Battery location

This is a dumb question but. Where is the battery on the 2103sl? I found the jump terminals. No big need just curious.

There is another battery located under the small shelf behind the rear passenger seat.

Thanks
Why two batteries? Are they wired in parallel for higher current or do they have different functions to support?

Small battery for starting the engine. Main battery for all support electronics.
