Hybrid vehicles contain two distinct batteries: a standard 12-volt auxiliary battery and a larger traction battery. A failure in the 12-volt battery typically prevents the car from starting or operating accessories, but can often be resolved with a jump-start. Issues with the traction battery are more complex, potentially leading to reduced power, increased fuel consumption, or the vehicle refusing to restart, and require professional diagnosis and repair.
