In brief: traditional gasoline Mustangs rely on a 12-volt lead-acid battery to start the engine and power accessories, while the Ford Mustang Mach-E, the electric variant, uses a high‑voltage lithium‑ion battery pack around 400 volts to drive the vehicle.
The traditional Mustang: a 12-volt system
Overview of the ICE battery setup
Most gasoline-powered Mustangs use a standard 12-volt battery to crank the starter and supply the electrical system when the engine is off. In recent years, Ford has tended to equip these cars with AGM (absorbed glass mat) batteries to improve cold-weather performance and reliability for the car’s electronics.
Before the list below, a quick look at the key points about the traditional Mustang’s 12-volt battery:
- Purpose: starts the engine and powers the 12-volt electrical system when the engine isn’t running.
- Technology: newer Mustangs commonly use AGM batteries for better durability and performance in cold weather.
- Replacement considerations: battery size and specifications vary by model year and trim; check the owner’s manual or a parts retailer to confirm the correct fit.
Maintaining the 12-volt battery typically involves monitoring charge, ensuring clean and tight terminals, and replacing it according to Ford’s maintenance schedule or when performance declines.
Mustang Mach-E: high-voltage pack powering an EV
What powers the electric drive
The Mustang Mach-E relies on a large high‑voltage lithium‑ion battery pack (about 400 volts) to propel the vehicle and supply most of the electrical systems. Depending on the model year and trim, usable capacity generally sits around 68 kWh for the standard-range version and about 88 kWh for the extended-range version.
Before the list below, a quick look at the essential features of the Mach-E’s battery system:
- Type: high‑voltage lithium‑ion battery pack for propulsion, not a conventional 12‑volt battery for driving.
- Voltage: approximately 400 volts to support performance and charging capabilities.
- Variations: pack capacity differs by trim; the 68 kWh net is typical for base configurations, while the 88 kWh net is offered on higher trim levels.
In an EV like the Mach-E, the vehicle’s high‑voltage pack is supplemented by a separate 12‑volt system that powers standard electronics, typically via a DC‑DC converter from the main pack.
Summary
In short, the Ford Mustang lineup comprises two distinct battery technologies depending on the model: traditional gasoline Mustangs use a standard 12‑volt lead‑acid (often AGM) battery, while the Mustang Mach-E uses a 400‑volt high‑voltage lithium‑ion battery pack with 68–88 kWh of usable capacity depending on configuration. Always verify the exact specifications for your specific model year and trim with Ford’s official documentation or a dealership.
Additional context
Battery technology and capacities can change with new model years and regional variants. If you’re shopping or maintaining a Mustang, consult the owner’s manual or a Ford service center for precise current specifications.
