I bought two new batteries two years ago, and neither one will take a charge and when they were new the power time was very short. I am a tinker and the batteries saw very little use. they will not take a charge at all. The original batteries lasted longer, but not the XRP 12V. They are expensive and short lived. DeWalt should recall these things. No more for me.
My advice is not to buy this compressor online. Buy from a local retailer. I went to purchase this compressor and the first one would not shut off but would run until the pressure relief activated. Took compressor back and asked to try the replacement before I left. Second one would not air up past 60 pounds. Hmmm? What's up Dewalt? Where is your quality? Prepared to take this third one back and ask for my money back if it acts up. Crazy.
