When the rechargeable battery is charging, the corresponding LED will be red. When
the rechargeable battery is fully charged, the corresponding LED will be green. The
rechargeable battery can remain inserted in the charger until the battery is needed. The

In a fully discharged condition, it may take up to six hours to fully charge a

Charging times will vary for rechargeable batteries in partially charged
states. If the charging LED turns off while the rechargeable battery is
installed, remove the rechargeable battery from the charger, and then
insert the rechargeable battery back into the charger. If charging does not
