CHARGING THE BATTERY PACK WITH
BATTERY CHARGER
•Remove the battery pack from the tool for charging at a
convenient time. The R2 Rechargeable Speed Ratchet
batteries do not develop a “memory” when charged
afteronly a partial discharge. It is not necessary to run
down the battery pack before placing it on the charger.
•You can “Top-Off” your battery pack’s charge before
starting a big job or an expected long period of use.
•The only time it is necessary to charge the R2
Rechargeable Speed Ratchet lithium-ion battery pack
is when the battery pack has reached the end of its
charge. To signal the end of charge (indicatorlight is
continuous red),power to the tool will drop quickly. The
battery pack will need to be charged.
•When using the R2 Rechargeable Speed Ratchet with
lithium-ion batteries, usage musthalt and the batteries
charged immediately when LED indicator light shows
continuous red (low voltage protection). This is in order
to prevent damage and ensure product lifespan.
•When lithium-ion batteries are left unused for over 3
months, they must be charged before use in order to
maintain their lifespan.
•Lithium-ionbatteries must be charged periodically in
order to maintain theirlifespan.
HOW TO CHARGE THE BATTERY PACK
•Align the battery pack with the bay and slide/insert
the battery pack into the battery charger as faras
possible. The LED light will come on, either flashing or
continuous.
•Afully discharged battery pack with an internal
temperature in the normal range will charge in
approximately 45minutes.
•After charging is complete, the greenindicator light will
stay lit.
•The battery charger will keep the battery pack fully
charged as long as it is left on the charger.
•If the indicatorlight does not come on, check that the
battery pack is fully seated into the bay. Remove the
battery pack and reinsert. If the indicatorlight still does
not come on, contact a service agent.
•If the light continues to flash red and green at the
same time on the charger, the battery pack may be
excessively hot (104°F/40°C or more) or cold (32°F/0°C
or less). Allow the batterypackto cool down, warm up,
and then reinsert.
*If the problem persists, contact a service agent. Once
the battery pack is within the acceptable range, normal
charging will take place.
