DeWalt PowerStack Battery on Drill

Navigating the DeWalt battery systems can be complex. With so many options available, it can be challenging to determine which is right for you and your tool setup. The DeWalt PowerStack batteries are game-changers for cordless power tools, but understanding what they are and why they are so efficient is a topic of question.


If you’ve found yourself pulling your hair out over DeWalt’s PowerStack battery questions, we understand, and we’ve got your back, answering all your questions here.


Battery performance is crucial in today's fast-paced work environments. Whether on a construction site or tackling a home improvement project, the right battery can significantly impact productivity. Compared to traditional batteries, a lithium-ion battery is designed to deliver more power, extended life, and improved efficiency.


Let’s explore how DeWalt’s PowerStack batteries meet these demands. 

What Are DeWalt PowerStack Batteries?

DeWalt Powerstack Battery Infographic

DeWalt PowerStack batteries utilize advanced lithium-ion pouch cells instead of traditional cylindrical cells, which, in short, means that they’re more compact and lightweight.


Although PowerStack batteries are lighter and smaller than other batteries, they deliver more power to your tools while also offering a longer lifespan (when well-maintained). These batteries are engineered to provide professionals with consistent power throughout the job while also offering faster charging times to improve productivity.

How DeWalt PowerStack Technology Works

Lithium-ion pouch cell PowerStack battery technology is different from traditional cylindrical cells, which are often the most popularly used for power tools. This new technology allows you to store more in your toolbox with a 25% smaller battery and easily reach tough spots you couldn’t fit your power tool in before. 

In an interview done by Construction & Demolitions Recycling , Sean Fitzgibbons, director of product development for Black and Decker, said that “although cylindrical batteries were not made for high-power applications, the economies of scale that were made possible by their use in electric vehicles made them affordable for other applications. However, when a higher current is run through those types of cells, they tend to heat up. Once they reach a certain temperature, they must shut down the battery.

In comparison with traditional Lithium-ion batteries, these are slimmer without the bulk, and they’re more efficient in terms of energy density. Thermal management is also better regulated with these batteries and it also means that the pouch cells run cooler during use, which creates less heat resistance and fewer hot pack shutdowns. 

Key Features:

  • Compact Size: PowerStack batteries are smaller, making your tools easier to handle, especially in tight spaces.

  • Lighter Weight: The reduced weight of the battery helps decrease user fatigue, making jobs that run on longer more manageable.

  • Increased Power Output: These batteries deliver more power, allowing your tools to perform easily on demanding jobsites. 

4 Key Benefits of DeWalt PowerStack Batteries

DeWalt PowerStack Batteries, the most powerful battery in its class, offers four key benefits to help improve jobsite performance and increase user satisfaction. These improved benefits change the way we use, see, and think about power by providing better assistance with common challenges faced every day by professionals.

From an interview on PR Newswire , Jaime Ramirez, Executive Vice President & President of Global Tools & Storage for Stanley Black & Decker said, “Since its debut, our customers in the concrete and construction industries continue to applaud DEWALT's trailblazing advancement in battery technology that has the power to significantly impact the jobsite of the future," Ramirez also emphasized that "The DEWALT POWERSTACK 20V MAX Compact Battery is one example of DEWALT's relentless pursuit to pioneer innovative construction solutions."

  1. 50% More Power: The PowerStack battery delivers 50% more power compared to traditional cylindrical batteries. This increased power means that even the toughest tasks can be handled with ease, whether it's driving large screws into hardwood or drilling through concrete.

  2. Enhanced Efficiency: With 50% more work per charge, this battery optimizes tool productivity, allowing you to get more done without frequent recharges. This is particularly beneficial on large projects where efficiency is key.

  3. Double the Lifespan: The PowerStack battery offers twice the lifespan of traditional cylindrical batteries, meaning that you get a better long-term value for your tools. This also means that you’ll have fewer replacements and less downtime away from the job, ultimately saving you money in the long run.

  4. Durability : The non-marring over-molded rubber base not only protects the battery but also the surfaces it comes into contact with. This feature is crucial in maintaining the integrity of both the battery and the work environment.

Designed for Professionals in Mind

Built for the pros, the Powerstack 20V MAX 5Ah Battery amps up your time. Whether you’re drilling, sawing, grinding, or more, These batteries supercharge your tools, delivering a power punch that keeps you charging ahead with no slowdown.


For example, let's say you're a carpenter working on a big project, and you’ll be making a lot of straight cuts with your circular saw. The last thing you want is your battery dying halfway through and having to start over. With the DeWalt PowerStack, you're getting consistent power and longer run time, so you can keep cutting without constantly swapping out batteries, because we all know how inconvenient it is to have to restart the process when you’re in the zone.

PowerStack Features:

  • Compatibility : PowerStack batteries connect seamlessly with all DeWalt 20V MAX tools and chargers. If you already have 20V MAX power tools readily available, you don't need to purchase additional tools or chargers. This makes it easy to upgrade your existing DeWalt setup.

  • User-Friendly: Worried about how you can tell if it’s running out of battery? Luckily, DeWalt implemented a 3-LED fuel gauge into the battery that displays the battery’s state of charge, helping you manage your work and avoid unexpected work stoppages.

20V MAX and PowerStack Batteries

The 20V MAX DeWalt batteries come in three sizes, ranging from 1.2Ah to 12Ah, and are compatible with various tools based on their size and amp hours. The lineup includes:

  • Standard 20V MAX Batteries (1.3Ah—2.0Ah) : Lightweight and compact, ideal for less demanding tasks and extended use without fatigue. They recharge quickly due to their smaller capacity.

  • XR 20V MAX Batteries (3.0Ah—5.0Ah) : Offer extended runtime and higher capacity, making them suitable for demanding applications and heavy-duty use.

  • High-capacity XR 20V MAX Batteries (6.0Ah—12.0Ah) : Designed for maximum runtime and power, perfect for all-day projects and high-demand tools.

The PowerStack batteries are the most powerful and lightweight option available in this range.

Expanding the PowerStack Platform
