Battery power source

What is the smallest battery source that i can use to support a device much like an old beeper and a green LED. The beeper only works once or twice per year 4 times at the most, the green LED will be used fulltime. The battery source can not be rechargeable, and cheaper is better.

We had a security audit and one of the requirement was to raise an alarm whenever any user does a data extract.

Is it possible to raise a alert whenever a user does a data extract using ODBC or DTF.Using CL program or any other way.
