What should I do if the battery won't charge?

First, ensure the battery is fully inserted into the charger until the LED illuminates and the charger is plugged into a working outlet. If the ambient temperature is too hot or too cold, move the charger and battery to a location between 40°F (4.5°C) and 105°F (40.5°C). If problems persist, contact your local service center. (Page 12)
