Most common cause for finding a dead NHW20 Prius 12v accessory battery
is from the dome light in the cargo area being left on, usually from
the rear hatch not being closed properly.
Always lock your Prius either by the Smart system or the remote - the
Prius will not lock the car if a door is left open, and the open door
(usually the rear hatch) will cause the 12v battery to deplete faster
than just the Smart system or the alarm system's parasitic drain...

Another comment for the OP... If this ever happens again, you don't
need to "find and uncover" the battery. Toyota provides a jump start
terminal near the fuse enclosure. ...Pat

Thanks. I remembered the front terminal after I did the jumper on the
battery thing. It's worth a dry run though as I found that removing the
cover on the front terminal took some fiddling.
