End Of Life

Even the longest lasting battery will eventually reach its end-of-life. We do not expect any BYD batteries returning anytime soon, and we believe you still have many many years to enjoy your battery; but we would already like to inform you about what will happen, once the battery reaches its end of life.

The end of life is a new start!

With its highest goal – the „Zero-Emission-Eco-System“ – BYD always looks at the complete journey of the Battery. From cradle to grave. Therefore BYD already has the end-of-life in mind upon developing a new battery. This is why the end of life is actually a new start. With a second life or by an effective recycling, the batteries can be fed into a circular economy.

Once your battery reaches its end-of-life, you can contact us at:

Please include:

- All Serialnumbers of your batteries
- Tell us if you need packaging
- The complete pickup address (Name, Street, ZIP, City, Country, Phone, Email)
