A battery lawn mower is a cordless mower driven by a removable lithium-ion pack instead of a petrol engine or a mains lead, which is what lets it start on a button and run without fumes or a cord to work around. The best battery lawn mowers Australia sells are matched to lawn area rather than to raw power, so deck width and battery capacity decide the choice far more than the badge does.
The category splits into a few clear types. Kits arrive with a battery and charger included and are ready to mow. Bare tools, sometimes called skins, leave the pack out for buyers who already own a compatible battery platform. Twin-battery mowers run two packs in series for 36V or 40V and hold power better in thick grass, while single-battery mowers stay lighter at 18V or 20V. Mini mowers sit below all of them, built for courtyards.
The figure that decides most purchases is deck width against lawn area: a 32 cm (13 inch) deck is rated for lawns up to roughly 200 square metres (about 2,150 square feet), and every pass beyond that adds time rather than capability. After that, the things worth comparing are the number of cutting heights, whether a battery is included, the runtime a single charge returns, and where the mower will physically live between jobs.
This guide compares ten cordless mowers, from a 22 cm mini built for a courtyard up to a brushless 36V machine with seven cutting heights, setting out deck width, battery arrangement, cutting range and storage for each.

1. Giantz 40V Cordless Lawn Mower 34cm – Best for Small Lawns
Twin 20V lithium packs combine to deliver 40V here, and both slide out for storage or charging indoors. The 340 mm cutting deck is sized for a modest suburban lawn rather than a large block, and the handle folds flat when the job is done.
Six height settings cover everything from a close cut to longer growth, and the mower runs in two modes: catcher bag for tidy collection, or rear discharge when clippings can stay on the lawn. Starting is a single push button.
Running on batteries removes the engine noise and exhaust fumes that make early-morning mowing antisocial. The narrow deck is the limit, so anyone with more than a courtyard and a strip of front lawn should step up to the wider model below.
Pros
- Twin removable 20V packs combine for 40V
- Six cutting height settings
- Catcher bag and rear discharge in one machine
- Foldable handle for flat storage
- Push-button start with no cord to trip over
Cons
- 340 mm deck means more passes on a larger lawn
- Runtime is limited by the two supplied packs
- No self-propelled drive
Key specs: 340 mm cutting width, 40V from twin 20V lithium batteries, six cutting heights, catcher bag and rear discharge, foldable handle
CHECK CURRENT PRICE2. Giantz 40V Cordless Lawn Mower 37cm – Best for Medium Lawns
The wider 370 mm deck is the main difference from the model above, and it takes a noticeable number of passes off a medium-sized lawn. Charging is quoted at one hour, which matters more than it sounds when a mow runs longer than a single battery.
Six height positions and the same dual catcher or rear-discharge arrangement carry over. The handle adjusts for height as well as folding away, and separate carry handles make it easier to lift into a ute or down steps.
A child-proof safety start system is included, which is worth having in a shed that children can reach. Like its smaller sibling it is a push mower, so sloped blocks still take effort.
Pros
- 370 mm deck covers ground faster than the 34 cm model
- One-hour fast charging
- Height-adjustable and folding handle
- Dedicated carry handles for transport
- Child-proof safety start system
Cons
- Still a push mower with no drive assistance
- Twin-pack runtime limits a single session
- Heavier to lift than the narrower model
Key specs: 370 mm cutting width, 40V twin lithium batteries, one-hour fast charge, six cutting heights, mulch or catch, child-proof start
CHECK CURRENT PRICE3. Bosch 36V Cordless Brushless Lawnmower – Best for Larger Lawns
Bosch pitches this one at owners whose lawn has outgrown an entry-level mower, and it ships with a 4.0Ah battery rather than leaving the pack as an extra. The brushless motor is the part that matters over a long mow, since it holds torque better as grass thickens.
Cutting height adjusts across seven stages from 25 mm to 80 mm through a single push button, the widest range in this guide. The 80 mm top setting is genuinely useful for kikuyu and buffalo lawns that suffer if scalped.
ProSilence cuts operating noise by up to 30 per cent against the comparison Bosch quotes, and the Ergoslide handles adjust so taller users are not stooping. It is the most expensive pick here, which only makes sense if the lawn justifies it.
