2022 Ford Transit Battery Size & Group

Quick Answer

• BCI Group Size: H7/94R (for gasoline engines), Group 31 (for diesel engines)
• CCA Rating: 800 CCA (gasoline), 900-1000 CCA (diesel)
• Reserve Capacity: 140-160 minutes (gasoline), 180-200 minutes (diesel)
• AGM vs. Flooded: AGM recommended for all Transit models due to sophisticated electrical systems and start-stop technology (if equipped). Diesel models require AGM or enhanced flooded (EFB) to handle higher demands.
• Terminal Layout: Top post, typically with positive on the right.
• Physical Dimensions:
  • H7/94R: Approximately 12.4" L x 6.9" W x 7.5" H
  • Group 31: Approximately 13" L x 6.8" W x 9.4" H
• Dual-Battery Setup: Diesel models come standard with a dual-battery setup (two Group 31 batteries).

Replacement Battery Options

• Interstate: MTZ-94R (H7/94R), Group 31AGM (for diesel)
• Optima: YellowTop H7 (94R) (for gasoline), YellowTop Group 31 (for diesel)
• DieHard: Platinum AGM H7 (for gasoline), Platinum AGM Group 31 (for diesel)
• Odyssey: ODP-AGM94R (H7/94R), ODP-AGM31 (for diesel)
• ACDelco: 94RAGM (H7/94R), Group 31 AGM (for diesel)

AGM vs. Flooded — Which Does This Vehicle Need?

The 2022 Ford Transit, regardless of engine type, primarily benefits from and often requires an Absorbed Glass Mat (AGM) battery. Gasoline models often feature advanced electrical systems, including start-stop technology, which places greater demands on the battery. Traditional flooded lead-acid batteries are not designed to handle the frequent deep discharges and recharges associated with these systems, leading to a significantly shorter lifespan. AGM batteries, with their robust construction and ability to cycle deeply without damage, are the ideal choice.

For 2022 Ford Transit diesel models, an AGM battery is essentially mandatory. Diesel engines require a much higher cranking power to start, especially in cold weather. Furthermore, the dual-battery setup in diesel Transits is designed to deliver consistent, high-amperage power. Flooded batteries would quickly degrade under these conditions. Some manufacturers may offer Enhanced Flooded Batteries (EFB) as an alternative for start-stop systems, but for the heavy-duty demands of a Transit diesel, AGM is the superior and recommended option.

Post-Installation Relearn / Reset Procedure

After replacing the battery in your 2022 Ford Transit, it's crucial to perform a Battery Monitoring System (BMS) reset. This procedure recalibrates the vehicle's charging system to the new battery, ensuring optimal charging and battery life. Failing to do so can lead to overcharging or undercharging, prematurely shortening the new battery's lifespan.

The BMS reset procedure typically involves:

1. Ensuring the new battery is fully charged.
2. Turning off the ignition and closing all doors.
3. Turning on the headlights for at least 10 seconds. This helps to fully discharge any residual power in the system.
4. Turning off the headlights.
5. With the ignition off, disconnect the negative battery terminal for at least 15 minutes. Some sources suggest a longer period, up to an hour, to ensure all modules reset.
6. Reconnect the negative battery terminal.
7. Drive the vehicle for at least 10 miles with several engine off/on cycles to allow the BMS to re-learn the battery's state of charge. During this time, you may notice some features, like start-stop, not working immediately.

Alternatively, a more precise reset can often be performed using a diagnostic scan tool that can directly access the vehicle's Body Control Module (BCM) and initiate a BMS reset function.

Signs of a Failing Battery

Recognizing the signs of a failing battery can help you avoid being stranded. Here are common indicators:

• Slow Engine Crank: The most common sign. If your engine cranks slowly or struggles to turn over, it's often a sign of a weak battery.
• Dim Headlights or Interior Lights: When the engine is off, dim lights can indicate a low state of charge or a failing battery.
• Warning Lights: A battery warning light on your dashboard is a clear indication of an issue.
• Corrosion on Terminals: Greenish or white powdery substance on battery terminals can hinder connections and indicate a leaking battery.
• Swollen Battery Case: If the battery case appears swollen or bulging, especially on the sides, it's a sign of internal damage and that the battery needs to be replaced immediately.
• Foul Odor: A sulfuric or rotten egg smell around the battery indicates a leak or internal damage.
• Clicking Noise on Start-up: A rapid clicking sound when trying to start the vehicle can mean insufficient power to engage the starter motor.

Common Battery Issues for This Generation

Owners of the 2022 Ford Transit, particularly those with advanced electrical systems, may encounter a few common battery-related issues:

• Premature Battery Failure (Flooded Batteries): If a non-AGM battery is installed in a vehicle designed for AGM (especially those with start-stop), its lifespan will be significantly reduced due to the stress of frequent deep cycling.
• BMS Malfunctions: Issues with the Battery Monitoring System can lead to incorrect charging, either overcharging or undercharging, which can damage the battery.
• Parasitic Draws: Aftermarket accessories or sometimes even factory components can draw power when the vehicle is off, leading to a dead battery if the vehicle sits for extended periods. The Transit's complex electrical system can sometimes make pinpointing these draws challenging.
• Cold Weather Performance: While diesel engines inherently require more power to start, a weak battery in cold weather will exacerbate starting difficulties. Ensuring your diesel Transit has robust, fully charged AGM batteries is critical for cold starts.
