dimensions, terminal side and a three-year warranty, and it states plainly that the wiring harness is not included. That level of detail is rare among generic AGM batteries.
The maker says the MM-H6 is built in an ISO-certified facility and meets CE quality and safety standards, and describes a sealed, spill-proof AGM design that recovers from deep discharge. Those are manufacturer claims, not test results.
The caution is the same one that applies to every shorter H6 here: the listed 10.94-inch length is about an inch shorter than the 12-inch figure in some fitment charts. Check that the hold-down still grips it properly.
For a higher-capacity upgrade, see the Weize Group 49.
Who should buy it: Buyers who want a well-documented H6 AGM with a three-year warranty from a lesser-known brand.
Availability last checked October 2026.
4. UPLUS BCI Group 48 AGM-L70-M 12V 70Ah AGM Battery
The H6 listing with the most complete data sheet, including cranking amps and retention code.
| BCI group | 48 (H6 / L3) |
| Type | AGM |
| Cold cranking amps | 760 CCA at -0.4 °F |
| Cranking amps | 875 CA at 32 °F |
| Reserve capacity | 120 minutes at 25 A |
| Capacity | 70 Ah (20 hr) |
| Max dimensions | 10.98 x 6.81 x 7.52 in |
| Polarity | Right-hand positive |
| Retention | B13 |
| Weight | 46.53 lb |
| Warranty | 3 years |
✔ Pros
- Most detailed data sheet of any battery in this list
- Right-hand-positive polarity and B13 retention code are stated
- Three-year warranty with a US service office claimed
✘ Cons
- Lesser-known brand with limited independent coverage
- The 4x cycle-life claim is a manufacturer figure we could not verify
- Heavy at 46.5 lb
UPLUS earns Best Documented Specs because its listing reads like a real data sheet: 760 CCA measured at -0.4 °F, 875 cranking amps at 32 °F, reserve capacity at a stated 25 A load, a B13 retention code, maximum dimensions and weight. If you like to compare numbers against your old battery’s label, this is the easiest battery here to check.
The company says the battery uses high-density negative paste and a calcium-silver alloy, and claims four times the cycle life of a standard flooded battery. Treat that as marketing until independent testing says otherwise. The listing also repeats the rule that matters most for modern trucks: replace an AGM with another AGM.
On the downside, UPLUS is not a household name and we found no independent F150 tests. The three-year warranty and the stated California and Georgia warehouse support are the main reassurance.
If you would rather have a recognizable name in the same size, go back to the ACDelco 48AGM.
Who should buy it: Owners who want to check every number against the old battery before buying an H6 AGM.

5. Weize Platinum AGM BCI Group 94R (H7) 12V 80Ah Battery
The highest-rated starting power among the H7 options, for trucks that see real winters.
| BCI group | 94R (H7) |
| Type | AGM |
| Cold cranking amps | 850 CCA |
| Reserve capacity | 140 minutes |
| Capacity | 80 Ah |
| Dimensions | 12.4 x 6.89 x 7.48 in |
| Terminals | Positive right, negative left |
| Operating range | -22 °F to 158 °F |
| Warranty | 36 months |
✔ Pros
- 850 CCA and 140 minutes of reserve capacity
- Published operating range from -22 °F to 158 °F
- Low stated self-discharge: under 8% after 90 days
- Dimensions and terminal side are listed
✘ Cons
- Same-brand overlap: four of the ten picks here are Weize
- No independent reviews for the brand that we could find
- Not for H6-only trays
If winter starts are the main worry, the Weize 94R gives the strongest published numbers among the H7 batteries here: 850 CCA, 140 minutes of reserve and 80 Ah. The listing also states an operating range of -22 °F to 158 °F and a self-discharge rate under 8% after 90 days of storage.
The dimensions are 12.4 x 6.89 x 7.48 inches with the positive terminal on the right, which is the layout described for the H7 size. That makes it a plausible match for 2015 Lariat-and-up trucks and for Gen-14 trucks that ship with H7, though you should still compare it against the old battery.
The honest drawback is brand depth. Weize sells through Amazon and we found no independent reviews, so the 36-month warranty is the safety net. Four of the ten batteries in this roundup carry the Weize name, which is why the methodology section explains how we handled that.
For H7 trucks where brand recognition matters more than CCA, see the ACDelco 94R.
Who should buy it: Owners of H7-equipped F150s in cold regions who want the highest published cranking rating in this size.
Availability last checked October 2026.