Pros
- Seven cutting heights spanning 25 mm to 80 mm
- Brushless motor holds torque in thick grass
- 4.0Ah battery included, not sold separately
- ProSilence lowers operating noise by up to 30 per cent
- Height-adjustable Ergoslide handles
Cons
- The highest price in this guide
- Overkill for a courtyard or small front lawn
- Small review base at the time of writing
Key specs: 36V brushless motor, 4.0Ah battery included, seven cutting heights from 25 mm to 80 mm, ProSilence noise reduction, Ergoslide handles
CHECK ON AMAZON4. Bosch 18V Cordless Lawn Mower – Best Lightweight Kit
At 7.5 kg this is among the easiest mowers here to carry, turn at a garden bed or lift over a step. Bosch supplies a 4.0Ah battery and a fast charger in the box, so it is ready to use rather than a skin needing a separate platform.
Three cutting heights span 20 mm to 60 mm, fewer stages than the 36V model but enough for a lawn kept on a regular schedule. Manoeuvrability is the selling point rather than raw cutting power.
The light weight comes from a smaller deck and motor, so long or damp grass will slow it down. For a courtyard, a townhouse strip or a garden broken up by paths and beds, that trade is usually worth making.
Pros
- Light at 7.5 kg and easy to manoeuvre
- 4.0Ah battery and fast charger included
- Cutting heights from 20 mm to 60 mm
- Established Bosch 18V battery platform
- Strongest review base of the Bosch picks here
Cons
- Only three cutting height settings
- Struggles in long or damp grass
- Deck is too narrow for a large lawn
Key specs: 18V cordless, 7.5 kg, three cutting heights from 20 mm to 60 mm, 4.0Ah battery and fast charger included
CHECK ON AMAZON5. Husqvarna Aspire 18V Lawnmower – Best for Tight Storage
Husqvarna designed the Aspire around storage as much as cutting, and it is the only mower here that can hang on a wall hook. Fold the handle and it also stands vertically, which frees up most of the floor space a conventional mower occupies.
The 34 cm deck suits small to mid-sized gardens, and the compact frame turns easily in narrow side passages where a wide mower has to be reversed out. It arrives as a kit with a 4.0Ah battery plus a 2.5Ah charger.
Battery operation keeps noise low enough to mow early or late without irritating neighbours, which is a real consideration on a small block. The review base is thin so far, and it sits at the upper end of this guide on price.
Pros
- Stores vertically or hangs on the included hook
- 34 cm deck turns easily in narrow side passages
- Supplied as a kit with battery and charger
- Low noise suits early or late mowing
- Lightweight and compact frame
Cons
- Priced high for a 34 cm deck
- Very few buyer reviews so far
- Small deck limits it to mid-sized gardens at most
Key specs: 18V, 34 cm cutting width, 4.0Ah battery and 2.5Ah charger, folds for vertical storage or wall hanging
CHECK ON AMAZON6. STANLEY FATMAX V20 Brushless Mower – Best Low-Profile Deck
Two V20 batteries run in series to give this mower 36V, and the kit arrives with 4.0Ah cells rather than bare. The detail that separates it is the 28 cm deck height, low enough to slide under garden benches, trampolines and low shrubs that force other mowers to stop short.
A brushless motor drives the blade, and the V20 lithium-ion packs hold charge between jobs without the memory effect that troubled older battery tools. Anyone already invested in Stanley V20 hand tools can share packs across the range.
Buyers should note the product listing mixes in specifications that belong to a blower rather than a mower, so the airflow figures quoted there are best ignored. The mower itself is well reviewed and the low deck is a genuine point of difference.
Pros
- 28 cm deck height reaches under furniture and shrubs
- Two 4.0Ah V20 batteries included
- Brushless motor
- Shares batteries with the Stanley V20 tool range
- Solid review base for a newer model
Cons
- Listing copy includes specifications from an unrelated blower
- Two batteries add weight over an 18V machine
- Bulkier to store than the folding compact models
Key specs: 2 x 18V V20 batteries (36V), brushless motor, 4.0Ah cells and charger included, 28 cm deck height
CHECK ON AMAZON7. RB 40V 13 Inch Brushless Cordless Lawn Mower – Best Value Brushless
More than 1,200 buyers have reviewed this mower, by far the deepest feedback of anything in this guide. A brushless motor spins the blade at 3,900 rpm behind a 32 cm cutting deck, which the maker rates for lawns up to 200 square metres.
