Spotlight Cam Battery not charging with solar panel

I just checked all of the cakes with solar panels today and they are still charged. Each camera has anywhere between 10 and 20 events during the day and they are all set up with the snap shot feature. Tomorrow I will pull some used batteries from 4 or 5 stuck up cams and see if the solar panels will truly charge them over the next few days.

The weather here has been cold, only reaching 23 degrees today.
