Ford F150 Battery Size Chart: Year and Engine 2004-2026

The correct Ford F150 battery size depends on the model year, engine, trim, and electrical package. Older trucks commonly use Group 65 batteries, while newer F-150s use H6, H7, and in one diesel application H8 batteries.

You should not buy a battery from model year alone when Ford lists more than one factory option. For example, Ford documentation for 2016 lists both H6 and H7 batteries depending on engine and trim.

Use the Ford F150 battery size chart below to narrow down the correct group, then match the battery already installed in your truck or confirm the fitment by VIN before ordering.

Ford F150 Battery Size Chart by Year 2004 to 2026

The table below combines Ford owner manual data with established battery application information. Where Ford offered more than one battery, both options are shown instead of assigning one size to the entire model year.

Ford’s 2014 owner’s manual lists BXT-65-750 across the 3.5L EcoBoost, 3.7L V6, 5.0L V8, and 6.2L V8, confirming Group 65 with a 750 CCA Motorcraft battery for that model year.

The major change arrives with the aluminum-body generation. Ford’s 2016 manual lists 48H6 and 94RH7 batteries, including BAGM-48H6-760 and BAGM-94RH7-800 for the 2.7L EcoBoost. The same manual lists 610 CCA H6 and 730 CCA H7 flooded batteries for several other engines.

The 3.0L Power Stroke is the important exception. Ford specifies the larger BAGM-49H8-850, an AGM H8 battery rated at 850 CCA, for the 2019 diesel.

For replacement options rather than factory specifications, our best batteries for the Ford F150 guide covers battery choices separately.

H6 vs H7 vs H8 and Group 65 Battery Dimensions

Battery group numbers describe the physical case size, terminal arrangement, and mounting format. They do not automatically tell you the battery’s chemistry or exact CCA.

H6, H7, and H8 are also commonly sold under BCI-style equivalent designations.

Interstate’s application guide lists its H6 batteries at roughly 10 15/16 inches long, 6 7/8 inches wide, and 7 1/2 inches high. Its H7 batteries measure about 12 3/8 × 6 7/8 × 7 1/2 inches.

Its current battery specifications place H8 at about 13.9 × 6.89 × 7.48 inches.

That extra length matters. An H7 is not simply a higher-powered H6. The battery tray, hold-down, cables, and terminal position must accommodate the larger case.

What CCA Does Your Ford F150 Need

Group size tells you whether the battery physically fits. Cold Cranking Amps, or CCA, tells you how much starting current the battery can deliver at low temperature.

Ford’s factory ratings show why group size and CCA need to be checked separately.

For the 2016 F-150, Ford lists:

• H6 AGM: 760 CCA
• H7 AGM: 800 CCA
• H6 flooded: 610 CCA
• H7 flooded: 730 CCA

Those values come directly from Ford’s Motorcraft battery part numbers for the different engines and trim configurations.

For 2014, Ford specifies BXT-65-750, which corresponds to a Group 65 battery rated at 750 CCA.

The 2019 3.0L Power Stroke moves higher again with the H8 AGM 850 CCA battery.

Do not replace a 760 CCA factory battery with a lower-rated unit simply because both batteries fit the same tray. Match at least the electrical specification Ford calls for on your truck.

When Does an F150 Need an AGM Battery

An H6 or H7 label describes physical size. It does not automatically mean AGM.

AGM, or Absorbent Glass Mat, is a battery construction type designed to handle demanding electrical loads and repeated charge cycles better than many basic flooded batteries.

Ford’s own specifications show both battery technologies across the F-150 lineup.

The 2016 2.7L EcoBoost lists an AGM H6 at 760 CCA and an AGM H7 at 800 CCA for specified higher trims. Other 2016 engines list conventional BXT H6 and H7 batteries.

By the 2021 generation, Ford’s documentation lists AGM batteries such as BAGM-48H6-760 and BAGM-94RH7-800 across multiple engines.

If your original battery is AGM, replace it with the correct AGM equivalent rather than stepping down to a basic flooded battery.

EcoBoost owners comparing actual replacement products can also use our Ford F150 EcoBoost battery guide after identifying the correct group size.

How to Verify Your F150 Battery Size in 4 Checks

Use the chart to narrow the battery down, then make these four checks before ordering.

1. Read the Existing Battery Label

Start with the battery currently installed.

Look for markings such as:

• 48H6
• 94RH7
• 49H8
• Group 65
• BAGM
• BXT
• CCA rating
• Motorcraft part number

If the truck still has the correct original-spec battery, this is usually the fastest way to identify the required format.

2. Match the Engine and Trim

Do not stop at the model year when the chart shows more than one option.

A 2016 2.7L EcoBoost can have a different factory battery specification from another 2016 F-150. Ford also listed H7 batteries for certain King Ranch, Lariat, and Premium configurations.

3. Confirm the Ford Specification

Check your owner’s manual or Ford parts information using the VIN.

This matters most for newer F-150s because H6 and H7 options can overlap within the same year. The 2024 3.5L EcoBoost manual, for example, identifies a standard H6 AGM and optional H7 AGM battery.

4. Check the Tray and Terminals

Before installing a different group size, compare:

• Battery length
• Width and height
• Positive terminal position
• Negative terminal position
• Hold-down location
• Cable reach

A battery with more CCA is not an upgrade if it cannot be secured correctly.

What to Do After Replacing an F150 Battery

Installing the correct battery is only part of the job on newer F-150s because Ford uses a Battery Management System on applicable trucks.

Ford states that the system monitors battery condition and can reduce electrical loads when it detects excessive battery drain.

After battery replacement, Ford documentation says the Battery Management System can require eight hours of vehicle sleep time to relearn battery state of charge. During this period, the truck should remain switched off with the required doors or locks in the state specified by the manual.

On Ford models equipped with the supported battery sensor reset procedure, the sequence is:

1. Switch the ignition on without starting the engine.
2. Within 10 seconds, flash the high beams five times.
3. Press and release the brake pedal three times.
4. Watch for the battery warning lamp to flash three times as confirmation.

Use the procedure specified for your exact model year rather than assuming every F-150 generation handles battery replacement the same way.

If Auto Start-Stop remains unavailable after battery work, our Ford Auto Start Stop troubleshooting guide covers the wider system conditions that can disable the feature.

Which Ford F150 Battery Size Should You Buy

The safest replacement is the same verified group, battery technology, terminal layout, and minimum starting specification that Ford calls for on your exact truck.

Use this quick rule:

For a year-specific buying example, the site’s 2018 Ford F150 battery guide covers replacement choices for that model year.

A physically larger battery is not automatically better. Use H7 instead of H6 only where the battery tray, hold-down, terminal arrangement, and Ford application allow it.

8 Common Ford F150 Battery Size Questions

What Size Battery Does a Ford F150 Take

Ford F-150 battery sizes include Group 65, H6, H7, and H8, depending on the year and configuration. Many 2004 to 2014 trucks use Group 65, while H6 and H7 became common from the 2015 generation onward.

Does a Ford F150 Use H6 or H7

It can use either. Ford’s 2016 documentation lists H6 as the standard battery for several configurations and H7 for certain King Ranch, Lariat, and Premium trucks.

Is H7 the Same as Group 94R

Yes. H7 is commonly designated 94R in BCI-style North American battery catalogs. Interstate lists its batteries using the combined 94R/H7 designation.

Is H6 the Same as Group 48

Yes. Battery manufacturers commonly label this case format 48/H6. Interstate’s application documentation uses both designations together.

What CCA Battery Does a Ford F150 Need

It depends on the year, engine, and battery option. Verified Ford examples range from 610 CCA H6 batteries in some 2016 applications to an 850 CCA H8 AGM battery in the 2019 3.0L Power Stroke.

Does a Ford F150 Need an AGM Battery

Many newer F-150 applications do, but AGM should not be assumed from group size alone. Check the original battery and Ford specification because older H6 and H7 applications can also use conventional flooded Motorcraft BXT batteries.

Can I Install an H7 Instead of H6 in My F150

Only if the H7 is approved for the configuration and physically fits the battery tray and hold-down. H7 is roughly 1.4 inches longer than H6, so the two batteries are not physically identical.

Does the F150 Battery Need a Reset After Replacement

Applicable F-150 Battery Management Systems need to relearn the new battery state of charge. Ford documents an eight-hour sleep period and, on supported systems, a battery sensor reset procedure using five high-beam flashes followed by three brake-pedal presses.

The Right F150 Battery Comes Down to Exact Fitment

The Ford F150 battery size chart gets you to the correct group quickly, but the final decision should match your exact truck. Group 65 dominates many older F-150s, while H6 and H7 are common on newer generations. The 3.0L Power Stroke adds an H8 AGM exception.

Match the group size, AGM or flooded construction, terminal layout, and Ford’s minimum electrical rating. If two battery sizes appear for your year, check the engine, trim, existing battery label, and VIN before buying.

That final verification prevents the most common battery replacement mistake: buying a battery that technically appears in an F-150 catalog but does not match the electrical or physical configuration of your truck.
