How long do electric car batteries last?

The battery is generally the first source of questions when considering an electric car. But, as we will see, overall you will never have to worry about it.

There are more and more electric cars, charging stations are multiplying, and purchase aids are still relevant in France to encourage motorists to change their thermal car for a model advertised as “cleaner”.

Even if the electric tends to become more democratic, this energy, which remains, whatever may be said, relatively recent in the automotive world, raises some questions. Among the most frequent, there are obviously those related to the battery. Indeed, you have surely noticed that your smartphone or laptop no longer has the same autonomy after several years of use.

Unlikely to have a problem

On a car, it’s the same principle, batteries have a lifespan. But rest assured, unless you buy a vehicle over ten years old, that is to say one of the first Zoe or one of the first second-hand Nissan Leaf, you will probably never have battery problems. Indeed, most, if not almost all electric cars, use the same type of technology.

Regardless of brand or model, the battery of an electric car lasts between 10 and 20 years, which is far more than the overall retention time of a car. Thereby, you’ll never have to worry about iteven less if you opt for a new model.

Let’s say that car batteries are also a little more “advanced” than those of smartphones and other tablets. The degradation in case of maximum load exists, of course, but it is slower. In addition, the battery packs are guaranteed for several years, albeit with a minimum retention for the most part (generally 70%), but the warranty still runs for eight years in the vast majority of cases.

What are the dangers for the battery?

The danger is therefore when you buy a used electric car. For the moment it is not yet real, because the second-hand electric vehicle market is still very recent. But it will probably be necessary to think about it in the future, especially since replacing a battery pack is expensive, on average 10,000 euros.

To extend the life of the battery, it’s more or less the same as on an electronic device: prefer small regular recharges rather than full of electricity which tend to tire the battery. At the same time, it is advisable to avoid too regular fast charges, or to leave the car constantly plugged in, especially when it is at 100%.
