Our Picks at a Glance
How To Choose The Best Electric Battery Lawn Mower
To pick a cordless mower that fits your yard, focus on three numbers: voltage (V), amp-hours (Ah), and cutting width. Voltage tells you the motor’s peak power, amp-hours tells you how long the battery lasts, and cutting width tells you how many passes you will make. Nail these three, and the rest is just comfort features.
Match the Deck to Your Lawn
A 21-inch deck covers far more ground per pass than a 15-inch deck, but it is heavier and harder to turn around flower beds. Small yards under a quarter-acre work fine with a 15 or 16-inch deck, while half-acre lots need a 20 or 21-inch deck to avoid an afternoon of pushing. Wider decks also mean the front wheels are farther apart, which changes how well you can trim along edges.
Battery Voltage and Runtime Are Different Things
Voltage is about cutting power—a 56V or 80V motor can chew through thick, damp grass that bogs down a 40V model. Amp-hours (Ah) is the fuel tank, so a 10.0Ah battery lasts far longer than a 4.0Ah one even at the same voltage. Check both numbers together, because a high-voltage mower with a tiny battery runs out of steam quickly.

In-Depth Reviews
1. EGO POWER+ 21″ Self-Propelled (LM2135SP)
Our pick — over 4.5★ from 650+ verified ratings; the strongest balance of quality and price.
The 21-inch self-propelled gas replacement that finishes the job without the fumes.
This is the mower people switch to when they want to retire their gas machine for good. It delivers up to 7.0 ft-lbs of cutting torque—the twisting force that lets it power through dense grass—and with the included 56V 7.5Ah battery plus the extra 5.0Ah unit, you get up to 60 minutes of runtime per charge. For a half-acre lot, buyers report that a second battery is worth having on hand, but even a single charge handles a third of an acre with ease.
What wins people over is the Touch Drive self-propel system: you engage it with the touch of your palm and adjust speed with a dial at your fingertips. Compared to the 9-inch mini mower below, this 21-inch deck covers more than twice the grass per pass, and its 8 cutting height positions let you dial in from 1 to 4 inches. The Select Cut multi-blade system ships with mulching, high-lift bagging, and extended runtime lower blades, so you customize the cut to the season.
Owners mention it is “Reliable all season; half-acre needs 2 batteries.” The mulching blade stays sharp through an entire season, and the quiet, instant start removes the biggest annoyances of gas ownership — no fuel, no smell, no oil changes. The main trade-off is that battery drains faster on tall or wet grass, and with self-propel engaged, so you may need to manage your mowing pace on tougher days.
The Crowd Favorites
- Performance is the most-praised trait — owners single it out constantly
- Battery life is a close second, with high praise for the 56V system
- Quiet operation and easy push-button start make it a joy to use
What to Know
- Battery drains faster on tall or wet grass
- Self-propel can slow down as the battery depletes
Reach for this if: you have a quarter-acre or larger and want a true gas replacement that mulches beautifully.
Consider a smaller deck if: your yard is under 2,000 square feet, where a lighter machine is easier to maneuver.
2. STEELITE 40V 17″ Brushless Mower
The lightweight 30-pound push mower that tucks into a corner of the garage.
If your “lawn” is more of a postage stamp, this 17-inch mower from STEELITE is the budget-friendly way to keep it tidy. It packs a 3,400 RPM brushless motor and runs up to 25 minutes per charge on its two 20V 4.0Ah batteries combined. You get a 6-position height adjustment that runs from 0.98″ to 2.95″, so you can go from a close cut in spring to a taller setting in summer heat.
The 2-in-1 design lets you switch between bagging grass into the 40L capacity bag or mulching it back into the lawn as natural nutrients. At only 30 lbs, the whole unit is light enough for anyone to push, and the foldable handle makes storage in a closet or shed genuinely simple. The kit includes the mower, two batteries, charger, and grass bag, so there’s nothing else to buy.
Owner feedback is split on the battery: some say it lasts a surprising ~30 minutes, while others report “Fully charged batteries only last 15-20 minutes.” That makes it a fine pick for tight spaces and quick touch-ups, but not for pushing across a large yard in one go. The flimsy bagger can detach mid-mow on some units, and the 3-hour charge time means you need patience between sessions.
Who it fits: small yards, apartment patios, and first-time cordless buyers who want a light, easy machine at a great price.
The honest limit: runtime is the recurring gripe, so treat it as a trimmer for modest lawns, not a workhorse for acreage.
3. RB 40V 9″ Mini Cordless Mower
The 11.5-pound trimmer that treats your lawn like a vacuum cleaner.
