What is the battery under the seat in a 2005 chevy trailblazer for?

I'm trying to hook up the sound ststem in my truck and wanted to see if i could hook it up to the battery that's under the seat.

it is for your power seats

is it for electronic controls for moving the seat? I have bum warmers in the seats and the motor for that is underneath
