D Charging Caution - Icom IC-M35 Instruction Manual

BATTERY CHARGING
CAUTION: Always use the battery within the specific 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
specific temperature range will reduce the battery's perfor-
mance and battery life. Please note that the specified temper-
ature range of the battery may exceed that of the transceiver.
In such cases, the transceiver may not work properly be-
cause 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) 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 tempera-
ture range as below;
–20˚C to +50˚C (within a month)
–20˚C to +35˚C (within three months)
–20˚C to +20˚C (within a year)
BE SURE to replace the battery pack with a new one approx-
imately 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.

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 environ-
ments, the safety/protection circuit in the battery will activate,
causing the battery to stop charging.
R WARNING! NEVER charge the transceiver during a light-
ning 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! DO NOT charge or leave the battery in the
battery charger beyond the specific time for charging. If the
battery is not completely charged by the specific time, stop
charging and remove the battery from the battery charger.
Continuing to charge the battery beyond the specific 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: DO NOT charge the battery outside of the specific
temperature range: ±0˚C to +40˚C. Icom recommends charg-
ing the battery at +20˚C. The battery may heat up or rupture
if charged out of the specific temperature range. Additionally,
battery performance or battery life may be reduced.
