Gas mowers are loud, high-maintenance, and increasingly outdated. The latest best battery powered lawn mower models deliver equivalent cutting power with push-button starts, zero emissions, and dramatically lower noise levels. Battery and motor technology has improved so much in the last few years that cordless mowers now handle yards up to half an acre on a single charge. Here are the top picks across every budget and yard size.
Top Battery Mower Picks
- Best Overall: EGO Power+ LM2156SP — $650-750, 21-inch self-propelled, 56V 10Ah battery
- Best Value: Greenworks 40V 21-inch — $280-350, push mower, 40V 5Ah battery
- Best for Large Yards: EGO Power+ LM2167SP — $800-900, 21-inch self-propelled, dual battery port
- Best Budget: Ryobi 40V 20-inch — $250-300, push mower, 40V 6Ah battery
- Best Compact: Greenworks 24V 13-inch — $150-180, ideal for small patches under 2,000 sq ft
EGO Power+ LM2156SP
EGO dominates the battery mower market for good reason. The LM2156SP uses a brushless motor and 56V ARC Lithium battery that delivers up to 60 minutes of runtime — enough for most yards up to 1/3 acre in a single session. The 21-inch steel deck cuts the same swath as a standard gas mower.
Variable-speed self-propulsion takes the work out of hilly terrain and thick grass. The 6-position height adjustment ranges from 1.5 to 4 inches. Mulching, bagging, and side discharge are all included. At $650-750 with a battery and charger, the upfront cost is higher than gas, but you eliminate annual oil changes, spark plug replacements, fuel stabilizer, and trips to the gas station.
Greenworks 40V 21-inch
For yards under 1/4 acre, the Greenworks 40V delivers solid performance at a budget-friendly price. The 5Ah battery provides 35-45 minutes of mowing depending on grass height and thickness. The 21-inch steel deck with 7-position height adjustment handles standard suburban lawns without issue.
This is a push mower, so you supply the propulsion. On flat yards that is no problem. On slopes or thick grass, you will feel the extra effort compared to a self-propelled model. The battery and charger are included at the $280-350 price point, making this one of the best values in the cordless mower category.
Ryobi 40V 20-inch
Ryobi’s 40V platform is sold exclusively at Home Depot, and the batteries cross-compatible with over 75 Ryobi outdoor tools. If you already own Ryobi trimmers, blowers, or chainsaws, adding this mower to the ecosystem makes financial sense since you can share batteries across tools.
The 6Ah battery provides around 40-50 minutes of runtime. A slightly narrower 20-inch deck means a few extra passes compared to 21-inch models, but the difference is negligible on most lawns. Build quality is solid for the price, and replacement parts are readily available.
What to Consider When Choosing
Battery Voltage and Runtime
Higher voltage generally means more power. The 56V EGO platform is the most powerful consumer-grade battery system available. Ryobi and Greenworks 40V systems are adequate for standard mowing conditions. Runtime depends on battery amp-hours (Ah) — a 5Ah battery lasts roughly 35-45 minutes, while a 7.5-10Ah battery extends that to 50-65 minutes.
Self-Propelled vs. Push
Self-propelled mowers use the battery to drive the wheels, reducing physical effort but consuming more power. Expect 15-20% less runtime compared to push mode. If your yard is flat and under 5,000 sq ft, a push mower is fine. Hilly terrain or yards above 7,000 sq ft benefit significantly from self-propulsion.
Deck Material
Steel decks are heavier but more durable. Polymer (plastic) decks resist corrosion and weigh less but can crack if you hit a solid object at high speed. Most mid-range and above models use steel. Budget models often use polymer to cut weight and cost.
Battery Mower vs. Gas: Real Cost Comparison
A quality gas mower costs $300-500 upfront. Add $50-75 per year in fuel, oil, filters, and spark plugs, and the 10-year cost reaches $800-1,250. A battery powered lawn mower at $350-750 upfront has virtually zero annual maintenance costs. Battery replacement after 5-7 years runs $100-200. The 10-year cost lands at $450-950, making battery mowers cheaper to own long-term in most scenarios.
Noise Levels and Neighborhood Considerations
One of the most underrated advantages of a battery powered lawn mower is how quiet it runs. Most cordless models operate between 60-75 decibels, roughly the volume of a normal conversation, compared to 90-100 decibels for a typical gas mower. That difference matters if you mow early mornings, have sleeping children, or live in a neighborhood with noise ordinances. Several municipalities now restrict gas-powered lawn equipment during certain hours, and some HOAs have banned them entirely. A battery mower lets you cut the grass at 7 AM on a Saturday without drawing complaints from neighbors.
Maintenance Tips for Battery Mowers
- Sharpen the blade every 20-25 hours of mowing, roughly 2-3 times per season. A sharp blade cuts cleanly and reduces motor strain
- Store batteries at room temperature, not in a freezing garage or hot shed. Extreme temperatures degrade lithium-ion cells
- Clean the underside of the deck after each mow with a hose or putty knife. Grass buildup reduces airflow and cutting efficiency
- Charge the battery fully before long-term storage. Storing at 30-50% charge is ideal for lithium-ion longevity
- Keep the deck height at 3-3.5 inches for most grass types. Cutting too short stresses the lawn and forces the motor to work harder
