Is there a reason for using AWG 12 or even 10 wire and the battery?

And for the battery, to save space, maybe a 12V SLA, the one they use in UPSes could do?

I mean, a real car bayttery, if something accidentally shorts, will pull an impressive arc, which will make even an experienced person jump. (I have no experience with old tube car radios, so these are the questions from someone who is trying to understand why certain things are done certain way).
