🔧 DeWalt Battery Compatibility – What Fits What?
Most modern DeWalt cordless tools use the 18V XR / 20V MAX slide battery platform. This means batteries are interchangeable across a wide range of tools including drills, impact drivers, circular saws, grinders, nailers, and lighting equipment.
If your tool uses a slide-fit battery (not older stem-style), it will typically work with compatible replacements such as:
- DCB180
- DCB181
- DCB182
- DCB183
- DCB184
- DCB185
- DCB200
- DCB203
- DCB204
- DCB205
This shared platform allows multiple tools compatible with DeWalt batteries to run from a single battery system, making it easier to switch between tools on the job.
Are DeWalt Batteries Interchangeable?
Yes — within the XR / 20V MAX platform, DeWalt batteries are generally interchangeable. A single battery can power a wide range of cordless tools, which is why many users search for what batteries fit DeWalt tools or what tools work with DeWalt batteries.
This interchangeability is one of the key advantages of the DeWalt battery system, allowing flexible use across drills, drivers, saws, grinders, and more.
