BATTERY CHARGING
D
Battery caution (Continued)
CAUTION:
Shorter battery life could occur if the battery 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
temperature range as below:
–20˚C to +50˚C (within a month)
–20˚C to +40˚C (within three months)
BE SURE
to replace the battery pack with a new one ap-
proximately 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
environments, the safety/protection circuit in the battery will
activate, causing the battery to stop charging.
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.
R
WARNING! NEVER
insert the transceiver (battery at-
tached 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: NEVER
charge the battery outside of the speci-
fied temperature range: +10˚C to +40˚C. Icom recommends
charging the battery at +20˚C. The battery may heat up or
rupture if charged out of the specified temperature range. Ad-
ditionally, battery performance or battery life may be reduced.
