Gas mowers still dominate American lawns, but the best electric mower models now match or exceed gas performance for yards up to 1/2 acre — and they do it without oil changes, spark plugs, or emissions. Battery technology has reached a tipping point where runtime, power, and cut quality finally justify the switch for most homeowners. Here are the top electric mowers worth buying right now.
Best Cordless Battery Mowers
EGO LM2156SP — Best Overall
EGO’s flagship 21-inch self-propelled mower sets the standard for cordless performance. The 56V ARC lithium battery platform delivers up to 60 minutes of runtime with two 5.0Ah batteries included. Peak power rivals 190cc gas engines, and the brushless motor runs at an impressively low 64 dB — quiet enough to mow early morning without waking neighbors.
The 7-position cutting height (1.5-4 inches), 3-in-1 capability (mulch, bag, side discharge), and LED headlights for evening mowing make this a complete package. Priced at $550-$650 with batteries and charger.
Pros: power comparable to gas, excellent runtime, quiet, rapid battery charging (60 minutes). Cons: two batteries add weight (70 pounds total), premium price.
Ryobi RY401150US — Best Mid-Range
Ryobi’s 40V brushless 21-inch mower delivers reliable performance at a more accessible price point. The included 6.0Ah battery provides 45-55 minutes of runtime on a single charge. Self-propelled rear-wheel drive, 7-position height adjustment, and 3-in-1 clipping management. Available exclusively at Home Depot for $380-$430 with battery.
Pros: strong value, compatible with Ryobi’s extensive 40V tool ecosystem, 5-year warranty. Cons: slightly less power than EGO in very thick grass, single battery setup means swapping mid-mow on larger lawns.
Greenworks 80V 21-Inch — Best for Large Yards
The 80V platform from Greenworks pushes battery power closer to commercial-grade territory. The higher voltage provides more torque for tall, thick grass and larger yards up to 3/4 acre. Runtime hits 60-70 minutes with the included 4.0Ah battery. Steel deck, 7-position height, self-propelled. Priced at $450-$530 with battery and charger.
Pros: excellent power for an electric mower, large-yard capability, steel deck durability. Cons: 80V batteries are heavier and more expensive to replace ($180-$250).
Best Corded Electric Mowers
Sun Joe MJ401E — Best Budget
At $100-$130, the Sun Joe MJ401E is the most affordable quality electric mower available. The 14-inch cutting width and 12-amp motor handle lawns up to 1/4 acre with ease. Lightweight at just 29 pounds, it is ideal for small suburban lots, elderly homeowners, or anyone who wants dead-simple maintenance (essentially none).
Pros: extremely affordable, lightweight, instant start, zero maintenance. Cons: 14-inch cut is narrow (expect more passes), 100-foot cord needed for most yards, push-only (not self-propelled).
Black+Decker BEMW472BH — Best Corded Full-Size
This 15-inch, 10-amp corded mower splits the difference between compact and full-size. The 6-position height adjustment and rear bag provide clean cuts at a price that is hard to argue with: $130-$170. A comfort-grip handle and relatively light 45-pound weight make it easy to maneuver.
Pros: affordable, reliable motor, good cut quality for the price. Cons: corded operation limits range, 15-inch deck is still narrow for larger lawns.
Electric vs. Gas Mowers: Real-World Comparison
The debate is narrower than it used to be. Here is how electric actually compares where it matters.
- Power: Top-tier battery mowers (EGO, Greenworks 80V) match 160-190cc gas engines. They struggle against 200cc+ engines in very thick, wet grass
- Runtime: 45-70 minutes per charge for quality battery mowers. Adequate for lawns up to 1/2 acre; pushing it for 3/4 acre without a spare battery
- Annual maintenance cost: Electric: $0-$20 (blade sharpening). Gas: $50-$100 (oil, filter, spark plug, fuel stabilizer)
- Noise: Electric mowers run 60-70 dB. Gas mowers run 85-95 dB. That is a massive difference — electric is conversation-level; gas requires hearing protection
- Lifespan: Brushless electric motors last 10+ years. Gas engines last 8-12 years with maintenance. Battery replacement ($150-$300) at year 4-6 is the hidden cost of electric ownership
What to Look for When Buying
Choosing the best electric mower for your situation comes down to a few critical factors.
Yard size matters most. Under 1/4 acre: any corded or basic battery mower works. Between 1/4 and 1/2 acre: invest in a quality cordless with at least a 5.0Ah battery. Over 1/2 acre: buy two batteries or consider a high-voltage platform like Greenworks 80V.
Self-propelled vs. push. If your yard has any slope, self-propelled is worth the upcharge ($100-$150 more). On flat ground, push mowers save battery life because the motor is only powering the blade.
Deck material. Steel decks are more durable and provide better cut quality. Polymer/plastic decks are lighter and will not rust but can crack from impacts. For long-term ownership, steel wins.
Battery compatibility. If you already own cordless tools, buy an electric mower that shares the same battery platform. EGO (56V), Ryobi (40V), DeWalt (20V/60V), and Greenworks (80V) all have extensive tool ecosystems.
Battery Care and Longevity
Lithium-ion batteries degrade fastest when stored fully charged or fully depleted for extended periods. After mowing, charge the battery to approximately 50% for storage. Keep batteries above 32°F in winter — a climate-controlled garage or basement is ideal. Avoid leaving batteries on the charger after reaching full charge, as continuous trickle charging shortens lifespan.
Most quality mower batteries deliver 500-800 charge cycles before capacity drops below 80%. At one charge per week during a 30-week mowing season, that translates to roughly 4-6 years of usable life — about the same interval as a gas engine needing its first major service.
