What Is the Best Battery-Powered Lawn Mower? [2025]

What Is the Best Battery-Powered Lawn Mower in 2025?

The best battery powered lawn mower for most homeowners is the EGO Power+ 21-inch Self-Propelled. It delivers gas-like cutting performance, 45–60 minutes of runtime on a single charge, and thoughtful features like variable-speed drive and LED headlights. If you’re in the Milwaukee M18 platform, the M18 FUEL 21-inch is a close second; budget buyers should look at the Ryobi 40V HP Whisper Series.

Gas mowers are dying, and the EGO Power+ 21-inch Self-Propelled is one of the reasons why. This battery-powered beast delivers power that rivals gas engines, runtime that handles most yards on a single charge, and zero maintenance headaches. It's the mower we'd buy for our own lawn.

Why the EGO Power+ Wins

After testing battery mowers from every major brand, the EGO Power+ kept standing out for its combination of cutting power, runtime, and smart features. It's not just a good battery mower—it's a great mower, period.

The 56V Arc Lithium battery system delivers consistent power from start to finish, and the self-propelled drive makes it effortless to push even on slopes. The LED headlights and weather-resistant construction are nice touches that show EGO thought about real-world use.

What Makes It Special

Gas-Like Power, Battery Convenience
The EGO cuts through thick, wet grass without bogging down. We tested it on overgrown sections that would challenge most battery mowers, and it powered through without hesitation.

Impressive Runtime
With the included 7.5Ah battery, you're looking at 45–60 minutes of runtime depending on grass height and thickness. That's enough for most suburban yards on a single charge.

Self-Propelled Drive That Actually Helps
The variable-speed self-propelled system makes mowing feel effortless. Adjust the speed to match your walking pace, and the mower does the work.

LED Headlights
Sounds gimmicky until you're finishing up at dusk and realize you can actually see what you're cutting. It's one of those features you don't know you need until you have it.

Runner-Up: Milwaukee M18 FUEL 21-inch

If you're already deep in the Milwaukee M18 ecosystem, the M18 FUEL 21-inch is a fantastic mower. It delivers similar cutting power to the EGO and uses the same batteries as your drills, saws, and other Milwaukee tools.

Why it's close: The Milwaukee is powerful, well-built, and integrates seamlessly with the M18 platform. But runtime is shorter (you'll likely need multiple batteries for larger yards), and the price is higher when you factor in battery costs.

Best for: Milwaukee tool owners who want to maximize their battery investment.

Best Budget Pick: Ryobi 40V HP Whisper Series

Need a solid battery mower without spending $600? The Ryobi 40V HP Whisper Series delivers surprisingly good performance for around $399 (kit). It's quieter than most competitors, cuts well, and the 21-inch deck handles typical suburban yards with ease.

Trade-offs: Less power than EGO or Milwaukee, shorter runtime, and no self-propelled option. But for smaller yards and budget-conscious buyers, it's a great value.

Best for: Homeowners with small-to-medium yards who want a reliable battery mower on a budget.

Who Should Buy What?

• EGO Power+ 21-inch → Best for most homeowners who want maximum power, runtime, and features.
• Milwaukee M18 FUEL 21-inch → Best for Milwaukee tool owners who want to leverage their existing battery platform.
• Ryobi 40V HP Whisper Series → Best for budget buyers with smaller yards who don't need self-propelled drive.

Final Thoughts

The EGO Power+ 21-inch Self-Propelled is the lawn mower that finally makes gas engines feel obsolete. It's powerful, convenient, and packed with features that make mowing less of a chore. Whether you're tackling a quarter-acre lot or a larger suburban yard, this mower gets it done with zero gas, zero oil changes, and zero pull-starts.

👉 Bottom line: For most homeowners, the EGO Power+ is the best lawn mower you can buy in 2025.