The supplied 40V 2.0Ah pack returns about 20 minutes of mowing and takes roughly four and a half hours to recharge, so a second battery is worth budgeting for on anything approaching that 200 square metre figure. Five cutting heights run from 20 mm to 60 mm.
Noise is quoted at 96 dB, and it converts between mulching with the supplied plug and collecting into a 30 litre catcher. Dual push-button starting plus a removable safety key make accidental starts unlikely.
Pros
- Brushless motor at 3,900 rpm
- Rated for lawns up to 200 square metres
- Five cutting heights from 20 mm to 60 mm
- Mulch plug and 30 litre catcher included
- More than 1,200 buyer reviews
Cons
- About 20 minutes of runtime per charge
- Recharging takes roughly four and a half hours
- 96 dB is louder than the quietest picks here
Key specs: 40V brushless, 32 cm cutting width, 3,900 rpm, 2.0Ah battery and charger, five heights 20-60 mm, 30 litre catcher, 96 dB
CHECK ON AMAZON8. Bosch Rotak 18V-32 – Best Bare Tool
This is the skin-only option, sold without a battery or charger on the assumption the buyer already owns Bosch 18V packs. For anyone with a Bosch drill or blower in the shed, it removes the largest part of a cordless mower price.
A brushless motor sits behind a 32 cm blade in a 3-in-1 arrangement that cuts, collects or mulches. The mulch plug returns clippings to the lawn as fertiliser, which suits owners who would rather not bag and bin the cuttings.
The obvious catch is that a buyer without existing Bosch batteries pays more once a pack and charger are added than several complete kits in this guide. Check the shed before ordering.
Pros
- Costs less by leaving out the battery and charger
- Brushless motor
- 3-in-1 cutting, collecting and mulching
- Shares packs with the wider Bosch 18V range
- Well reviewed for a recent release
Cons
- No battery or charger supplied
- Poor value for anyone not already on the Bosch 18V platform
- 32 cm deck suits small to medium lawns only
Key specs: 18V brushless, 32 cm cutting width, 3-in-1 cut, collect and mulch, mulch plug included, battery and charger sold separately
CHECK ON AMAZON9. PowerBlade 350CX 20V Cordless Lawn Mower – Best Compact Kit
A single 20V platform keeps this one simple and light, and the kit price includes a 4Ah battery with a fast charger. It undercuts every other complete kit in this guide while still using a brushless motor.
The 13 inch deck puts it in the same size class as the small Bosch and Husqvarna machines, aimed at courtyards, townhouse lawns and nature strips rather than open blocks. Setup is minimal out of the box.
A 20V pack cannot match the twin-battery machines for sustained cutting power in thick grass, and this is a lesser-known brand than Bosch or Husqvarna. As the cheapest full kit here, it is a reasonable entry point.
Pros
- Least expensive complete kit in this guide
- Brushless motor at an entry price
- 4Ah battery and fast charger included
- Light and simple to handle
- Fine for courtyards and nature strips
Cons
- 20V has less sustained power than twin-battery mowers
- Lesser-known brand than Bosch or Husqvarna
- Small review base
Key specs: 20V brushless motor, 13 inch cutting deck, 4Ah battery and fast charger included
CHECK ON AMAZON10. RB 40V 9 Inch Mini Cordless Lawn Mower – Best for Courtyards
Nothing else here is this small. A 22 cm mulching blade spinning at 6,000 rpm off a 40V 2.0Ah pack is rated for lawns up to 50 square metres, which describes a courtyard or a strip beside a driveway rather than a garden.
Three cutting heights between 30 mm and 50 mm cover normal maintenance, and a flexible ball-head control lets it be pushed one-handed or two-handed. The handle folds down for storage in a cupboard rather than a shed.
It mulches rather than collects, so clippings stay on the lawn. Push it beyond the 50 square metre rating and the small deck and battery will both feel it, but within that limit it is easier to store and handle than any full-size mower.
