D Charging Caution - Icom ID-31E PLUS Basic Manual

detached from the transceiver after discharging. You may
use the pack until the remaining capacity is about half, then
keep it safely in a cool dry place in the following temperature
range:
–20˚C (–4˚F) ~ +50˚C (+122˚F) (within a month).
–20˚C (–4˚F) ~ +35˚C (+95˚F) (within three months).
–20˚C (–4˚F) ~ +20˚C (+68˚F) (within a year).
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 transceiver may
become short when:
• Approximately five years have passed since the pack was
manufactured.
• The pack 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 vehicle, or in direct sunlight. In such
environments, the safety/protection circuit in the pack will
activate and stop the charging.
R DANGER! NEVER charge the transceiver during a
lightning 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! 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! NEVER insert the transceiver with the battery
pack attached 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: 0˚C ~ 40˚C (32˚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.
