Dremel makes some of the smartest portable tools that can be used for a number of applications, and you don’t have to worry about a single thing while you are using any one of these.

Yet, there are certainly a number of factors that you will need to keep in mind to have the perfect utility for these tools.

Battery chargers are arguably one of the most annoying and crucial things to maintain in your workshop. There are simply too many things that can go wrong here.

If you wish to get an optimal response from the battery charger, then it would help if you could keep track of the unit’s maintenance.

There is no point in ignoring the maintenance as you will have to spend money on a new system if you keep on ignoring these issues. 

There are also some battery chargers that you can get to ensure that you are not getting any sort of problems with the charger or your batteries.

Yet, there are several indicators on the charger, and if you are getting a green blinking light on your Dremel battery charger, here is what it means.

Dremel Battery Charger Blinking Green

  1. Green Light Blinking Steadily

The green light that is blinking steadily on the Dremel charger doesn’t mean that there is an error on it at all. It means that there is no problem, and the charger is working just fine.

The green light will start blinking once you connect the battery to your charger and is the signal that your battery has been connected properly to the Dremel battery charger.

Once it starts blinking steadily, you can be assured that the battery is being charged properly, and you don’t have to miss out on anything. 

Just wait patiently until the batter is fully charged and the blinking green light gets stable. That is the indicator that your battery is properly charged now, and with that, you will be able to get it to use for any equipment you might have.

  1. Green Light Blinking fast

The battery charger can also be blinking the green light really fast, and that is an indicator that you are using a battery that might not have balanced cells on it, and the charger is trying to balance the cells.

There can be a number of cells on your battery, and they need to be at the same voltage level, which is 4.2 Volts for most lithium-ion batteries.


That is why you will need to ensure that you are getting it to work, and afterward, there are hardly any problems that you will be facing with the charger not working.

If the battery charger is blinking the green light faster and it is trying to balance out the cells, you will need to give it 5-10 minutes, and that should make it up for you so you can easily charge the batteries with the same charger.

Yet, if the green light doesn’t get steady even after giving it the time to balance those cells, you will need to get that checked since there might be a number of issues, such as a bad battery or some of the cells might have been dead. 

So, you will need to get the battery pack replaced since the lithium-ion batteries are not the best thing to be repaired. So, the best way for you would be to ensure that you are getting a new battery, and that will be the best thing for you.

Here are some more pointers to help you fix the situation with the battery not charging while the Dremel battery charger is blinking green.

  1. Check Power Cord

You should also check on the condition of the power cord to isolate the issue. You can’t really expect the Dremel system to work when the charger does not get the desired power supply from the system.

So, if you’re also stuck in these issues, be sure to check up on the power cord.

From there, you can isolate the issues by replacing the power cord or trying out a new outlet. It is not too rare for the outlet to be at fault here, and you can always test out a new one to figure out what exactly is wrong with the system.

To do that, you also have the option of using devices like a multimeter. That will be more than enough to help you figure out how to adjust the system. Ideally, you should seek help from a professional when you’re running into issues with the power supply. 

There are just too many incidents with owners electrocuting themselves while setting up the system.

So, you need to avoid this risk and rely on a professional from the local hardware store to help with this situation. He will charge you a few bucks, but you will not have to deal with the same errors again.

  1. There Might Be Temperature Issues

Most of the time, the issue is not with the charger but with the battery pack.

So, you need to check on the battery pack to adjust the situation. If the battery pack is too hot to the touch, then you need to leave it for a few minutes before putting it back into the charger.

This is one of the main reasons why experts recommend that you take some breaks while using the power tools. There is simply no point in grinding at the project for hours as you’ll lose efficiency and will negatively impact the lifespan of your devices.

So, all that you need to do here is to fix the temperature by touching the pack. That will mostly be it, and you can cool up the unit at room temperature before placing that in the charger one more time. 

Similarly, you need to also check on the alignment of the battery contact points with the charging terminals and then make sure that they are engaged properly. There should be no gaps or foreign objects in between that can impact the power flow.

From there, you can easily adjust the system without worrying about more errors down the road.

  1. Try Jumping The Battery

Lastly, if the battery is completely discharged, you will not be able to get any response out of the unit.

Even if the charger is blinking green, the battery will not pick up any charge when it is completely out of juice. So, all that you need to do is to check up on the system.

Your main focus here should be on jumping the battery here with a charged pack. You can simply grab a pair of wires and then check up on the system one more time.

Jumping the system with a pair of wires is not an extensive task, and leaving both battery packs connected for 20 minutes will do the trick.

From there, you can put the discharged battery pack back into the charger and leave it to charge for a few more hours.

Ideally, you will not have to bother with more errors, and the battery will start picking up the charge without more compilations.

On the other hand, you can also reach out to Dremel customer support for help.

You don’t need to go through all of these fixes on your own. Instead, seeking professional support will help you save a few hours here and there as you try to figure out the situation.

These experts will not only help you narrow down the cause of the issue but will also guide you through all of the relevant fixes.

Even if you have no experience in troubleshooting these systems, Dremel customer support will ensure that you will not have to deal with more errors down the road.

Hopefully, it won’t come to all that, and the issue will be fixed as soon as you adjust the power supply to the charger.

Wrapping Up

The situation with the green light blinking on the Dremel battery charger doesn’t point toward any issues. However, if you can’t seem to get your battery to charge even after several hours, then there might be a fault in the system.

You will need to check up on the battery status as well as the charger hardware to figure out the issue.

There might be problems with the battery’s temperature, charging levels, the condition of the contact points, and much more. So, you’ll have to do a bit of troubleshooting to figure out the situation.

From there, you can also take a peek at the charger for water damage and terminal issues.

All that you’re trying to do is make sure that the power can flow from the charger to the battery pack. So, be sure to keep that in mind and test out the system accordingly. 

However, if you’re unsuccessful even after going through all of these steps, then you need to reach out to an expert.

Just explain your end by listing all the symptoms and the fixes you’ve tried so far. From there, you’ll be guided through several fixes without dealing with more errors.
