Batteries seem to be working good. I did have an issue that the LED charge indicators on one of them stayed on all the time. But called Dewalt and they replaced it under warranty. Seem to last longer than the older style 5ah dewalt batteries.

These are a nice product for my DeWalt tools. I am glad I ordered them. They were shipped quickly and packaged well. They arrived with a 30% charge but quickly accepted a charge to 100% in less than two hours. I used them initially on a 2-gallon portable DeWalt vaccuum and the battery was GREAT for the vacuum. It provide a lot of power. I really like them.

I feel like they hold a charge longer and make my mid sized 1/2 drive hit harder. Decent value in the two pack.

These new DeWalt power stack batteries are unbelievable! They have way more power, last way longer, and a smaller footprint. And also super price on these.

Used these in my hammer drill on my Ice auger. they lasted for over 30 holes drilled each in 27" of ice. Better than the old regular ones and almost 3 time better than after market.

More compact and a little lighter weight than other batteries. Long lasting and reliable

Me mandaron las baterías y solo una funciona la otra no el proceso de devolución es algo fastidioso les falta control de calidad

all good

These batteries are very durable and last a long time. They might seem a little heavy but you get used to it very quickly. Not only do last longer than most other brand’s versions they have a serious kick for when you need that extra bit of juice to get job done. I would 100% recommend these. One thing I will add is that take a very long time to charge if you don’t have a rapid charger.

Battery has loads of power at 5Ah. I really like its low profile, particularly when using it on the Dewalt power ratchet. I do have to note, the picture of the item shows these to be "XR" batteries but the ones sent to me do not say "XR" anywhere on them, so what you receive is not the same as what you see on the product page, they do look different. I'm not sure if the performance or quality will be impacted by this or not.

I like the way these ran when new they made my 6 1/2" trim saw run like a big dog. But from the first day, I noticed one battery seemed to run out of juice quicker than the other. I put a mark on it to double check, and when a battery was performing poorly, it was always the marked one.Over the next few weeks though, the other kept running worse. They cut out, often will never charge fully, etc. I have had them just over a month now, so Amazon will not take them back, and the original seller (Electronics Club) will not warranty them, they claim it is Amazon's responsibility.Awesome batteries if you don't get a bad pair, and if you get them from a legit seller.Side note, the 5ah Powerstack is pretty big, it doesn't fit a 1/4 impact with the belt clip on it. Works great for a trim saw. They don't last any longer than other 5ah batteries, but seem to make some tools run harder.

Simply put, this is a great battery. I only have two gripes with it, but it has performed well in every 20v application I have put it through. I tried to upload as many photos as I could to give you a better sense of the size including a comparison between the 1.7ah Powerstack and 5ah XR battery it replaces. Even threw in the beefy 15ah XR for good measure. These photos should also give you a better idea as to what it looks like on several tools.- - - - - - - - - - - - - - - - - - -Pros:- More runtime: Besides the FlexVolt batteries, I've noticed a good difference in runtime between the 5ah Powerstack and 5ah XR battery.- More consistent power: There is definitely more consistent power output in this battery (1.7ah included) than all the other XR batteries. This rivals the 12ah Flexvolt FlexVolt in terms of power consistency. That is impressive. It is most noticeable when I'm using tools like the cordless heat gun.- Rubber base: Just like the 1.7ah Powerstack, the 5ah has the grippy rubber base screwed on the bottom. I don't know why DeWALT refuses to do this on other batteries besides the Powerstack line, because it reduces the chance of marring whatever surface you place it on. Pretty nice.- Larger size: Some people are opposed to this, but I see it as a benefit. Because the base of the battery is wide, it makes whatever tool it's mounted too, harder to and less likely to get knocked over. That's a problem the 1.7ah has (in my experience). Last thing I want is to knock my drill over and damage flooring or fall off a ladder. Will the overall increase in size restrict where I can fit my tool? Yes, 100%. However, it is very rare I run into this problem, and if I ever do, I can just slap in the 1.7ah and I'm good to go. Both batteries compliment each other nicely and have their uses.- - - - - - - - - - - - - - - - - - -Cons:- Weight: This battery is HEFTY for a 5ah. Because of how densely the power cells are packed inside, this thing weighs a lot more than I was expecting. I think this in part to how much I got used to the weight of the 1.7ah and figured the 5ah wouldn't be too off. But it is easily 3x heavier than the 1.7ah and 1.5x heavier than the 5ah XR.- Cost: Obviously, this was going to come up. As you can tell by the price (at least at the time of writing this review) these puppies cost some serious bookoo bucks. ~$210 - $220 for 1 and ~$320 - $350 for the 2-pack. That cost is insane for 5ah batteries and is more in the FlexVolt price range. As a comparison, I waited for Black Friday and got 2, 15ah FlexVolt batteries for $500 on ACME Tools. Pretty crazy these can cost almost as much as a 15ah if you're patient. For myself and my business, I can afford it and the time saved due to the power output is worth the longterm cost, so this purchase made sense to me. Time is money. But the group of people this applies to may be a little niche and not worth the cost, especially since you can easily get 2, 5ah XR batteries for $150. At the end of the day, to each their own, what makes sense to you, may not make sense to others.- - - - - - - - - - - - - - - - - - -Would I recommend this battery? To very few people. Is it a great battery? Absolutely.
