The primary 12-volt battery is located in the engine compartment on the passenger side.
In most 2017 Transit 350 vans, Ford places the main 12V battery in the engine bay, secured in a plastic tray under a protective cover. The positive terminal is typically behind a red cap, and the battery is positioned for easy access from under the hood. Some configurations may include an auxiliary battery to support additional electrical systems; if your vehicle has two batteries, their second location varies by market and trim. Consult the owner's manual or a Ford dealer for the exact placement in your specific build.

How to locate and inspect the battery
To locate and inspect the battery, follow these basic steps. This guide focuses on common 2017 Transit 350 configurations and is suitable for routine checks and minor maintenance.
- Park the van on level ground, turn off the engine, and engage the parking brake. Open the hood to access the engine bay.
- Look on the passenger-side of the engine bay for a rectangular battery box sitting in a tray with a protective cover.
- Remove the protective cover to expose the terminals; identify the negative (usually black) and positive (usually red) posts.
- Inspect the terminals for corrosion, white/blue powder, or loose connections; if needed, clean with a stiff brush and a baking-soda solution, then re-tighten clamps following manufacturer torque specs.
