Draining NiCds and NiMH batteries to empty is harmful. Don't do it, you're
asking for permanent battery damage. It only works as a stopgap measure if
you don't have a good battery charger that burp-charges instead of
trickle-charges the battery. Most laptop manufacturers get chintzy when it
comes to the recharge circuit, and improperly trickle charge batteries that
work best only when burp-charged.
