Does a hybrid have two batteries?
As the owner of Kevin's Autos, I often get questions about hybrid vehicles and their unique components. One of the most common inquiries is whether hybrids have two batteries. In this article, we'll explore the battery systems in hybrid cars, their functions, and what makes them different from traditional vehicles.
Understanding Hybrid Vehicles
Hybrid vehicles combine an internal combustion engine with an electric motor, allowing for improved fuel efficiency and reduced emissions. This dual system requires a sophisticated battery setup to manage the energy flow between the engine and the electric motor.
Battery Systems in Hybrids
Yes, hybrid vehicles typically have two types of batteries:
- High-Voltage Battery: This is the primary battery used to power the electric motor. It stores energy generated during regenerative braking and from the engine. This battery is usually a nickel-metal hydride (NiMH) or lithium-ion battery and is designed to provide the necessary power for acceleration and electric-only driving.
- 12-Volt Battery: Similar to conventional vehicles, hybrids also have a standard 12-volt battery. This smaller battery powers the vehicle's electrical systems, such as lights, radio, and other accessories. It is charged by the high-voltage battery when needed.
How the Batteries Work Together
The two batteries in a hybrid vehicle work in tandem to optimize performance and efficiency:
- The high-voltage battery provides power for the electric motor, allowing the vehicle to operate in electric-only mode or assist the gasoline engine during acceleration.
- The 12-volt battery supports the vehicle's electrical systems and is recharged by the high-voltage battery, ensuring that all components function smoothly.
Conclusion
In summary, hybrid vehicles do indeed have two batteries: a high-voltage battery for the electric motor and a 12-volt battery for standard electrical functions. Understanding these components can help you appreciate the technology behind hybrids and their benefits in terms of fuel efficiency and environmental impact.

Frequently Asked Questions
Do all hybrids have two batteries?
Let's start with some basics. First off, a Hybrid Electric Vehicle, including Plug-In Hybrid Electric, actually has two batteries. A Hybrid battery, and a 12-volt battery, just like in a combustion-engine vehicle. Fundamentally, both batteries operate in a similar way.
How much does it cost to replace a hybrid battery?
$2,000 to $8,000
Average Cost: A hybrid battery replacement cost can range from $2,000 to $8,000, depending on the vehicle's make and model. It's important to note that these are approximate costs, and we recommend contacting our service department for an accurate quote based on your specific vehicle.
Which battery starts a hybrid car?
Hybrid vehicles use both a conventional 12-volt battery and a high-voltage battery pack. If the 12-volt battery dies, the car won't start.
What happens when the 12-volt battery dies in a hybrid car?
If the 12-volt battery system fails, the petrol engine will be unable to start and that will also generally put a stop to play even if the high-voltage batteries are fully charged. Some hybrids such as the Toyota Prius give you three attempts to start the petrol engine after which, the car actually needs to be reset.
