Follow these steps to charge your batteries for the first time:
1
Lift up the cover of the charger and insert all four
batteries, positioning the + and – ends as shown. Then
close the cover firmly.
2
Turn the charger over and flip the two prongs out of
their compartment.
3
Plug the charger into an electrical outlet. Both lights
turn red, indicating that the charger is working. When
the batteries are charged, after about two and a half
hours, the lights go off.
NOTE
The charger lights flash to indicate changes in battery
temperature and voltage. If the lights continue to flash for
more than half an hour, the batteries may be damaged or
worn out, and should be replaced. Unplug the charger if the
batteries are not fully charged after four hours.