Pros
- Smallest and easiest to store mower here
- 6,000 rpm on a 22 cm mulching blade
- Flexible ball-head control for one-handed use
- Folding handle fits a cupboard
- More than 300 buyer reviews
Cons
- Rated only to about 50 square metres
- Mulches rather than collecting clippings
- Three cutting heights spanning just 30 mm to 50 mm
Key specs: 40V, 22 cm mulching blade, 6,000 rpm, 2.0Ah battery and charger, three heights 30-50 mm, rated to 50 square metres
CHECK ON AMAZONHow to Choose a Battery Lawn Mower
Match the deck width to the lawn, not the budget. A 22 cm mini mower and a 37 cm push mower cost less than an hour apart in labour on a courtyard, but on a 300 square metre block the narrow deck adds dozens of passes every mow. Measure the lawn once and buy for that number.
Count the batteries, not just the voltage. A mower advertised at 40V usually runs two 20V packs in series, and a 36V machine often does the same with 18V cells. Twin-pack mowers hold torque better as grass thickens, while single-pack 18V and 20V machines stay lighter and easier to lift.
Decide between a kit and a bare tool early. A skin is the cheapest way into a cordless mower only if a compatible battery and charger are already in the shed. Adding both afterwards usually costs more than buying a complete kit from another brand, so check what is already on the shelf before ordering.
Look at the cutting height range, not just the count. Warm-season lawns common across much of Australia, including buffalo and kikuyu, suffer when scalped, so a top setting near 80 mm is more useful than a long list of low settings. Three heights spanning 20 mm to 60 mm is adequate for a lawn kept on a schedule.
Work out where it will be stored before buying. Folding handles, vertical standing and wall hooks are the difference between a mower that fits a townhouse garage and one that blocks it. This is the specification most often ignored and most often regretted.
Plan for charging, not just runtime. A 2.0Ah pack returning about 20 minutes of mowing against a four and a half hour recharge means a second battery, not a longer extension lead. Owners mowing acreage away from a socket sometimes charge spare packs from portable power stations rather than running the mower back to the house.
Frequently Asked Questions
Are battery lawn mowers powerful enough for Australian lawns?
For most suburban lawns, yes. Brushless twin-battery mowers handle buffalo and kikuyu without stalling, provided the grass is cut on a regular schedule rather than left to grow long. Very large blocks, long wet grass and steep slopes still favour petrol or a self-propelled machine.
How long does a battery lawn mower run on one charge?
Around 20 to 40 minutes depending on the pack and how thick the grass is. A 2.0Ah battery sits at the lower end of that range, while 4.0Ah packs and twin-battery mowers run longer. Buying a second battery is the usual fix for a lawn that takes more than one charge.
Is a bare tool cheaper than a full kit?
Only if you already own a compatible battery and charger. A skin plus a new battery and charger from the same brand generally costs more than a complete kit, so a bare tool makes sense for someone already using that platform and rarely for anyone else.
What cutting height should I use?
Higher than most people think for warm-season grasses. Buffalo and kikuyu do better left longer, so a setting near the top of the range protects the lawn through summer. Cutting low repeatedly stresses the grass and encourages weeds.
Do battery mowers need much maintenance?
Far less than petrol. There is no oil to change, no spark plug and no fuel to drain over winter. The blade still needs sharpening, the deck needs clearing of packed clippings, and batteries last longest stored partly charged rather than flat or full.
Can I mow wet grass with a battery mower?
It is best avoided. Wet clippings clog the deck and catcher, the cut is uneven, and the extra load drains the battery faster. If the lawn must be cut damp, raise the cutting height and take narrower passes.
Verdict
For a typical suburban lawn the Giantz 40V Cordless Lawn Mower 37cm is the sensible starting point, pairing a 370 mm deck with one-hour charging and six cutting heights. Owners with a larger block and thicker warm-season grass are better served by the Bosch 36V Cordless Brushless Lawnmower and its 25 mm to 80 mm height range, while anyone mowing nothing bigger than a courtyard will find the RB 40V 9 Inch Mini easier to store than any full-size machine.
