How To Choose The Best Battery Charged Lawn Mower
Battery mowers start instantly, need no oil changes, and run quietly, making them a popular gas alternative. Focus on these key specs before you buy.
Match runtime to your actual lawn size
Don’t buy on voltage alone. A 40V mower with a 5.0Ah battery can outlast a 56V with a 2.5Ah pack. Look at the battery’s amp-hour (Ah) rating — that’s the fuel tank. On average, a 4.0Ah battery covers roughly a quarter-acre, while a 7.5Ah pack can stretch to 9,000 square feet.
Cutting width sets your pace
A 21-inch deck mows noticeably faster than a 16-inch one because you cover 2.3x more ground per pass. Small 9-inch mini mowers are for edging and tight corners, not whole lawns. Consider the physical width against your yard’s openness.
Self-propelled vs push
If your yard is flat and under a quarter-acre, a push mower keeps things light. On slopes or with larger lawns, self-propelled drive saves real energy. Check whether the drive is variable-speed and whether the wheels disengage for reversing — both affect daily comfort.
Think about the battery platform
Most brands share batteries across their tool lines. If you already own a drill or trimmer from one brand, buying that brand’s mower means spare batteries work everywhere. This ecosystem value often outweighs any single spec.

In‑Depth Reviews
1. EGO POWER+ LM2135SP Self-Propelled
Our pick — over 4.5★ from 650+ verified ratings; the strongest balance of quality and price.
The gas-replacing 21-incher with a spare 5.0Ah battery for long afternoons
This is the mower owners say finally retired their gas machines — the 56V brushless motor delivers up to 7.0 ft-lbs of cutting torque, which is the spec that beats gas engines on thick grass. The 21-inch deck matches the cutting width you’d get from a premium gas mower, and the included 7.5Ah battery runs up to 60 minutes on a single charge, so a 9,000-square-foot yard is genuinely doable.
The extra 5.0Ah battery ships separately and doubles as a hot-swap mid-lawn. Touch Drive self-propulsion engages with a palm press and adjusts speed with a fingertip dial. The Select Cut system swaps lower blades — mulching, high-lift bagging, and extended runtime — plus an upper blade, so you tune the cut to the season rather than buying new parts.
Buyers report: “Takes about an hour to cut my yard and able to do so on single charge.” That matches the consensus that performance is the standout. The self-propelled feature gets mixed feedback — some find it easy, others report engagement hiccups, so test it on a slope before assuming it does all the work.
What wins owners over
- 60-minute runtime on the 7.5Ah battery you get in the box
- Up to 7.0 ft-lbs torque outcuts most gas mowers
- 7.5Ah battery is compatible with all EGO 56V ARC Lithium tools
- Select Cut blades swap for mulching, bagging, or runtime
What to verify first
- Self-propelled engagement gets mixed feedback in reviews
- Cut quality sometimes leaves stragglers on the pass
- Occasional weak spot: the non-bagging attachment can break early
Reach for this if: you want a true gas replacement with a 21-inch cut and extra runtime for a large yard.
Look elsewhere if: you need a feather-light push mower or have a tiny patch — the self-propel system adds weight and cost.
2. MZK 40V 16-Inch Brushless Push Mower
A light, budget-friendly push mower that punches above its size
Owners call this a “great small battery mower” that’s very light and easy to move around — and one even says it outperformed a gas mower on overgrown grass. The dual 20V 4.0Ah batteries pair up for 40V of power, delivering up to 45 minutes of runtime per the spec sheet, which is plenty for a small-to-medium lawn.
The 16-inch cutting width is narrower than the premium picks, with 4 height positions from 1.3 to 2.6 inches for seasonal adjustments. What makes it a value standout is the complete kit: two batteries, a single-port charger, and an 8-gallon grass bag. Buyers also note the 2-step safety start is great for homes with kids.
The high praise is for build quality and performance, but the battery life splits owners — some say it’s fine for a mid-size lawn, others report the batteries drain fast in tall grass. This mower suits smaller, flatter yards.
Trimming champ: owners mention mowing 1600 sq ft in 20 minutes with the 13-inch blade, quiet and efficient — though the grass bag may rip, so treat it gently.
