Motorola IMPRES Battery Tips and Charger Indicator Lights | Magnum Electronics, Inc.
A Motorola IMPRES battery must be initialized by an IMPRES charger the first time it is charged. This process is indicated by a STEADY YELLOW light on the charger indicator (the same as if the battery were reconditioning). The process is automatic, includes an initial reconditioning of the battery, and begins charging upon completion of this process.
This process requires approximately 12 hours depending on the capacity. Do not remove the battery from the charger until the STEADY GREEN light is on.
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.
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.
Within 2-1/2 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.

How long does a Motorola impres battery last when fully charged using a Motorola charger.
Currently we can only get 3 hours of talk time.
Justo, your battery should provide a minimum of 8 hours. What radio are you using and what is the 3 digit date code on your battery?
I have an Impress charger and I am using a standard Motorola battery, Could I use the same procedure for an Impress battery as I would a standard battery to force battery conditioning?
Non-Impres batteries will charge in an IMPRES charger but will not condition.
It can take up to 14 hours for high capacity batteries. The process drains your battery to 0% and recharges it to full capacity. This calibrates the battery gauge and eliminates any memory effects from past use.
If you leave a battery in the charger after it has been fully charged, Will this deteriorate the battery, especially if the battery is left in the charger for hours and or days.
IMPRES batteries can be left in IMPRES chargers for long periods with no deterioration. The green light is an OFF indication but the charger will communicate with the battery every few minutes to determine if it needs to be charged.
I have an Impress charger and battery. When the battery is seated in the charger, the light flashes yellow to red. Is there a problem with the charger?
I have an Impres WPLN4121BR V3.90 . With no radio in pocket charger it flashes red. What is the issue?
We suspect the microprocessor has failed. The manual does not provide any troubleshooting tips for your problem. The charger base is not repairable and should be replaced assuming you tried a different power supply cord.
My company has bought 5 radios with impres charger and 15 impres batteries. They has been around 10 mounths stopped because some issue with the compatibilities of the frecuences.After this period when I traied to charge the new batteries only 5 of them could be charged, the rest remain for hours with the Red light flashing. Any recomendation?
Keep them in the charger for at least 48 hours. If they do not change to solid red return them for a warranty replacement.
I have a similar problem, 11 out of 20 batteries don’t charge. They just flash red…. and because of our geographical location it hasn’t been financially feasible or efficient time wise to return them from Africa to our UK base to be returned to the vendor.
We have never experienced that type of failure rate. You might need to check the charger firmware.
There is no need to purchase an IMPRES 2 charger. IMPRES 2 batteries and IMPRES 2 chargers are are backward compatible with original IMPRES. The only exception is some original IMPRES chargers do not support Li-ion chemistry. Blinking “RED” indicates poor contact or not chargeable. Try cleaning the battery contacts with an eraser.
Would it be correct to charge an IMPRES battery in the non-IMPRES charger?
Yes…no harm will be done, however conditioning will not occur.
If the conditioning was not done will it lose its useful life faster?
Conditioning is recommended for longer life and charging cycles.
I have the same charger in the picture above. Normally in the past when I have placed my battery on the charger it is a steady red light. Usually after about an hour the light will start flashing green which flashes for about 30 min before being fully charged. Recently I have noticed that when I place it in the charger it still will indicate a steady red light, but instead of going to flashing green it goes to steady green. Last night I placed it in the charger and again steady red light. It was on the charger for about 2-3 minutes and then went to steady green. What does that mean when it does that? I have a Motorola XTS-1500 radio and I always wait until the radio starts chirping before charging.
What is the model number of the battery and 4 digit code on the label?
The only one I see is AP-9858.
That looks like an aftermarket model number. The battery probably needs to be reconditioned.
OK. Thanks for the suggestion.
I just buy a impres battery for Motorola XTS3000. After I charged the battery for a moment the light at charger is flash with red and green. After I take the battery out time of use is just for 10 hours. It is always like this. What is a problem with a battery or charger and How can I do?
If the charger is flashing red/green it indicates the battery is near the end of it’s life.
Do you do any damage to the life of the battery if you leave batteries in an Impres charger until you need them? Thank you!
IMPRES batteries can be left in IMPRES chargers for long periods of time unlike other chargers. Green light turns OFF trickle charge and heat that breaks down battery chemistry. IMPRES technology will check battery level and top off when needed.
We have a number of batteries and after we place in the charger, the light goes green and the display reads – charge complete – 70% capacity. Of course the batteries are not lasting very long.
Is there anything we can do to recondition them here or do they have to go back to manufacturer ?
If your charger is more than 2 years old check the firmware version and update. It is stamped on the bottom of the charger. An IMPRES tool is required to perform the upgrade.
Hi there. I have a PMNN4547A 1834 AT23 battery that is brand new. The battery was initialized in an Impres charger and has only been cycled three times. After the initial charge and ever since, the battery flashes low battery and the radio will not read the battery data for approximately twenty minutes from when the radio is turned on. After that time, the radio then displays the battery’s capacity. Any insight into what is going on? Thanks!
Have you checked to make sure you have the latest radio firmware?
I’ve not. Will have to ask that of our vendor when he’s around. Thanks!
I have a single slot Impres charger like the picture at the top of the page. When I first got my radios (used), I ran a conditioning on the batteries and documented the # of charges and capacity percentage (most of them were over 100%). I now do not remember how I got that information, since there is no display on the charger. I think I used the “BATT” display on my XTS5000, but I don’t remember how I got it to show the +100% capacity (when I do it now, it only shows full at 100%…I can’t remember how I got the actual capacity info). Can you remind me how to see that?
I have PMNN4412AR batteries and recently purchased its charger from market but when placing on charger its green led lights up and not charging the battery. I have asked vendor and he checked the charger on his battery which is working and charger showed red color on placing and green on full charge.
can you guide what is the issue?
