Quick Answer
- BCI Group Size: Group 31 (typically two or three depending on configuration)
- CCA Rating: 925-1000 CCA per battery is recommended
- Reserve Capacity: 180-200 minutes (minimum) per battery
- AGM vs. Flooded: Flooded lead-acid is standard; AGM is a viable upgrade for increased durability and cycle life.
- Terminal Layout: Typically SAE posts with threaded studs for heavy-duty terminals.
- Physical Dimensions: Group 31 batteries are approximately 13" L x 6.8" W x 9.4" H.
- Dual-Battery Setup: The 2020 International MV typically uses a dual or triple Group 31 battery setup, wired in parallel, to provide the necessary cranking power for its diesel engine and to meet the electrical demands of various truck systems.
The 2020 International MV, a workhorse in the medium-duty truck category, relies on a robust electrical system, with its batteries being a critical component for reliable starting and powering accessories. Given the typical diesel engine and the electrical loads of modern commercial vehicles, understanding the correct battery specifications is paramount for preventing breakdowns and ensuring longevity.
Replacement Battery Options
Finding direct replacements for heavy-duty truck batteries often involves sourcing from commercial battery suppliers. While specific consumer-facing part numbers can be elusive, here are common equivalents for Group 31 batteries from popular brands:
- Interstate: MTZ-31 (Extreme AGM) or 31P-MHD (Flooded Lead-Acid)
- Optima: Optima does not typically produce batteries in the Group 31 size for heavy-duty truck applications. Their focus is more on passenger vehicles and light trucks with specific battery designs.
- DieHard: DieHard has commercial lines that may carry Group 31 batteries, often rebranded or sourced. Look for DieHard Commercial Group 31.
- Odyssey: PC2150ST (AGM) or 31-925 (AGM) - renowned for their high CCA and deep cycle capabilities.
- ACDelco: 31P-925 (Professional Series Flooded) or 31AGM (AGM).
Always verify part numbers and specifications with your supplier based on your vehicle
