Test your 12V Battery by following these instructions.

You want to test 3 things. The voltage in accessory mode, the voltage with a load, and the voltage while charging (engine on).
The Prius 12v is known to die more often than it should. It's wise to replace it with something a little more rugged. http://www.amazon.com/gp/product/B00E16M1S8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
This is NOT the high voltage traction battery that costs thousands. This is the battery that runs the computer, accessories and starts the car.
I can attest to this (GEN II). I just had mine drop on me without any warning. It costs $147 on amazon right now, just ordered mine and I plan to replace it this weekend. Mine has lasted nearly 8 years, so I guess I have that going for me.
Not sure if this is good enough, but I recently put this battery into my prius:

The prius 12v battery is inside the cabin (in the trunk area) so it wasn't a normal lead acid battery.
