When Should You Test Your Charger?
It’s prudent to test your DEWALT charger under several circumstances:
- After experiencing a power outage.
- When the battery takes longer than usual to charge.
- If the battery seems to lose its charge unusually fast.
All these indications could signal that your charger may not be functioning as intended.
Tools Required for Testing
To test your DEWALT Lithium 20V battery charger effectively, gather the following tools:
Essential Tools
- Multimeter: This device will measure voltage, continuity, and other electrical characteristics.
- DEWALT Lithium 20V Batteries: Ensure you have compatible batteries for the test.
- Safety Gear: Eye protection and gloves are essential for safe handling.
Step-by-Step Testing Procedures
Now, let’s explore the testing procedures for your DEWALT Lithium 20V battery charger. These steps will ensure that you can efficiently diagnose any issues.
Step 1: Visual Inspection
The first step in testing your charger begins with a visual inspection.
Inspect the Charger and Cables
- Examine the charger for any physical damage.
- Inspect the power cord for fraying, tears, or any signs of wear.
- Ensure that the contacts on both the charger and battery are clean and unobstructed.
If you notice any significant damage, consider replacing the charger instead of proceeding with further tests.
Step 2: Testing Voltage Output with a Multimeter
Conducting a voltage output test allows you to measure the charger’s efficiency. Here’s how to do it:
Gather Your Materials
Ensure you have the multimeter set to measure DC voltage, and follow these steps:
- Connect the Multimeter:
- Insert the black probe into the COM terminal and the red probe into the VΩmA terminal of the multimeter.
-
With the charger unplugged, connect the charger to the DEWALT 20V battery.
-
Turn on the Charger:
-
Plug the charger back into the wall socket and turn it on (if it’s not already triggered by inserting the battery).
-
Measure Output:
- Touch the black probe to the negative terminal of the charger and the red probe to the positive terminal.
- Read the Voltage: A good charger should output voltage within a range of 20 to 28 volts. If the reading is significantly lower, this indicates a malfunction.
Step 3: Testing Charging Time with a Battery
Next, ensure that your charger fills the battery adequately.
Prepare for Testing
- Choose a Depleted Battery: Make sure to test a DEWALT lithium battery that is completely depleted.
-
Charge the Battery: Insert the battery back into the charger.
-
Record the Time: Measure the total time takes to complete the charge cycle. For a healthy charger, the typical charge time is between 40 to 60 minutes.
-
Check the Indicator Lights: Use the indicator lights on the charger to confirm that it toggles from charging to a fully charged state.
If the battery takes longer than expected, it could point toward issues with the charger or the battery itself.
Step 4: Assessing the Charger’s Performance
Finally, determining the performance of the charger under normal operations can give you insight into its functionality:
Conduct a Charge Test
- Use a Charged Battery in Your Tool: Once the battery is charged, use it in a DEWALT power tool to see if it operates smoothly.
- Monitor Runtime: Take note of how long the battery lasts during operation. If the tool cuts out prematurely, it may suggest either a problem with the battery or the charger.
What to Do If Your Charger Fails the Tests
If your tests reveal that the charger is not functioning as expected, don’t panic. Several paths forward can help you remedy the situation.
Common Issues and Solutions
| Issue | Possible Solution |
|---|---|
| No Output Voltage | Reset the charger, check for damage, and try a different power outlet. |
| Long Charge Time | Inspect the battery for damage; if it is older than three years, consider replacing it. |
Warranty and Support
If your charger is still under warranty, contact DEWALT customer support for further assistance or replacement options. Providing proof of purchase will greatly enhance the process.

What is the proper way to charge a DEWALT Lithium 20V battery?
Charging a DEWALT Lithium 20V battery is straightforward but requires attention to detail for optimal performance. Start by checking the battery’s terminals to ensure they are clean and free of debris. Place the battery securely into the charger, making sure it sits properly to establish a connection. The charger will typically indicate the status through LED lights, showing whether it is charging or fully charged.
For best results, always use a DEWALT-compatible charger tailored for the 20V battery. Avoid charging the battery in extreme temperatures, as this can affect charging efficiency and longevity. If the battery is hot from previous use, allow it to cool down before charging to prevent damage.
How do I know when my battery is fully charged?
The DEWALT Lithium 20V battery charger is equipped with LED indicators that provide real-time feedback on the battery’s charge status. When you insert the battery, the charger will light up to show its current state; a flashing LED often indicates that the battery is charging. Once the battery is fully charged, a steady green LED light will typically illuminate.
Additionally, some chargers feature a battery capacity gauge that indicates how much charge is left before recharging is necessary. This feature can help you manage your workload and prevent unexpected downtime during projects.
Can I leave my DEWALT battery on the charger overnight?
While DEWALT chargers are designed with safety features to prevent overcharging, it is generally not recommended to leave your battery on the charger for extended periods, like overnight. Even though the charger will stop charging once the battery is full, continuous charging can generate heat, which might degrade the battery’s lifespan over time.
If you must leave your battery on the charger, try to ensure it is in a cool, well-ventilated area. It’s a better practice to monitor the charge and remove the battery shortly after it indicates a full charge to extend its longevity and maintain high performance.
What should I do if my DEWALT battery charger is not working?
If you notice that your DEWALT battery charger is not functioning, the first step is to check the power source. Ensure that the charger is plugged into a working outlet and that the power cord is intact and undamaged. Sometimes the problem might be as simple as a loose connection or a blown fuse in your electrical system.
If the charger still doesn’t work, try using it with a different battery to determine if the issue lies with the battery itself. If the charger is still unresponsive after these checks, it may need professional servicing or replacement, especially if it is under warranty. Contact DEWALT support for further troubleshooting guidance.
How can I extend the life of my DEWALT Lithium 20V battery?
To extend the lifespan of your DEWALT Lithium 20V battery, regular maintenance and usage practices are crucial. Avoid deep discharging your battery frequently; it’s best to recharge it when it drops to 30% capacity. This habit not only enhances battery life but also ensures that you will always have adequate power when needed.
Moreover, storing your battery properly is essential. Keep it in a cool, dry place, avoiding extreme temperatures. If you’re not going to use it for an extended period, store it at around 50% charge and check it periodically to ensure it remains in good condition. Following these guidelines can help maintain performance and prolong battery life.
What common issues should I be aware of when using the DEWALT Lithium 20V battery charger?
When using the DEWALT Lithium 20V battery charger, users should be mindful of potential issues such as incorrect connection or battery overheating. Always ensure that the battery is seated properly in the charger, as improper contact can prevent charging. If you notice the battery getting excessively hot during charging, it’s essential to disconnect it immediately and allow it to cool down.
Another common issue could be related to the LED indicators not functioning correctly. If you see erratic lighting patterns or the charger fails to respond, it may indicate a malfunction within the charger or the battery. If these issues persist after troubleshooting steps, contacting customer support for assistance would be prudent.
