BATTERY CHARGING
R WARNING! NEVER put the battery in a microwave oven,
high-pressure container, or in an induction heating cooker.
This could cause overheating, a fire, or cause the battery
to rupture.
CAUTION: Always use the battery within the specified tem-
perature range for the transceiver* and the battery itself
(–20˚C to +60˚C; –4˚F to +140˚F).
* EXP/USA
CHN/EUR/FRG/HOL/UK : –15˚C to +55˚C; +5˚F to +131˚F
AUS
Using the battery out of its specified temperature range will
reduce the battery's performance and battery life. Please
note that the specified temperature range of the battery may
exceed that of the transceiver. In such cases, the transceiv-
er may not work properly because it is out of its operating
temperature range.
CAUTION: Shorter battery life could occur if the battery is
left fully charged, completely discharged, or in an excessive
temperature environment (above +50˚C; +122˚F) for an ex-
tended period of time. If the battery must be left unused for a
long time, it must be detached from the radio after discharg-
ing. 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 (–4˚F to +122˚F)
–20˚C to +35˚C (–4˚F to +95˚F)
–20˚C to +20˚C (–4˚F to +68˚F)

D 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 car, or in direct sunlight. In such en-
vironments, the safety/protection circuit in the battery will
activate, causing the battery to stop charging.
R WARNING! DO NOT 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 char-
ger. 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 battery and transceiver
(battery attached to the transceiver) into the charger if it is
wet or soiled. This could corrode the battery charger termi-
nals or damage the charger. The charger is not waterproof.
CAUTION: DO NOT charge the battery outside of the speci-
fied temperature range: +10˚C to +40˚C (+50˚F to +104˚F).
Icom recommends charging the battery at +20˚C (+68˚F).
The battery may heat up or rupture if charged out of the
specified temperature range. Additionally, battery perfor-
mance or battery life may be reduced.
