A strong diesel-truck battery needs enough cranking output for the vehicle, a verified fit for its tray and terminals, and reserve capacity suited to its electrical load. The Crown Group 31 AGM Battery is the most directly truck-oriented option here: it is listed for commercial trucks and heavy-duty equipment and supplies 950 CCA and 100Ah per battery. Other choices offer different trade-offs, including 880 CCA in the OPTIMA DH7 YELLOWTOP and 930 CCA in the Odyssey ODX-AGM65.
This roundup compares ten AGM batteries using only their supplied specifications and compatibility details. Check your truck’s manual and existing battery label before choosing: group size, terminal arrangement, dimensions, and required battery count can rule out an otherwise appealing model.
The Crown Group 31 AGM Battery is the strongest fit for commercial diesel-truck use in this selection. Its listing specifically identifies commercial trucks and heavy-duty equipment, and each 12-volt battery provides 950 CCA and 100Ah. The pack includes four batteries, making it most relevant to fleet or multi-battery needs rather than a buyer seeking one replacement.
Confirm that Group 31 dimensions and the required battery configuration match your truck before ordering.

3. Odyssey ODX-AGM65
- Voltage: 12 V
- Dimensions: 7.16"D x 11.83"W x 7.43"H
- Weight: 60 lb
Best for: High-cranking Group 65 power.
Why it ranks #3: Its Group 65 design delivers 930 CCA and 135 minutes of reserve capacity, although the listing identifies passenger cars rather than trucks.
With 930 cold cranking amps and 1,750 PHCA, the Odyssey ODX-AGM65 emphasizes strong starting output in a Group 65 AGM package.

4. OPTIMA 34/78 REDTOP
- Voltage: 12 V
- Dimensions: 6.88"D x 10"W x 7.81"H
- Weight: 38.8 lb
Best for: Truck-focused starting power.
Why it ranks #4: The listing names trucks, and its 800 CCA, dual SAE and GM posts, and starting-focused design make it a relevant single-battery candidate.
An 800 CCA rating and explicit truck compatibility make the OPTIMA 34/78 RedTop a straightforward starting-battery option for diesel-truck owners. Its dual SAE and GM posts provide two listed terminal styles, while SpiralCell technology and a 100-minute reserve capacity add useful context beyond its primary starting role.
The RedTop is described as a high-power cranking battery for harsh weather, linking its 800 CCA rating to the stated goal of reliable ignition. Its 100-minute reserve capacity provides a specified reserve measure, while faster charging capabilities may matter in a vehicle’s charging workflow. Dual SAE and GM posts give connection options, but the 38.8-pound, roughly 10-by-6.88-by-7.81-inch package still requires compatible tray dimensions and cable reach.
- 800 CCA starting rating
- Listed compatible with trucks
- Dual SAE and GM posts
- 100-minute reserve capacity
- Its 100-minute reserve capacity is shorter than the YellowTop D34/78’s 120 minutes.
Skip it if you need more listed reserve for accessory cycling; the OPTIMA YellowTop D34/78 specifies 120 minutes and dual-purpose use.
This RedTop fits buyers prioritizing a truck-listed starting battery with 800 CCA and dual terminal styles. It is presented chiefly for starting, so consider the YellowTop D34/78 if accessory cycling and longer listed reserve matter more.

5. Interstate MTX-65 AGM
- Voltage: 12 V
- Dimensions: 12.06"D x 7.56"W x 7.44"H
- Weight: 45 lb
Best for: Group 65 AGM truck option.
Why it ranks #5: Listed as compatible with trucks and SUVs, this Group 65 AGM provides 750 CCA and 68Ah for buyers whose vehicle accepts its size.
The Interstate MTX-65 combines a Group 65 designation with 750 CCA and 68Ah capacity, giving truck owners concrete fit and output details to assess. Its absorbed glass mat design is identified for start-stop vehicles and accessory power, and the listing includes trucks among compatible vehicle types.
Interstate says its pure-lead MTX AGM packs more lead into the battery, connecting its construction to the stated aim of long service life for start-stop use. The 750 CCA rating addresses starting requirements, while 68Ah indicates listed capacity for powering accessories. Its 12.06-by-7.56-by-7.44-inch dimensions and 45-pound weight are relevant to installation and handling. The product page directs buyers to a compatibility guide to verify fit.
- 750 CCA rating
- 68Ah listed capacity
- Group 65 size
- Vehicle compatibility includes trucks
- The supplied listing gives no reserve-capacity figure.
Skip it if you require a published reserve-capacity figure before choosing; the OPTIMA RedTop 34/78 lists 100 minutes.
Consider this Interstate for a truck whose requirements call for Group 65, 750 CCA, and AGM construction. Use the linked compatibility guide and verify tray and terminal fit; the supplied details do not state reserve capacity.

