20V MAX POWERSTACK Compact Battery Starter Kit

The light on my battery do not turn off they stay on all the time is it Defective?

Are these batteries disposable and should die on the first discharge.

Tool is great but this battery has failed already. Will not accept a charge. Very disappointed

This battery charges quickly, but doesn’t last very long, especially when used with recip saw. Good for small 20-30 min projects.

Im in the remodeling business and have several dewalt 20v tools including some of the first generation brushless impacts. But the batteries that came with them wore out along time ago so i bought some 4ah and 5ah batteries and they work great until I got ahold of the new power stack batteries. Wow what an upgrade!!! I tested them head to head with my DCF787's 4ah batteries running 5inch GRK 1/4 screws and the power stack won every time. It drove the screws 40% faster. I was impressed by the power for such a small battery. More power less weigh its a no brainer in my book powerstack is the real deal.

This battery is awesome! Compact, lighter and more power. It would be foolish not to purchase. I bought it to pair with my DCF850B and let me tell you its the perfect combo for tight spaces. The fact that I can use them with all my 20v DeWalt products makes it even better. I will be purchasing more and I highly recommend them.

[This review was collected as part of a promotion.] The wait is over !! The 20V MAX DEWALT POWERSTACK is 50% more powerful, 25% more compact, and 15% lighter. This battery features an impact-resistant, rubber overmold base and utilizes revolutionary pouch cell battery technology to provide twice the lifetime !! Get into tight spaces without sacrificing performance, our most powerful, most compact, and lightest weight battery and is compatible with the 20V MAX tools and chargers I already own.

[This review was collected as part of a promotion.] This little battery really packs a punch! I received this battery right before Christmas, and used it on many different jobsites. It is incredibly small and lightweight, it almost feels like a toy compared to the DCB203. One day I used it for framing with my 20v impact (DCF887) to run 3" deck screws, and it lasted for over 4 hours of heavy use. I like running the small batteries for weight, and compared to the other 20v 2ah and 3ah batteries, this unit has such a small footprint! In many cases it's slightly smaller than the base of the tool. This is great for lighter weight on the tool bag, and the Powerstack delivered consistent power. It charges very quickly on the fast charger as well, so two of these batteries will keep your impact going all day long. The only drawback one might consider, is with an oscillating tool or a similar tool where you want the larger battery case to help it stand up. In those cases I like the 3ah with the 21700 cells. I later ran the Powerstack battery outside, cutting cement backer board in very cold weather. I was using my oscillating tool in a pinch, with a diamond grout blade. This was a heavy application and the battery delivered incredible power!! It cut almost 20 linear feet before needing a charge, which is incredibly impressive for its size and the extreme cold. I try not to run batteries all the way down to make them last, so when it hits one bar, throw it on the charger. This battery was really comfortable on the 20v sander (DCW200) as well, with the reduced weight and improved balance, it was more ergonomic during extended use. Compared to the DCB230 battery I usually run on the sander, the Powerstack battery is about half the size and less than half the weight. I also couldn't resist trying it on bigger tools and it really impressed me. It cut plywood no problem with the circ saw, and even runs the big hammer drill (DCD999) in a pinch. I am excited about this new technology, and can't wait to see it applied to the Flexvolt batteries to reduce their weight, or even a 20v 4ah Powerstack battery. I'll definitely be filling my Toughsystem battery box with a few more of these.

[This review was collected as part of a promotion.] The Dewalt Powerstack is amazing power source with the power torque and longevity for any project. This power supply is designed with size and weight at the fore front. I have 2 other battery packs the 2AH and the 4AH. I tend to lean heavily on the the 2AH battery around the house for project. It was quickly substituted for the new Powerstack. I was able to disassemble a computer desk and reassemble the desk with out any issues. I then put the pack to the test installing a tv wall mount. I was able to drive the lag screws into the studs with easy. Both of these projects were done the same day and did not lose a single light on the battery, I will be putting this battery through the ringer with a framing job in the basement and a green house build in the spring. This is just another homerun for Dewalt!

[This review was collected as part of a promotion.] After I received the kit I immediately noticed the size and weight difference. The battery is 1/2" shorter and narrower than my DCB203 and definitely lighter. As I started testing in several tools I found it to be very comfortably balanced in the smaller, lighter tools. It provided good balance and no bulk in my Flashlight, impact driver or oscillating tool. When I tested the feel in my DCD998 Hammer Drill, initially I felt like I needed more weight in the battery in order to balance the tool to my comfort. While the battery is narrower and shorter, the length advantage is negated when the battery is placed in the tool because of the piece on the rear of every tool where the battery connects. It also tended to take a couple of tries to get the release lever down properly to remove the battery from a tool. I noticed the release lever protruded slightly from the battery unlike the DCB203 or DCB205. I didn't have any problems hitting the lever unintentionally but it did release differently than the old design where I thought it was stuck on the tools a couple of times. The performance in the flashlight and impact driver was as expected, I didn't test the runtime to exhaustion but the flashlight was on for 6+ hours and the battery was still at 2 bars (51-74%) and battery was cool. In the oscillating tool the Powerstack made a noticeable improvement when compared to the DCB203, 2aH. I don't ever use the DCB203 in the oscillating tool because it cuts so slowly where the Powerstack performed the similarly to my 5aH battery I usually use but with much better balance in the tool. I also tested the battery in my DCD998 while drilling some holes and I didn't notice a significant difference in power from the 5aH battery and the balance was better while using the tool than I initially expected. I also tested the batter on my Blower (DCBL722P1) and it again worked great. Again, I didn't test the tool to exhaustion of battery but it was light and comfortable any reduction in runtime wouldn't be a big issue since it is half the weight of the 5aH battery. I frequently just grab my DCB609 Flexvolt 9aH battery when using the blower because I never have to consider battery life but at 20% of the weight I'll use the Powerstack since it's so much lighter even if it means I need to grab a second battery at some point for long jobs. Overall, I was very impressed by the power of the Powerstack battery and the weight was really a difference maker when using the tools for a longer period of time. I'll definitely be looking at getting more of these batteries especially as the capacity increases. The performance and weight improvements significantly outweighed the small hassle with the release lever.
