• Battery Capacity: 100 amp hours
• Weight: 76 lb
• Compatible with Vehicle Type: Commercial Truck, Heavy-duty equipment…

Best for: Heavy-duty single-battery truck use.

Why it ranks #1: Built for commercial trucks and heavy-duty equipment, it pairs 950 CCA and 100Ah capacity with sealed AGM construction in a single-battery package.

A 950-CCA rating gives the Crown CRV31S its clearest advantage, supporting strong starting performance in commercial trucks and heavy-duty equipment. Its 100Ah capacity also provides deep reserve power, while the sealed, spill-proof AGM construction avoids routine battery maintenance. This is a single Group 31 battery for demanding applications.

• Battery Capacity: 100 amp hours
• Weight: 76 lb
• Compatible with Vehicle Type: Commercial Truck, Heavy-duty equipment…

Best for: Four-battery commercial fleet supply.

Why it ranks #2: The same commercial-use 950 CCA, 100Ah AGM battery comes as four units, making this listing the largest included quantity for fleet requirements.

Four Crown CRV31S batteries in one listing make this option immediately relevant to fleet or commercial buyers needing several Group 31 units.

Best for: Two-battery commercial service needs.

Why it ranks #3: Two commercial-use Crown AGM batteries provide 950 CCA and 100Ah each, a useful listed quantity for buyers replacing batteries in pairs.

The two-battery quantity makes this Crown CRV31S listing a practical match for commercial operators replacing or stocking a pair of Group 31 units. Each sealed AGM battery supplies 950 CCA and 100Ah, and Crown lists compatibility with commercial trucks, heavy-duty equipment, and industrial applications.

Two units provide a pair for commercial or fleet use, with 950 CCA per battery for starting and 100Ah capacity per battery for reserve power. The sealed, spill-proof AGM design is maintenance-free, limiting routine upkeep across both units. Crown also identifies vibration resistance for heavy-duty service. Each battery measures 13 by 6.77 by 8.44 inches and weighs 76 pounds, so buyers can plan compartment space and safe handling before installation.

#5 · Highest CCA

5. Odyssey ODX-AGM31M

• Weight: 79 lb
• Compatible with Vehicle Type: Passenger Car

Best for: High-cranking power and long reserve.

Why it ranks #5: Its listed 1,150 CCA exceeds the other stated cranking figures, with 205 minutes reserve capacity, though its vehicle type is listed as passenger car.

A 1,150-CCA rating gives the Odyssey ODX-AGM31M a powerful starting specification, paired with 205 minutes of reserve capacity for extended reserve needs. Its Group 31 terminals include brass SAE posts and stainless-steel stud terminals. This is a 12V AGM battery with a listed right-side negative terminal location.

The 1,150 CCA and 2,150 PHCA figures emphasize starting output, while the 205-minute reserve capacity supports power availability beyond the initial start. Brass SAE posts and stainless-steel stud terminals offer two specified connection styles, and the right-side negative terminal location is useful to check during installation planning. Odyssey also describes deep-cycling capability up to 400 cycles at 80% depth of discharge. The listing identifies passenger-car compatibility, so commercial fit needs consideration.

Skip it if you need explicitly listed commercial-truck compatibility; the Crown CRV31S is listed for commercial trucks and equipment.

6. U.S. Battery US31DCXC2

• Battery Capacity: 130 milliamp hours
• Weight: 66 lb

Best for: Flooded deep-cycle capacity.

Why it ranks #6: The title identifies 130Ah and Group 31 size, offering more stated capacity than the 100Ah options, but this is a flooded deep-cycle battery.

The U.S. Battery US31DCXC2 lists 130Ah capacity, setting it apart for buyers focused on deep-cycle energy rather than a published cranking rating. It uses flooded lead-acid chemistry in a Group 31, 12V format. The supplied information identifies deep-cycle use but does not provide a CCA figure.

Its stated 130Ah capacity and flooded deep-cycle chemistry point toward applications where stored energy and cycling are central considerations. The 12V rating and Group 31 size identify its electrical and form-factor category, while the listed dimensions—13 by 6.73 by 9.56 inches—help with space planning. Flooded chemistry is an important distinction from sealed AGM options in this roundup; buyers should account for that construction when deciding whether it suits their operating and maintenance setup.

