If you searched for the consumer reports best battery lawn mower, this guide helps you compare battery mowers on the points that change the buying decision. It does not use Consumer Reports ratings or scores. Instead, it works from the specifications stated in each product listing: cutting width, height range, battery contents, listed runtime and item weight. Many cordless listings are sold without a battery or charger, so the first decision is what comes in the box. Use the picks below to match a mower to your yard, then confirm the details on the listing before you order. Where a listing leaves a detail out, this guide says so rather than filling the gap.

Quick answer

Choose by yard size first, then by what the listing says is included. For a very small yard, the RB 40V 9-inch mower has the narrowest cut in this set. For a 16-inch deck with two batteries and two chargers listed, the KOMASTY mower is the closest match. For larger lawns, the Greenworks 60V self-propelled model fits best, because its kit includes two 4.0 Ah batteries and it has self-propelled drive. The EGO LM2114 is the best overall pick for most mid-size lawns, since its listing states that both the battery and charger are included. If you already own DeWalt 20V MAX packs, the Houselife mower is worth a look, but its listing says it is tool only.

What matters most for this search

Readers who type best battery lawn mower consumer reports want a side-by-side view they can check against the listing. Readers who look for a best battery powered lawn mower consumer reports comparison, or for consumer reports on battery powered lawn mowers, have the same need. These five points change the choice more than the maker does.

What comes in the box

Many cordless mowers are sold as tool only, which means the mower arrives without a battery or charger. Some listings in this set state that the battery and charger are included. The Houselife listing states the opposite. The RB listing has a title that mentions a battery and charger, yet its details do not confirm them. Read the included-components details and the bullet points before you compare features.

Cutting width and yard size

Cutting width is the deck width the listing states. The widths in this set run from 9 inches on the RB mower to 21 inches on the EGO LM2114. A wider deck covers more lawn per pass, but it also adds weight and needs more storage space. A common rule of thumb is to match the deck to the lawn you mow most often, not to the largest number on the page.

The US consumer safety standard for walk-behind power lawn mowers defines the category with a minimum cutting width of 12 inches. By that definition, a 9-inch deck falls below the threshold. The standard’s stated purpose is to reduce injury from contact with the rotating blade, not to rate battery runtime. The standard, 16 CFR 1205.1, sets out the definition.

Battery platform and listed runtime

Each battery platform belongs to its own brand’s tools. The EGO listing ties its battery to EGO 56V ARC Lithium batteries, and the Houselife listing names DeWalt 20V MAX packs. Runtime figures such as 55 minutes for the EGO and 45 minutes for the iToolMax are manufacturer claims. The Greenworks 16-inch listing says runtime varies with grass condition and operator technique. Treat every listed runtime the same way.

A voltage figure alone does not settle runtime either. Lithium-ion cells nominally run at 3.6 or 3.7 volts, and battery sizes are not standardized, so you have to read amp-hours and the listed runtime together. For a deeper look at voltage and amps, see lawn mower battery voltage and amps.

Weight and storage

Weight decides whether you can lift the mower into a shed or a car. The listed weights run from 9.9 pounds for the iToolMax to 82 pounds for the EGO LM2114. The Litheli and Houselife listings describe folding frames or handles, which help in tight garages. The RB listing describes upright storage and gives a weight of 11.5 pounds without its battery, so the weight with a battery is higher.

If a corded alternative makes more sense for your storage, compare the corded options in small electric lawn mower with bag.

Height range and conflicting figures

Cutting height is usually set with one lever or with a mechanism on each wheel, according to general lawn mower reference material. Listed ranges differ from model to model. The EGO listing gives 1.25 to 4 inches across seven positions, and the Houselife listing gives 0.98 to 3 inches across six positions.

Two listings in this set contain conflicts inside the same listing. The Litheli specification table gives a minimum cutting height of 13 inches, while its bullets give 1 inch to 2.5 inches. The iToolMax model number field reads Cordless Grass Trimmer under a lawn mower title. When figures conflict, rely on neither number and confirm the listing before you buy.

How to choose a battery lawn mower

Use a short set of rules. Each rule ties one listing detail to one yard situation.

• Choose a listing that states the battery and charger are included if you do not already own packs for that platform.
• Choose a deck of 16 inches or wider when your lawn needs fewer passes. Choose a 9-inch or 13-inch deck for small patches and tight edges.
• Choose a lighter model, such as the 9.9-pound or 22-pound listings, if you must carry the mower up steps or into a shed.
• Choose a heavier model only if you mow mostly flat ground and want self-propelled drive or a larger deck.
• Choose a listing where the model number and specifications agree. If they conflict, skip that model until the seller clarifies it.

Checklist before you buy

• Read the included-components line first. If the listing does not state what is in the box, assume nothing is included until the listing confirms it.
• Confirm the battery platform. Note the brand the listing names, and whether it ties the battery to one platform only.
• Check the cutting width against your largest mowing area, then decide how many passes you want to make.
• Compare the minimum and maximum cutting heights. If the specification table and the bullets disagree, ask the seller or the manufacturer for the correct range.
• Note the item weight, and whether you can lift the mower into your car or shed without help.
• Read the warranty line. Some listings state a 1-year or 3-year term, and others state nothing.

Seven picks follow, with one model per brand. If your needs differ from the picks below, compare other listings against the same checklist.

Side-by-side view of the picks

The table compares only the figures each listing states. Where a listing conflicts with itself, the cell says so.

