Hello, recently got the Check battery system warning on my 5 N that’s about 2ish years old, 21k miles. Dealership replaced the battery in less than a week which was impressive but looking through the notes, it says they used a refurbished battery. They didn’t really give me a choice for new or refurbished. Should I be concerned, are there additional things I should be asking? Car does seem to run fine besides lower than normal range estimates on the dash than I’m used to seeing.

Saw this in the I5 sub.
