You're right, it's amazing that this needs to be done. Both my 20v batteries stopped charging, no light on the charger. I contacted Dewalt and, to their credit, they were easy to deal with and sent me a new charger. When that didn't work, it was clear to me that it was the battery that was the problem, not the charger. I had even gone to Lowe's and bought another charger, that I was able to return when it didn't help. Thanks for the vid. The batteries are charging right now!

THIS WORKED FOR ME!! I didn't have a battery jump starter and read in the comments here someone tried a regular 9v battery...like the kind that goes in a smoke detector... So I also tried a 9v battery with the razer blades and my dcb203 battery is now charging! I threw away at least 4 relatively new batteries recently with the same issue.. I bet all of them could have been jump started like this. THANK YOU !!!

WOW!!! I can't believe that worked. I got 2 dewalt 20v (2ah) batteries from a store that was throwing them away. The customer brought them back because they were dead. I put them on my charger and got nothing. Then I found this video. I used some wire to connect them to one of my battries for about 3 seconds each and now they are charging just fine.I learn something new every day. Thank you 😁😁

I can’t tell you how much this helped me. I just purchased a DeWalt cordless screwdriver for $100 bucks. It came with two batteries, a charger and tool bag so obviously a deal only problem is, the batteries wouldn’t charge. I brought it home and attempted to charge them for three hours and nothing. I found this video and tried it with a battery from a drill I have that does work and presto... the batteries are both now charging. You are a genius. Thank you. I’ll let you know if I get a full charge and a general update.

Thank you for this video! You saved me a lot of headaches and troubleshooting. I bought a brand new battery and charger kit, used the battery a few times, and then when it came time to recharge the battery for the first time, I was getting no lights on my charger. I was a bit skeptical trying this out. I tried with a 9V battery as some folks said, but that didn't work for me - possibly the battery was just a bit low. I also tried with my portable booster, but that didn't work either for some reason. My final attempt was using booster cables with my car battery. I saw a couple of sparks as you mentioned in the video, brought the battery back in and put it into the charger, and it started charging! (Charger is currently flashing red, which indicates that it is charging). Great trick, thank you!

Great video showing what to do if you can’t jump start from another battery. My FLEXVOLT has a partial charge and works on tools, but when put in charger, light briefly comes on and then goes off. I’ve tried cleaning the terminals, but makes no difference. Even though the battery still has a charge, would a jump start result in a ‘reset’ which might allow it to charge?
