How do you repair dead rechargeable Lithium Ion battery?

Answer:
Rechargeable batteries aren't really field-serviceable. If it's for a computer, the computer manufacturer MAY provide a calibration program that discharges and recharges the battery completely which can help, but if the battery is truly dead there's not much you can do other than get a new one and recycle the dead one.
