(1)
Three dot between battery and transistor indicate the relation between them. Here transister work as temprature sensor and it will work according to temprature of battery. It is one kind of feedback. transister is placed near to battery and due to battery temprature operating point of the transiste is changed and provide the result according to temprature.
