Dewalt 20 Volt Battery Won't Charge - FIX

If your Dewalt 20V battery won't charge, don't give up just yet. A common problem with these batteries is that they can lose their ability to hold a charge over time. This could be due to a variety of reasons including battery age or wear and tear.

I recently experienced this issue myself with my DeWalt 20V batteries. I had two packs that drained all the way down and couldn't get them to charge no matter what I tried. I even cleaned the contacts thinking that might be the problem, but nothing changed.

After some research, I found a fix that worked for me and may work for you too. The process involves connecting a charged new battery to your old, dead one. Here's how it works:

First, connect one wire from the B- terminal of a charged new battery to the old battery that doesn't charge anymore. Make sure to strip the ends of the wire to ensure a good connection.

Next, give it about 10-15 seconds and then remove the wires.

Finally, place the old battery onto the charger and see if it will now charge.

I tried this fix last night and it worked for me. My old batteries are now charging again, and I'm able to use them without any issues. I'm not sure how permanent the fix would be, as I haven't used the revived batteries for any length of time yet. However, you should notice that the old battery will charge again whereas before it wouldn't.

If you're experiencing issues with your DeWalt 20V battery not charging, there are a few common reasons why this might be happening. One reason is battery age - like any rechargeable battery, the DeWalt 20V battery has a limited lifespan and may eventually lose its ability to hold a charge.

Another reason could be that the battery contacts are dirty or corroded, which can prevent the battery from charging properly. In my case, I made sure the contacts were clean, but it didn't solve the problem.

If you're not sure what's causing your DeWalt 20V battery to not charge, you may want to try cleaning the contacts and seeing if that solves the issue. If not, this fix might be worth a shot.

I hope this helps someone else who is experiencing this issue with their DeWalt 20V batteries. And as an added bonus, I've saved myself from having to throw out potentially usable batteries - a win-win!
