Selective boot-up batch file

What I could really use is a batch file in my laptop's Startup folder --

Only if I am booting up under battery power, run a specified program;
Only if I am not booting up under battery power, run a different
specified program.

I can program the logic, but how do I get the battery/AC yes/no
information to base the logic on?

Thanks.
