For NiCad Batteries:

  1. Charge the battery fully, then let it sit for a couple of hours.
  2. Use your multimeter to check the voltage. If the voltage is still low, repeat the charging process.
  3. Continue cycling the battery three to four times, ensuring complete discharge and recharge each time.

For Li-ion Batteries:

  1. Charge the battery until fully charged.
  2. Use it until it is completely drained.
  3. Recharge and repeat this process several times.

Assessing Your Reconditioned Battery

Once you’ve gone through the charging and discharging cycles, it’s time to test the battery’s performance.

Testing the Voltage Again

Using the multimeter, measure the voltage again to see if there is an improvement. A successful reconditioning should show a significant increase in voltage, indicating the battery can hold a charge.

Conduct a Performance Test

Put the battery back into your DeWalt tool and use it for a task that it can handle. If it powers through the activity without lagging or cutting out, congratulations! Your battery has been successfully reconditioned.

When to Replace Your DeWalt Battery

There may come a time when reconditioning is not enough, especially if the battery is old or significantly damaged. Here are some indications that it might be time for a replacement:

  • Batteries that leak or swell are not safe to use and should be disposed of properly.
  • Even after multiple cycles, the battery fails to reach a satisfactory charge level.

In such cases, consider purchasing a new battery, preferably from authorized retailers to ensure quality and compatibility with your tools.

Conclusion
