Motorola IMPRES 2 User Manual page 8

There are additional advantages when charging an IMPRES 2 Lithium-
ion battery with an IMPRES 2 Adaptive Charger:
• Higher-rate IMPRES 2 Lithium-ion battery charging.
• Faster charging.
• Extended life cycle.
This feature combination is unique in a desktop charger. Therefore,
operation of the radio with a battery attached while in the charger is not
recommended.
During the charging process, radio operation may result in minimally
reduced radio performance and extended battery charge time.
During Calibration / Reconditioning, the battery is fully discharged
before being fully charged. As a result, the radio may shut down during
the discharge phase.