Grab this when: you want a sub-16-inch mower with batteries, charger, and bag included at an entry-level price.
skip it if: your lawn is large or you hate swapping batteries mid-mow.
3. RB 40V 9-Inch Mini Cordless Mower
One-hand steering for tight corners, patios, and edging duty
Weighing just 11.5 lbs without the battery, this mini mower is the easiest thing on the list to maneuver — customers note it “moves like a vacuum cleaner” and one even called it the “Lawnborghini on grass!” The high-speed 6000RPM brushless motor makes fine mulch, and the 40V 2Ah battery is rated for small lawns up to 540 sq.ft.
Three cutting heights from 1.2 to 2 inches keep grass healthy, an advanced safety design stops the blade if tilted beyond 20°–70°, and the detachable aluminum handle lets it store upright, saving up to 70% of space. It’s ideal for small, bumpy, or obstacle-heavy lawns.
The thing everyone raves about is functionality and the featherweight feel. Battery life is the mixed note — most get one charge per small mow, but a few report charging quirks, so a backup battery is a smart add for longer sessions.
Edging star: the 9-inch deck is 2.3x narrower than the EGO’s 21-inch, which is exactly why it slips between trees and fences.
Choose this if: you need a one-hand mower that folds flat for a shed, camper, or apartment balcony.
Pass it by if: you expect to mow a full-size lawn in reasonable time — this is a precision tool, not a wide cut.
4. Greenworks 48V 20-Inch Push Mower
A quiet push mower that starts with a button press and stays light
Two 24V PowerALL batteries combine for 48V of power, and the brushless motor delivers more torque with quieter operation than gas. The durable steel 20-inch deck covers ground fast, and up to 45 minutes of runtime handles most front-and-back yards on one charge — owners confirm it mows both in a single go.
Assembly is minimal and the single-lever height adjust makes changing cut simple. The dual-port rapid charger means both batteries top up at once, which is a real time-saver. It works with 200+ Greenworks 24V tools, so if you already own their trimmers or blowers, the batteries cross-platform.
Performance garners the heaviest praise, with buyers noting it’s even rated highly by Consumer Reports. The recurring trade-off: for a 1/3-acre property, the stock 4.0Ah batteries run out about halfway, which is why many owners buy a spare pair — budget that in if your yard is larger.
Owners love
- Button-press start — no pulling a cord
- Quiet enough to listen to music while mowing
- Lightweight feel with easy maneuverability on small slopes
- Compatible with 200+ Greenworks 24V tools
Budget for
- Extra batteries for lawns bigger than a quarter-acre
- 20-inch deck is narrower than some premium competitors
Best for: mid-size yards where quiet, button-start convenience outweighs the need for self-propulsion.
Think twice if: you’d rather have one big battery than manage two packs.
5. CRAFTSMAN V20 20-Inch Push Mower
A low-profile 20-incher that stores vertically and squeezes under obstacles
The low-profile design (10-inch deck at height setting 1) is the defining trick — it slides under shrubs and around obstacles that catch other mowers. The brushless motor provides up to 50 minutes of runtime with two 5.0Ah batteries and two chargers included, which covers a 1/3-acre yard in one go for most owners.
Dual-lever height adjustment spans 1.5 to 3.5 inches, and vertical storage takes 78% less space, so it fits in a closet or lean-to. At 47.9 pounds, it’s among the lighter 20-inch mowers, making transport and maneuvering genuinely easy.
Performance and lightweight are the praise winners, but battery life splits owners — some finish easily, others hit the last 10 feet and drain. Durability gets mixed notes too, with a few reporting plastic parts wearing, so this is best for gentle, level yards.
Space-saver: buyers who store it upright love the 78% vertical-space savings, and one notes it’s “incredibly cool looking” despite being all-plastic.
Pick this for: small, flat yards where the low profile and vertical storage change your daily routine.
Not for: thick, neglected grass or half-acre lots — the torque fades as the battery drains.
6. Worx WG752 40V 21-Inch 3-in-1
Smart sensors auto-tune power as you cross thick and thin grass
This mower adjusts power automatically. IntelliCut sensors automatically dial cutting speed up for dense grass and back for thin areas, so you never waste battery on easy passes. The Aerodeck vented design boosts airflow to prevent clogs and clumping while maximizing bag collection.
