Excellent performance
The 8ah power pack works very well for my 6-1/2” XR circular saw as well as my 5” angle grinder. Lots of power and plenty of runtime. Highly recommend for high demand tools in the DeWalt 20v system

Solid purchase
OEM Dewalt batteries can't be beat, especially the Powerpack and Powerstack series. I was a little apprehensive about making the order because there are so many counterfeits out there, but this is an OEM battery, and the 8 Amp Hour batteries are great for a full day of runtime on my Dewalt circular saw, and I usually get 6-7 hours on the high setting on my Dewalt job site fan. The package arrived earlier than promised and that's another plus - a solid buy.

8Ah in a 6Ah pack size... HMMM...
I was expecting this to be closer to the 4Ah pack size, but it's not much smaller than the 6Ah. Also this is over kill for what I'm currently using this for, a drill. These are clearly made for their yard tools, or I think they have 20v (x2) table saws and miter saws, that these are definitely PERFECT for. As for the 50% increase in power, that's a bit of a lie. What it really is, is that it gives you FULL POWER from the start, something about those 18650 based batteries needs a little warm up before you can get the full power out of your tools, like 4Ah or more, the 2Ah is not enough, I think it's because the current requirement is high on most DeWalt tools and their RPM ratings are rated for 4Ah or more packs. Where as, even if you got the 2Ah PowerStack, you're getting that whole current power up front. I think it's because they can include a bigger buck converter... I saw a whole Youtube video explaining it. So, this is a great battery and also was literally 60 USD cheaper than Lowe's wanted. I think the two pack on here is literally nearly half the price of Lowe's two pack. They seem legit, been running my drill non-stop, for over 4hrs and haven't lost a pip in the meter, and it's an impact driver. Only negative, as I said, thought this would be smaller, it's still a sizeable battery.

DeWalt batteries are just awesome
I did not ***need*** this battery, but am I going to say "no" to 8 Ah of XR power goodness? I love DeWalt batteries in general -- I have several, some of which are probably at least 10 years old, and in my experience they are basically unkillable. I got this battery primarily for powering the cordless circular saw I (finally) got -- a saw will drain a 2 or 4 Ah battery pretty quickly, with any kind of heavier use. The one "con" so far is that the battery is a Reel Big Boi, for sure -- significantly larger than a standard 5 Ah battery, for example. You probably don't want this hanging off your drill, driver, or palm sander, unless absolutely necessary. But that's fine as I have the "normal" sized batteries for those applications.

Great DEWALT Quality:
A true Dewalt battery that runs and runs. Very happy with the product. Don't buy the useless "generic" batteries! Remember, you get what you pay for!
