This script is supposed to be run overnight; lock the screen brightness at maximum, and disable screen blanking, then run the script, connect the wallcharger and wait. Discharging with the screen at maximum brightness takes about 5 hours, with the standard BL-5J.

THIS SCRIPT NEEDS THE BME REPLACEMENT!