6. ACDelco Gold 48AGM
- Voltage: 12 V
- Dimensions: 7.5"D x 11.9"W x 7.6"H
- Weight: 45.5 lb
Best for: AGM start-stop truck use.
Why it ranks #6: The listing identifies truck compatibility and supplies a 12-volt Group 48 AGM with a 36-month free replacement and limited warranty.
A leak- and spill-proof AGM design gives the ACDelco Gold 48AGM a practical advantage for truck owners seeking a sealed 12-volt battery. Its high-density negative paste and Silver Calcium alloy support performance and cycle life, while the listed truck compatibility makes it a candidate for vehicles requiring Group 48.
The robust envelope separator has a puncture-resistant back, and its allowance for increased acid circulation helps prevent shorts while supporting cooling. A calcium-lead positive grid maximizes conductivity and allows low resistance, connecting the design to efficient electrical flow. ACDelco also identifies this AGM line for start-stop applications and describes it as charge-receptive. At 45.5 pounds and 11.9 by 7.5 by 7.6 inches, it needs space and lifting capacity for installation.
- 12-volt AGM battery listed as compatible with trucks
- Leak- and spill-proof absorbed glass mat design
- Silver Calcium alloy supports cycle life
- Separator promotes acid circulation and helps prevent shorts
- Group 48 dimensions and terminals may not suit every diesel truck.
Skip it if you need a Group 31 commercial battery or a four-battery fleet pack; this is a single Group 48 unit.
A truck owner needing a single Group 48 AGM for a start-stop application should consider this ACDelco. Its listed dimensions, weight, and vehicle fit still need to match the truck’s battery tray and electrical requirements.

7. OPTIMA D34/78 YELLOWTOP
- Voltage: 12 V
- Dimensions: 6.88"D x 10"W x 7.81"H
- Weight: 43.5 lb
Best for: Accessory-heavy truck starting.
Why it ranks #7: Its 750 CCA, 120-minute reserve, and dual-purpose cycling design may suit accessory-heavy use, but its listed vehicle type is passenger car.
Dual-purpose construction is the defining feature of the OPTIMA YellowTop D34/78: it pairs cranking power with cycling capability for vehicles running accessories. The manufacturer identifies trucks with winches, high-demand audio systems, and commercial vehicles as use cases, while dual SAE and GM terminals offer two listed connection styles.
Its 750 CCA rating and 120-minute reserve capacity combine starting capability with a stated reserve for ongoing electrical loads. OPTIMA’s SpiralCell technology uses 99.99% pure lead and is described as delivering more power than conventional flat-plate batteries; the product also lists faster charging capabilities. The 43.5-pound battery measures 10 by 67⁄8 by 7 13/16 inches, so confirm tray clearance and terminal access before installation.
- Dual-purpose starting and cycling capability
- 750 CCA rating
- 120-minute reserve capacity
- Dual SAE and GM terminals
- At 750 CCA, its listed cranking rating is lower than the OPTIMA RedTop’s 800 CCA.
Skip it if you prioritize the higher listed cranking rating over accessory cycling; the OPTIMA 34/78 RedTop lists 800 CCA.
Choose this YellowTop for a diesel truck with winches, high-demand audio, or other accessory loads where dual-purpose operation matters. Check the 10-inch length and dual-terminal arrangement against the truck’s battery space and cables.

8. ACDelco Gold 94RAGM
- Voltage: 12 V
- Dimensions: 6.9"D x 12.4"W x 7.5"H
- Weight: 51.6 lb
Best for: High-cycling Group 94R AGM.
Why it ranks #8: This 12-volt AGM has a 36-month free replacement and limited warranty, but its listing does not establish truck compatibility or provide CCA.
The ACDelco Gold 94RAGM combines a high-density negative paste with a Silver Calcium alloy, features tied in the listing to performance and cycle life. Its 12-volt AGM construction is described as charge-receptive and suited to start-stop applications, making it worth assessing when a truck calls for Group 94R.
A calcium-lead positive grid maximizes conductivity and allows low resistance, while the puncture-resistant envelope separator supports increased acid circulation and helps prevent shorts. Together these details connect the battery’s internal construction to electrical flow and separation protection. ACDelco describes its AGM design as leak- and spill-proof. The unit measures 12.4 by 6.9 by 7.5 inches and weighs 51.6 pounds; the listing does not identify a compatible vehicle type.
- Group 94R AGM designation
- High-density negative paste supports performance
- Silver Calcium alloy supports cycle life
- Leak- and spill-proof AGM design
- The supplied vehicle-compatibility field does not identify trucks or another vehicle type.
Skip it if you need truck compatibility explicitly stated; the ACDelco Gold 48AGM listing identifies trucks as compatible.
This ACDelco is an option for buyers whose battery requirements specify Group 94R and who value AGM construction for start-stop use. The listing does not establish truck compatibility, so verify the application before selecting it.

