BATTERY CHARGING
• 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 (–20˚C to +60˚C; –4˚F
to +140˚F) and the battery itself (–20˚C to +60˚C; –4˚F to
+140˚F). 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 bat-
tery may exceed that of the transceiver. In such cases, the
transceiver 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 exces-
sive temperature environment (above +45˚C; +113˚F) for an
extended period of time. If the battery must be left unused
for a long time, it must be detached from the radio after dis-
charging. You may use the battery until the remaining ca-
pacity 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) (within a month)
–20˚C to +35˚C (–4˚F to +95˚F)
–20˚C to +20˚C (–4˚F to +68˚F)
24
(within three months)
(within a year)
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.
• WARNING! DO NOT charge or leave the battery in the bat-
tery 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 rup-
ture.
• WARNING! NEVER insert the battery and transceiver (bat-
tery 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 outside of the speci-
fied temperature range: ±0˚C to +45˚C (+32˚F to +113˚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.
