Can I use Milwaukee batteries in DeWALT tools?

No. DeWALT, Milwaukee, Ryobi, and other brands use proprietary battery connections. A Milwaukee M18 battery will not physically attach to a DeWALT 20V tool and vice versa. Each platform requires its own batteries and chargers. This is why platform choice matters before buying your first tool — switching platforms later means replacing all batteries.

Is DeWALT or Milwaukee better?

For professional tradespeople: Milwaukee M18 FUEL has a slight edge in professional-grade tool selection and FUEL brushless performance. For DIY homeowners and contractors who need wide availability and starter kits with batteries included: DeWALT 20V MAX is more commonly found in budget-friendly kits. Both are excellent platforms — the choice often comes down to which brand the people you work with use, since battery sharing is only possible within a platform.

Can I start with Ryobi and upgrade to DeWALT later?

Batteries do not transfer. Starting with Ryobi means your Ryobi battery investment stays with Ryobi tools. Upgrading to DeWALT means buying new batteries. The transition cost is real — factor it into the decision. Ryobi is the correct choice if budget is the priority; DeWALT or Milwaukee are correct if you expect to buy many tools over time.

DeWALT vs Milwaukee vs Ryobi: How to Choose a Battery Platform

Choosing a power tool battery platform is the most important decision before buying your first cordless tool. DeWALT 20V MAX, Milwaukee M18, and Ryobi ONE+ each serve different users — here is how to pick.

Battery platform choice is permanent in a way that individual tool choice is not. A wrong tool choice costs you one purchase. A wrong platform choice costs you every battery you have ever bought when you want to switch.

Make this decision once, deliberately, before buying your first cordless tool.

The Three Platforms Worth Choosing

DeWALT 20V MAX Best for: homeowners and professionals who want wide availability, starter kits with batteries, and compatibility with future FLEXVOLT 60V tools.

Strengths:

200+ compatible tools
Most starter kits include batteries and charger
Widely available at every hardware retailer
FLEXVOLT compatibility means 20V batteries work on 60V tools (at reduced capacity)

Limitations:

ATOMIC brushless tools are better than budget DeWALT but slightly behind Milwaukee FUEL at the premium tier

Milwaukee M18 Best for: professional tradespeople who want the widest range of specialty tools and best-in-class FUEL brushless performance.

Strengths:

275+ compatible tools with the most specialty options
M18 FUEL brushless tools are the performance benchmark
ONE-KEY smart battery tracking and tool management

Limitations:

Starter kits often sold tool-only (batteries purchased separately)
Premium pricing across the lineup

Ryobi ONE+ Best for: homeowners and DIYers who want the most tools for the least total cost.

Strengths:

300+ compatible tools — largest ecosystem by tool count
Lowest average price per tool
Available at Home Depot with easy access to batteries

Limitations:

Performance ceiling below DeWALT and Milwaukee at maximum load
Not used by professionals — tools aren't as durable for daily commercial use

Making the Decision

Ask yourself three questions:

Will I ever work alongside tradespeople whose tools I might need to borrow batteries from? If yes, find out what platform they use.
How many tools do I expect to own in 5 years? If more than 5-6 tools, the battery platform investment compounds — choose DeWALT or Milwaukee. If 2-3 tools, Ryobi's lower entry cost makes more sense.
What is my most demanding regular task? For heavy framing and demolition: Milwaukee M18 FUEL. For standard home repair and improvement: DeWALT 20V MAX. For occasional home projects: Ryobi ONE+.
