How long is the battery life on the Ford Cmax Energi?
The Ford C-Max Energi offers about 20 miles of electric range on a full charge, powered by a 7.6 kWh lithium‑ion battery; in the U.S., Ford backs this with an 8-year/100,000-mile hybrid-battery warranty, though real-world life varies with climate and usage.
Battery size and electric range
Key numbers you should know about the Energi’s battery and its electric driving capability are listed below.
- Battery capacity: 7.6 kWh lithium‑ion pack
- All-electric range: EPA-estimated about 20 miles on a full charge (varies with conditions)
- On-board charger: 6.6 kW, enabling relatively quick Level 2 charging
These figures determine how often you’ll rely on electric power for daily trips and how you plan charging sessions.
Charging options and times
Charging times vary by outlet and circuit, with the Energi designed for flexible home charging and occasional public charging.
- Level 1 charging (120V): typically completes a full charge overnight, depending on circuit and starting state of charge
- Level 2 charging (240V): generally about 2–3 hours to full recharge from empty, thanks to the 6.6 kW onboard charger
- DC fast charging: not available on the C-Max Energi
In practice, most owners top up during the day at home or work to maximize electric driving.
How long will the battery last: lifespan and warranty
Battery life depends on usage, climate, and charging habits. The following points summarize typical protections and expectations.
- Warranty: In the United States, Ford typically offered an 8-year/100,000-mile warranty for the hybrid battery and related components
- Expected lifespan: Lithium‑ion packs in plug‑in hybrids generally provide many years of service; capacity tends to degrade gradually, with more noticeable drops over many years in extreme heat or cold
Proper care—such as moderate exposure to extreme temperatures and using Level 2 charging when available—can help maximize longevity.
Summary
The C-Max Energi delivers around 20 miles of electric range per charge from a 7.6 kWh battery, with Level 2 charging offering a practical refill time of a few hours. It does not support DC fast charging. The hybrid battery is covered by an 8-year/100,000-mile warranty in the U.S., and real-world life depends on climate and driving patterns, typically offering many years of service with proper care.
