How often should I change the battery in my BMW i3?

I'm considering purchasing a used BMW i3 and I'm wondering how often I should expect to change the battery. Is it a costly and frequent maintenance issue?

The battery in the BMW i3 is expected to last around 8-10 years or 100,000 miles, whichever comes first. So unless you plan on driving extremely long distances every day, you should not have to worry about replacing the battery too frequently.

It's always a good idea to have the battery checked by a trained technician at least once a year. They can perform a battery capacity test and let you know if there are any issues that need to be addressed.

If you want to ensure your battery lasts as long as possible, try to keep the battery level between 20-80%. Avoid charging it to 100% or letting it completely drain often. This can help prolong the battery's lifespan.
