Battery not charging on my impact wrench, any ideas?

Hey all, my DeWalt 20V impact wrench just stopped charging. The battery is fine in my other tools, but the charger says it's dead. I've cleaned the contacts and tried a different outlet. Any thoughts?

Could be the charger itself. I've had chargers die on me before. But also check the tool's battery terminal – sometimes they get bent or dirty. Also, make sure the battery is fully seated. If that doesn't work, try a different battery if you have one. If it charges, then it's the battery. If not, it's likely the charger.

I've seen this a lot on job sites. The charging contacts on the tool can get gunked up with grease and dust. Try wiping the contacts on both the battery and the tool with a clean cloth and some electrical contact cleaner. Also, check the tool's battery slot for any debris or damage.

My two cents: sometimes the charger has a thermal cutoff. Let it cool down for a bit. Also, try a different battery if you have one. If the charger still says dead, it's likely the charger's circuit board. I've had one that needed a new fuse – check for a blown fuse if you're handy.

I'm new to this, but I had a similar issue with my drill. Turned out the charger had a bad connection internally. I just jiggled the cord and it worked. But you might want to look at the manual for reset procedures. Some chargers have a reset button.
