    5.0 out of 5 stars Love this!

    Batteries were purchased along with the adapter so we could continue to use our old DeWalt cordless tools. What a lifesaver! So many tools we will not need to replace. It’s definitely worth the money. Everything works together seamlessly, and the battery life is great! In a world where everything seems to need to be upgraded or replaced every few years, this is perfect!

    Use dewalt impact daily for work. Battery pack holds charge, maybe have to charge 4 times a year. Charges quickly as well. Will not use any other battery pack. All dewalt products have been very reliable for me.

    5.0 out of 5 stars Compact and light best for Drills/Drivers
    Reviewed in the United States on July 17, 2024
    I have just about every DeWalt 20v tool, from basic drill to pole saws, hedge trimmers, etc. Very happy with all. I have a collection of 5AH and 6AH batteries, and ordered a pair of 2AH to use with my drill and 1/4" impact driver, due to light weight and compact size. I don't have experience with the "power stack" batteries or the 20/60 flex batteries. Received the 2AH today. 2/3 charge. Worked fine with my drill, and they are on the charger now.
    With regard to power/weight, the 2AH weight 365 grams (182g/AH), the 5AH weigh 635 grams (127 g/AH), and the 6ah (which is huge relative to the 5) weighs 975 g (162 grams/AH), so from that standpoint the 5AH is a clear winner in terms of power to weight.
    With regard to cost/AH, the 2AH pair cost $71 ($35.50 each, $17.75 per AH), the 6AH is currently selling on Amazon for $202.49 for a pair ($ 101.25 each, $20.25 per AH, and the 5AH is currently selling on Amazon for $129 for a pair ($64.50 each, $12.90 per AH). There is even a kit of 2 5AH, charger, and bag for $131.19 which is a great deal if you don't already have a charger(s).
    I knew this going in, and bought the 2 AH for compact size and less weight, but for power to weight and cost per AH, the 5AH seems to be the "sweet spot". You can do the math for other batteries (but I don't have weights): The "power stacks) are quite pricey. The 9AH 20/60 flex volt is $17,17 per AH, etc.
    In summary, the 2AH are light and compact, but not the best "value". Do your own comparisons based on your tools and needs. I don't know that I would trust the "knockoffs", fearing that I might set my house on fire....

    I previously wrote a bad review on a Dewalt 20V Max battery. Come to find out the battery was perfectly fine, and it was my charger that was no good. I bought a new charger and not only did this battery charge right up, but my old one did too. I eft a bad review prematurely. I now rate this transaction 5 STARS!

    "My battery doesn't hold a charge. I've been trying to get a project done and can only drive 6 screws in before it's dead. Worst money I ever spent, and I've been around a LONG time."

    Pretty nice fry cutter if you mount it to a board or to a wall, Suction cup feet are not the greatest but still a decent buy for the money.

    These batteries are very convenient because lightweight and they hold a great charge. Even though they may not last as long as the bigger ones do, at least your hand doesn’t get sore from holding the drill for hours at a time because of the batteries being lightweight.