Skip it if you need a published CCA rating for truck starting; the Crown CRV31S lists 950 CCA.

Consider the US31DCXC2 when a Group 31 flooded deep-cycle battery and its stated 130Ah capacity match the application. If cold-start performance is a priority, note that this listing provides no CCA figure.

7. Mighty Max MM-G31 Chevrolet

• Battery Capacity: 100 amp hours
• Weight: 57.6 lb
• Compatible with Vehicle Type: Passenger Car

Best for: Chevrolet LCF 3500 application listing.

Why it ranks #7: This sealed AGM Group 31 battery lists 900 CCA and 100Ah and names Chevrolet LCF 3500 compatibility, but its vehicle type field says passenger car.

A named Chevrolet LCF 3500 17 replacement application makes this Mighty Max MM-G31 listing easier to evaluate for owners of that truck. It pairs 900 CCA with 100Ah capacity and 140-minute reserve capacity in a sealed, spill-proof AGM battery. The listing also describes deep-discharge recovery.

The Chevrolet LCF 3500 17 compatibility statement provides a specific vehicle application, while the 900-CCA rating addresses starting output and 100Ah capacity provides reserve context. A 140-minute reserve capacity and listed deep-discharge recovery support evaluation for ongoing power demands. The sealed, spill-proof AGM construction avoids liquid-spill concerns. Dimensions are 12.88 by 6.75 by 9.5 inches; compare these and the stated vehicle application with the installation requirements before choosing.

Skip it if you need a listing explicitly identifying commercial trucks as compatible; the Crown CRV31S does so.

#8

8. Mighty Max MM-G31

• Battery Capacity: 100 amp hours
• Weight: 57.6 lb
• Compatible with Vehicle Type: Passenger Car

Best for: Reserve-focused AGM starting battery.

Why it ranks #8: It offers sealed AGM construction, 900 CCA, 100Ah, and 140-minute reserve capacity, but its listed compatible vehicle type is passenger car.

A 140-minute reserve capacity is the Mighty Max MM-G31's defining practical feature, supporting longer run times when power demand continues beyond engine starting. It pairs that reserve with 900 CCA and 100Ah capacity in a sealed, spill-proof AGM battery. Its listed vehicle compatibility is passenger cars.

The 900-CCA rating supports starting power, while 100Ah capacity and 140 minutes of reserve capacity speak to sustained power needs. Mighty Max also describes high discharge output and deep discharge recovery, which can help maintain steady power through demanding use. The sealed, spill-proof AGM design avoids liquid-spill concerns. However, the listed compatible vehicle type is passenger car, so commercial-truck buyers should weigh that stated fit rather than infer truck compatibility from the Group 31 size.

Skip it if you need listed commercial-truck compatibility; the Crown CRV31S is explicitly listed for commercial trucks.

This MM-G31 suits buyers prioritizing a sealed AGM battery with 900 CCA and 140-minute reserve capacity. Its listing identifies passenger cars, so commercial-truck shoppers should check application requirements rather than rely on Group 31 sizing alone.

• Compatible with Vehicle Type: Passenger Car

Best for: Generac RD040 replacement application.

Why it ranks #9: This 900 CCA, 100Ah AGM battery is identified as a Generac RD040 replacement, not as a commercial truck battery.

Compatibility with the Generac RD040 generator model is this Mighty Max MM-G31 listing's clearest application-specific detail. The 12V battery has 100Ah capacity, 900 CCA, and 140-minute reserve capacity. Its sealed, spill-proof AGM construction adds deep-discharge recovery, though the supplied vehicle-type specification says passenger car.

The explicit RD040 replacement compatibility gives generator owners a named application to evaluate, while 100Ah capacity and 140-minute reserve capacity offer power-storage context. Its 900 CCA rating specifies starting output, and the AGM design is sealed and spill-proof. Mighty Max also lists high discharge output and deep-discharge recovery. The product dimensions are 12.88 by 6.75 by 9.5 inches; check the generator's battery requirements against those details and the model-specific compatibility statement.

Skip it if you need a battery listing focused on a commercial truck; the Crown CRV31S is explicitly listed for commercial trucks.

This MM-G31 listing is aimed at buyers replacing a battery in the named Generac RD040 application and seeking sealed AGM construction with 100Ah capacity. Verify the stated model and dimensions against the intended installation.
