Lithium ion batteries are known for their efficiency and long lifespan. However, sometimes these batteries can encounter issues, such as not charging properly. In this article, we will discuss a simple and easy fix to reset your Dewalt lithium ion battery and get it charging again.

Understanding the Issue

If your lithium ion battery has been completely depleted or left unused for an extended period, it may need to be reset in order to start accepting a charge. Similar to a golf cart battery that loses its charge, each individual cell in a lithium ion battery may need to be recharged separately. Resetting the battery will provide a small amount of energy that the charger can detect, allowing it to initiate the charging process.

The Resetting Process

To reset your Dewalt lithium ion battery, you will need a fully charged battery to use as a reference. Locate the charging ports on both batteries and identify the positive and negative terminals. You will need a few pieces of speaker wire or similar conductive material to transfer energy from the charged battery to the depleted one.

  1. Take a piece of wire and connect the positive terminal of the fully charged battery to the positive terminal of the depleted battery.
  2. Next, connect another piece of wire from the negative terminal of the fully charged battery to the negative terminal of the depleted battery.
  3. Exercise caution while handling electricity and ensure proper safety measures are in place to prevent any accidents.
  4. Hold the wires in place for a few seconds, allowing the power to transfer from the charged battery to the depleted one.
  5. Release the wires and disconnect them from both batteries.

Testing the Result

After successfully completing the resetting process, it’s time to check if the depleted battery is now recognized by the charger and is ready to receive a charge.

  1. Connect the reset battery to the charger and observe if it shows any signs of charging or acknowledgment.
  2. If the battery is recognized by the charger, it should start charging, indicating that the reset was successful.
  3. However, if you still encounter issues or no reading is displayed on the charger, it is possible that the battery is completely dead and may need to be replaced.

Comparing Lithium Ion Batteries to Golf Cart Batteries

It’s important to note that lithium ion batteries behave similarly to golf cart batteries when it comes to complete discharge. In electric golf carts, if all the batteries are completely discharged, the charger will not detect them until each individual battery is charged separately. This is why resetting the depleted lithium ion battery is necessary to initiate the charging process.

Conclusion

Resetting a Dewalt lithium ion battery can solve the issue of it not charging. By following the steps outlined in this article and providing a small amount of energy from a fully charged battery, you can reset and revive your depleted battery. However, if the issue persists, consider seeking professional assistance or replacing the battery.

Good luck with resetting your Dewalt lithium ion battery and getting it back to optimal charging performance!
