Thank you! Okay so I did the test twice. First time I did it the battery showed 11.2V then when I switched it to accessory it went to 10.9V then starting the car took it down to 10.2V but then quickly shot up to 13.9V after the alternator kicked in. Definitely not good though so I let the car sit for a few minutes and did the test again JUST to be sure ya know? This time the voltage started at 10.4V then in accessory it dropped to 10.2V then when starting it dropped all the way to 9.1V then once again after the alternator kicked on it jumped up to 13.8-13.9V.
So I'm going to make an assumption that the problem is the battery? Thankfully mine has a 4 year warranty on it from Sams Club but here's the other thing my battery is not a AGM battery, does this matter?
This is the exact battery I bought. Should I get a AGM battery instead? Does it make THAT big of a difference? Also if it matters last time I had my X5 into my personal mechanic (which was to replace the alternator and the alternator bracket) he said something about the programming of the car thinking it had a AGM battery in it so he switched it to think it has a normal battery in it.
