How do I maintain the battery in my BMW i8?

I have recently purchased a BMW i8 and I'm concerned about how to properly maintain the battery. What steps should I take to ensure the longevity and performance of the battery?

The best way to maintain your BMW i8's battery is to regularly charge it fully and avoid leaving it at a low charge for extended periods of time. This can cause the battery to degrade and reduce its performance.

You should also avoid exposing the battery to extreme temperatures, as this can also negatively affect its performance and longevity. If possible, park your car in a shaded area or a covered garage.
