Why Milwaukee Battery is not Charging
If you are among those who are frustrated due to their Milwaukee battery not charging, let this not worry, others are also facing the same problem.
These people who seek assistance with Milwaukee batteries often experience the same problems with their batteries as any other batteries often do. Good thing you have few choices before taking the long time to buy a new battery.
Milwaukee Battery Not Charging
Milwaukees Battery
Make sure outlet you are using is working
Try the most simple verifier of the problem i.e. make sure that the charger is connected to a power socket. Plug a device that is different with this outlet and turn it on to see if it’s working well. If the charging port appears to be faulty, plug-in the
charging cable in a different port, to see if the charging light lights up when the battery is connected to the charger.
There can be a hidden complexity with this apparently straightforward, yet it can be the one. The easiest issues are often the ones related to the circuit fuse that has been blown off or the damaged power outlet. It may sound trivial, but do not skip the step and it will help to save some time and work.
When the outlet is not working, it loses the ability to power the charger, making the charger incapable to draw out the electric. Therefore, open the outlet and try other devices like charging the phone charger to check whether have attained power there.
Oh you found out that your plug is working. It seems like, though, the battery did not charge. It is fortunate that we have the option to resolve the issue through other means! Secure Milwaukee’s superior charger through a simple click.

Press the button on the battery when plugging in
Don’t forget that you need to press those red buttons and they slide down as the battery gets the charger. This guarantees that positive and negative connection points of the battery and charger are in appraisal. You will still get a solid “go green” light when charger is inserted whenever the process is done inappropriately but the battery has not been recharged.
Two red buttons and charger cable to be found on the side of Milwaukee battery with Milwaukee was a display of simple and self-evident design.
√ When battery is put on charger, it’s time to push red buttons on charging station.
Otherwise, the battery will not get the full charge. In this case, instead of charging, it will just be sitting and taking the space on the charger. When these are done it will mislead users to find the battery is fully charged. The charger will illuminate in a bright GREEN light if it is fully charged or it will be lit in the same way when it is truly full (just as it would with a perfectly charged device).
This is a situation where the display shows that you have a full charge on your battery and then after a few short minutes the power shuts off. This could be an indication that the battery doesn’t lie flat on the charger cable correctly.
Please be aware that if the battery is not full, there will I will show a solid red light on the plug when the battery is connected to the charger.
Below is a guide to the charging lights that you will see on a Milwaukee charger
Symbols that represent lights on the Milwaukee charger
- Solid RED light: Battery is charging
- Solid GREEN light: Battery is fully charged
- Blinking RED light: battery is too hot or too cold
- Blinking RED and GREEN lights (simultaneously): Damaged or faulty battery
Unplug the charger and wait 10 seconds
If the flash is really there, when you will put the charge in and the flashing red and green LED lights will this be a quick and an easy way to fix the charger reset it.
Slides down the sleeve to find the battery, thus carefully disconnecting it. Sometimes after the battery removal the light will still be on, but less bright. Milwaukee suggests taking down the charger from the connection to the source of power until the light indicator stops. Normally, it will take around 7 -10 seconds for the yellow lights to happen.
Unplug Milwaukee charger from the outlet
Replace the battery cable connection to the power source by plugging the other end of the charger cable into the power outlet. And then you can slip over the battery bar (you’ll hear a click sound). If the light changes from green to red and remains solid, then the battery is being charged.
When light signs green and red continue to blink, skip to the next sequence!
Clean the connections of dirt and debris
If there is dirt on the terminals of the battery and or charger, this will not allow for a good connection. This interruption in the connection will not allow the battery to charge.
The terminals seen above, on both the battery and charger must be clean and free of debris in order to maintain a solid connection.
Often the debris will be visible (dust, corrosion, dirt, etc). However sometimes they may appear clean but in fact there is enough “gunk” in there to disrupt the connection.
It is important, if the terminals appear clean and nothing is standing out, “STILL DO NOT SKIP THIS STEP”. There is absolutely no harm in cleaning out the terminals and it may solve the issue.
The terminals on the charger are bigger, and in my experience much easier to clean. I use a Q-tip and some rubbing alcohol. You want to make sure you hit both sides of the terminal with the Q-tip.
The terminals on the battery are much smaller and harder to get into. For this I have found either an envelope or sand paper folded over does the trick. You want to use something that will be firm enough to not crinkle or loose its shape when you slide it in the slits. I have also found you can dip the sandpaper or envelope in rubbing alcohol to enhance the clean.
Often if using a white material you will actually see the black soot coming off as you stick it in the slits.
Once you have cleaned all the terminals (on the charger and battery), try plugging the battery back in. You should see a solid red light on the charger, if the battery is charging.
This is a quick and easy fix that is good to get in the habit of doing every couple of months. No matter where you store the battery/charger, debris will build up. It is important to keep the ports clean in order to maintain a quality connection.
Slowly charge the battery for 2-3 minutes at a time
If a battery gets below a certain voltage, it can become flat. If that is the case, you can try charging the battery for 2-3 minutes at a time for a total of about 30 minutes. You can think of this as a way to jump start your battery.
Think of a flat battery as being fully dead. When this happens it cannot hold a charge so by putting it on the charger for shorter bursts will help kick start it back to life. Usually after about 30 minutes of these short bursts, the battery will have enough juice that it can now be fully charged. Again a solid red light on the charger will indicate if this fixed the issue.
If these steps have not worked to get your Milwaukee battery charging, there is one final thing you can try before contacting Milwaukee.
Use speaker wire to connect dead battery to a healthy battery
If you have tried all the other steps and the battery will still not charge. Then you can try and kick start the battery with some speaker wire.
In older Milwaukee batteries (that do not have an indicator light) it can be difficult to determine if a battery is fully dead. The best indicator is if you put the battery on a tool and you get absolutely no power. With newer Milwaukee batteries that have the indicator light on the front. You can determine a battery is dead if you press the indicator button and no lights come on.
In this case a couple things may have happened. As described above, the battery may have gone flat. Or the battery was so depleted that it went into sleep mode. If this happens, the battery will not even register when placed on the charger. So we need to give it a jump start, just like a dead car battery.
In order to perform this technique, you need to have a fully functioning and charged Milwaukee battery.
It is important to note, that on every Milwaukee battery there is a positive side labeled “+”, and a negative side labeled “-“.
Place the two batteries next to each other. Take some speaker wire with the covering removed at the ends so the wire is exposed. Connect the “positive” terminal on the healthy battery to the “positive” terminal on the dead battery (+ terminal). Then take a another piece of wire and connect the “negative” terminal on the healthy battery to the “negative” terminal on the dead battery (- terminal). Make sure that you stick the exposed wire deep in the terminal so it maintains contact with the metal.
Using speaker wire to connect positive on dead battery to positive on charged battery and negative on dead battery to negative on charged battery
Using speaker wire and metal to connect the battery terminals
Hold the wires in place for about 15 minutes. That should provide enough “juice” from the healthy battery to jump start the dead battery. Then disconnect the wires. Now try placing the dead battery on the charger. It should indicate that a charge is in progress (solid red light).
