NEVER put the battery in a microwave oven,high-pressure container, or in an induction heating cooker.This could cause a fire, overheating, or cause the battery torupture.• CAUTION! Always use the battery within the specified tem-perature range for the transceiver (–10˚C to +60˚C; +14˚Fto +140˚F) and the battery itself (–10˚C to +60˚C; +14˚F to+140˚F). Using the battery out of its specified temperaturerange will reduce the battery’s performance and battery life.• CAUTION! Shorter battery life could occur if the battery isleft fully charged, completely discharged, or in an excessivetemperature environment (above +45˚C; +113˚F) for an ex-tended period of time. If the battery must be left unused for along time, it must be detached from the radio after discharg-ing. You may use the battery until the battery becomesabout half-capacity, then keep it safely in a cool dry placewith the temperature between –20˚C to +35˚C (–4˚F to+95˚F).DD Charging caution• R DANGER! NEVER charge the battery pack in areas withextremely 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!

NEVER insert the transceiver (battery attachedto the transceiver) into the charger if it is wet or soiled. Thiscould corrode the battery charger terminals or damage thecharger. The charger is not waterproof.• CAUTION! DO NOT charge the battery outside of the spec-ified temperature range: 10˚C to +40˚C (+50˚F to +104˚F).Icom recommends charging the battery at +20˚C (+68˚F).The battery may heat up or rupture if charged out of thespecified temperature range. Additionally, battery perfor-mance or battery life may be reduced.
