BATTERY CHARGING
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 extended period of time.
If the battery must be left unused for a long time, it must be de-
tached from the radio after discharging.
You may use the battery until the remaining capacity is about half,
then keep it safely in a cool dry place within the temperature range
as shown 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 ex-
tremely high temperatures, such as near fires or stoves, inside
a sun heated car, or in direct sunlight. In such environments, the
safety/protection circuit in the battery will activate, causing the bat-
tery 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 re-
move the battery from the battery charger. Continuing to charge the
battery beyond the specified time limit may cause a fire, overheat-
ing, or the battery may rupture.
R WARNING! NEVER insert the transceiver (battery 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 specified
temperature range: BC-193 (+10˚C to +40˚C; +50˚F to +104˚F).
Icom recommends charging the battery at +20˚C (+68˚F). The bat-
tery may heat up or rupture if charged out of the specified tempera-
ture range. Additionally, battery performance or battery life may be
reduced.
