NOTE: Batteries will not reach full charge the first time they
are charged. Allow several cycles (operation followed by
recharging) for them to become fully charged. This is normal
for nickel-cadmium batteries.

LED will begin flashing.
When the battery pack cools down to approximately 104°F
(40°C), the charger will automatically begin fast charge
mode.
If the Red LED continues to flash for more than 90 minutes,
and the green LED remains off, this may indicate a damaged
battery that will not charge.

ING A COOL BATTERY PACK
If the battery pack is below normal temperature range, the
red LED will begin flashing and the green LED will be off.
When the battery warms to a temperature of more than
41°F (5°C), the charger will automatically begin fast charge
mode.

your battery pack under normal circumstances, return both
