Style: 20V MAX 6 Ah
I bought this 2-pack of DEWALT 20V MAX XR 6Ah batteries because the price was too good to pass up, and I’m really glad I grabbed them. These high-capacity batteries last a long time, and they’ve made a noticeable difference with the tools I use most. Whether I’m running drills, saws, or impact drivers, the power feels consistent and strong all the way through the charge. One thing I appreciate is how much less often I have to stop and swap batteries now. For bigger jobs or long days on a construction site, that extra run time really pays off. They also charge up pretty quickly for their size, which is a nice bonus. The build quality is exactly what you’d expect from DEWALT — solid, reliable, and made to hold up to daily use. They click into tools securely and don’t loosen or wobble like cheaper batteries sometimes do. Overall, these batteries were a great value and perform even better than I expected. If you rely on DEWALT tools and want longer run time without constantly rotating packs, this 6Ah XR set is definitely worth it.

Big and heavy, but they lassssst!! Granted these are probably intended for things like Leaf blowers and Circular saws, but I use them on everything, including DeWalt's light stand. Lasts well over 4 hours on that (More probably, but I finished in that time!

I am writing this review in hopes of clearing up problems with new batteries not charging. I ordered the pair of dewalt 20v 6 amp batteries. upon receiving the batteries they had 1 bar filled on the power indicator. I put them into the charger I already had dcb 115. The lights on the charger indicate they are charged, even though the battery is still showing 1 bar filled. I had the items replaced, they sent a new pair of batteries out. The new batteries had the same problem. one battery in the new pack even had the light for temp activate. even thought they sat in the house for 2 days. I was about to return the batteries and somebody told my it was the charger. Even though they tell you its universal and any charger will work...they wont. Today I purchased the dewalt fast charger DCB118. and the batteries are taking a charge, finally. it only cost me another $95.00 Since they sent a second pair of batteries and all 4 are charging, I guess that makes up for needing to buy another charger. The sellers may want to add that to the description: THAT YOU NEED THE DCB118 FAST CHARGER FOR THESE TO WORK.

Style: 20V MAX 6 Ah
I purchased a pair of these 6AH's in January 23 and another pair in August. I always write the month and year of the purchase of the battery with a Sharpie so I can keep up with the age (I have about 10 batteries in varying AH). About 6 weeks ago, I noticed that one of the 6AH batteries bought in January would only charge to level 2 and would drop immediately when put on a tool. When time permitted, I tried to recharge several times on a Dewalt multi-charger and a single charger, but same result. I finally gave up on dealing with it because I don't have time to for it. My concern is how long will the others last; these aren't cheap. I will probably not buy anymore of these 6AH's until I can feel confident that the one battery was a fluke. UPDATE, 29 AUG 25: Of the two pairs I bought in 2023, only one still works. Allow me to point out, I don't use these batteries all day, everyday for work (I work from a computer all day), but do rotate use regularly as I renovate my shop/office and around the properties projects (they're endless between the chicken coop, large garden and beds, irrigation, the well...). Because of these failures, that I feel are premature considering my moderate use, and the weight, I will not buy these 6AH batteries for general use; I do have some devices that require 6AH, 8AH and 12AH batteries, so I will not be able to completely rid myself of big Dewalt batteries. However, for general use, I've decided to try the 5AH batteries: smaller size, weigh less, less cumbersome, cost less and true, runtime is slightly less. Hope this helps.
