CHARGING THE BATTERY
NOTE: The battery is not shipped fully charged.
NOTE: Lithium-ion batteries will not develop a memory and may be
charged at any time.
For maximum run time, fully charge the battery before each use.
1. Plug the battery charger into an appropriate power outlet.
2. Insert the battery into the charging dock (Fig. 2). The LED should

• Make sure the battery is fully inserted into the charging dock.
• Make sure the battery charger is fully plugged into an
appropriate power outlet.
• Make sure the power outlet is functioning by testing it with
another electrical device.
3. Examine the LED. The LED will indicate the battery status:
• Green (blinking): The battery is charging. Charge the battery
until the green light stops blinking.
• Green (constant): The battery is fully charged.
• Red (blinking): The battery and/or charger are too hot or too
cold. Make sure the battery and charger are in an environment
between 32° and 104° F (0° and 40° C). Allow time for the
battery and/or charger to warm up or cool down.
• Red (constant): The battery is no longer functional. Refer to
the Warranty section for replacement information.
4. Once the battery is fully charged, remove it from the battery
charger. Optionally, the battery can be stored in the battery
