BATTERY CHARGING
3
BE SURE To NOT
use the battery pack out of the specified
temperature range for the transceiver –25°C ~ +55°C and
the battery itself –20°C ~ +60°C. Using the battery out of its
specified temperature range will reduce its performance and
battery cell’s life. Please note that the specified temperature
range of the battery may exceed that of the transceiver. In
such cases, the transceiver may not work properly because
it is out of its operating temperature range.
BE SURE To NOT
leave the pack fully charged, completely
discharged, or in an excessive temperature environment
(above 50°C) for an extended period of time. If the battery
pack must be left unused for a long time, it must be
detached from the transceiver after discharging. You may
use the battery pack until the remaining capacity is about
half, then keep it safely in a cool and dry place at the
following temperature range:
–20°C ~ +50°C (within a month)
–20°C ~ +40°C (within three months)
–20°C ~ +20°C (within a year)
BE SURE
to replace the battery pack with a new one
approximately five years after manufacturing, even if it still
holds a charge. The material inside the battery cells will
become weak after a period of time, even with little use. The
estimated number of times you can charge the pack is between
300 and 500. Even when the pack appears to be fully charged,
the operating time of the transceiver may become short when:
• Approximately 5 years have passed since the pack was
manufactured.
•The pack has been repeatedly charged.

Charging caution
R
WARNING! NEVER
charge the transceiver during a
lightning storm. It may result in an electric shock, cause a
fire or damage the transceiver. Always disconnect the power
adapter before a storm.
R
WARNING! NEVER
charge or leave the battery 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 may rupture.
BE SURE
to occasionally observe the battery pack
condition while charging. If any abnormal condition occurs,
discontinue using battery pack.
CAUTION: DO NOT
insert the transceiver (battery attached
to the transceiver) 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: DO NOT
charge the battery pack outside of the
specified temperature range: 10˚C to 40˚C. Icom recommends
charging the pack at 25˚C. The pack may heat up or rupture if
charged out of the specified temperature range. Additionally,
pack’s performance or battery cell life may be reduced.
BE SURE to NOT
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
environments, the safety/protection circuit in the battery will
activate, causing the battery to stop charging.