This is the mower for the smallest jobs, and it nails them. Weighing just 11.5 lbs without the battery, the RB 40V mini mower is nearly easy to push, with pivoting front wheels and one-hand steering that swivels into tight corners. Its 6,000 RPM brushless motor handles a 40V 2Ah battery and covers small lawns up to 540 sq. ft. on a single charge — which gives you about one hour of runtime.
You get 3 cutting heights from 1.2″ to 2″, which owners find ideal for keeping small, bumpy yards healthy. Unlike the 21-inch EGO above, this 9-inch deck is built for precision, not volume—think edging along fences, cleaning up around the patio, or keeping an RV lot neat. The upright storage design saves up to 70% of floor space, and the detachable aluminum handle means it fits anywhere.
Buyers compare using it to “using a vacuum cleaner” and praise how easily it swivels in tough spots. The safety system automatically stops the blade if the mower tilts beyond 20°–70°, which is reassuring on uneven ground. The trade-off? You must hold the trigger while mowing—there is no lock—and the wide wheelbase can prevent true edge-to-edge trimming on some curves.
What Owners Rave About
- Size is the top praise — perfect for tight spots and tiny yards
- Ease of use scores nearly as high, easy even for seniors
- Mowing performance holds up on bumpy, rocky terrain
Trade-offs to Expect
- Requires holding the trigger with no lock
- Wide wheelbase limits true edge trimming
Best for: anyone with a genuinely tiny yard, a patio, or a need for fast, easy cleanup in hard-to-reach areas.
Not for: anyone expecting to mow a standard suburban lawn in a few passes — bring a bigger deck for that.
4. SENIX 40V 15″ 2-in-1 Mower
The compact 15-incher that offers a battery gauge and an ECO mode to stretch your runtime.
When you want to know exactly how much battery you have left, the SENIX delivers with an on-board charge indicator that shows remaining power at a glance. Its 40V Max X2 system runs two 20V lithium-ion batteries, giving you up to 45 minutes of continuous operation after a full charge (about 135 minutes to recharge). The 15-inch cutting width and 32-pound weight make it a nimble choice for small to medium-sized yards.
A 6-position single lever adjusts cutting height from 1″ to 3″, and the folding handle simplifies storage in tight spaces. The innovative ECO Mode boost battery life, which matters when you are covering more ground than a patio. The included 11-gallon grass bag makes collection easy, and the 2-in-1 feature lets you switch between mulching and bagging.
Owner sentiment is strong on performance, with one buyer noting it handles a whole backyard with good power and no slowdowns, and another saying it outperforms a gas mower that cost significantly more. Battery life is where opinions diverge, though — while some report great range, others found it drains fast in thicker grass. It is a solid mid-range pick if you keep expectations set for a modest lawn.
The smart-buyer take: for small yards with regular mowing, this is a lightweight, well-featured option that outperforms its price tier on cut quality.
Where it stumbles: longer or overgrown grass drains the battery quicker, so budget your passes accordingly.
5. Wild Badger Power 40V 18″ Brushless Mower
The 18-inch, 37.5-pound balance of deck width and maneuverability for open lawns.
This Wild Badger mower aims directly at the small-to-medium lawn owner who wants fewer passes without wrestling a heavy machine. The 18-inch brushless deck reaches up to 3,400 RPM, and the included 40V 4.0Ah battery gives you up to 60 minutes of runtime depending on conditions. At 37.5 lbs, it strikes a balance between coverage and maneuverability, and the folding handle trims storage space.
You get five cutting height positions spanning 1.5″ to 3.5″, letting you adjust for seasonal growth or leave grass longer in warm, dry weather. The 3-in-1 system covers bagging, mulching, and rear discharge, and the included 11-gallon bag helps keep clippings collected for a clean finish. A 3-year limited warranty and 24-hour customer support back the purchase, which is a nice safety net.
Buyers praise the cut quality and how easily it pushes, with one owner handling a bigger yard on a solid 45-minute battery charge. The recurring concern, though, is the battery ecosystem: a few owners found the 40V battery hard to source as a replacement, and some noted the mower can turn off and need a restart if the grass is too thick. It is worth confirming battery availability before you commit, especially for larger yards that need multiple charges.
Why it earns a spot: a genuinely pleasant push mower that covers ground efficiently and cuts evenly on weekly maintenance.
Proceed with this in mind: research replacement battery availability first if you have a large yard, since a spare is the real safety net.
6. MZK 40V 16″ Brushless Push Mower
The crowd-favorite 16-incher that turns mowing into a family activity.
