IMPRES Battery Initialization
For full IMPRES functionality, a new IMPRES battery or IMPRES 2 
battery must be initialized by the charger. The charger automatically 
detects the new IMPRES or IMPRES 2 battery, and automatically 
starts Initialization. Initialization is the first IMPRES battery Calibration/
Reconditioning. This is a two-phase process. The first phase is Battery 
Discharge, indicated by the Status LED in Steady Amber. The second 
phase is full charge, eventually indicated by Steady Green LED. 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.
Automatic IMPRES Battery Calibration/Reconditioning
The IMPRES 2 charger automatically assesses the condition of an 
IMPRES or IMPRES 2 battery. Based on this condition, the charger 
automatically calibrates/reconditions the battery. Interruption of either 
the discharge phase or the full charge phase delays Calibration until 
the next charging opportunity. Calibration/Reconditioning may be 
enabled or disabled using Charger Setup Mode. When disabled and 
the IMPRES battery requires Calibration/Reconditioning, the LED 
indicates Alternating Amber/Green at battery insertion and after the 
battery is charged.
Manually Initiating Calibration/Reconditioning
Though Calibration/Reconditioning is automatic, there may be 
situations in which manual initiation is desired. To manually initiate 
Calibration/Reconditioning, remove IMPRES or IMPRES 2 battery from 
the charger. Then, perform the following steps:
1. Insert the battery into the charger pocket.
2. Within 2.5 minutes, remove the battery from the charger pocket.
3. Within five seconds, reinsert the battery into the charger pocket.
Calibration/Reconditioning starts immediately, typically beginning with 
Battery Discharge (Steady Amber). Calibration/Reconditioning is 
complete only after full charge (Steady Green).
