Automatic IMPRES 2 Battery Calibration
The Motorola Solutions IMPRES 2 Adaptive Charger is able to determine when to calibrate the battery when
used with a Motorola Solutions IMPRES 2 battery.
NOTE: The radio charging pocket does not perform the calibration process.
The IMPRES 2 battery must be outside from the IMPRES 2 charger pocket for more than 30 minutes for an
automatic calibration and recondition.
When an IMPRES 2 battery is properly inserted into the charger, the charger determines if it is appropriate to
calibrate the battery. If the battery needs calibration, the charger automatically indicates a steady amber. This
process may take up to 12 hours or more to complete, depending on the state of charge and capacity rating
of the battery when it is inserted.
For this process to be effective, the IMPRES 2 battery must be allowed to complete the calibration or
recharge process. Leave the battery in the charger until the charger indicates a steady green. At the
completion of the calibration cycle, the charger automatically recharges the IMPRES 2 battery.

End-of-Service-Life Indication
The IMPRES 2 charger may indicate IMPRES 2 battery end-of-service by alternating red and green LED
upon successful completion of calibration or reconditioning. For battery with Self-Calibration icon, the charger
may indicate the battery End-of-Service momentarily at battery insert, and continuously blinks red and green
LED upon complete charging.
When batteries are used, normal wear reduces available capacity. IMPRES 2 chargers compare IMPRES 2
battery capacity to the battery-rated capacity. When the capacity is at a very low value, the IMPRES 2 battery
may be nearing its end-of-service. The IMPRES 2 battery remains usable. In some scenarios, it may be
preferable to deploy the battery to someone who does not require large battery capacity to complete a work
shift.