9. Goodyear 48-H6-AGM
- Voltage: 12 V
- Dimensions: 10.75"D x 6.87"W x 7.5"H
- Weight: 46.7 lb
Best for: Flexible-position Group 48 AGM.
Why it ranks #9: It offers 760 CCA, 70Ah, and 120 minutes of reserve, but the listed compatible vehicle type is ATV rather than truck.
Multiple-position mounting, except upside down, is the Goodyear 48-H6-AGM’s clearest installation feature. Its Group 48 size, 760 CCA, and 70Ah capacity provide useful specifications for comparison, while the 120-minute reserve capacity adds a stated measure of power availability beyond starting.
The 760 CCA rating is presented for starts in varied weather, and the 120-minute reserve capacity offers a stated buffer for electrical loads. The product’s flexible mounting positions, with upside-down installation excluded, can help when vehicle layout constrains placement. It measures 10.75 by 6.87 by 7.5 inches and weighs 46.7 pounds. Although its title identifies Group 48, the supplied compatibility field lists ATV, so truck fit is not established.
- 760 CCA rating
- 70Ah listed capacity
- 120-minute reserve capacity
- Multiple-position mounting except upside down
- The supplied vehicle-compatibility field lists ATV, not truck.
Skip it if you need truck compatibility explicitly listed; the Interstate MTX-65 specifies compatibility with trucks and a Group 65 size.
This Goodyear suits buyers comparing Group 48 dimensions, reserve capacity, and flexible mounting options. Its supplied compatibility field identifies ATV rather than truck, so treat diesel-truck fit as unconfirmed and check the application requirements.

- Voltage: 12 V
- Dimensions: 10.94"D x 6.88"W x 7.48"H
- Weight: 12 lb
Best for: Group 48 sealed AGM.
Why it ranks #10: Although its Group 48 battery supplies 760 CCA and 70Ah, its listed compatible vehicle type is golf cart, making truck fit least established.
A 760 CCA rating paired with 70Ah capacity gives the Mighty Max MM-H6 concrete starting and capacity figures in a Group 48 package. Its sealed, spill-proof AGM construction and 120-minute reserve capacity may suit buyers seeking a maintenance-free battery with a stated reserve for electrical demands.
The battery’s 760 CCA rating is presented for starting in any weather, while its 120-minute reserve capacity supports longer run times according to the listing. Sealed, spill-proof AGM construction avoids liquid-spill concerns, and the product also specifies deep-discharge recovery. At 10.94 by 6.88 by 7.48 inches, it offers Group 48 dimensions for fit checks. The supplied vehicle-compatibility field says golf cart, not truck, so truck application is not established.
- 760 CCA rating
- 70Ah listed capacity
- 120-minute reserve capacity
- Sealed, spill-proof AGM design
- The supplied vehicle-compatibility field lists golf carts, not trucks.

