Understanding Your Ford Fusion’s Battery
Location and Type
The battery in your Ford Fusion is typically located under the hood, on the passenger side. It’s usually secured by a hold-down clamp or bracket. The battery type is usually a 12-volt lead-acid battery, but it’s always best to double-check your owner’s manual to confirm the specific specifications for your model year.
Battery Terminals
Your Ford Fusion’s battery has two terminals: a positive (+) terminal, which is usually red, and a negative (-) terminal, which is usually black. These terminals connect to the various electrical components in your car. It’s crucial to connect the terminals correctly to avoid damaging your car’s electrical system.
Safety First: Preparing for the Battery Change
Protective Gear
Before you begin, it’s essential to protect yourself from potential hazards. Wear safety glasses to shield your eyes from battery acid splashes, and wear gloves to prevent skin irritation.
Disconnect the Ground First
Always disconnect the negative terminal first when working with a car battery. This helps prevent accidental short circuits. Use a wrench to loosen the nut on the negative terminal and carefully remove the cable.
Ventilation
Car batteries produce explosive hydrogen gas. Work in a well-ventilated area to avoid inhaling these fumes. If possible, work outdoors.

Installing the New Battery
Clean the Battery Tray
Before installing the new battery, clean the battery tray with a wire brush to remove any corrosion or debris.
