Universal Product Code (UPC check)

I can't say anything bad about this battery. When I want to use my pole saw, saw saw, or my lopper, I grab this battery. After endless cuts and going from tool to tool this battery still has indicates nearly a full charge. It also provides plenty of power for any task.

Powerful and long lasting

dewalt.com

I bought this product about 2 months ago.  Amazing power!!  I used this battery in my 20v Max XR skill saw and it lasted all afternoon, still showing full charge at the end of the day.  I was cutting 2x4's and 2x6's for blocking walls. **Note, this battery is heavy, best suited for Skill saw, or reciprocating saw, or SDS, etc.

Amazing power!

[This review was collected as part of a promotion.] I've been using the 20V MAX XR POWERPACK™ 8Ah Battery with my DEWALT tools, and I have to say, it's been a game-changer. Right off the bat, you notice the difference in power—this thing delivers 50% more juice than the older batteries I was using, which is perfect for tackling tougher jobs.

The extended runtime is a huge plus. I can work all day without needing to stop and recharge, which keeps me moving and gets the job done faster. And the fact that it's compatible with all my 20V MAX tools makes it even better—no need to lug around different batteries.

What really stands out is how reliable it is. The tabless cell technology means it's built to last, and I can tell it's going to hold up for the long haul. Overall, if you're thinking about upgrading your battery, this one is a no-brainer. It's powerful, long-lasting, and just makes everything easier.

Battery that packs a punch

[This review was collected as part of a promotion.] Thos battery is so much nicer than the old style . The fact they have turned the charge lights around is big for me . Also this thing takes for ever to run out of charge I have had it on my small blower and mostly my fan when I used to have t use my flex volt batteries to get the same run time ! Over all I'm very impressed with the power stacks the only down side I see is it's still kind of hard to get slid in and out of some tools . The release doesn't always disengage fully .

These will charge you up !

[This review was collected as part of a promotion.] This battery has the largest capacity in my DeWalt tool collection. Previously, I mostly used a 6AH battery for high-power devices like the vacuum cleaner, circular saw, trimmer, or blower, and I wasn't always able to finish a project on one battery or charge. This 8AH battery is the same size as the others but provides a longer running time for my tools. The rubber texture on the bottom makes it more comfortable for daily use by professionals. It's more stable and doesn't slide around inside the toolbox or on my van's shelf while I'm relocating.

Big capacity and pretty compact

[This review was collected as part of a promotion.] This battery packs a boatload of power I've purchased plenty of the six amp hour power stack batteries, and they work fantastic but this eight amp hour is top-notch. The features are Way better than the other model

The perfect battery with the most powerful drill..

[This review was collected as part of a promotion.] I've been using this pretty regularly for about a month. It had two bars of charge when I got it. I know you're supposed to fully charge before using but I went ahead and put it to use. I've been using it with my circular saw, ratchet, drill, and driver pretty rigorously and am just having to charge it about a month later.  Absolutely no drop in power. Full strength until it was completely exhausted.

Plenty of power!

[This review was collected as part of a promotion.] I thought my old batteries last on a given charge, but the XR has surpassed my expectations.  I use it with my impact and hammer drills interchangebly and the juice holds up.  I used it with my Dewalt bluetooth speaker and lasted all day long.

A powerpack to stay

[This review was collected as part of a promotion.] I'm a do-it-yourselfer. This 8ah battery is a game chnger when it comes to doing a big project because it allows me to work all day, without the need to change batteries. A great addition to my toolbox.

lasts all day, without a battery change

[This review was collected as part of a promotion.] The Dewalt 8 Ah 20V MAX* XR battery is a powerhouse addition to any professional or DIY toolkit. Designed to deliver extended run times without the need for constant recharging, this battery packs serious performance into a compact unit.

One of the standout features is its 8 Ah capacity, which provides more than double the run time of the standard 4 Ah battery. Whether you're using it in power-hungry tools like impact drivers, saws, or grinders, the battery delivers consistent power throughout your job. For those tackling long projects or working in demanding conditions, this extended capacity means less downtime and more productivity.

Durability is another strong point. Like other Dewalt products, the 8 Ah battery is rugged and built to withstand the harsh environments of construction sites. It features an advanced lithium-ion design, making it lightweight despite its high capacity. It also charges relatively fast, given its size, especially when paired with a fast charger.

However, this battery does come at a premium price point, and its larger size might add noticeable weight to smaller tools, which can be a concern for those needing more mobility or working in tight spaces. Despite this, the performance gains make it a worthy investment for serious users.

Overall, the Dewalt 8 Ah 20V MAX* XR battery is a solid choice for anyone needing extra run time, durability, and reliability in their power tools. It's perfect for pros and serious hobbyists alike who need to keep their work moving without constant interruptions for recharging.

8Ah Powerhouse MAX!

Individuals use to take great pride owning Dewalt products, but now, not so much. You use to build things that lasted, but it seems you've really lowered your standards especially when it comes to supporting DIY'ers & homeowners. We purchase your products knowing we're are spending a lot of money, hoping they will last a long time since we aren't using them everyday, hoping they will  live up to the OLD DEWALT STANDARDS & PROMISES!

DEWALT TOUGH, Highest Standards, built for the unbreakable, a name that means something, not anymore.

No longer a dewalt fan
