A drop from 13 to 12.6 is normal on most vehicles.  What would not be normal
is for it to drop much more. (age of battery is also a variable in that).
My van parked for a couple days will drop to 12.6 overnight and then down to
about 12.3 after 3 days and 12.1 after 5 days. My aux1 battery (a group 27
deep cycle) drops at a slower rate and has a similar load on it.
