In this article, we will explore the topic in a simple and clear way. If you are considering making the switch to electric or if you already own an electric car, you will have all the information you need to make your choice to also better evaluate the warranty aspect and manage your car without surprises.
The electric car battery: how long it lasts and when to replace it
The battery life of an electric car is a hotly debated topic and a frequent cause of concern for those considering a switch to electric. The reality is that there is no battery “expiration date” beyond which replacement will be necessary. Lithium-ion batteries over the years can lose some of their initial capacity, thus necessitating multiple charging stops to make the same journey, but their life within a vehicle can safely be as long as 15 to 20 years. Manufacturers generally guarantee batteries for between 6 and 8 years or 100,000 to 200,000 kilometers depending on the vehicle model and battery size. But how to assess the health of the battery? The easiest sign to observe is the decrease, in percentage, of the range: if you notice that your car travels significantly fewer kilometers on a full charge, it may be time to consult an expert.
How does the battery warranty work?
What happens if the battery has problems during the warranty period? The warranty for electric car batteries generally covers manufacturing defects and significant capacity loss, which is defined as a reduction in battery capacity below a certain level, usually between 70% and 80%. In such cases throughout the warranty period, the vehicle battery is replaced free of charge. As with all warranties on goods, it is advisable to read the terms and conditions carefully to understand what is covered and what is not. Finally, it is important to note that the end of the warranty does not automatically mean the “end of life” of the battery: if there are problems, you will no longer be entitled to a free replacement, but the life of the battery could safely extend as we have seen for as many years of use.
Criteria to consider on electric car battery warranty
When it comes to warranty, there are some parameters to consider:
- Durability: As we mentioned, many warranties cover batteries for a period of 6-8 years or a certain mileage. Make sure you know the features of the warranty for the battery in your car or the one you are considering buying.
- Type of failures: Some contracts may exclude specific types of damage, such as those sustained in an accident.
- Included services: Check what ancillary services are included in the warranty contract, such as roadside assistance or the right to a replacement car.
- Documentation: It is essential to keep all documents related to the purchase and maintenance of your electric car, as they may be required in case of service.
Car battery maintenance tips
To extend the life of the battery and keep it in excellent condition, there are some simple maintenance tips to follow:
- Regular recharging: Do not leave your car battery over-charged or over-discharged for prolonged periods. It is advisable to keep the state of charge between 20% and 80%.
- Avoid extreme temperatures: Like all technologies, the battery has an optimal temperature range. Avoid exposing your car to very high or very low temperatures for extended periods.
- Use slow charging when possible: When you have time, prefer slow charging rather than high-power charging, which is less aggressive on materials.
- Monitor range: Keep an eye on your car’s range and if you notice a significant drop, contact a trained technician.
Knowing how long your battery will last, when the warranty comes into play, and what parameters to watch for will help you make more informed and confident decisions. In addition, following simple maintenance tips can extend the life of your battery, allowing you to enjoy your electric driving experience to the fullest. With an electric car, you not only contribute to a more sustainable future, but you can do so with the peace of mind of having a warranty that protects you.