The Brushless Motor 2.0 delivers 40% more power and 10% longer runtime than first-gen brushless motors, with up to 50 minutes on the included dual 20V 5.0Ah PowerShare Pro batteries. It’s rated for lawns up to 1/2 acre, and a single 7-position lever adjusts cutting height from 1.5 to 4 inches.
Three-in-one functionality handles mulching, bagging, and rear side-discharge with the included plug and chute. The fully collapsible handle and onboard charge-level indicator round it out. Owners praise performance first, noting it handles 4-5 inches of high grass without issues.
Smart power: reviewers point out it cuts as well as their old gas mower, runs the whole yard on one charge, and the motor visibly boosts in heavy grass.
Reach for it if: you want 3-in-1 flexibility and auto-adjusting power on a half-acre without self-propulsion.
Look elsewhere if: you insist on self-propelled drive or need replacement blades available now.
7. Worx WG760 40V 21-Inch Self-Propelled
The self-propelled sibling with variable speed for sloped terrain
If the WG752 above is the push version, this is the one that does the legwork — self-propelled with variable speed up to 3.7 MPH. Owners say the forward-spinning wheels don’t fight you when pulling back, which makes reversing far less annoying than on some rivals.
It shares the same Aerodeck and IntelliCut tech, plus the Brushless Motor 2.0 that’s 40% more powerful and runs 10% longer than first-gen motors. Up to 50 minutes of runtime on the pair of 5.0Ah PowerShare Pro batteries covers a quarter-acre with about 50% battery left, per owners.
Performance and cut quality earn the top praise, and seniors in particular find it easy to use. Battery life is the mixed note — it’s fine for standard cuts but drains quickly in thick grass, so keep the second battery charged for the whole yard.
Hill helper: buyers on slopes appreciate that self-propel only kicks in when needed, and one calls it “the best mower I ever bought” for cut quality.
Choose this over the WG752 if: your yard has slopes and you want the drive to carry the weight.
pass on it if: you want the lightest possible machine — self-propel adds pounds.
8. Greenworks 80V 21-Inch Self-Propelled
80V torque with rear-wheel drive for steep hills and thick grass
This is the high-voltage answer for tough lawns — the 80V brushless motor provides more torque and quieter operation, with an LED headlight for early-morning or late-evening mowing. The durable 21-inch steel deck cuts up to 1/2 acre on a fully charged 4.0Ah battery, and the listed runtime stretches to 2 hours.
Rear-wheel drive with variable speed control delivers maximum traction on hills, which owners confirm — thick wet St. Augustine grass gets cut “like butter.” The 4-year warranty and compatibility with 75+ Greenworks 80V tools make it a long-term ecosystem investment.
Performance and self-propelled ease are the most-praised aspects, with the 80V power drawing consistent compliments. Battery life is the honest trade-off: some owners get multiple mowings per charge, others find it runs about half as long as claimed on dense grass.
Hill climber: shoppers say a 20-minute mow uses just 1/4 battery, and reversing is easiest by lifting the rear wheels to disengage drive.
Get this for: hilly, thick lawns where torque and traction matter more than portability.
Pass if: you want lighter weight — at 75 pounds it’s a workout to load into a truck.
9. Cat DG670 60V 21-Inch Push Mower
A dual-battery bay keeps a spare pack ready for large lawns
The standout feature is the dual battery port — you carry two batteries on board, and when one drains, the other takes over without stopping. That’s a real time-saver on bigger lawns, and the included 60V 5.0Ah pack runs the whole front and back yard on a single charge for many owners.
Brushless Motor 2.0 produces 40% more power and 10% longer runtime than standard brushless motors, with TorqLogic automatically boosting power for dense grass and dialing back for thin conditions. The 3-in-1 lever switches between bagging, mulching, and side discharge, and the deep deck’s rising angle boost air flow for complete bag fill.
The battery life earns the most praise here. Fit matters though — quality feedback is mixed, with some calling it excellent and others reporting units that won’t start, so buy from a seller with easy returns and test it on arrival.
Second battery ready: a dual-battery design cuts downtime, and LED lights plus a battery indicator make it easy to track power mid-mow.
