Features and Benefits
The IMPRES 2 energy solution is an advanced Tri-Chemistry energy system developed by Motorola
Solutions. This system includes the following items:
• IMPRES 2 and IMPRES batteries
• IMPRES 2 adaptive charger
• IMPRES radios
Charging IMPRES 2 or IMPRES batteries using an IMPRES 2 adaptive charger—while periodically
calibrates or reconditions the battery—yields the following benefits:
• Extends battery cycle life.
• Measures battery capacity, giving the radio user an indication of effective use time.
• Determines the current battery state of charge, giving the radio user an indication of effective use
time.
• Monitors the IMPRES 2 or IMPRES battery usage pattern.
• Updates pattern information stored in the IMPRES 2 or IMPRES battery.
• Automatically performs calibration or reconditioning only as needed.
• Minimizes IMPRES 2 or IMPRES battery heating, regardless of how long the battery is left in the
pocket.
• Periodically "tops off" a battery stored in the charger pocket, maintaining a high state of readiness
for the user.
• Eliminates Nickel battery memory effect, eliminating the need to purchase special equipment or
train personnel in tasks to maintain battery cycle life.
With this unique patented system, there is no need to track and record IMPRES 2 or IMPRES
battery use, conduct manual calibration or reconditioning, or remove batteries from chargers following
completion of charge.
1.3.2
IMPRES 2 and IMPRES Battery Initialization
For full IMPRES 2 or IMPRES functionality, you must use the charger to initialize a new IMPRES 2
or IMPRES battery. The charger automatically detects the new IMPRES 2 or IMPRES battery, and
automatically starts the initialization. Initialization is the first calibration or reconditioning of an IMPRES
2 or IMPRES battery.
Initialization is a two-phase process:
• The first phase: battery discharge, indicated by a steady amber LED.
• The second phase: full charge, eventually indicated by a steady green LED.
This process can 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.
