    • Hate the Price… But Buy the Genuine DEWALT
Style: 20V MAX XR POWERPACK
DEWALT 20V MAX XR POWERPACK 4Ah I hate paying the price for genuine DEWALT batteries, but I’ve tried the cheaper import knockoffs and, for me, they just don’t compare. This 4Ah POWERPACK has become a great everyday battery. It’s compact enough that it doesn’t make the tool unnecessarily heavy, but still delivers plenty of power and useful runtime. The genuine DEWALT batteries have consistently been better for me when it comes to charging, power delivery, runtime, and longevity. Every time I need another battery, I’m tempted by the cheaper alternatives. 😂 Then I remember my experience and buy the DEWALT. Expensive? Yep. Worth it? Unfortunately for my wallet, absolutely. Five stars. ... show more

    • They are authentic.......
Style: 20V MAX XR POWERPACK
........I was skeptical too. Upon receiving I went straight to the Dewalt website to register for warranty purposes. After setting up an account and filling in the required information, they are indeed genuine batteries. I believe the warranty claimed 3 years of coverage. I guess time will tell. They did not come in any sort of box, they came wrapped in plastic. I thought I was scammed at first. The price was right. One thing I didn't like...after I hit the Buy Now button I noticed the seller has a restocking fee of up to 50% of the price on returns. Hopefully the will be alright. I'll update after I've used them for a few days. ... show more
