What kind of battery does a Toyota Yaris have?
Two different battery systems are used across the Yaris lineup: conventional gasoline models carry a standard 12-volt lead-acid battery, while the Yaris Hybrid relies on a high-voltage battery to power the electric motor. There is no widely available plug-in Yaris variant in the latest models.
Two main configurations of the Yaris line
The Yaris is offered in two primary configurations. One is the standard gasoline-powered model with a conventional 12V battery; the other is the hybrid version that combines a petrol engine with an electric motor and a separate high-voltage battery.
- Non-hybrid Yaris: a standard 12-volt lead-acid battery used to start the engine and power accessories and electronics.
- Yaris Hybrid: a high-voltage battery that powers the electric motor and assists the petrol engine; this pack is typically nickel-metal hydride (NiMH) in most markets.
These configurations reflect the two primary powertrain approaches in the Yaris lineup and determine the type and role of the battery in the car's operation.
Details by drivetrain
Non-hybrid Yaris (gasoline) battery
The traditional Yaris is equipped with a 12-volt lead-acid battery. It provides power for starting the engine, the lighting system, and onboard electronics. It is charged by the alternator while the engine runs and may be replaced as part of routine maintenance.
Yaris Hybrid battery
The Yaris Hybrid uses a high-voltage battery pack to store energy for the electric motor. The battery is typically a nickel-metal hydride (NiMH) pack and is managed by the hybrid system to enable electric propulsion, regenerative braking, and improved fuel economy. The exact capacity and layout can vary by model year and market, but NiMH has been the standard for Yaris Hybrid models across generations.
Additional considerations
Maintenance, replacement intervals, and service requirements differ between the two battery types. The 12V battery is a consumable part with a typical life of several years, while the hybrid battery is designed for long life and is often covered by Toyota warranties for a set period or mileage. If you own a Yaris Hybrid and notice a drop in electric-assisted performance or unusual charging behavior, a diagnostic check at a Toyota service center is recommended.
Summary
Bottom line: If you own a Toyota Yaris, the battery type depends on the model. A non-hybrid Yaris uses a standard 12-volt lead-acid battery; a Yaris Hybrid uses a high-voltage battery, typically nickel-metal hydride (NiMH), to power the electric motor and assist the petrol engine.
