The 2010 Ford Fusion uses a standard 12-volt automotive battery for starting the engine and powering the electrical system. In most gasoline-powered models, the battery group size is typically 65 or 65R with a cold-cranking amps (CCA) rating around 650–750 A. If you drive a Fusion Hybrid, there is also a high-voltage propulsion battery, but the 12V battery remains part of the auxiliary system.
Gasoline-powered Fusion: battery type and replacement specs
The following details cover the gasoline versions commonly found in 2010 Fusions and what to look for when replacing the battery.
- Battery type: 12-volt automotive lead-acid battery, typically maintenance-free (sealed).
- Group size: commonly 65 or 65R for many 2010 Fusion models.
- Cold-cranking amps (CCA): typically around 650–750 CCA for reliable cold-weather starting.
- Other specs to match: reserve capacity around 100–110 minutes; verify exact dimensions and terminal orientation to ensure proper fit and cable routing.
In short, the gasoline-powered 2010 Fusion most often uses a 12V lead-acid battery in group size 65 or 65R with roughly 650–750 CCA; confirm the exact spec from your current battery label or an official parts lookup.
Fusion Hybrid and other variants
For the Fusion Hybrid, the drivetrain includes a high-voltage propulsion battery in addition to the standard 12V auxiliary battery. The 12V battery remains a conventional 12V lead-acid unit, while the high-voltage pack (NiMH) powers the hybrid system. Replacement of the high-voltage pack is not a routine DIY task and should be handled by trained technicians.
- 12V auxiliary battery: generally a standard 12V lead-acid battery used for electronics and normal vehicle functions; group size is typically similar to the gas model, but verify with the label or VIN.
- High-voltage battery: nickel-metal hydride (NiMH) pack used for propulsion; not a typical replacement battery for everyday service.
- Maintenance considerations: hybrids rely on a DC-DC converter to keep the 12V battery charged from the high-voltage system; service should follow official guidance to ensure safety and compatibility.
Note: Do not attempt to service or replace the high-voltage battery yourself; seek assistance from an authorized Ford service center or a qualified technician.
Summary
The 2010 Ford Fusion primarily uses a 12-volt lead-acid battery for the gasoline models, typically in group size 65 or 65R with about 650–750 CCA. The Fusion Hybrid adds a high-voltage NiMH propulsion pack, while the 12V battery remains the conventional auxiliary unit. Always verify the exact group size and CCA on the current battery or via a VIN-based parts lookup to ensure a correct replacement.
