The 2007 Ford Five Hundred uses a standard 12-volt automotive battery. In most configurations, the replacement is a Group Size 65 flooded lead-acid battery, but exact size can vary by trim and equipment. Always verify with the battery label or the owner's manual before purchasing.
Battery size and specs
Understanding the right size and electrical specifications helps ensure reliable starts and electrical performance, especially through cold weather or long trips.
Group size and fit
To determine the exact group size you need, check the following indicators and references.
- Look at the side label on the current battery for the "Group Size" code (often 65, 75, or similar).
- Consult the 2007 Five Hundred owner's manual or Ford's official service data for your specific trim and region.
- Use a VIN-based parts lookup or ask a parts specialist to confirm the correct group size for your exact vehicle.
- Compare the physical dimensions and terminal layout to ensure the replacement will fit the tray and cable connections.
In practice, Group Size 65 is common for this model, but always confirm the exact size on your current battery or in the manual before buying.
Cranking power, capacity and battery type
Key electrical specs influence starting reliability and how long the battery will last between charges, especially in challenging conditions.
- Battery type: Standard flooded lead-acid is typical; AGM variants are compatible with some cars but should be verified for fit and charging system compatibility.
- Cold-cranking amps (CCA): Look for a value in the general range of 650–750 CCA for typical use; in very cold climates, higher CCA (700–800) can improve starting reliability.
- Reserve capacity (RC): A higher RC (roughly 100–140 minutes) helps sustained electrical load when the engine isn't running.
- Overall rating: Ensure the replacement meets or exceeds the original equipment’s CCA and RC specifications.
The exact CCA and RC depend on regional climate and the vehicle’s electrical load. When in doubt, opting for a battery that meets or exceeds the OEM spec is a sensible choice.
Installation and maintenance tips
Replacing a battery correctly protects electrical systems and ensures long life. Follow these practical steps to install a replacement safely.
- Park the car on a level surface, shift to Park (automatic) or Neutral (manual), and apply the parking brake.
- Disconnect the negative (-) battery terminal first, then the positive (+) terminal to avoid shorts.
- Remove the hold-down clamp and lift the old battery straight up out of the tray.
- Clean the battery tray and cable clamps; apply corrosion inhibitor if available.
- Place the new battery in the tray with the terminals in the same orientation as the old one; secure the hold-down clamp.
- Reconnect the positive (+) terminal first, then the negative (-); tighten terminals firmly but not overtight.
- Ensure all connections are clean, dry, and free of corrosion; start the engine to verify proper operation and reset any electronics if needed.
With proper installation, the new battery should provide reliable starts and steady electrical performance for years to come.
Summary
For most 2007 Ford Five Hundred models, the replacement battery is a 12-volt flooded lead-acid battery in Group Size 65, though some configurations may use a different group size. Always verify the exact size and specs on the current battery label or in the owner's manual, and choose a CCA and RC that suit your climate and driving needs. Proper installation and maintenance will help maximize battery life and reliability.