Owners of this MZK mower describe it as “very easy to push” and “super lightweight,” with more than one noting their kids volunteered to mow again — which tells you everything about how easy it is to operate. The brushless motor spins up to 3,400 RPM for strong cutting, and the 2-step safety start helps prevent accidental start-ups, which parents appreciate. The 16-inch cutting width and 40L removable rear grass bag handle the collection neatly.
The kit is generous: you get two 20V 4.0Ah batteries plus a dual-port charger, so you can hot-swap and keep mowing without waiting for a recharge. Five cutting height positions from 1.4″ to 3″ let you match the seasonal growth, and 2-in-1 mowing supports mulching or rear bagging. It is ideal for medium-to-large gardens where a single battery would be limiting.
Owners consistently praise the build quality and the two batteries for uninterrupted runtime. It’s a dependable machine that delivers a clean cut, easy push, and enough battery to finish the job. It skips gimmicks and focuses on a clean cut, easy push, and reliable battery life.
The verdict: a no-fuss, well-built mower that makes weekly maintenance feel like less of a chore.
Keep in mind: at 65 lbs, this is not the lightest option, so consider your own strength if you have steep slopes.
7. Greenworks 48V 20″ Push Mower
The 20-inch steel-deck mower that keeps running reliably season after season.
Greenworks built this one around a smart battery idea: two 24V POWERALL batteries combine to deliver 48V of power, so you stay on the 24V platform that runs a whole family of tools. The durable steel 20-inch cutting deck covers ground efficiently, and the highly efficient brushless motor gives you more torque and quieter operation while sipping power. Runtime reaches up to 45 minutes with two fully charged 4Ah batteries, which owners say handles a third of an acre on a single charge.
The 4-in-1 system is the standout feature: you can mulch, rear bag, side discharge, or hit the Turbo button for maximum power during leaf pickup. Four cutting height positions span from 1.38″ to 4″, and the one-lever adjuster makes changes quick. At 67.2 lbs, it is a substantial machine, but the cut quality and reliability more than make up for the weight — some customers note flawless operation after two years of hard use.
Buyers consistently compare it favorably to gas mowers on cut quality and ease, and it handles thick, wild grass without clogging. The main limitation is that the 4Ah batteries are adequate but not generous — for larger yards, owners recommend buying a spare pair of 5Ah batteries to finish in one session. It is not self-propelled, but most find it easy to push even on slopes.
Why it stands out: proven long-term reliability, a wide steel deck, and a 4-in-1 system that handles every season.
The honest note: plan for a spare battery pair if your yard approaches half an acre, and be ready for its 67.2-pound heft.
8. Worx 40V 21″ 3-in-1 Mower (WG752)
The 21-inch tech-forward mower with a vented deck that stops clumping.
Worx packs this mower with technology that genuinely changes how it cuts. AeroDeck technology uses a vented design to boost air volume in the cutting deck, preventing clogs and clumping while maximizing bag collection. IntelliCut sensors automatically dial up the cutting speed when you hit thick grass and dial it back in thinner areas to conserve runtime — a clever way to stretch the included two 5.0Ah PowerShare Pro batteries to about 50 minutes.
The brushless motor 2.0 delivers 40% more power and 10% longer runtime than first-gen brushless motors, making this a strong choice for lawns up to half an acre. A single 7-position lever adjusts cutting height from 1.5″ to 4″, and the fully collapsible handle allows for space-saving vertical storage. The 3-in-1 functionality covers mulching, bagging, and rear side-discharging with the included mulch plug and discharge chute.
The PowerShare batteries work with 140+ Worx tools, making this a smart add if you’re already in the Worx ecosystem. Owners love the quiet operation and light push, with one noting they “almost look forward to mowing” because it stores upright and takes up so little garage space. Feedback on battery life and maneuverability is mixed, and the batteries are a bit hard to remove, but the cut quality and airflow design earn high marks.
The Highlights
- Performance is the most-praised attribute, with strong cut quality
- Ease of use and assembly score high
- Quiet operation and lightweight push
What to Weigh
- Battery life gets mixed feedback — some find it great, others short
- Batteries are a bit hard to remove from the mower
Choose this if: you want smart cutting tech, a half-acre range, and batteries that work across a whole tool lineup.
Think twice if: you want self-propelled assistance — this is a push mower, though a light one.
9. SKIL PWR CORE 40 20″ Self-Propelled (SM4910C)
The self-propelled 20-incher that does the pushing for you, with a speed dial.
If pushing a mower is the part you dread, this SKIL takes that chore away. The variable speed self-propel system lets you adjust the pace with a dial, so you set a comfortable walking speed and let the mower do the work. It runs up to 50 minutes on a single charge from the included 40V 6.0Ah battery, which owners confirm handles a third of an acre comfortably.
