Have both batteries tested. Also, any shop equipped with SDS can check the battery control module for fault codes. The charging system is probably OK, since the warning message goes away after a few minutes.

One of your batteries needs to be replaced, as it's losing enough voltage overnight to trip the warning. Usually the small one under the hood goes first.
