The 2016 Ford Fusion uses a standard 12-volt lead-acid battery for the starting and electrical system in the gasoline version. Hybrid and plug-in Hybrid variants also carry a high-voltage battery for propulsion in addition to the 12-volt unit. In short: gas and hybrid variants rely on a conventional 12V battery, while the Energi plug-in version adds a larger high-voltage pack for its electric drive.
Gasoline-powered Ford Fusion (non-hybrid)
For the gasoline-only Fusion, the primary battery is a conventional 12-volt lead-acid unit used to start the engine and run accessories. The most common setup is a group size around 94R, with typical cold-cranking amps in the 700–800 A range. Always verify the exact group size by checking the label on your current battery or your owner's manual.
Key specifications you should know if you’re replacing the 12-volt battery in the gas Fusion:
- Battery type: 12-volt lead-acid
- Group size: commonly 94R (verify on your current battery)
- Cold-cranking amps (CCA): roughly 700–800 A
- Replacement tip: use OEM or equivalent high-quality battery (Motorcraft or similar) that fits the vehicle and correct terminal orientation
In most cases, replacement is straightforward: match the group size and CCA rating to the original, and install with the correct polarity. If in doubt, consult a parts professional or your dealership to confirm the exact specs for your trim and climate.
Fusion Hybrid (gas-electric, 2016)
The 2016 Fusion Hybrid uses a standard 12-volt battery for the vehicle’s electrical system, plus a separate high-voltage traction battery that powers the electric drive. The high-voltage battery is a nickel-metal hydride (NiMH) pack, designed to supplement the gasoline engine and improve efficiency. The traction pack is not the same as the 12-volt battery and has different replacement/maintenance considerations.
Key points about the hybrid battery system:
- Traction battery type: Nickel-metal hydride (NiMH)
- Traction battery capacity: approximately 1.4 kWh
- 12V battery: standard lead-acid battery used for accessories and starting the 12V system
- Notes: The high-voltage NiMH pack is managed by the hybrid system and is typically replaced only by trained technicians; the 12V battery is user-serviceable like in the gas model
When replacing or inspecting the 12V battery in a Fusion Hybrid, you’ll follow similar guidelines as the gasoline version, but be mindful of the vehicle’s hybrid system when performing any maintenance that could affect the high-voltage components.
Fusion Energi (plug-in hybrid, 2016)
The 2016 Fusion Energi adds a high-voltage traction battery for plug-in operation, along with the standard 12-volt battery for the conventional electrical system. The high-voltage pack is lithium-ion and is significantly larger than in the regular hybrid, enabling extended electric-only driving.
Key details for the Energi battery setup:
- High-voltage battery type: Lithium-ion (Li-ion)
- High-voltage battery capacity: about 7.6 kWh
- 12V battery: standard lead-acid battery for auxiliary power
- Notes: High-voltage systems require appropriate safety procedures; servicing the HV pack is typically limited to qualified technicians
For Energi ownership, the 12V battery replacement follows the same general guidance as the other variants, while the Li-ion pack maintenance and service are handled by Ford-certified technicians or dealerships.
Summary
In the 2016 Ford Fusion lineup, the standard gasoline model uses a conventional 12-volt lead-acid battery. The Hybrid adds a high-voltage NiMH traction battery for propulsion in addition to the 12V system, while the Energi plug-in Hybrid uses a lithium-ion high-voltage pack (approximately 7.6 kWh) alongside the 12V battery. If you’re replacing a battery, always confirm the correct group size (commonly around 94R for the 12V unit) and CCA rating from your current battery or the owner’s manual, and consider OEM options for compatibility with your trim and climate. A professional service visit is recommended if you’re unsure about the high-voltage components on Hybrid or Energi models.
