From the kludger:
While half way trimming my hair the built-in battery got drained. I had a meeting in 1 hour and charging would had taken 3 - 4 hours. I decided to open it up only to find a NiMH AAA battery soldered on. I ripped it out, pulled the wires to the exterior. Wired up a standard AAA battery while keeping it in good contact with two of my fingers, while finishing up the job. Worked like a charm. Not a pretty sight through.
