DeWalt charger says “replace pack” (lithium battery) - EightFingers - 09-11-2018

Of course, that’s not what I want to see since these things aren’t cheap. So I look at the contacts and I get an idea maybe they could be cleaned up since they do look a little oxidized. I get a tiny flat file and give them a going over. 
Now the battery charges up just fine.
So FWIW, maybe this will save someone having to buy a new battery pack....

Sounds like a variation on the eraser trick I learned back when dinosaurs ruled.  While picking up a new video card at BB, the geek squadron guy mentioned some troubles with his.  I said "try the eraser trick first", only to get a puzzled look in response.  Next visit (for ink) he saw me and said "it worked", like he hadn't believed it would.  Guess not all components have gold plated contacts even now....
