CAUTION:
DO NOT
use the battery pack out of the specified
temperature range, –20˚C to +55˚C. Using the battery pack
out of its specified temperature range will reduce its perfor-
mance and battery cell's life.
CAUTION:
Shorter battery life could occur if the battery pack
is left fully charged, completely discharged, or in an excessive
temperature environment (above +50˚C) for an extended pe-
riod of time. If the battery must be left unused for a long time,
it must be detached from the transceiver after discharging.
You may use the battery until the remaining capacity is about
half, then keep it safely in a cool dry place with the following
temperature range:
–20˚C to +50˚C (within a month)
–20˚C to +35˚C (within three months)
–20˚C to +20˚C (within a year)
BE SURE
to replace the battery pack with a new one approxi-
mately five years after manufacturing, even if it still holds a
charge. The inside battery material will become weak after a
period of time, even with little use. The estimated number of
times you can charge the battery is between 300 and 500.
Even when the battery appears to be fully charged, the oper-
ating time of the transceiver may become short when:
• Approximately five years have passed since the battery was
manufactured.
• The battery has been repeatedly charged.

Charging caution
R
DANGER! NEVER
charge the battery pack in areas with
extremely high temperatures, such as near fires or stoves,
inside a sun-heated vehicle, or in direct sunlight. In such en-
vironments, the safety/protection circuit in the battery will ac-
tivate, and stop charging.
R
WARNING! NEVER
charge the transceiver during a light-
ning storm. It may result in an electric shock, cause a fire or
damage the transceiver. Always disconnect the power adapt-
er before a storm.
R
WARNING! NEVER
charge or leave the battery pack in
the battery charger beyond the specified time for charging. If
the battery is not completely charged by the specified time,
stop charging and remove the battery from the battery charger.
Continuing to charge the battery beyond the specified time limit
may cause a fire, overheating, or the battery cells may rupture.
R
WARNING! NEVER
insert the transceiver (with the battery
pack attached) into the charger if it is wet or soiled. This could
corrode the battery charger terminals or damage the charger.
The charger is not waterproof.
CAUTION: NEVER
charge the battery outside of the speci-
fied temperature range: BC-160 and BC-171 (0˚C to +45˚C).
BC-119N and BC121N (+10˚C to +40˚C). Icom recommends
charging the battery at +20˚C. The battery may heat up or rup-
ture if charged out of the specified temperature range. Addi-
tionally, battery performance or battery life may be reduced.
