Hart Battery Not Charging – Reasons and Solutions
There can be several reasons why your Hart 40V Battery Charger is flashing red, indicating that it is not charging properly. Let’s take a look at the most common issues that can cause this problem.
Reason #1: Overheating
One of the primary reasons for a red flashing light on your battery charger could be overheating. This can occur when a battery is charged too quickly or at a higher voltage than recommended, causing it to heat up and trigger the charger’s safety mechanism to shut off charging. If this happens, you will need to let the charger cool down before attempting to charge your battery again. 
Reason #2: Battery Malfunction
Another possible reason for a red flashing light could be a malfunctioning battery. If the battery is damaged or has reached the end of its lifespan, it may not be able to hold a charge properly and can cause the charger to flash red. In this case, you will need to replace the battery with a new one. 
Reason #3: Charger Malfunction
In some cases, the issue may not lie with the battery but rather with the charger itself. A malfunctioning charger can also cause the red flashing light, indicating that it is unable to properly charge the battery. If you suspect this may be the issue, try using a different charger to see if it solves the problem. 
Troubleshooting – Battery Charger Lights
Blinking Red Light
If your Hart 40V Battery Charger is flashing red, it means that there is an issue with the charging process. As mentioned before, this could be due to a number of reasons such as overheating, battery malfunction, or charger malfunction. To troubleshoot this issue, try some of these solutions:
- Ensure that the battery and charger are compatible – using incompatible batteries or chargers can cause issues.
- Check the battery connections – make sure that both the battery and charger connections are clean and free of any debris.

Solid Red Light
Blinking Green Light
A blinking green light on your battery charger indicates that the battery is either almost fully charged or is experiencing a charging error. To troubleshoot, try the following:
- Check the battery connections – make sure they are clean and secure.
- Let the battery cool down – if it has been recently used, let it cool down before attempting to charge again.
- Replace the battery – if the battery is old or damaged, it may not be able to hold a charge properly and will need to be replaced.

Solid Green Light
A solid green light, which indicates a fully charged battery, signifies that it is ready to be used without any concerns. This means that the battery has reached its optimal capacity and is prepared to provide power as needed. If, however, you are facing any difficulties with your battery, such as a sudden drop in performance or unexpected shutdowns, it is important to recognize that these issues might not be directly related to charging. In such cases, it is recommended to address these concerns separately and seek appropriate solutions. 
Quick Fixes for Hart Battery Not Charging
Try Different Power Outlets
Sometimes, the issue may not lie with the battery or charger itself but rather with the power outlet you are using. If your Hart 40V Battery Charger is flashing red, try plugging it into a different outlet to see if that resolves the problem. Faulty or damaged outlets, such as those with loose connections or insufficient power supply, can sometimes cause charging issues. By using a different outlet, you can eliminate the possibility of the problem being related to the power source and determine if the charger itself requires further troubleshooting or inspection. It’s always a good idea to ensure a stable and reliable power supply when charging your battery to maintain optimal performance and prolong its lifespan. 
Use a Multimeter to Test the Battery or Charger
If you have access to a multimeter, it can be an incredibly useful tool for diagnosing charging issues. By testing the battery’s voltage, you can determine if it falls within the recommended range, ensuring optimal performance. Additionally, you can check the output of your charger and compare it to the specified voltage to ensure compatibility. If either of these measurements deviates significantly from what they should be, it could indicate a problem with either the battery or charger. In such cases, it is highly recommended to seek further assistance from a professional or contact Hart’s customer support for expert guidance and troubleshooting. Taking these steps will help you address any potential charging issues and ensure the longevity of your battery and charger. 
Clean the Dust and Corrosion
Dust and corrosion can sometimes build up on battery connections, causing issues with charging. To prevent this from happening, it’s important to regularly clean the battery and charger contacts using a dry cloth or brush. Additionally, you can also use a small amount of rubbing alcohol to remove any stubborn dirt or grime. By keeping the connections clean and free of debris, you can ensure a secure and efficient charging process. This simple maintenance step can go a long way in preventing potential issues and prolonging the lifespan of your battery and charger. 
Power Juice from Other Battery
In situations where the battery is completely drained and unresponsive, you can try powering it up by connecting it to another charged battery. This method, also known as “juicing,” can sometimes provide enough energy to kickstart your dead battery. However, it’s important to exercise caution when attempting this method as incorrectly connecting the batteries could cause damage or pose a safety hazard. It is recommended to only use this as a temporary solution and seek professional assistance for a more permanent fix. By using these quick fixes, you can troubleshoot and resolve any charging issues with your Hart 40V battery and ensure uninterrupted power supply for your tools. Remember to always follow safety precautions when working with batteries and chargers to avoid any accidents or damage. 
Not Fixed Yet (How to reset Hart battery)
If you have exhausted all the aforementioned solutions and find yourself still encountering issues with your Hart battery not charging, it may be worth considering a reset as the next step. Resetting your battery can prove effective in resolving any potential software or firmware-related problems that might be hindering proper charging. To perform a reset, carefully follow these steps:
- Disconnect the battery from any power source to ensure a complete disconnection.
- Press and hold down the power button for a duration of 30 seconds. This extended press helps discharge any residual power.
- Release the power button and allow the battery to remain idle for a few minutes. This idle period allows the internal circuits to reset and recalibrate.
- Reconnect the battery to the charger and attempt to charge it again.
Should the issue persist despite these efforts, you can also try resetting your charger. Begin by unplugging it from the power source and let it remain disconnected for a few minutes. Afterward, plug it back in and attempt to charge your battery once more.
Safety Rules For Charger
When charging your Hart 40V battery, it is crucial to follow these safety guidelines to prevent any accidents or damage:
