Two Way Radio Battery Management Guide

Our complete guide to help maintain your IMPRES batteries.

What is a Motorola Solutions IMPRES Battery? 

Designed by Motorola solutions for their two-way radio equipment, IMPRES batteries provide automatic, adaptive reconditioning, end-of-life display and other advanced features. Data is stored in the battery and communicated to the charger via a unique IMPRES communication.

When purchasing or hiring two-way radios there are options to upgrade your batteries to a specialist Motorola IMPRES battery & charging system *comes standard with hire equipment.  These specialist batteries can be paired with an intelligent battery/charger system that will identify the current status of the battery and indicate it by the LED colour on the charger pod. This is the same on both the single charger and six-way charger.

A key is for the lighting sequences are found underneath single chargers and on the top of multi chargers.

We have highlighted in the below chart what the key indicators mean on your chargers.


IMPRES Automatic Battery Conditioning

Motorola IMPRES Adaptive Chargers, when used in conjunction with a Motorola IMPRES battery, have the ability to determine the appropriate time to recondition the battery. When an IMPRES battery is properly inserted into the charger, the charger determines if it is appropriate to recondition the battery. If the battery needs reconditioning, the charger automatically indicates a STEADY YELLOW.This process may take up to 12 hours to complete, depending upon the state of charge and capacity rating of the battery when it is inserted. It is important to note, for this process to be effective, the IMPRES battery must be allowed to complete the recondition/recharge process. Leave the battery in the charger until the charger indicates a STEADY GREEN. At the completion of the recondition cycle, the charger automatically recharges the IMPRES battery.

How to Terminate the IMPRES Conditioning Process

At any time during the reconditioning process of a Motorola IMPRES battery (STEADY YELLOW indication), reconditioning may be terminated by removing and reinserting the battery back into the charger within 5 seconds. This causes the charger to terminate the reconditioning process and begin the charging process. The charger indicator changes to a STEADY RED. The charger will attempt to recondition the battery at the next battery insertion.

Manually Initiating the IMPRES Reconditioning Process

Within 2 ½ minutes of the initial insertion of an IMPRES battery (STEADY RED indication), remove and reinsert the battery within 5 seconds to manually force reconditioning to occur. The charger indicator changes from a STEADY RED to a STEADY YELLOW. This forces the charger to recondition and automatically recharge the battery. This is a useful feature to have when IMPRES batteries have been in storage for several months or longer. Two or three manual recondition cycles may be required to rejuvenate the batteries, due to long-term storage conditions.
