Battery charging takes approximately 2 hours
and 20 minutes. When a battery is fully
charged and ready for use, its red light will go
off and the green Ready light next to it will go
on. Refer to Figure 7.
To remove a fully charged battery from the bat-
tery charger, press down on the battery release
tab next to it, and push the battery from the end
near the status lights.
