DeWalt battery not charging is a common issue encountered by users of DeWalt power tools, known for their reliability and endurance. This problem can be particularly frustrating when you’re on a project and your device suddenly stops working, disrupting your workflow.

Lets start understanding what can be the reasons of Dewalt battery not charging below.

Reasons Why Your Dewalt Battery Won’t Charge

Power Issues

Power issues are one of the most common causes behind a DeWalt battery not charging. This could be due to a power outage, a faulty power source, or inconsistencies in the power supply. Therefore, checking your power source and the tool’s connector is recommended to ensure a consistent power connection.

Battery Age and Wear

As with all batteries, the DeWalt battery’s efficiency may decline over time due to age and wear. Continual usage and inadequate maintenance can lead to a decreased battery life and ultimately prevent the battery from charging. It’s advisable to regularly check the battery’s health and consider a replacement if it’s significantly older or shows signs of severe wear.

Charger Problems

Charger problems also account for many cases where a DeWalt battery won’t charge. This could be due to a faulty charger or the charger not being compatible with the battery. Always use the charger that came with your DeWalt power tool or a DeWalt-approved charger.

Environmental Factors

Environmental factors, like temperature and humidity, can also affect a DeWalt battery’s ability to charge. Extreme cold or hot conditions may hinder the charging process, while high humidity can lead to internal damage. Therefore, storing and charging your DeWalt battery under suitable environmental conditions is essential.

Troubleshooting Steps for Dewalt Battery Not Charging

Checking Your Power Source

To determine if the issue lies with the power source, begin by connecting another electrical device to the power outlet you’re using for the DeWalt charger. If the device charges correctly, the outlet is likely not the issue. If the device doesn’t charge, consider switching to a different outlet or having the current one inspected for faults. 

Inspecting the Battery and Charger

Inspect the DeWalt battery for any visible damage or wear, such as corrosion or leakage. If any are found, it’s usually best to replace the battery. Next, examine the charger. Ensure it’s clean and free from dust and debris and that the charging connections are intact. Using a non-compatible charger can also prevent the battery from charging, so using only the charger that came with the tool or a DeWalt-approved one is vital.

Resolving Environmental Factors

To mitigate the impact of environmental factors, always store and charge your DeWalt battery in a dry and temperature-controlled environment. Extreme cold or hot temperatures can impair the battery’s charging capacity. Likewise, high humidity levels may lead to internal damage. If you suspect the battery has been exposed to adverse environmental factors, allow it to acclimatize to room temperature before attempting to charge it again. This step can often resolve any charging issues related to environmental factors.

After following the troubleshooting steps, have you resolved Dewalt battery not charging issue? If not then you have to replace your dewalt battery.

How to Maintain Your Dewalt Battery for Optimal Performance

Proper Charging Practices

It’s crucial to adhere to proper charging practices to ensure your DeWalt battery’s longevity and optimal performance. Always allow the battery to fully charge before using it. Avoid overcharging, as this can lead to diminished battery life over time. Similarly, avoid draining the battery completely before recharging. A good practice is to start charging when about 20% power is left. 

Safe Storage Tips

Storing your DeWalt battery correctly when it’s not in use helps extend its lifespan. The battery should be kept from direct sunlight or extreme heat, as these conditions can lead to degradation. It’s best to store it in a cool, dry place. Removing the battery from the tool when not used can also prevent accidental draining. 

Regular Cleaning 

Regular cleaning of your DeWalt battery and charger can help prevent charging issues. Dust and debris can accumulate on the battery and charger terminals over time, obstructing the connection and preventing efficient charging. Using a dry cloth or compressed air, you can remove this buildup, ensuring a secure and efficient connection for charging. However, please refrain from using liquids or corrosive cleaners as they could cause damage to the battery or charger.
