I have 3 sets of the DeWalt 18v replacements from Amazon. They are only ok, wearing out earlier and not lasting as long as the originals. They sometimes throw a hot battery code when charging, something the DeWalt never did. By the looks of the sticker they all come from the same factory in China. I’m not sure they are a good value, but they get you back to using your tools for 1/4 the cost of the factory battery.
