The Honda Clarity lineup uses different battery configurations depending on the variant: the Plug-In Hybrid has about 17 kWh of usable capacity, the Electric version uses about 25.5 kWh, and the Fuel Cell variant relies on hydrogen fuel cells with no large conventional battery.
Battery capacities by Honda Clarity variant
Below are the commonly cited battery sizes for the main Clarity models marketed in the United States. Exact figures can vary slightly by year and region.
- Clarity Plug-In Hybrid (PHEV): approximately 17 kWh of usable battery capacity.
- Clarity Electric (BEV): approximately 25.5 kWh battery capacity.
- Clarity Fuel Cell (FCEV): does not use a large conventional battery; energy is generated by the hydrogen fuel cell stack, with only a small auxiliary buffer battery whose kWh rating is not typically published.
These figures reflect the standard configurations widely documented for North American-market Clarity models. Real-world figures can differ based on year, trim, and regional packaging.
What these numbers mean for range and charging
The 17 kWh pack in the Clarity PHEV historically supported an EPA-estimated electric range in the 40s miles per full charge, depending on driving conditions. The 25.5 kWh pack in the Clarity Electric enabled a higher electric range, typically in the 80–90 mile band in early configurations, though real-world results vary with climate, speed, and use of climate control. The Fuel Cell variant does not provide a traditional miles-per-charge figure; its range depends on hydrogen fuel availability and tank capacity, with the battery primarily serving system buffering rather than propulsion.
Notes for buyers and owners
When evaluating a Clarity, verify the exact battery specification for the specific model year and region, since Honda offered multiple configurations over its run and production phased out in some markets. Battery health and charging habits can also influence real-world performance.
Summary
The Honda Clarity lineup comprises three variants with distinct powertrain architectures. The Plug-In Hybrid uses about 17 kWh of usable battery capacity, the Electric version uses about 25.5 kWh, and the Fuel Cell variant relies on hydrogen fuel cells with no large conventional battery. For precise figures, consult the exact model-year documentation from Honda or a dealer.
