Get a Voltmeter or use the Hidden OBC Menu to verify the running Voltage.
Also keep in mind the E70 and probably other similar platforms have a VERY POOR method to notify the driver there is a charging problem. I really do not think the E70 can notify the driver!!

I run a wire UltraGauge on my X5 with threshold alarms for Temperature and Voltage.

Low Voltage an any modern vehicle will cause ALL sorts of crazy problems. |
The hidden OBC menu looks complex so I would prefer to stick with the voltmeter for now.
I just dropped the battery off at batteries plus for a recharge. I charged it on 2amp for 1 hour before taking it over. Their readings were 12.03V w/ 756 CCA of a 850 CCA rating.