View on AmazonAvoiding Group-Size and Terminal Mismatches
A battery’s group number and terminal layout must match the truck; CCA alone cannot establish fit. These listings span Group 31, Group 65, Group 48, Group 94R, and 34/78 formats, with different dimensions and terminal details. For example, the Crown Group 31 AGM measures 13 inches long by 6.77 inches wide by 8.44 inches high, while the OPTIMA 34/78 REDTOP lists dual SAE and GM posts.
Those differences matter because a battery that cannot sit securely or connect to the existing cables is not a usable upgrade, regardless of its cranking figure. Check the vehicle manual, the current battery label, tray clearance, cable reach, and terminal position before buying.
Compatibility information also varies in reliability: some listings explicitly mention trucks, while others name passenger cars, ATVs, or golf carts. Treat an unlisted truck fit as something to verify, not an assumption.
Starting Power Versus Reserve Capacity
A high CCA figure and a large reserve-capacity figure describe different needs, so one should not be used as a substitute for the other. CCA is the listed cold-cranking measure, while reserve capacity and amp-hours give additional context about stored power and sustained use. In this selection, the Crown Group 31 AGM lists 950 CCA and 100Ah; the Odyssey ODX-AGM65 lists 930 CCA and 135 minutes of reserve; and the OPTIMA DH7 YELLOWTOP lists 880 CCA, 80Ah, and 155 minutes of reserve.
The OPTIMA D34/78 YELLOWTOP instead offers 750 CCA and 120 minutes of reserve. A buyer prioritizing listed cranking output may prefer a higher CCA figure, while a truck running accessories may value reserve and dual-purpose capability.
Verify the truck maker’s required ratings and battery configuration before comparing these figures across different sizes.
How to Choose a Diesel-Truck Battery
Cold-Cranking Amps
Look for a CCA rating that meets or exceeds the requirement in your truck’s manual, especially if cold starts are a concern. Listed ratings range from 750 CCA on the OPTIMA D34/78 YELLOWTOP to 950 CCA on each Crown Group 31 AGM; the Odyssey ODX-AGM65 lists 930 CCA, while the OPTIMA DH7 YELLOWTOP lists 880 CCA. These values are not a guarantee of fit or performance in a particular truck, and the product data does not establish a universal minimum for diesel engines.
Buyers replacing a battery in a cold-weather truck should compare the manual’s requirement against the label, while those considering lower listed CCA should confirm the rating is adequate for their exact vehicle.
Capacity and Reserve
Choose capacity and reserve according to the truck’s electrical demands and how much time it may need to support them. Among products with capacity stated, the Crown Group 31 AGM lists 100Ah, the OPTIMA DH7 YELLOWTOP 80Ah, and the Interstate MTX-65 68Ah; reserve figures include 155 minutes for the DH7, 135 minutes for the Odyssey ODX-AGM65, and 120 minutes for several models. Not every listing supplies both measures, so missing figures should not be treated as zero or directly compared.
A commercial or accessory-heavy application may favor a model with explicitly stated higher capacity or reserve, while a standard replacement buyer should first follow the vehicle’s original specification.
Size, Terminals, and Vehicle Fit
Confirm the specified group size, dimensions, terminal arrangement, and stated vehicle compatibility before selecting a battery. The listed formats include Group 31, Group 65, Group 48, Group 94R, and 34/78; dimensions vary accordingly. The OPTIMA 34/78 REDTOP specifies dual SAE and GM posts, while the Odyssey ODX-AGM65 specifies a right-side negative terminal and Group 65 posts.
Vehicle-fit evidence also differs: Crown is identified for commercial trucks and heavy-duty equipment, and several listings name trucks, but others specify passenger cars, an ATV, or a golf cart. Buyers should favor a listing that matches their truck’s exact requirements and verify any model whose stated vehicle type does not confirm truck compatibility.
Which Battery Fits Your Diesel Truck?
For a commercial truck or fleet application that uses Group 31 batteries, choose the Crown Group 31 AGM: it is explicitly listed for commercial trucks and supplies 950 CCA and 100Ah per battery, but the four-pack may not suit a single replacement. For a truck whose verified fit is Group 65 and where reserve capacity matters, consider the Odyssey ODX-AGM65, with 930 CCA and 135 minutes of reserve, while checking its passenger-car compatibility listing. If your truck needs dual-purpose operation and substantial reserve, the OPTIMA DH7 YELLOWTOP lists 880 CCA and 155 minutes.
For a truck-specific starting option with dual SAE and GM posts, consider the OPTIMA 34/78 REDTOP. In every case, match the required size, terminals, ratings, and battery count to the truck manual before purchase.

Frequently Asked Questions
How do I confirm the correct battery group size and terminal layout for my diesel truck?
Check the truck manual or existing battery for the required group size, terminal positions, and post types, then compare those details with the listing. Also confirm dimensions and required battery count. If the vehicle’s configuration is unclear, have a qualified technician verify fit before ordering; matching the group label alone may not confirm compatibility.
Should a diesel truck use one battery or a matched pair?
Use the battery count specified for your truck; some configurations require one battery, while others use two. For a dual-battery setup, confirm the required type and ratings for both positions and follow the manufacturer’s replacement guidance. Do not assume a four-battery pack is appropriate just because the truck uses multiple batteries.
Can an AGM replacement be used with my truck’s charging system?
Use an AGM battery only if the truck’s manufacturer permits AGM and the charging system is compatible with that battery type. Check the owner’s manual or consult a qualified technician before switching chemistries. Also verify group size, terminal layout, ratings, and battery count; matching the physical fit alone does not establish charging compatibility.
How should I compare CCA and reserve capacity?
Start with the minimum ratings required by your truck, then compare listings that meet them. The products here show different CCA figures, and some provide reserve-capacity figures, but not every listing includes both. Treat those numbers as comparison points, not proof of fit; confirm the truck’s requirements before choosing.
What should I check before choosing a multi-battery pack?
Confirm how many batteries your truck requires, whether they must be matched, and whether the listed group size and terminals fit. The Crown Group 31 listing is a four-pack, making it relevant to fleet or multi-battery needs, but it may not suit a single replacement. Verify the truck’s configuration before ordering.
Final Words
Start with the truck manual: confirm battery group, terminal layout, required ratings, chemistry compatibility, and battery count. For commercial use that calls for Group 31, the Crown pack is the strongest fit in this selection, though its four-battery configuration may be excessive for a single replacement. For other trucks, choose only a listed option that matches verified requirements; consider the Odyssey or OPTIMA alternatives only where their fit and intended use are appropriate.
