Selling a genuine BMW OEM AGM car battery, manufactured in 2019 by SEBANG Battery Co., Ltd., Korea (BMW’s official supplier). This was recently removed from my BMW X3 M40i, not due to failure, but simply to get ahead of any potential future battery price increases from tariffs. The battery was/is still working perfectly at the time of removal, with BimmerLink reporting around ~80% battery life remaining. Well kept AGM batteries can last 10+ years, so she should have a couple more years in the tank, at least. New from the dealer is ~$400+ (not including install).
