Motorola IMPRES Charger LED Indicator Guide

Motorola has a line of IMPRES chargers and batteries to help extend the life of your battery, giving you longer runtimes and better charges. The charger will show different LED lights telling you what stage of charge your battery is in.

In this article, we’ll talk about what each LED light indicates and explain a little more about IMPRES.

What does IMPRES mean?

IMPRES batteries by Motorola are designed for simple, reliable care and are equipped with an innovative charging system that when paired with an IMPRES charger, reconditions the battery, extending its life.

The reconditioning batteries are meant to restore it to its normal full capacity. During a recondition, the charger will fully deplete then recharge the battery to eliminate the memory effect.

Benefits of IMPRES Batteries and Chargers

IMPRES reduces the amount of work you have to do with tracking your battery use. All you need to do is place the battery in the charger and remove the battery when done.

Using an IMPRES charger with an IMPRES battery helps,

  • Maximize the operation time between charges with no memory effect. Memory effect often happens when your battery remembers its last charge and discharge cycle, ultimately, decreasing its life cycle every time.
  • Reduce heat during post charge cycles
  • And eliminate the need for additional reconditioning equipment and trained battery personnel.

IMPRES batteries have an internal memory that is read by IMPRES chargers. When an IMPRES battery is charged for more than 2.5 minutes, the charger will read the battery serial number. You can remove the battery from the charger for up to 30 minutes, then once the battery is reinserted into the charger, it will resume the charge from when it was first removed.

What do the Steady Lights Mean on an IMPRES charger?

When using your IMPRES charger, you’ll notice a few different LED lights. Motorola IMPRES charger lights indicate what cycle the battery is in its charging process.

Below is a list of what each solid LED light means on an IMPRES charger. Flashing LED lights, which may be a problem with your battery, are reviewed next.

SINGLE FLASH GREEN: Begin charge. Charger has successfully powered on.

STEADY RED:Battery is in Rapid Charge Mode.

STEADY GREEN:Battery has completed its charge and is fully charged.

STEADY ORANGE (ONLY IMPLIES TO IMPRESS BATTERIES): Your battery is in reconditioning mode. However long your battery remains in this mode depends on the remaining charge of your battery. Fully charged batteries require more reconditioning time (8 hours or more) than fully discharged batteries.

What does the FLASHING light mean on an IMPRES charger?

Your IMPRES charger may flash different colors of green, orange, or red. This may mean your battery is just completing its charge time like normal but other LED flashes may be a warning to the state of your battery.

Below, is a list of what each flashing LED light means on your IMRPES charger.

FLASHING GREEN: The battery has completed rapid charge (>90%) and is now in top off charge.

FLASHING ORANGE: The charger has recognized the battery but is waiting to charge. Battery voltage could be too low or temperature could be too low or too high to allow for charging. When corrected, the battery will start charging.

FLASHING RED: The battery is unchargeable or not making proper contact with the charger.

FLASHING RED/GREENThe battery is fully charged and continues to be usable but may be nearing end of service life. Start looking for replacement batteries if you do not have one already.


IMPRES 1 vs IMPRES 2? Can I use the same charger?

Motorola now has two generations of IMPRES batteries known as IMRPES 1 and IMPRES 2. IMPRES 2 is known as their next-generation system that charges batteries 40% faster and at a higher capacity giving you more talk time. IMRPES 2 also lets you charge 60% more times than a standard Li-Ion battery.

Check your manual to see if your battery is supported with your charger.



While operating your IMPRES battery charger, problems could arise. Below we will talk about each problem and what to do to get your charger working again.

Problem: Charger has no lights

What it means: Charger contact is not being made or there is no power to the charger.

What to do: Check that the battery is properly inserted into the charger. Also, make sure that the power cord is successfully plugged into the charger. If this does not work, Motorola thinks you should replace the fuse.


Problem: Charger flashing red

What it means: Charger contact is not being made or the battery is not chargeable.

What to do: Remove the battery from the charger and place it back into the charger. Remove power from the battery charger and clean with a dry cloth the gold metal contacts of both your battery and the charger. If this does not work, it’s time to replace the battery.


Problem: Flashing orange

What it means: IMPRES Battery is waiting to charge. This could mean your battery is too cold or too hot that it’s making the battery voltage too low for the charge to start.

What to do: When the temperature of the battery is corrected, charging should begin.


Reconditioning IMPRES Battery with Charger

You can either manually or automatically recondition the batteries.

To manually start the reconditioning process, insert your battery into the charger, and within the first 2.5 minutes, remove and reinsert the battery within 5 seconds. This will manually start the reconditioning process. The charger should change from a STEADY RED to a STEADY ORANGE.

To automatically start the reconditioning process,there is no need to do anything. IMPRES chargers are designed to know when it’s time to start the reconditioning process. When it needs to be reconditioned, the charger will show a STEADY ORANGE. When it is done reconditioning the battery, the charger will start recharging your battery.

To stop the reconditioning process,remove and reinsert the battery within 5 seconds. This will end the recondition process and start charging. It should now show a STEADY RED light.
