Power tools are one of the best inventions as these allow people to complete their projects within minutes.
The devices ensure that you can work much more efficiently as they come with motors that can deliver high power.
Though, it is best that you first learn how the tools can be handled. This helps in preventing problems later on, as power tools can be quite difficult to handle.
However, there is not a single unit on the market that can work without a functioning battery. With every battery pack, you’ll have to pair up the unit with a reliable charger.
Why Is My Hart Battery Charger Blinking Red?
So, brands like Battery Tender and Hart seem to be pretty good when you can’t afford to lose any performance from your devices.
With that being said, you should note that companies like Hart Tools have several lineups that you can choose from.
The cordless power tool series have tons of options that you can select between. People sometimes complain, “Why is my Hart battery charger blinking red?”.
If this is worrying you, then going through this article should help you in getting rid of the issue.
This is because we will be providing you with troubleshooting steps as well as some major reasons for the problem.
- Battery Not Installed Properly
The LED light on Hart chargers can blink in different colors to identify what the device is doing. If this is blinking red, then it means that your battery might be faulty.
Though, before you get into this, it is important to check if the battery is installed properly.
Sometimes people might have accidentally taken off the batteries and then forgot to install them back in tightly.
Alternatively, dust particles might have clogged the connection for your batteries which might be preventing them from functioning.
Whatever the case might be, you should remove the battery by holding the small button above it and then sliding it down the compartment.
After taking out the battery, clean the connections and ensure all the clogs have been removed. The user can then install the battery back in and see if it gets charged or not.
- Water Damage To The Unit
Water damage to the charger might be the case here. If you’re sure that the battery is installed perfectly and there are no connection errors, then check for water damage.
The situation around the workshop can get rough from time to time. However, you have a shot at fixing this problem.
All you need to do is to remove the charger from the power outlet and then put it in direct sunlight for a few hours.
That should be enough to evaporate the liquid on the charger. From there, you can wipe away the gunk with a fresh cloth.
You should follow this method even if the liquid is a bit viscous. So, just find a dry spot for the unit, and leave the charger for a few hours.
If the damage is not that serious, you have a good shot at fixing the issue with your device. On the other hand, if you are unlucky, then the only fix is to get a fresh piece.
You could try claiming the warranty if the charger was purchased less than 12 months ago. After showing proof of purchase, it won’t be too difficult to get a new unit.
- Voltage Issues From The Main Source
Voltage issues are also pretty common, and you need to isolate the problem with the power source here.
If you’re sure that the unit is in good shape and the battery is also compatible, then the power source is to blame here.
You can check the power source with a voltmeter or a multimeter.
Both of these devices will help you find these errors with the voltage supply.If you’re not too sure about checking the voltage output yourself, then ask an expert for help.
You won’t have to worry about electrocuting yourself that way, and the expert will be done with the issue in no time.
Ideally, you need to get your electrical connections fixed every six months. So, if you’ve yet to isolate the issue, just call an expert.
He will be more than happy to help you through these minor issues with the system. From there, you can check the response from the charger one more time.
- Battery Completely Drained Out
The battery might also be to blame here, and you need to make sure that the battery is not completely drained.
However, if you’ve used up all the charge in the battery, then you will have to jump the battery with a fresh pack. You won’t be able to charge this unit when it is dead.
So, you have to grab a charged battery and then use wires to link up the new battery with the drained one.
Keep the batteries connected for around 40 minutes, and then try connecting them with the charger. That should mostly be enough to help you isolate these errors.
From now on, you need to focus more on not draining the battery completely. Twenty percent battery charge is a good point to aim at.
You should leave the unit when it is at less than 20 percent. Otherwise, you will run into the same errors with the drained battery.
Jumping the battery might seem like a good idea, but it won’t serve you well in the long run.
So, instead of relying on this method, again and again, try to find a better battery that won’t drain out as fast.
- Hardware Issues
The problem with the charger hardware might also be to blame here.
If you’re not too sure about the charger and the issue is not fixed after going through the servicing requirements, then get a new one.
There is no point in wasting your time with a defective charger. Some owners try taking their chargers to a repair center to get them fixed.
However, that is not always the best option. You need to focus more on getting a new device. Otherwise, you’ll just be postponing the issue with the charger.
The upside here is that the warranty is pretty good on these units. If you’re free, it can take a few hours to go through the warranty claim process.
You will just have to show proof of payment and then wait for an official response. From there, you will have a new device within the same week.
- Battery Not Supported
Another reason for this issue can be that the voltage required by your battery or the voltage being outputted by the charger is too high.
Both of these can be dangerous for the devices as there is a high chance of one tool getting damaged.
Considering this, the charger tries to control its voltage to prevent the tools from burning out. This sometimes also result in the charger not functioning at all.
You can fix the problem by using a charger that is supported by batteries. You can find a list of all the supported chargers with different batteries from Hart online.
- Faulty Battery
If the battery is still not working, then there is a high chance that it might be faulty.
This can be quite annoying to deal with, but you should note that there are two options that you can go with.
One of these includes getting the battery replaced with a new one. When it comes to this, people should understand that these batteries usually lose their charge over time.
On the other hand, if your battery got damaged too soon, then something might be wrong with it. You can usually get a free replacement from Hart Tools in cases like this.
Wrapping Up
Going through these reasons will help you understand why your Hart charger is blinking red. Most of the time, it is the battery.
However, there is no harm in checking the condition of the unit and improving the power connection.
Make sure to check the current condition of the contact points and the hardware status.
If any of the components are damaged, make sure to get a new charger. Similarly, you will need to get the outlets fixed if the power flow from the device is not optimal.
It all comes down to the current condition of the device, and you need to inspect it thoroughly. From there, it is not hard to get the battery pack to charge.
My battery is blinking red I have only used it twice this is ridiculous the price I paid for this stuff.. will not charge at all… I have a 40 volt battery from Hart won’t be buying this equipment again if its this difficult to use… From Suzanne
One possibility you didn’t mention is the battery may be too hot to charge. If this is the case, normal charging should resume after it cools down.