Pick	Cutting width	Height range	Battery and charger	Item weight	Warranty stated
EGO LM2114	21 inches	1.25 to 4 inches, 7 positions	Battery and charger included	82 pounds	5-year tool, 3-year battery
Greenworks 60V self-propelled	20.28 inches	1 to 4 inches, 7 positions	Two 4.0 Ah batteries in the kit; charger not stated	65 pounds	4-year
Litheli	13 inches	Table: 13 inches minimum; bullets: 1 to 2.5 inches	4.0Ah battery and matching charging cable listed; battery figures conflict	24 pounds	3 years for the whole machine
RB 40V 9-inch	9 inches	1.2 to 2 inches, 3 positions	Title states a battery and charger; details do not confirm them	11.5 pounds without battery	Not stated
KOMASTY 16-inch	16 inches	1.37 to 2.95 inches, 5 positions	Two 4.0Ah batteries and two chargers	Not stated	Not stated
iToolMax	9 inches	1 to 2.2 inches, 3 positions	Two 21V batteries in the bullets; charger not stated	9.9 pounds	Not stated
Houselife	14 inches	0.98 to 3 inches, 6 positions	Tool only; battery and charger not included	22 pounds	1 year

Two patterns stand out. The widest decks, at 20.28 and 21 inches, carry the heaviest item weights that a listing states. The lightest listed weights, 9.9 and 11.5 pounds, come with the narrowest decks, and a narrow deck covers less ground per pass.

The battery column is the one to read twice. Only two listings name both a battery and a charger in their contents, the EGO and the KOMASTY. Several others leave the charger unstated or contradict the title.

Session length against listed runtime

Assume a mowing session of 45 minutes.

The EGO LM2114 listing states up to 55 minutes of runtime on a full charge. That is a manufacturer claim, so treat the margin as an estimate: 55 – 45 = 10 minutes. On paper, one charge covers the session with 10 minutes to spare.

The KOMASTY listing states up to 10 minutes of runtime on its two packs. Under the same 45-minute session, the gap is 45 – 10 = 35 minutes. You would need a recharge partway through, and the two chargers listed let both packs charge at the same time.

The lesson is simple. Compare a listed runtime with your own session length, then leave a margin for tall grass or uneven ground.

When a battery mower is the wrong choice

For some readers, a battery mower is not the right purchase. The listings in this set point to four situations where you should look elsewhere or wait.

• Your lawn is larger than the coverage the listing states. The RB listing says it suits lawns up to 540 square feet, so a bigger yard calls for a wider deck or a different tool.
• You cannot lift or move the heavier models. The EGO listing gives 82 pounds and the Greenworks listing gives 65 pounds, so plan for a ramp or a second person.
• You already own a corded mower and have an outlet near the lawn. Compare those options in pros and cons of electric mower before you commit.
• You do not want to plan around charging time. The EGO listing states an 80-minute charge for its 6.0Ah battery, so a long mow may require a pause or a second battery.

Common mistakes

Buying a tool-only listing and expecting a working mower. The Houselife listing states it is tool only, so you must add packs and a charger. The RB listing needs the same check before you order, because its details do not confirm the battery and charger.

Treating runtime as a promise. The 55-minute EGO figure and the 45-minute iToolMax figure are both manufacturer claims, and real results depend on grass and terrain. For wet-grass conditions, read electric lawn mower in wet grass.

Choosing by deck width alone. A 21-inch EGO deck does not help if its 82-pound item weight means you cannot move it to the lawn.

Ignoring a model number that does not match the title. The iToolMax model field reads Cordless Grass Trimmer, so confirm the exact model before you buy.

Using the wrong charger. The Litheli listing warns to use only the original U20 charger. General battery charger reference material notes that some battery types cannot withstand overcharging and can be damaged.

Mixing battery platforms. Each listing ties its battery to one platform. The DeWalt compatibility on the Houselife listing requires two 20V MAX packs, not one.

Battery storage and care

The RB listing says to remove the battery when the tool is not in use, and to store it in a dry, well-ventilated place. Follow the manufacturer’s manual for charging and storage on every model in this guide. Before any blade work, disconnect or remove the battery first.

FAQ

Does this guide use Consumer Reports ratings?

No. The picks come from the specifications stated in each listing. If you want a ratings-based comparison, check the Consumer Reports website directly and compare its findings with the listing details here.

What should I check first on a battery mower listing?

Check whether the battery and charger are included, the cutting width, the height range and the item weight. If two fields disagree, treat both numbers as unconfirmed until the listing is clarified.

Are listed runtimes reliable?

They are manufacturer claims. Real runtime depends on grass condition, cutting height and terrain, so use the listed figure as a starting point for your own session length.

Which battery mower suits a very small yard?

The RB 40V 9-inch listing states a 9-inch cut and a suitable lawn size of up to 540 square feet. Confirm whether the battery and charger are included before you order, because the listing details do not confirm them.

Can I use another brand’s battery in a battery mower?

Usually not. Each listing ties its battery to its own platform. The EGO listing names EGO 56V ARC Lithium batteries, and the Houselife listing names DeWalt 20V MAX packs. Check the listing before assuming any pack fits.

How should I handle the battery and the blade?

Follow the manufacturer’s manual. Remove the battery before you touch the blade, and keep the packs stored as the manual describes.

Bottom line

For most mid-size lawns, choose a listing that states both the battery and charger are included, then check the deck width and the item weight. For very small patches, choose a narrow model such as the RB or Litheli, after you confirm what is in the box. For larger lawns that need self-propelled drive, choose the Greenworks 60V kit. Skip any listing whose figures conflict until the seller corrects them.
