It was listed on Walmart’s site, but sold and shipped by another party. NYY I think was the seller. I left a review about contacting the seller and not hearing back, thinking I could update the review later. I checked, and I could not edit it, as I wanted to change it to them selling counterfeit batteries. I did give them one star.

Yes, the Dewalt batteries have a grey lettering/code. The yellow plastic also looks like a typical Dewalt battery.

What I'm trying to figure out is, how did the counterfeiters figure out how to use good serial numbers?? I'm questioning my stacked lithium batteries now. I figured since I was able to register, they were legit. I'm relatively convinced the batteries you had are fakes but somehow they were registered and obviously you got to legit batteries as replacement.

I don’t think the counterfeiters had good serial numbers, but it looks like Dewalt honored the warranty.

The writing in gray is an authentic DeWalt batteries and the serial number starts with an N but it’s much longer. The black writing is counterfeit and the serial number starts with a N but is much shorter. If I’m reading the numbers, right?

DeWalt replaced fake batteries with genuine OEM batteries?

Yes. And that surprise me.

I took apart the battery and it didn’t really tell me anything. I doubt DeWalt stamps the inside of their battery with DeWalt.

It’s easy enough, that I could take a part of a real battery to compare I suppose