Ideal for: owners who want a spare battery without stopping to swap during a long cut.
Consider carefully if: you need absolute reliability — quality reports are split.
10. EGO LM2134SP-2 21-Inch Self-Propelled
Two 6.0Ah batteries deliver up to 100 minutes of run time
This is the runtime king — two included 56V 6.0Ah batteries push the mower to up to 100 minutes on a single charge, which is double the EGO bundle above. Owners mow a 1/4-acre lawn in 50 minutes of mulching with self-propel and still have one full battery left.
Touch Drive self-propulsion uses palm pressure to engage, with variable speed from 0.9 to 3.1 miles per hour. Eight cutting height positions span 1 to 4 inches via a single lever. The high-efficiency brushless motor keeps vibration low, and bright LED headlights extend usable hours into dusk.
Performance and battery life lead the praise, with the 7.0 ft-lbs of torque beating most gas mowers. The honest downside is the thumb button for self-propel — some buyers report hand cramping on long cuts, and the turning radius on rear-wheel drive takes practice.
Why it wins
- Up to 100 minutes of runtime across two 6.0Ah batteries
- 7.0 ft-lbs cutting torque exceeds most gas mowers
- 0.9–3.1 MPH variable speed self-propulsion
- Compatible with all EGO 56V ARC Lithium tools
Watch for
- Thumb button can cause hand cramping over long sessions
- Rear-wheel drive makes tight turns trickier
- Bag is on the smaller side for large lawns
Choose this if: you want the most runtime possible in one kit for a big, open yard.
Look elsewhere if: hand comfort is critical and you mow for over an hour straight.
11. Honda HRX-BE 21-Inch Self-Propelled
Honda’s legendary build quality, now with a 12Ah lithium battery
This is the battery mower for people who’ve trusted Honda gas engines for decades — the HRX-BE offers the same torque as the GCV gas series, with a 12Ah lithium-ion battery delivering up to 45 minutes or about 0.37 acre per charge. Two battery bays mean you can double runtime with a second pack, and e-Select Drive gives precise speed control from 0 to 4 mph.
The 4-in-1 Versamow system mulches, bags, discharges, and leaf-shreds with no attachments, using the twin-blade MicroCut System’s four cutting surfaces. Seven cutting heights span 0.75 to 4 inches via dual levers — the 0.75-inch minimum is ideal for Bermuda grass. The 5-year residential warranty and nationwide service network are the real premiums here.
Owners praise performance and battery life, with one reporting a full acre mowed on dual batteries with auto-switch. The self-propulsion gets mixed feedback, and there’s a known factory defect risk on the wheel adjustment lever, so inspect it carefully on delivery.
Built for the long haul: buyers call it a “powerful, solid machine” that replaces a 25-year gas mower, with parts and support available nationwide.
Worth it for: Honda loyalists who want gas-grade power plus a 5-year warranty and service network.
Not for: budget-first shoppers or anyone who won’t inspect the wheel lever on arrival.
Understanding the Specs
Battery voltage vs amp-hours
Voltage (like 40V or 56V) is the pressure behind the cut — higher usually means more torque for thick grass. Amp-hours (Ah) is the fuel tank size — a 7.5Ah battery holds more energy than a 4.0Ah pack at the same voltage. Runtime claims like “60 minutes” assume perfect conditions, so expect less in tall or wet grass.
Cutting width and height range
Cutting width in inches tells you how much ground you cover per pass — 21 inches is roughly 2.3x wider than a 9-inch mini mower. Cutting height range (for example, 1 to 4 inches) matters for grass type: Bermuda likes a low 0.75-inch cut, while cool-season grasses prefer 3-4 inches. More positions give you finer control.

Final Thoughts: The Verdict
If you want one dependable pick, the battery charged lawn mower winner is the EGO LM2135SP because it pairs a 21-inch cut with a 7.5Ah battery for up to 60 minutes of runtime — enough for a 9,000-square-foot yard. If you want maximum runtime in one kit, the EGO LM2134SP-2 doubles that with two 6.0Ah packs. And for a balance of price and quiet power on a mid-size lawn, the Greenworks 48V is the value pick that starts with a button press.
