8 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 (–15˚C to +55˚C) and the
battery itself (–20˚C to +60˚C). Using the battery out of its
specified temperature range will reduce the battery’s perfor-
mance and battery life. Please note that the specified tem-
perature 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.
• CAUTION! Shorter battery life could occur if the battery is
left fully charged, completely discharged, or in an excessive
temperature environment (above +45˚C) 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 discharging.
You may use the battery until the battery indicator shows
half-capacity, then keep it safely in a cool dry place with the
temperature between –20˚C to +25˚C.

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 envi-
ronments, the safety/protection circuit in the battery will acti-
vate, 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 spec-
ified temperature range: ±0˚C to +45˚C. Icom recommends
charging the battery at +20˚C. The battery may heat up or
rupture if charged out of the specified temperature range.
Additionally, battery performance or battery life may be re-
duced.
