IMPRES 2 and IMPRES Batteries and Chargers

Features and Benefits

The IMPRES 2 energy solution is an advanced Tri-Chemistry energy system developed by Motorola Solutions. This system includes:

1. IMPRES 2 and IMPRES Batteries 2. IMPRES 2 Adaptive Charger 3. IMPRES Radios

Charging IMPRES 2 or IMPRES batteries using an IMPRES 2 Adaptive Charger, which periodically Calibrates / 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 / 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.

Using this unique patented system, there is no need to track and record IMPRES 2 or IMPRES battery use, conduct manual Calibration/ Reconditioning, or remove batteries from chargers following completion of charge.

IMPRES 2 or IMPRES Battery Initialization

For full IMPRES 2 or IMPRES functionality, a new IMPRES 2 or IMPRES battery must be initialized by the charger. The charger automatically detects the new IMPRES 2 or IMPRES battery, and automatically starts Initialization. Initialization is the first Calibration / Reconditioning of an IMPRES 2 or IMPRES battery. This is a twophase process. The first phase is Battery Discharge, indicated by a Steady Amber LED. The second phase is full charge, eventually indicated by a 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.

IMPRES 2 or IMPRES Pocket-to-Pocket

When charging IMPRES 2 or IMPRES batteries, the IMPRES 2 or IMPRES charger records charging information within battery memory. If the IMPRES 2 or IMPRES battery is removed from one IMPRES 2 or IMPRES charger pocket and, within 30 minutes, inserted into another or the same IMPRES 2 or IMPRES charger pocket, then charging resumes at the point where charging was interrupted. This feature prevents battery over-charging and minimizes the loss of cycle life. This is especially important when charging Nickel batteries.

Automatic IMPRES 2 or IMPRES Calibration/Reconditioning

The IMPRES 2 charger automatically assesses the condition of an IMPRES 2 or IMPRES 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 Reconditioning Switch. When disabled and the IMPRES 2 or IMPRES battery requires Calibration / Reconditioning, the LED will indicate Alternating Amber / Green at battery insertion and after the battery is charged.

Note: The IMPRES 2 or IMPRES battery must be outside an IMPRES 2 or IMPRES charger pocket for more than 30 minutes for automatic Calibration/ Reconditioning.

Manually Initiating Calibration / Reconditioning

Though Calibration / Reconditioning is automatic, there may be situations in which manual initiation is desired. For example, the IMPRES 2 or IMPRES charger may be indicating Alternating Amber / Green for the IMPRES 2 or IMPRES battery, because Calibration is disabled in the charger. If within 30 minutes that battery is moved to an IMPRES 2 or IMPRES charger that has Calibration enabled, the last charging state will resume, preventing automatic start of Calibration / Reconditioning.
To manually initiate Calibration / Reconditioning, ensure that the IMPRES 2 or IMPRES battery is removed from the charger for more than 2-1/2 minutes. Then, perform the following steps:

1. Insert the battery into the charger pocket
2. Within 2-1/2 minutes, remove the battery from the charger pocket.
3. Within 5 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).

IMPRES 2 or IMPRES End-of-Service-Life LED Indication

The IMPRES 2 charger may indicate IMPRES 2 or IMPRES battery End-of-Service (Alternating Red/Green) upon successful completion of Calibration / Reconditioning.
As batteries are used, normal wear reduces available capacity. At the successful completion of Calibration / Reconditioning, IMPRES 2 or IMPRES chargers compare IMPRES 2 or IMPRES battery capacity to the battery Rated Capacity. When the capacity is at a very low value, the IMPRES 2 or IMPRES battery may be nearing its End of Service. The IMPRES 2 or IMPRES battery remains usable. In some scenarios, it may be desirable to deploy the battery to someone who does not require large battery capacity to complete a work shift.

Manually Terminating Calibration / Reconditioning

At any time during IMPRES 2 or IMPRES battery discharge (Steady Amber), Calibration / Reconditioning may be terminated by performing the following steps:

1. Remove the battery from the charger pocket.
2. Within 5 seconds, reinsert the battery into the charger pocket.

Battery discharge immediately terminates, and normal battery charging starts. The LED indicates Charge Status.

Reconditioning Switch

The charger is equipped with a switch on the bottom of the unit that can be utilized to manually terminate the reconditioning process (as a systemic, on- going use-case). However, the charger will continue to provide an indication that the battery needs to be reconditioned. Switch the RECONDITION to “ON” located at the bottom of the charger to enable the recondition feature.

Troubleshooting

The IMPRES Adaptive Charger incorporates the features of:

• A universal input power supply
• A constant current rapid charger
• A negative pulse conditioning charger
• A reconditioning unit
• A 2-USB Type A Power Outputs
• A user selectable on/off switch for turning ON/OFF reconditioning.

The combination of the features listed above are unique in a desktop charger. Therefore, operation of the radio with a battery attached while in the charger is not recommended. During the charging process, radio operation may result in minimally reduced radio performance and extended battery charge time. During the reconditioning process, the battery becomes fully discharged. As a result, the radio may shut down during reconditioning mode. It is recommended that the battery be calibrated without radio attached or the attached radio to be turned off. When troubleshooting, always observe the color of the LED.

Table 2: Troubleshooting

• Charger contact is not being made.
• No power to the charger.

| Check that the radio with battery, or the battery alone, is inserted correctly.
