If you have ever wondered what the average lifespan of a hybrid car’s battery is, look no further.
The battery is one of the most expensive components of a hybrid car, so buyers will want to know how much use they can expect to get out of it before it’s time to get a new one.
There are two batteries in each hybrid car – a high voltage battery which powers the motor, usually located under the rear seat, and the 12V battery found in any normal car.
This article will focus on the lifespan of the former.

All the factors that influence the lifespan of a hybrid car’s battery
What exactly does the high-voltage battery do?
It powers the electric motor, stores energy captured from regenerative braking, and assists and sometimes replaces the gasoline engine.

All of that to say, it does a whole lot for the car.
So its lifespan will obviously factor into the decision-making process of anyone looking to invest in a hybrid.
Because who wants to buy a car that’s going to require a costly replacement imminently?
Now, there’s no singular figure that can fit the bill for every hybrid battery.
But here’s what you should know – most batteries are expected to last between 100,000 and 200,000 miles.

That’s no small figure; chances are, that’ll be the lifespan of the vehicle itself.
And what do the warranties say?
The US government requires a minimum warranty coverage of eight years or 80,000 miles on plug-in-hybrid and EV batteries.
For vehicles sold in states that follow California Air Resources Board (CARB) rules, it’s 10 years or 150,000 miles.
In addition to California, those states are Colorado, Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia, Washington, and the District of Columbia.

And then there are the warranties of each company with some slight variations.
Toyota promised a warranty of 10 years and 150,000 miles, while Hyundai offers 10 years and 100,000 miles.

Hybrids seem to be all the rage these days
For a lot of people, hybrid cars are seen as the bridge between gas cars and EVs – hence why they are constantly being compared.
In recent years, more and more information has come out about hybrids, which may make people take a second look.
For example, did you know that EV and hybrid cars need their tires replaced more often?

Then there’s the fact that plug-in hybrids are emitting five times more than what official tests originally claimed.
There’s a whole lot that needs to be weighed up before you can change your car type.
And that includes a hybrid car’s battery.
