I registered the battery but still get the Increased discharge warning. Unplugged the IBS last night after parked, get no warning but car still doesn't want to start without a jump. When I placed the jump pack on it, the voltage was at 9 amps. It's a new battery?!?! What would you guys suggest my next move to be. Plan to take it in to BMW Monday but any info before will help. Thank you in advance.

Even new batteries need to be charged to 100% since most of them tend to be on shelves for a long period of time and tend to lose charge. I'd hook the battery up to a battery maintainer and let it fully charge.
