Charging Cautions - Icom IC-R15 Basic Manual

BE SURE to replace the battery pack
with a new one approximately five years
after manufacturing, even if it still holds
a charge. The material inside the battery
cells will become weak after a period of
time, even with little use. The estimated
number of times you can charge the pack is
between 300 and 500. Even when the pack
appears to be fully charged, the operating
time of the receiver may become short
when:
• Approximately 5 years have passed since
the pack was manufactured.
• The pack has been repeatedly charged.
The battery cells may deteriorate and
swell due to their characteristics if used in
an environment and conditions such as:
frequently charged, recharged immediately
after full charge, used or saved in a hot
place, or charged by methods other than
the instructions. If the battery pack swells,
it has reached the end of its life due to
deterioration. Replace it with a brand new
one.

■ Charging cautions

R DANGER! NEVER charge the battery
pack in areas with extremely high
temperatures, such as near fires or stoves,
inside a sun-heated vehicle, or in direct
sunlight. In such environments, the safety/
protection circuit in the pack will activate
and stop the charging.
R WARNING! NEVER charge the receiver
during a lightning storm. It may result in
an electric shock, cause a fire, or damage
the receiver. Always disconnect the power
adapter before a storm.
R WARNING! NEVER charge or leave
the battery in the battery charger beyond
the specified time for charging. If the pack
is not completely charged by the specified
time, stop charging and remove it from the
battery charger. Continuing to charge the
pack beyond the specified time limit may
cause a fire, overheating, or the battery
may rupture.
R WARNING! Occasionally observe the
battery pack condition while charging. If
any abnormal condition occurs, discontinue
using the battery pack.
CAUTION: DO NOT insert the receiver
(battery attached to the receiver) 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
pack outside of the specified temperature
range: 15˚C ~ 40˚C (59˚F ~ 104˚F). Icom
recommends charging the pack at 25˚C
(77˚F). The pack may heat up or rupture if
charged out of the specified temperature
range. Additionally, battery performance or
battery life may be reduced.
