IMPRES Batteries and Chargers

The IMPRES™ energy solution is an advanced energy system developed by Motorola Solutions. The system includes:

IMPRES battery
IMPRES adaptive charger
IMPRES radio

Charger Specification

Input: 14 V 1 A
Output: 8.8 V 1.5 A

Features and Benefits
Charging IMPRES batteries using an IMPRES Adaptive Charger, which periodically calibrates and reconditions the battery, yields the following benefits:

Maximize battery life by significantly reducing heat during the trickle and post-charge cycles.
Determines the current battery status, giving the radio user an indication of effective use time.
Provide higher-rate IMPRES Lithium-Ion battery charging.
Automatically performs calibration and reconditioning when needed.
Minimizes IMPRES battery heating, regardless of how long the battery is left in the charger pocket.
Periodically charges a battery stored in the charger, 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 life cycle.

Using this unique patented system, there is no requirement to track and record IMPRES battery, conduct manual calibration and reconditioning, or remove batteries from chargers after charging completion.
Charging Radios and Batteries

The IMPRES Adaptive Charger System is a fully automated system. The charger pockets accommodate either a radio with an attached Motorola Solutions- approved battery, or a Motorola Solutions-approved battery alone. Batteries charge best at room temperature.
Prerequisites: Note that the radio can only be turned on when the radio is transmitting data wirelessly. Otherwise, turn off the radio.
Procedure:

Plug the charger end of the power supply cord into the DC inlet (1) at the back of the charger.
Plug the wall power adapter into the appropriate Alternating Current (AC) outlet.
A successful power-up sequence is indicated by a single green blink on the charger indicator. Refer to the IMPRES Battery Charging Indicators on page 9.
Insert a Motorola Solutions-approved battery, or a radio with a Motorola Solutions-approved
battery into the charger pocket.
- Align the battery contacts with the charger contacts.
- Press the battery into the pocket, ensuring complete contact.
  Once the Motorola Solutions-approved battery is properly seated into the pocket, the charger indicator illuminates, indicating the charger has recognized the presence of the battery.
To remove a radio or Motorola Solutions-approved battery from the charger, pull straight up until the battery completely clears the charger housing.

IMPRES Battery Charging Indicators

Table 1: IMPRES Battery Charging Indicators

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 IMPRES Battery Charging Indicators on page 9.
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.

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 IMPRES Battery Charging Indicators on page 9.
This process can take up to 12 hours or more to complete, depending on the charging status and battery capacity. Interruption of either the discharge phase or the full charge phase delays calibration until the next charging opportunity.
Figure 1: Self-Calibration and Recondition Icon

NOTE: IMPRES batteries with the Self-Calibration and Recondition icon on the battery label, do not require periodic calibration and recondition, when docked into this IMPRES charger.

Terminating Calibration and Recondition Manually
You can manually terminate calibration and recondition during the process.
Procedure:

Remove the battery from the charger pocket.
Reinsert the battery into the charger pocket within 5 seconds.

Battery calibration and recondition immediately terminate. Normal battery charging starts. The LED indicates charge status.

Initiating Calibration and Recondition Manually
Although calibration or recondition is automatic, you may be required to manually initiate calibration or recondition in certain situations.
Procedure:

Insert the battery into the charger pocket.
Remove the battery from the charger pocket.
Reinsert the battery into the charger pocket within 5 seconds.

Calibration and recondition start immediately, beginning 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 IMPRES Battery Charging Indicators on page 9.
NOTE: This process can take up to 12 hours or more to complete, depending on the charging status and battery capacity. Interruption of either the discharge phase or the full charge phase delays calibration until the next charging opportunity.

IMPRES End of Service Life LED Indication

The IMPRES charger may indicate IMPRES battery end of service. Alternating red and green LED status can appear to show End of Service Life.
Normal usage of the batteries reduces the available capacity. After a successful completion of calibration and recondition, IMPRES charger compares IMPRES battery capacity to the battery rated capacity. When the capacity is at a low value, the IMPRES battery may be nearing its end of service.
