DIC--What is the normal charging level

Hello Gang:

Just replaced the battery, what a breast to pull.

In the Driver Information Center, what is the normal charging level.

In the moring I start at 15.0 to 14.9 then start driving around town when the air is on is 14.4, normal driving daylight is 14.7 At night is 14.4 to 14.5

Any feed back would be appreciated.

those numbers sound perfectly fine ..i have noticed that in extream cold they get a bit farther apart like 15.7 to 12.5
