Seneca I Electrical System

[pilot_nate]

I was reviewing the Seneca I Electrical Sysytem/Diagram today (for an interview), and I can't figure out where the Battery fits into the equation. I know How the electrical system works, but the diagram does not show the battery, and I could see the interviewer ask, "Where is the battery?" Any help would be great, thanks!!

It doesn't look like much, but if it's anything like the Seneca II it's sort of in the "lower middle" of the diagram