6. Weize Platinum AGM BCI Group 49 (H8) 95Ah Battery
The biggest battery on the list, and the right one for 3.0L Power Stroke trucks and owners who want extra reserve.
| BCI group | 49 (H8) |
| Type | AGM |
| Cold cranking amps | 900 CCA |
| Reserve capacity | 160 minutes |
| Capacity | 95 Ah |
| Dimensions | 13.9 x 6.89 x 7.48 in |
| Terminals | Positive right, negative left |
| Warranty | 36 months |
✔ Pros
- 900 CCA, 160 minutes of reserve and 95 Ah, the highest figures in this roundup
- Correct size for 2018 to 2021 3.0L Power Stroke F150s
- Many Gen-14 owners report H8 fits the stock tray
✘ Cons
- Does not fit the PowerBoost hybrid, which has a module in the way
- Owners disagree on whether stock cables reach the terminals
- The listing contains conflicting text (one line says 60 Ah and 680 CCA); we used the 95 Ah, 900 CCA figures that match other listings
Group 49, also sold as H8, is the largest battery in this roundup and the only one that is original equipment on some F150s. Retailer fitment data lists it for the 3.0L Power Stroke trucks from 2018 to 2021, and one dealer service guide says Ford’s 3.0L Power Stroke diesels require the larger H8.
On Gen-14 trucks (2021 to 2025) the picture is more flexible. Owners report that Ford installs H6, H7 or H8 depending on engine and trim, using the same tray and cable assembly, and that the tray accepts up to an H8. The exception is the PowerBoost hybrid, where an extra module blocks the longer battery.
The Weize listing quotes 95 Ah, 900 CCA and 160 minutes of reserve. One summary line on the page contradicts those figures, so confirm the specs on the product page before you buy. Some owners also recommend a battery insulator blanket sized for the H8, and not everyone agrees the stock cables reach.
If your tray is H6-only and you want the least hassle, the ACDelco 48AGM is the simpler swap.
Who should buy it: Owners of 3.0L Power Stroke F150s, or non-hybrid Gen-14 owners who want the most reserve capacity and have checked tray space.
Availability last checked October 2026.
7. Weize Platinum AGM Group 48 (H6) 12V 70Ah Battery
A conventional H6 AGM with clear dimensions, held back by a listing that contradicts itself.
| BCI group | 48 (H6) |
| Type | AGM |
| Cold cranking amps | 760 CCA |
| Reserve capacity | 120 minutes |
| Capacity | 70 Ah |
| Dimensions | 10.94 x 6.89 x 7.48 in |
| Terminals | Positive right, negative left |
| Operating range | -22 °F to 158 °F |
| Warranty | — (not stated on the listing we reviewed) |
✔ Pros
- Dimensions and terminal layout are published
- Operating range of -22 °F to 158 °F
- Same 760 CCA and 70 Ah as the other H6 options
✘ Cons
- The listing contains a line quoting 60 Ah and 680 CCA, which conflicts with the headline specs
- Warranty length is not stated on the page we reviewed
- One of four Weize batteries in this list
This Weize battery is a straightforward Group 48 AGM: 70 Ah, 760 CCA, 120 minutes of reserve, and a stated 10.94 x 6.89 x 7.48 inch footprint with the positive terminal on the right. It targets the same stop/start trucks as the ACDelco and Mighty Max H6 batteries.
The listing also describes an operating range of -22 °F to 158 °F, a charge voltage range of 14.4 to 15.0 V and a sealed, spill-resistant build. The generic AGM caveat applies: it is a starting battery and the maker says it is not meant for deep-cycle use such as solar projects.
Our concern is accuracy. One bullet on the page quotes 60 Ah and 680 CCA, which looks like text copied from a different size. Before ordering, read the full specification section and confirm the numbers match what you expect.
For an H6 with a clearer warranty statement, the Mighty Max MM-H6 is the better-documented choice.
Who should buy it: Owners who want a generic H6 AGM and are willing to double-check the listing details first.
Availability last checked October 2026.
