2019 Ford Transit Battery Size & Group

Quick answer

• BCI Group Size: H6 (also known as Group 48) or H7 (Group 94R) for gasoline engines, and dual Group 31 for diesel models.
• Cold Cranking Amps (CCA): 760-850 CCA for the primary H6/H7 battery. Diesel setups will have higher ratings.
• Reserve Capacity (RC): Approximately 140-160 minutes.
• AGM vs. Flooded: AGM (Absorbent Glass Mat) is required for most models, especially those with start-stop technology.
• Terminal Layout: Right-hand positive (standard for most European and domestic vehicles).
• Physical Dimensions (H6/Group 48): Roughly 10.9" L x 6.9" W x 7.5" H.
• Dual-Battery Setup: Diesel models feature a dual-battery setup for increased starting power and to handle the demands of the glow plugs.

Replacement battery options

• Interstate: MTX-48/H6 or MTX-94R/H7
• Optima: DH6 YELLOWTOP
• DieHard: Platinum AGM H6 or H7
• Odyssey: Performance Series ODP-AGM48 H6
• ACDelco: 48AGM or 94RAGM

AGM vs flooded — which does this vehicle need?

The 2019 Ford Transit, particularly models equipped with the start-stop feature, requires an AGM (Absorbent Glass Mat) battery. AGM batteries are designed to handle the frequent deep discharges associated with start-stop systems and provide the higher electrical loads demanded by modern vehicles. They are also more resistant to vibration and are spill-proof, making them a safer and more durable option. While a standard flooded battery might fit, it will have a significantly shorter lifespan and may not provide reliable performance.

Post-installation relearn / reset procedure

After replacing the battery on a 2019 Ford Transit, a battery relearn procedure is necessary to ensure the vehicle's charging system operates correctly. The Battery Monitoring System (BMS) must be reset to tell the powertrain control module (PCM) that a new battery has been installed. This allows the system to adjust the charging strategy for the new battery, extending its life and ensuring optimal performance. The reset procedure typically requires a diagnostic scan tool and should be performed by a qualified technician. Driving the vehicle for several hours may also allow the system to relearn, but the scan tool method is the most reliable.

Signs of a failing battery

• Slow engine crank: The engine turns over sluggishly when you try to start it.
• Warning lights: The battery or check engine light may illuminate on the dashboard.
• Dimming lights: Headlights and interior lights may dim, especially at idle.
• Electrical issues: Malfunctions with the radio, power windows, or other electrical accessories.
• Visible corrosion: A white, powdery substance around the battery terminals.
• Swollen battery case: The battery case appears bloated or misshapen.

Common battery issues for this generation

The 2015-2019 generation of the Ford Transit is generally reliable, but some owners have reported premature battery failure, especially on models with the start-stop system. The frequent cycling of the battery can lead to a shorter lifespan if the vehicle is not driven long enough to fully recharge the battery. Additionally, parasitic draws from aftermarket accessories or faulty modules can drain the battery, leading to starting issues.
