There's no way to know whether or not it has a battery. Maybe it's on a UPS, for example.

All I know is that my desktop runs at about 70W idle vs. 450W fully-loaded. Unnecessary use of the CPU wastes money regardless of whether or not you're using that money to charge a battery.

Sites can get your battery level from the browser.

IIRC, most of the browsers are going to do away with this functionality soon, however.
