Quick Answer
- BCI Group Size: Group 31 (typically three or four batteries in a series/parallel configuration)
- CCA Rating: 925-1000 CCA per battery (minimum recommended)
- Reserve Capacity: 180-200 minutes per battery
- AGM vs. Flooded: Flooded lead-acid is standard; AGM is an upgrade providing better vibration resistance and deeper cycling capabilities.
- Terminal Layout: Typically SAE posts with stud terminals (for heavy-duty cables).
- Physical Dimensions: Group 31 batteries are approximately 13" L x 6.8" W x 9.4" H.
- Dual-Battery Setup: The M2 106 typically uses a multi-battery setup (3 or 4 batteries) wired in a series/parallel configuration to achieve 12V and high amperage capacity for starting and accessory loads.
Replacement Battery Options
- Interstate: Workhorse Group 31 (e.g., 31-MHD, 31-AGM7) - Specific part numbers vary by CCA and construction.
- Optima: Optima RedTop or YellowTop D31A/78 (AGM) - Often used for their deep-cycle and starting power blend, though typically a single Group 31 Optima may not match large commercial truck CCA requirements alone.
- DieHard: DieHard Platinum Group 31 (AGM) or DieHard Commercial Group 31 (Flooded) - Part numbers vary.
- Odyssey: Odyssey 31-PC2150S (AGM) - Known for high CCA and deep cycle capabilities.
- ACDelco: ACDelco Advantage or Professional Group 31 (Flooded or AGM options) - Part numbers vary.
(Always confirm the exact part number and specifications with the manufacturer or a reputable battery dealer based on your specific M2 106 configuration and needs.)
AGM vs. Flooded — Which Does This Vehicle Need?
The 2016 Freightliner M2 106, like most heavy-duty trucks, typically comes equipped from the factory with flooded lead-acid batteries. These are reliable, cost-effective, and perfectly capable of handling the starting and accessory demands of the truck under normal operating conditions. Flooded batteries require occasional maintenance, primarily checking and topping off electrolyte levels.
AGM (Absorbent Glass Mat) batteries are an excellent upgrade option for the M2 106. While not strictly
