IMPRES Battery Initialization
For a full IMPRES functionality, a new IMPRES battery must be initialized by the charger.
The charger automatically detects the new IMPRES battery, and automatically starts initialization.
Initialization is the first calibration and reconditioning of an IMPRES battery.
Phases of Battery Initialization
The first phase is a battery discharge, indicated by a steady amber LED. The second phase is a full
charge, indicated by a steady green LED. Refer to
NOTE: This process may take up to 12 hours or more to complete, depending on the state of
charge and capacity of the battery. Interruption of either phase delays initialization until the next
charging opportunity.

IMPRES Pocket-to-Pocket
When charging IMPRES batteries, the IMPRES charger records charging information in the battery
memory.
Charging can resume if the user remove IMPRES battery from one IMPRES charger pocket and within
30 minutes, insert it into the same or a different IMPRES charger pocket.
1.5
Automatic IMPRES Calibration and Recondition
The IMPRES charger automatically assesses the condition of an IMPRES battery.
Based on the condition, the charger automatically calibrates and reconditions the battery. This process
starts with battery discharge, indicated by a steady amber LED status. Calibration and recondition
are complete only after a full charge, indicated by a steady green LED status. See