8. Renogy 12V 70Ah AGM Group 48 Start-Stop Car Battery
A sealed H6 AGM with a wide operating range, but the lowest cranking rating of the Group 48 batteries here.
| BCI group | 48 (H6) |
| Type | AGM |
| Cold cranking amps | 720 CCA |
| Reserve capacity | 120 minutes |
| Capacity | 70 Ah |
| Operating range | -22 °F to 158 °F |
| Warranty | — (not stated on the listing we reviewed) |
| Dimensions | — (not shown on the listing we reviewed) |
✔ Pros
- Sealed design that limits acid leaks and corrosion
- Published operating range of -22 °F to 158 °F
- Stop/start cycling is a stated design goal
✘ Cons
- 720 CCA is the lowest among the Group 48 batteries in this roundup
- Renogy is best known for solar equipment, not starting batteries
- The product page offers 100 Ah and 200 Ah variants; pick the Group 48 option
Renogy is better known for solar kits, but this 70 Ah Group 48 AGM is sold as a start-stop automotive replacement for compact cars, sedans, SUVs, crossovers and light trucks. It lists 720 CCA and 120 minutes of reserve capacity in a sealed AGM case.
The operating range is stated as -22 °F to 158 °F, and the maker says the design is optimized for the frequent restarts of start-stop systems. Those are the right priorities for a modern F150.
The trade-off is cranking power. At 720 CCA this is the lowest-rated Group 48 battery here, so it suits trucks in moderate climates better than ones that see deep cold. Also note that the product page includes 100 Ah and 200 Ah options, so make sure the selector is on the Group 48 battery before you add it to your cart.
For a higher CCA at the same size, compare the ACDelco 48AGM and the UPLUS.
Who should buy it: F150 owners with an H6 tray and mild winters who prefer a sealed, start-stop-focused AGM.

9. Weize Platinum AGM Group 65 12V 70Ah Battery
A Group 65 AGM upgrade for older F150s that came with the big, tall battery.
| BCI group | 65 |
| Type | AGM |
| Cold cranking amps | 750 CCA |
| Reserve capacity | 120 minutes |
| Capacity | 70 Ah |
| Dimensions | 12.05 x 7.56 x 7.56 in |
| Terminals | Positive left, negative right (per listing) |
| Warranty | 3 years |
✔ Pros
- Right size for F150s from 2004 to 2014, which used Group 65
- Dimensions and terminal layout are published
- 750 CCA matches common Group 65 AGM ratings
✘ Cons
- Group 65 is not the right size for most 2016+ trucks
- Terminal polarity should be checked against your old battery
- AGM is an upgrade, not a requirement, on trucks without start-stop
Group 65 was the standard F150 battery for roughly 2004 to 2014, and fitment charts also list it on some 2015 to 2020 and later 5.0L V8 builds. This Weize is a 70 Ah, 750 CCA AGM in that size, with a listed footprint of 12.05 x 7.56 x 7.56 inches.
The listing stresses a point worth repeating: if your truck’s original battery was an AGM, you must replace it with an AGM. Older trucks without start-stop never needed AGM, so on those it is an optional upgrade for better vibration resistance and shelf life.
Fitment sources disagree on newer trucks. Some list Group 65 for the 5.0L and the 3.5L EcoBoost from 2015 to 2020, while others list H6. Read the label on your current battery rather than trusting a chart.
The listing says the positive terminal is on the left. Compare that with your cables before you buy, because reversed polarity will not reach.
If your truck is newer, start with the ACDelco 48AGM.
Who should buy it: Owners of 2004 to 2014 F150s, and 5.0L V8 trucks that use a Group 65 tray.
Availability last checked October 2026.
10. Autocessking AGM Start-Stop Group 65 12V 70Ah Battery
A second Group 65 AGM option with the same size and rating as the Weize, but little detail beyond the basics.
| BCI group | 65 |
| Type | AGM |
| Cold cranking amps | 750 CCA |
| Reserve capacity | 120 minutes |
| Capacity | 70 Ah |
| Dimensions | 12.05 x 7.56 x 7.56 in |
| Terminals | Positive left, negative right (per listing) |
| Warranty | 36 months |
✔ Pros
- Same Group 65 footprint and 750 CCA rating as the Weize 65
- Dimensions and terminal layout are published
- 36-month warranty
✘ Cons
- Least-documented brand in this roundup
- Listing gives few construction details
- Same polarity and fitment checks apply as for any Group 65
The Autocessking Group 65 matches the Weize on every headline number: 70 Ah, 750 CCA, 120 minutes of reserve and a 12.05 x 7.56 x 7.56 inch case, with the positive terminal on the left per the listing. That makes it a direct alternative for older F150s and Group 65 V8 trucks.
The listing stresses AGM safety and heat resistance and states low self-discharge, which helps trucks that sit between uses. It is explicit that this is a starting battery and should not be used in deep-cycle roles such as solar projects.
