Because of the chemical reactions inside the battery. I can only assume that the battery is the discharge state, or has a "LOAD" on it. (Even though batteries get hot while being charged). The battery uses a process of electrochemical reaction to produce electrons. This process is what is causeing the heat.
Depends on which year it is. Some will use C cell batteries (particularly those from the 1980s and earlier), while others will use AA batteries.

When Batteries Get HOTAll batteries when drawing power out [or charging], at a very high rate are working hard, and when work is done, everything get warmer!!!!!
the 2003 version weighed in at 2630 lbs shipping weight. This is before water batteries, belongings or awning are added to the trailer.
you go blind
The cable in the electrotransmitter shorts, causeing slight radiation to release and thats why its hot
no that's stupid

I would opt for the two twelve volt batteries in parallel. This configuration will give you the voltage that you need for the system to properly operate plus the endurance time that you can draw from the batteries will be doubled. The amp/hours capacity of batteries when in parallel are additive.
You have to take special care when handling cell phone batteries as they can gt hot and explode open sometimes.
Telephone batteries commonly get hot because they are a form of lithium batteries. All batteries contain chemical reactions within them that produce some amount of heat, it is just that lithium batteries produce great amounts of it.
I think that the best temperature for storing batteries is probably in a dry not-cold or not-hot room
