DeWalt Battery being inserted into a DeWalt tool

The DeWalt battery line is extensive. They offer a variety of batteries that fit each power tool series, along with several battery lines that fit multiple power tools. It can get confusing on which battery is compatible with what tool and whether DeWalt batteries are interchangeable.


Currently, DeWalt’s cordless power tools are on two primary voltage systems: 20 volts and 60 volts. These voltage platforms are made to keep things running on the jobsite while also keeping costs effective.

Are DeWalt Batteries Interchangeable?

In short, some DeWalt batteries are interchangeable, but it all depends on the series and voltage. Use this guide to help see which batteries are capable of being used in a variety of DeWalt cordless tools and which are not.


Below are the battery system platforms that are available for purchase.


DeWalt Battery Platforms

Here's a detailed look at how their batteries work across different platforms

20V MAX System

The DeWalt 20V MAX System cordless tools are compatible with 20V MAX Batteries, including both the standard 20V MAX and XR (eXtreme Runtime) versions. This system has more than ten batteries available to choose from, depending on the tools and the amp-hours (Ah) needed.


The 20V MAX system is designed for trades in the most demanding environments and is built to maximize power, runtime, and space on the jobsite. The XR batteries are an extension of the 20V MAX line and are ideal for long-use applications, particularly when you don’t want to swap batteries out in the middle of a project.

FlexVolt System

Now, the FlexVolt system is a bit more advanced when it comes to interchangeability. Launched in 2016, the FlexVolt Battery System is the first of its kind to change voltage automatically when you switch tools. This means that you can both increase power and runtime as it’s compatible with 20V MAX Tools, 60V MAX Tools, and 120V MAX Tools (though some tools use two batteries to achieve 120V).

PowerStack

DeWalt’s PowerStack battery system is built using advanced pouch battery cell technology.


According to Ufinebattery.com, pouch battery cells are constructed in an aluminum-coated plastic film for a soft battery-like design. It’s become more popular due to its flexibility and compactness.


As described on LaserAX.com, the battery’s pouch cells are layered with two layers being active material surrounded by three solid sheets, plus a liquid electrolyte. Inside the layers, two conductive tabs are designed to stick out and weld to the positive and negative connectors inside, which allows the ions to travel easily between the cathode and anode through the electrolyte liquid when you charge or use the battery.


Overall, PowerStack batteries are compatible with all 20V MAX tools and chargers and provide up to 50% more power for an extra boost in power and performance, meaning that it has twice the lifespan of traditional DeWalt DCB205 5Ah cylindrical batteries

12V MAX System

If you’re in need of a smaller, lighter tool system that’s better suited for tight spaces or jobs that aren’t as heavy-duty, the DeWalt 12V MAX System could be a match for your toolkit. This battery system works only with other 12V MAX tools and chargers. The compactness of these batteries allows you to work one-handed and reduces the fatigue that comes with heavier tools and batteries.


So, while DeWalt batteries are interchangeable within their specific systems, it's important to match the right battery with the right tool. Adapters are available for bridging between some systems, making it easier to transition without replacing all your tools at once.

DeWalt Battery Sizes

Various DeWalt battery sizes on the ground

20V MAX and PowerStack Batteries

The 20V MAX DeWalt batteries come in three different sizes and offer up to 12Ah and as low as 1.2Ah. Ranging from lightweight to maximum choose the 20V MAX battery best compatible with your tool depending on the size and amp-hours. These batteries also feature the most powerful yet lightweight battery around, the PowerStack.


  • Standard 20V MAX Batteries (1.3Ah—2.0Ah): These are lightweight and compact, which makes them easy to use for extended periods without causing fatigue. They are cost-effective and ideal for less demanding tasks, with the added advantage of faster recharging due to their smaller capacity.

  • XR 20V MAX Batteries (3.0Ah - 5.0Ah) offer extended runtime and higher capacity, making them suitable for longer use without frequent recharges. They provide more power for demanding applications and are built to withstand heavy-duty use, making them a reliable choice for tougher jobs.

  • High-capacity XR 20V MAX Batteries (6.0Ah - 12.0Ah) are designed for maximum runtime and power. These batteries are ideal for all-day projects or jobs where recharging is impractical. They are versatile enough to power high-demand tools and applications, reducing downtime due to fewer battery changes.

Confused about what DeWalt XR batteries are? Don’t worry; let’s break it down. The XR stands for eXtreme Runtime or Extended runtime, and they’re exactly like the standard 20V battery, except they’re able to work longer in a more compact size. For a more detailed explanation of the DeWalt 20V XR line, check out this blog here.

FlexVolt Batteries

FlexVolt 20V/60V batteries come in a range of Amp-hours as well (6.0Ah, 9.0Ah, 12.0Ah, 15.0Ah). These batteries are unique because they will automatically switch between 20V and 60V, depending on the tool used.

12V MAX Batteries

FlexVolt 20V/60V batteries come in a range of Amp-hours as well (6.0Ah, 9.0Ah, 12.0Ah, 15.0Ah). These batteries are unique because they will automatically switch between 20V and 60V, depending on the tool used.

18V Batteries

Though DeWalt discontinued this battery system in 2021, they ran stock until March 2022. The DeWalt DC9096S 18V XRP Battery Pack is still in limited supply here at AuthorizedToolOutlet. If you’re looking for an improvement upon the 18V battery, HPAC Magazine has said that “the company (DeWalt) has also recommended users to make the switch to its 20V Max.” DeWalt also offers the option to trade in and recycle your 18V batteries through Call2recycle.


If you still have 18V batteries and want to use them, there is a  battery adapter  you can use to make them compatible with 20V MAX tools.

DeWalt Battery Compatibility

DeWalt batteries do offer backward compatibility with the same voltage range, like 20V MAX batteries, which are compatible with older 20V MAX tools or adapters that allow you to use 18V tools with 20V batteries. However, there are limitations when it comes to mixing battery types and voltages.


Factors such as battery size, voltage, and connector type can all impact compatibility. Check out the DeWalt Battery Compatibility chart below to help you get a better understanding of which tools go with what battery and what ones you can mix or match.

DeWalt Batteries Frequently Asked Questions

How to Determine What DeWalt Battery You Need?

With so many batteries available, it can be confusing to figure out which one you need for your tool. The last thing you want is to buy a battery that doesn't fit. Since the different power platforms look similar, make sure you choose the correct size before you finalize your order. DeWalt offers three main voltages for its cordless tools: 20 volts, 60 volts, and 120 volts. Each tool is labeled with the required battery size. 20-volt tools can use either 20V MAX or 60V MAX batteries, but 60-volt and 120-volt tools can only use 60V MAX batteries.

Are DeWalt batteries covered under warranty?

Yes, DeWalt batteries typically come with a 3-year limited warranty. This covers defects in materials and workmanship but does not cover normal wear and tear or misuse. Some smaller battery packs may only come with 2-year warranties, so it’s best to check and make sure when purchasing. 

What should I do if my DeWalt battery won’t charge?

  • Check the charger: Make sure it's plugged in and working.

  • Inspect the battery contacts: Ensure they’re clean and free of debris.

  • Try a different outlet: Sometimes, it’s as simple as a bad plug.

  • Contact DeWalt support: If all else fails, they can help determine if it’s the battery, charger, or something else.

  • Contact AuthroizedToolStore customer service here or DeWalt support here.

What happens if I try to use a 20-volt battery in a 60-volt tool?

It won’t work. The design of 60- and 120-volt tools includes plastic tabs that prevent a 20-volt battery from fitting. However, FLEXVOLT batteries are equipped with special ports, allowing them to be used in both 20-volt and 60-volt tools.
