2024 International MV Battery Size & Specifications

As an ASE-certified master technician who frequently works on commercial and medium-duty fleets, I know that keeping a work truck on the road is critical to your bottom line. The 2024 International MV is a powerhouse medium-duty truck, typically equipped with the Cummins B6.7 or L9 diesel engines. Cranking these massive diesels—and running the telematics, liftgates, and PTOs attached to them—requires a heavy-duty battery setup you can rely on.

Here is everything you need to know about the battery specifications, group size, and replacement procedures for the 2024 International MV.

Quick answer

• BCI group size: Group 31 (Commercial Heavy-Duty)
• CCA rating: 1,300 to 2,775+ combined CCA (Typically requires a minimum of 700–925 CCA per battery)
• Reserve capacity: Approximately 190–200 minutes per battery
• AGM vs flooded requirement: Flooded heavy-duty is factory standard; AGM is highly recommended as an upgrade for high-vibration and deep-cycle applications.
• Terminal layout: Threaded Stud (commonly 3/8-inch 16 UNC) centered on the top lid.
• Physical dimensions: 13.0" L x 6.8" W x 9.4" H (per battery)
• Multi-battery setup: Yes. Depending on the chassis configuration, the MV uses two or three Group 31 batteries wired in parallel to provide the massive amperage required for commercial diesel engines.

Replacement battery options

When replacing batteries in a 2024 International MV, you must replace all batteries in the bank at the same time. Mixing old and new batteries will cause the older units to drain the new ones, leading to premature failure. Here are some of the most reliable Group 31 replacement options for commercial trucks:

• Interstate Batteries: 31-MHD (Flooded, 950 CCA) – A fleet staple known for rugged reliability.
• Odyssey: ODX-AGM31 (AGM, 1150 CCA) – Extreme power and vibration resistance, ideal for severe-duty applications.
• ACDelco: 31-900CT (Flooded, 900 CCA) – Excellent OEM-grade replacement with heavy-duty grids.
• Optima: YellowTop D31T (AGM, 900 CCA) – Dual-purpose deep cycle and starting battery, great for trucks with high accessory loads.

AGM vs flooded — which does this vehicle need?

From the factory, most 2024 International MV chassis roll off the line with commercial-grade heavy-duty flooded lead-acid batteries. Flooded batteries are perfectly adequate for standard delivery and hauling routes.

However, you should upgrade to an Absorbent Glass Mat (AGM) battery if your truck operates in severe conditions. AGM batteries are sealed, maintenance-free, and significantly more resistant to the intense vibrations generated by medium-duty suspensions and diesel engines. Furthermore, if your truck runs a liftgate, inverter, or extensive auxiliary lighting while the engine is off, AGM batteries handle deep discharges far better than traditional flooded batteries.

Post-installation relearn / reset procedure

Unlike modern luxury passenger cars, commercial trucks like the 2024 International MV do not typically require a complex Battery Management System (BMS) relearn via an OBD scanner. However, after reconnecting the massive battery bank, follow these steps:

1. Turn the ignition key to the "ON" position (do not start the engine) and wait 30 seconds. This allows the ECM, TCM, and gauge cluster to initialize and run their sweep tests.
2. Start the engine and let it idle for 5–10 minutes to allow the alternator to stabilize voltage and the engine computer to relearn idle trims.
3. Check the dash for any persistent warning lights. Low voltage during the replacement can sometimes trigger ghost communication codes in the ABS or telematics modules, which will usually clear after a short test drive.
4. Reset the digital clock and any aftermarket radio or telematics settings.

Signs of a failing battery

In a multi-battery diesel setup, failing batteries can show unique symptoms:

• Slow, labored cranking: Especially evident on cold mornings when diesel glow plugs or grid heaters pull heavy amperage before the starter even engages.
• Clicking from the starter solenoid: The batteries may have enough voltage to power the dash, but lack the amperage to turn the heavy diesel starter.
• Erratic gauge behavior: Dashboard needles sweeping randomly or dimming headlights when auxiliary items (like the AC blower) are turned on.
• Sluggish PTO or liftgate operation: If your hydraulic systems sound like they are struggling when the engine is off or idling, your reserve capacity is likely compromised.

Common battery issues for this generation

The International MV is a workhorse, but its heavy-duty nature brings specific battery challenges. The most common issue is extreme vibration damage, which can physically crack the internal lead plates of flooded batteries over time. Another major culprit is parasitic draw from aftermarket upfitter equipment—such as GPS trackers, two-way radios, or poorly wired liftgate relays—that slowly drains the batteries over the weekend. Lastly, commercial environments inevitably lead to terminal corrosion. Ensure the threaded studs and parallel connecting cables are cleaned with a wire brush and coated in dielectric grease at every preventive maintenance interval.