The digital brushless motor delivers efficient power without the gas hassle, and the push-button start gets you going instantly. A single lever adjusts deck height across 7 settings from 1.5 to 4 inches, and the 3-in-1 functionality covers bagging, mulching, or rear-discharging. The telescoping handle folds easily for vertical storage, keeping your garage floor clear.
Older buyers, including a 72-year-old, specifically praise the easy push-button start and easy turning. The battery is a genuine highlight — owners note it keeps going even after a couple of hours of occasional use, and a 13-month owner says the battery never drained through two yards. The weather-resistant construction adds durability, and the lightweight design makes it easy to maneuver around pool areas and flower beds.
The key strength: genuinely effective self-propulsion plus a battery that outlasts most expectations.
A fair caveat: it can struggle with very thick, wet grass, so keep the blade speed up on damp days.
10. Greenworks 80V 21″ Self-Propelled
The 80-volt power plant that climbs hills and mows in the dark.
This Greenworks steps up the voltage to 80V, which translates to serious torque for slopes and thick grass. It cuts up to half an acre on a fully charged 4.0Ah battery, with owners reporting a 20-minute job uses only a quarter of the charge. The rear-wheel drive and variable speed control provide maximum traction and maneuverability, making it a true replacement for a gas self-propelled mower on hilly lots.
The LED headlight is a genuinely useful addition, letting you mow in the early morning or late evening. Owners say it is 3x quieter than gas — quiet enough that neighbors can’t hear it running. The 4-in-1 system handles mulching, bagging, side discharge, and turbo leaf pickup, so it stays useful through fall. At 75 lbs, it is a heavy machine, but the self-propulsion carries most of that weight for you.
Performance is the most-praised attribute by a wide margin, with ease of use and the self-propelled drive earning strong follow-up mentions. One owner with a city lot reports cutting it on about half a charge, calling the operation “easy compared to my previous gas engine mower.” The main consideration is battery life in the mixed column — for large yards, having a spare battery makes the difference, and a few owners noted the self-propel can lock the wheels if not disengaged early enough.
The big win: 80V power plus rear-wheel drive that handles hills and thick grass without bogging down.
Plan ahead for: a spare battery if your lawn approaches the half-acre mark, and practice disengaging self-propel before backing up.
11. EGO POWER+ 21″ Select Cut (LM2156SP)
The 8.3 ft-lbs torque machine that chews through 8-inch grass like it is nothing.
This is the mower for people who measure success in torque. Reviewers point out cutting 6-8 inch tall grass without the motor bogging down, and the 56V 10.0Ah battery provides up to 75 minutes of runtime on a single charge, covering a third of an acre with power to spare.
The Select Cut multi-blade system lets you customize your cut with interchangeable lower blades: mulching, high-lift bagging, and extended runtime options, plus an upper blade. The Touch Drive self-propel engages with the touch of your palm, and the speed dial is right at your fingertips. Eight cutting height settings adjust from 1 to 4 inches one-handed, and the two-bushel grass bag handles collection. LED headlights and IPX4 weather resistance round out the package.
Buyers who replaced gas Honda mowers praise the cut quality and note that conversation is possible at normal volume while it runs — a huge change from gas. The battery compatibility with all EGO 56V ARC Lithium batteries means owners with other EGO tools can share power. The trade-offs are specific: side discharge is not its strong suit, the plastic wheels feel jarring on rough ground, and the self-propel can be too aggressive for smaller users — one owner described it pulling “like a dog.”
Choose it for: maximum torque, top-tier mulching, and a battery that genuinely lasts 75 minutes.
Be aware: side discharge and the aggressive self-propel are the most-cited quirks, so it shines brightest as a dedicated mulcher.
Understanding the Specs
Voltage (V) and Cutting Torque
Voltage is the electrical pressure that drives the motor, and higher voltage generally means more cutting power. The jump from 40V to 80V matters most in thick, damp, or overgrown grass where a lower-voltage motor might stall. For torque specifically, look for a figure in ft-lbs — the EGO mowers advertise 7.0 and 8.3 ft-lbs to show they can match gas power.
Battery Capacity (Ah) and Runtime
Amp-hours (Ah) tells you the battery’s fuel tank size, not its power. A 10.0Ah battery runs roughly twice as long as a 4.0Ah one at the same voltage. But runtime also depends on grass conditions — tall, wet grass drains batteries faster, and self-propulsion adds draw. Look for mowers with dual batteries so you can hot-swap and keep going.
