      Draining Lithium Ion battteries is a bad idea. Lithium Ion does not
      suffer from the memory loss associated with Nickle Cadmimum batteries,
      where discharging them would "reset" the molecules because they forgot
      how to take a charge after a while. When you drain a li-ion battery,
      all you are doing is shortening its life.

      You need a new battery. DON'T periodically discharge it, in fact, it
      should be kept well charged whenever possible. I leave the units I have
      for sale plugged in all the time. The batteries have internal circuitry
      to regulate the charge current, and when they are full, they simply stop
      taking any more current.
