Charge the battery.

Insert the battery (terminals first), aligning the end of the
battery with the guide and then sliding the battery in the
direction indicated until it clicks into place. The chamber lamp
and charge lamps will flash slowly while the battery charges:

Charging is complete when the chamber lamp stops flashing
and the charge lamps turn off. About two hours and twenty
minutes are required to fully charge an exhausted battery;
note that the battery will not charge if its temperature is
below 0 °C (32 °F) or above 60 °C (140 °F).

Remove the battery when charging is complete.

Remove the battery and unplug the charger.