Our reservation is brand transparency. This is the least-documented battery in the list, so it sits last: we found no independent reviews and little beyond the basic specification. If you want a Group 65 AGM with a bit more supporting detail, the Weize 65 is the safer pick.
As with every battery here, check polarity and the hold-down fit before you commit.
Who should buy it: Owners of Group 65 trucks who want a second option and are comfortable with a less-documented brand.
Availability last checked October 2026.
What to Look for in a Ford F150 Battery
Match the group size and tray first
The group label sets length, width, height and terminal side. Group 65 is the taller, wider older size, while H6, H7 and H8 are progressively longer. Many Gen-14 owners report that one tray accepts up to an H8 on non-hybrid trucks, but measure yours and check the hold-down.
Choose AGM if your truck has start-stop
Trucks with auto start-stop need an AGM battery that tolerates repeated cycling. If your original battery is an AGM, replace it with another AGM, because modern electrical systems are built around that chemistry.
Read CCA together with reserve capacity
CCA describes cold-start power, while reserve capacity shows how long the battery can carry accessories. For H6 and H7 sizes, ratings of roughly 760 to 850 CCA are common. Cold-region owners and trucks with heavy accessory loads gain from the higher numbers.
Check dimensions, not just the label
The batteries in this list marketed as Group 48 state a length near 10.94 inches, while a BCI-chart figure for Group 48 is about 12 inches. The label alone does not guarantee a snug fit, so compare the listed length against your old battery.
Confirm terminal polarity
Most listings here put the positive terminal on the right, but the two Group 65 batteries put it on the left. Reversed polarity means the cables will not reach.
Weigh warranty and brand transparency
A three-year warranty is useful, but only if you can claim it easily. Prefer listings that publish complete specs, and be cautious with lines that conflict with the headline figures.
Common Mistakes to Avoid
- Buying by group number alone without comparing the listed length and terminal side to your old battery.
- Replacing an AGM battery with a conventional flooded one on a start-stop truck.
- Trusting a single bullet in a listing without checking it against the specification section.
- Forgetting that Gen-14 owners often report the truck’s battery monitoring system needs a reset or re-learn after a swap. Check your owner’s manual or ask a shop.
- Ordering a bigger H8 for a PowerBoost hybrid, where an internal module blocks the longer case.
Frequently Asked Questions
What size battery does a Ford F150 take?
It depends on the year and engine. Trucks from 2004 to 2014 mostly use Group 65. Many 2015 and later trucks use H6 (Group 48) or H7 (94R), the 3.0L Power Stroke uses H8 (Group 49), and Gen-14 trucks vary by engine and trim. Check the label on your current battery.
Does an F150 need an AGM battery?
If your truck has auto start-stop, or originally came with an AGM battery, yes. The system expects a battery that tolerates frequent cycling. Older trucks without start-stop did not require AGM, so on those it is an optional upgrade.
How many CCA does an F150 need?
Match or exceed the rating on your original battery. Retailer listings for F150 AGM batteries commonly run from roughly 750 to 850 CCA. Owners in cold climates tend to pick the upper end of that range for easier winter starts.
Can I put an H8 (Group 49) in my F150?
Owners report the Gen-14 tray, hold-down and cables accommodate up to an H8 on non-hybrid trucks, and some 2018 and later Gen-13 owners report the same. The PowerBoost hybrid cannot take an H8 because of an internal module. Measure your tray before you order.
Do I have to reset anything after replacing the battery?
Many Gen-14 owners report that the battery monitoring system needs a reset or re-learn after a swap, and that skipping it can cause odd behavior such as start-stop not working. Follow your owner’s manual or ask a shop about the correct procedure for your model year.
Is a shorter battery a problem if my tray is bigger?
It can be. A battery that is about an inch shorter than your tray was designed for may sit loosely unless the hold-down grips it firmly. Compare the listed length and width against your old battery and make sure the hold-down secures it.
Our Verdict
For most trucks with an H6 tray, the ACDelco Gold 48AGM is the safest pick: a recognizable brand, AGM construction and a 36-month replacement window. If your F150 came with an H7 battery and you live somewhere cold, the Weize 94R publishes the strongest cranking numbers in that size.
For a 3.0L Power Stroke or a non-hybrid Gen-14 truck where you want maximum reserve, the Weize Group 49 is the biggest option, and for 2004 to 2014 trucks the Weize Group 65 is the match. Whatever you choose, confirm size, polarity and hold-down fit first.
