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.
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.
APX NEXT XN battery comes with high temperature detection feature that is detectable from IMPRES
2 charger with software version V2.02 or newer. When this feature is enabled, the status LED
flashes red and green alternately upon charge completion for battery that went through prolonged
exposure (exceeding 10 minutes cumulatively) under extreme high temperature environment. The
charger displays the following:
