EWORK 40V 14-Inch Cordless Lawn Mower with Dual 4.0Ah Batteries and Fast Charger
This compact mower excels for homeowners with small lawns, offering a lightweight design and quiet operation that stand out against bulkier options like the Wild Badger. Its dual 4.0Ah batteries ensure longer runtime without sacrificing maneuverability, making it ideal for quick, routine jobs. Compared to the Wild Badger’s 18-inch deck, the 14-inch cut is less suited for large areas, but it compensates with easier storage and transport. The included fast charger means less downtime between uses, though the battery life may fall short for larger yards. Safety features like dual triggers add peace of mind, but the limited deck size and runtime are tradeoffs for its portability.
Pros:- Lightweight and easy to maneuver
- Quiet operation suitable for residential areas
- Complete kit with batteries and fast charger included
- Adjustable cutting heights for versatile trimming
Cons:- Limited to small yard sizes
- Battery runtime may be insufficient for larger lawns
Best for: Homeowners with small yards who prioritize quiet, lightweight equipment for quick jobs
Not ideal for: Larger yard owners or those needing extended runtime for extensive mowing sessions
- Battery:2 x 4.0Ah lithium batteries
- Motor:All-copper 3800RPM
- Cutting Deck:14 inches
- Cutting Heights:7/8″ to 2-7/16″ (6 positions)

- Grass Catcher:9-gallon capacity
Our verdict“This mower is best suited for small yard owners seeking convenience and quiet operation without sacrificing portability.”
13 Inch Cordless Lawn Mower, 40V Electric Lawnmower for Garden, Patio, Yard
This 13-inch mower packs a punch with a 1200W brushless motor, making it a strong choice for homeowners with small to medium-sized yards up to 300㎡. Its dual batteries extend runtime, but compared to the larger EWORK model, it sacrifices deck size for easier storage and handling. The adjustable height from 25mm to 75mm allows for tailored lawn aesthetics, yet its runtime of up to 40 minutes may fall short for larger areas. The lightweight design enhances maneuverability, but the absence of foldable features could limit storage options. Overall, it balances power and portability well, though it’s less suited to extensive mowing jobs.
Pros:- Powerful 1200W brushless motor
- Adjustable height for customized lawn look
- Dual batteries provide extended runtime
- Lightweight and easy to maneuver
Cons:- Limited to small to medium-sized lawns
- Runtime may be insufficient for larger yards
Best for: Gardeners with small to medium yards seeking a powerful, portable mower
Not ideal for: Owners of large lawns needing longer runtime and bigger cutting decks
- Cutting Deck Width:13 inches
- Adjustable Height:25mm to 75mm
- Motor Power:1200W brushless
- Battery:2 x 20V 4.0Ah
- Runtime:up to 40 minutes
- Grass Collection Capacity:30L
Our verdict“This mower is a solid choice for homeowners balancing power with ease of use on small to medium properties.”
Wild Badger Power 40V 18-Inch Brushless Cordless Electric Lawn Mower
The Wild Badger’s 18-inch deck makes it more suitable for medium yards, offering greater coverage than smaller models like the EWORK or the Greenworks 17-inch. Its five adjustable heights and multiple clipping modes—bagging, mulching, rear discharge—add versatility for different lawn conditions. The foldable handle enhances storage, making it ideal for those with limited space. However, its 37.5 lbs weight can challenge users with limited strength, and runtime varies significantly with conditions, which may not satisfy those with large or complex yards. Compared to the compact Greenworks options, it balances power and size but requires more storage space.
Pros:- Versatile clipping modes including mulching
- Foldable handle for compact storage
- Includes battery and fast charger
- Good coverage with 18-inch deck
Cons:- Runtime varies with conditions
- Heavier at 37.5 lbs for some users
Best for: Homeowners needing a versatile, easy-to-store mower for medium-sized yards
Not ideal for: Large yard owners who require extended runtime or heavy-duty durability
- Power Source:40V Battery
- Blade Size:18 inches
- Cutting Heights:5 positions
- Clipping Modes:Bagging, mulching, rear discharge
- Battery Included:Yes
- Battery Capacity:4.0Ah
- Weight:37.5 lbs
- Warranty:3 years
Our verdict“Ideal for medium yards where versatility and storage convenience are priorities over maximum runtime.”
MZK 40V 16-Inch 2-in-1 Cordless Lawn Mower
The MZK 16-inch mower offers a practical solution for small to medium lawns, with dual 20V batteries that extend mowing time to about 30 minutes. Its 2-in-1 design allows switching between bagging and mulching, providing flexibility for different yard conditions. Weighing less than many larger models, it’s easy to handle and ideal for quick, light-duty jobs. However, the runtime limits its use on larger lawns, and compatibility issues with other tools may be a drawback for users invested in a multi-brand ecosystem. Compared to the larger Greenworks models, it’s less suited for extensive jobs but excels in convenience and quick setup.
Pros:- Lightweight and easy to handle
- Dual batteries extend mowing time
- 2-in-1 design for mulching and bagging
- Simple assembly and operation
Cons:- Limited runtime for larger lawns
- Batteries are not compatible with other tools
Best for: Homeowners with small to medium yards who want a lightweight, versatile mower
Not ideal for: Large yard owners needing longer runtime or compatibility with other tools
- Power Source:2 x 20V lithium-ion batteries
- Cutting Width:16 inches
- Cutting Height Adjustment:4 positions (1.3 to 2.6 inches)
- Battery Runtime:Up to 30 minutes
- Bag Capacity:30L
- Weight:Not specified
Our verdict“This mower works well for small projects and quick maintenance but isn’t designed for large or prolonged mowing sessions.”
XYT-TECH 40V OP40601 Replacement Battery for Ryobi 40V Lithium Tools 5.0Ah
The XYT-TECH 5.0Ah battery offers extended runtime for those already invested in Ryobi’s 40V ecosystem, including lawn mowers, trimmers, and blowers. Its larger capacity means longer operation between charges, which is especially valuable for users tackling larger or multiple projects. Compared to the smaller batteries in other models, it provides a clear advantage in endurance but is limited to compatible Ryobi tools, unlike universal batteries. The built-in safety features and LED indicator add convenience and durability. However, it’s not suitable for non-Ryobi tools and requires a compatible charger, making it less flexible for multi-brand users.
Pros:- Long-lasting 5.0Ah capacity
- Compatible with a broad range of Ryobi 40V tools
- Built-in safety safeguards
- LED indicator for monitoring
Cons:- Limited to Ryobi 40V tools
- Runtime may vary with heavy-duty use
Best for: Ryobi users needing longer runtime for multiple or larger outdoor tools
Not ideal for: Non-Ryobi owners or those with only small-scale yard needs
- Battery Capacity:5.0Ah
- Voltage:40V
- Model Number:OP4050
- Included Components:1 Replacement Battery
- Warranty:1 Year
Our verdict“This battery is a strong choice for dedicated Ryobi users seeking extended outdoor tool operation.”
Greenworks 40V 17-inch Push Lawn Mower with 4.0 Ah Battery and Charger
This model stands out for its balanced combination of power, versatility, and runtime, making it the best overall choice for small to medium yards. Its 17-inch deck and brushless motor deliver quieter operation and higher torque than some 16-inch competitors, like the Greenworks 40V 16-inch model, but it sacrifices some maneuverability and compactness. While it offers multiple height adjustments and mulching or bagging options, its runtime of up to 35 minutes may fall short for larger areas, and customer ratings are below average at 3.7/5, indicating room for quality improvements. Still, the 3-year warranty provides peace of mind for typical residential use. Compared with smaller decks, this mower offers better coverage without the bulk of larger professional models, making it ideal for those with a few medium-sized lawns to maintain.
Pros:- Balanced 17-inch deck for efficient coverage
- Quiet brushless motor offers higher torque and less noise
- Multiple height and mulching/bagging options for versatility
- 3-year warranty adds durability assurance
Cons:- Customer rating below average at 3.7/5
- Limited runtime of 35 minutes for larger yards
- Designed primarily for small to medium lawns, not suitable for extensive areas
Best for: Homeowners with small to medium-sized yards who want a quiet, versatile, and reliable mower
Not ideal for: Lawn care professionals or owners of large properties who need longer runtime and broader coverage
- Battery Voltage:40V
- Cutting Width:17 inches
- Battery Capacity:4.0 Ah
- Runtime:Up to 35 minutes
- Motor Type:Brushless
- Warranty:3 years
Our verdict“This mower suits homeowners with modest lawns seeking quiet operation and versatility, but it may fall short for large or demanding yards.”
Greenworks 40V 16-inch Push Lawn Mower with 4.0 Ah Battery and Charger
This mower makes the most sense for gardeners prioritizing ease of use and extended runtime, offering up to 45 minutes of cordless operation. Its 16-inch deck is slightly smaller than the 17-inch model, but the lightweight design significantly improves maneuverability—ideal for small yards or tight spaces. While its runtime surpasses the 17-inch Greenworks model, the 2-hour charge time might be inconvenient for those needing quick turnarounds. Its adjustable cutting height and 2-in-1 mulching or bagging system provide versatility without adding weight. Compared to the 16-inch model without a charger or warranty, this version offers more value for those seeking dependable, eco-conscious yard work. The tradeoff is a slightly smaller deck, which may extend mowing time on larger lawns.
Pros:- Lightweight and easy to maneuver
- Up to 45-minute runtime for extended use
- Adjustable height and versatile 2-in-1 system
- Includes battery, charger, and warranty for peace of mind
Cons:- Longer charging time of 120 minutes
- Limited deck size may prolong mowing large lawns
- Runtime could decrease with thick or wet grass
Best for: Small yard owners who value lightweight design and longer runtime for easier handling
Not ideal for: Users with large or heavily overgrown lawns, as the 16-inch deck and runtime could be limiting
- Voltage:40V
- Cutting Width:16 inches
- Battery Capacity:4.0 Ah
- Runtime:Up to 45 minutes
- Charge Time:120 minutes
- Cutting Height Range:1-1/4″ to 3-3/8″
- Warranty:3 years
Our verdict“This mower fits homeowners who prioritize ease of use and longer cordless operation over larger coverage areas.”
Greenworks 40V 16-inch Push Lawn Mower with 4.0 Ah Battery and Charger
This lightweight, cordless mower excels for users who need easy handling and quick setup. Its 16-inch deck and adjustable height make it suitable for small to medium lawns, similar to the previous 16-inch Greenworks model but without the longer runtime. Its lightweight design reduces user fatigue, especially during extended mowing sessions, and it is compatible with other Greenworks 40V tools, making it a flexible choice for existing Greenworks users. The main tradeoff is its limited runtime, which may not be enough for larger yards or thick grass, and the specific weight isn’t provided, making it harder to gauge portability precisely. Still, for those with manageable lawns, this mower offers a straightforward, efficient solution.
Pros:- Very lightweight and easy to maneuver
- Adjustable height for versatile cutting
- Compatible with other Greenworks 40V tools
- Simple, straightforward operation
Cons:- Limited runtime of only 10 minutes per charge
- No detailed weight specification
- Not suitable for large or demanding lawns

Not ideal for: Lawn owners with large properties or thick, tall grass requiring longer operation times
- Battery Voltage:40V
- Cutting Width:16 inches
- Battery Capacity:4.0 Ah
- Warranty:3 years
- Weight:Not specified
Our verdict“This mower is ideal for those who need a lightweight, easy-to-handle tool for small to medium lawns, but it isn’t suited for larger or more intensive jobs.”
40V Electric Lawn Mower 16″ Battery Powered 2-in-1 Mulching and Bagging
This model offers a quick 10-minute runtime with dual batteries, making it suitable for very small lawns or quick touch-ups. Its 16-inch deck and adjustable height settings provide the flexibility needed for different grass types, while the 2-in-1 mulching and bagging options enhance its versatility. The brushless motor ensures efficient cutting and quieter operation, but the limited runtime and customer rating of 3.4/5 suggest it may struggle with larger or more demanding lawns. Its lightweight design and easy assembly make it appealing for quick jobs or homeowners with small, manageable yards. Compared to longer-running models like the Greenworks 40V 16-inch, this one prioritizes speed and convenience over extended use.
Pros:- Fast charging with dual batteries for quick use
- Lightweight and easy to assemble
- Adjustable height for different grass conditions
- Versatile mulching and bagging system
Cons:- Limited runtime of only 10 minutes
- Customer rating suggests inconsistent quality
- Battery life may be insufficient for larger areas
Best for: Gardeners needing a quick, portable mower for small lawns or sporadic maintenance
Not ideal for: Users with larger lawns or frequent mowing needs, due to its 10-minute runtime and mixed reviews
- Battery Voltage:40V
- Cutting Width:16 inches
- Battery Capacity:2 x 4.0 Ah
- Runtime:Up to 10 minutes
- Charging Time:Fast charge (exact time not specified)
- Cutting Height Adjustment:1.37″ to 2.95″
Our verdict“This mower works best for quick, small-scale jobs rather than routine mowing of larger lawns.”

