Looks like its time to get a new battery after 6 years :/ (Discharge Warning) The dealer quoted over 500$ total and I've been searching the forums for some form of DIY for this and have mixed info. So I've been searching for a battery and found a Duracell

I guess my question is does this battery meet the OEM specs. And also I heard that the bmwlogger tool is good for battery registration but a good OBD 2 cable is needed to work. Anyone have any ideas? Much thanks for any input.
