Battery pack life
When the operating period becomes extremely short even after
charging the battery pack fully, a new battery pack is needed.
NOTE: The charger rapidly charges a battery pack to a speci-
ed level, not a completed level, to prevent overcharging. Leave
the battery pack in the charger for a few more hours (up to
15 hours; depending on battery condition) after the LED indica-
tor turns green, to charge the battery completely.