How We Picked
Products were evaluated based on performance, battery capacity, runtime, build quality, and ease of use. We prioritized mowers with proven battery longevity and reliable cutting performance, especially those offering a good balance between power and runtime. Compatibility and value for the price point also played a key role, ensuring buyers get the most for their investment. The ranking reflects a combination of these factors, highlighting models that excel in real-world use while considering tradeoffs like size, weight, and cost.Factors to Consider When Choosing Cordless Lawn Mower Battery 40v
Choosing the right cordless lawn mower battery 40V involves understanding several key factors. Beyond basic features, it’s important to consider battery capacity, mower size, and compatibility to ensure your mower suits your lawn’s size and your maintenance habits. Making the wrong choice can lead to insufficient runtime or added expenses down the line. Here are the main considerations that will help you select the best fit for your yard and budget.Battery Capacity and Runtime
Battery capacity, measured in amp-hours (Ah), directly impacts how long your mower can operate on a single charge. Higher capacity batteries typically offer longer mowing times but can also add weight and cost. If your lawn is large, prioritize models with at least 4.0Ah capacity or higher to avoid frequent recharges. Keep in mind that runtime also depends on mower efficiency, so a higher-capacity battery may still be a better investment for extensive yard work.
Mower Size and Cutting Width
The mower’s size and cutting width influence maneuverability and coverage. Larger decks (around 16-18 inches) can cut more grass per pass, reducing mowing time for bigger lawns. However, they tend to be heavier and harder to handle in tight spaces. Smaller models excel in tight spots and are easier to store but may require more passes on large areas. Consider your yard’s size and terrain to choose a mower that balances ease of use with efficiency.
Compatibility and Battery Ecosystem
Many brands offer interchangeable batteries within their product lines, which can save money and simplify maintenance. If you already own tools from a specific brand, choosing a mower compatible with that ecosystem makes sense. Conversely, mixing brands may lead to compatibility issues or require purchasing additional batteries. Evaluate your current tools and future expansion plans before committing to a specific system to maximize value and convenience.
Mower Features and Versatility
Features like mulching, bagging, and adjustable cutting heights add versatility to your mower. Some models include 2-in-1 capabilities, allowing you to switch between mulching and bagging easily. These extras can enhance lawn health and tidy-up ease but may come at a higher price or increased weight. Decide which features are essential based on your lawn care routine and how much you’re willing to spend.
Price and Long-Term Value
Budget options may seem attractive initially, but they often compromise on battery capacity, durability, or features. Investing in a slightly more expensive model with a strong battery and sturdy build can pay off with longer lifespan and better performance. Consider the total cost of ownership, including replacement batteries if needed, and weigh that against your lawn’s size and your maintenance frequency.
Frequently Asked Questions
Can I use a 40V battery from one brand with a mower from another?
Generally, 40V batteries are brand-specific due to proprietary connectors and voltage regulation systems. While some third-party batteries claim compatibility, using non-original batteries can risk damage or void warranties. It’s safest to stick with batteries designed for your mower’s brand to ensure proper fit and reliable performance. If you want flexibility, choose a system with interchangeable batteries from the same manufacturer.
How long does a 40V battery typically last on a single charge?
The runtime for a 40V battery varies depending on capacity and mower efficiency. On average, a 4.0Ah battery can power a mower for about 30-45 minutes under normal conditions. Larger capacity batteries, such as 5.0Ah or higher, can extend this to 1 hour or more, making them better suited for larger lawns. Keep in mind that mowing speed, grass thickness, and terrain also influence actual runtime.
Is it worth upgrading to a higher voltage or capacity battery?
Upgrading to a higher-capacity battery can significantly improve runtime, especially for larger lawns. Higher voltage generally provides more power for tougher grass and heavier cutting loads, but may also increase weight and cost. If your yard is extensive or your current battery struggles to last through a session, investing in a higher-capacity or higher-voltage option is often justified. For small yards, sticking with your current setup might be sufficient.
What safety features should I look for in a cordless mower?
Safety features such as blade brakes, automatic shut-off, and easy-to-use safety switches are essential for safe operation. Some models include handles that deactivate the blades when released, reducing accidental injuries. Additionally, sturdy construction and stable wheels help prevent tipping or slipping. Always read safety instructions and choose a model with features that suit your experience level and yard conditions.
How do I maintain my cordless mower’s battery for longevity?
Proper battery maintenance involves storing it in a cool, dry place and avoiding complete discharges or overcharging. It’s best to keep batteries charged around 40-80% during idle periods and avoid exposing them to extreme temperatures. Regularly cleaning battery contacts and following manufacturer guidelines can extend battery life. Proper care ensures you get the most out of your investment and consistent performance over time.
