2018 International MV Battery Size & Specs Guide

Quick answer

• BCI Group Size: Group 31 (typically two or three depending on configuration)
• CCA Rating: 925-1000 CCA per battery (minimum for reliable starting)
• Reserve Capacity: 175-200 minutes per battery
• AGM vs. Flooded: Flooded lead-acid is standard; AGM is a viable upgrade for increased vibration resistance and lifespan.
• Terminal Layout: Typically SAE post, top terminal.
• Physical Dimensions (Group 31): Approximately 13" L x 6.8" W x 9.4" H
• Dual/Triple Battery Setup: Yes, 2018 International MV trucks typically use a dual or triple battery setup for the 12V system, connected in parallel.

Replacement battery options

Choosing the right replacement battery for your 2018 International MV is crucial for reliable starting and electrical system operation. Due to the heavy-duty nature of this truck, you'll need robust batteries designed to withstand demanding conditions. Here are some popular options:

• Interstate: Look for their Group 31 commercial batteries, such as the Interstate MTZ-31 (Extreme AGM) or MTP-31 (Mega-Tron Plus flooded). Part numbers may vary by specific series and retailer.
• Optima: While Optima is known for high-performance batteries, their Group 31 offerings are more limited. If available, look for a YellowTop or RedTop in a Group 31 equivalent, though commercial truck applications often lean towards other brands for their larger Group 31 selection.
• DieHard: DieHard Commercial batteries in Group 31 are a strong contender. Check for models like the DieHard Platinum AGM Group 31 or DieHard Gold Group 31 flooded options. Specific part numbers will depend on the retailer.
• Odyssey: Odyssey offers excellent Group 31 batteries, known for their deep-cycle capabilities and durability, such as the Odyssey PC1220 or 31-PC2150. These are often premium AGM options.
• ACDelco: ACDelco offers maintenance-free and heavy-duty Group 31 batteries. Look for their Advantage or Professional series for your MV.

Always verify the specific part number and specifications with your supplier to ensure compatibility with your 2018 International MV.

AGM vs. flooded — which does this vehicle need?

The 2018 International MV typically comes equipped with flooded lead-acid batteries from the factory. These are a cost-effective and proven technology that performs well in most applications.

However, AGM (Absorbent Glass Mat) batteries are an excellent upgrade option for several reasons:

• Vibration Resistance: Commercial trucks experience significant vibration. AGM batteries are much more resistant to vibration damage due to their tightly packed internal components, leading to a longer lifespan.
• Maintenance-Free: AGM batteries are sealed and do not require watering, making them truly maintenance-free.
• Spill-Proof: The electrolyte is absorbed in glass mats, preventing spills and making them safer in various orientations.
• Faster Recharging: AGM batteries can often accept a charge more efficiently than flooded batteries.
• Better Cold Weather Performance: While good flooded batteries perform well, AGMs generally maintain performance better in extreme cold.

While AGM batteries have a higher upfront cost, their potential for increased durability and reduced maintenance can offset this over the long term, especially in a demanding commercial application like the International MV. If your truck operates in harsh conditions or you prioritize longevity and minimal maintenance, an upgrade to AGM is highly recommended.
