The Best Battery Lawn Mower: Our Choices
Guide: Questions you should ask yourself before buying a cordless lawn mower
What are the advantages of a cordless lawn mower compared to petrol and corded electric mowers?
Flexibility: Unlike its little brother - the electric lawnmower - a cordless lawnmower is not corded.
This is especially an advantage if your garden is winding or you have decorated your green paradise with sculptures, for example. Without a cable, you can't get caught anywhere. And you can't cut or damage it with the sharp blades.
Handling: There is no need to start the engine by pulling the cable, which gets the engine going after what feels like the nineteenth attempt.
You can start the electric motor of your new gardening tool by simply pressing a button. Furthermore, cordless mowers are usually smaller and lighter than petrol mowers, making them easier to handle and more manoeuvrable.
Maintenance: The days of greasy and oily hands are also over. As you can see in the section below, maintenance
is much less complicated and also cheaper.
Environment: In addition to the aspect of noise, the battery-powered lawnmower is also convincing in the area of environmental protection. There are no emissions, so you not only protect the environment, but also your own health.
What does a battery-powered lawn mower cost?
In most cases, a battery-powered lawn mower is significantly more expensive than a petrol or corded electric lawn mower.
In addition, replacement batteries are relatively expensive and cost around €100 depending on the model. It is important to pay attention to the scope of delivery of the mower, because sometimes an additional battery is included.
Sometimes, however, not even the charger is included in the purchase price.
Entry-level cordless mowers start at around 200€. A ride-on mower that has the same equipment as a small car, except for the seat heating, can easily reach the same price. In the professional segment, we are talking about up to almost 20,000€.
How much does it cost to operate a cordless mower?
This also means that the ongoing maintenance costs are significantly lower than with the petrol-powered competitor.
Only normal electricity costs are incurred, which are much lower than the petrol costs for operating a petrol lawnmower. The purchase of a power connection is not necessary for charging a rechargeable battery. This means that you will not incur any additional costs.
When does it start paying off to buy a battery-powered lawnmower?
They are quieter, so they don't disturb the knee-jerk neighbour as much, they are not as harmful to the environment and in most cases you can work on the entire lawn with one full battery charge. Maintenance and upkeep are also kept to a minimum.
So if you have a garden of around 500 m², have already had a row with the neighbour and don't want to get your fingers dirty, a battery-powered lawnmower is ideal.
What functions should my battery-powered lawn mower have? (e.g. mulching function or collection container)
Basically, you should think about what additional functions you want your lawn mower to have. These can also vary between the individual types.
For example, there are lawn mowers with a mulching function, which means that the cut grass ends up in shredded form on the lawn and thus acts as a natural fertiliser.
This is in contrast to lawn mowers with a collection container, which you have to dispose of after or even during your gardening work. Mulching mowers eliminate this extra work.
The possibility of adjusting the handle also differs from model to model. Some can hardly be adjusted at all.
With others, however, you can adjust the handle so much that it takes up hardly any more space than the mower itself when stored.
Especially with battery-powered ride-on mowers, some manufacturers offer an extensive range of additional features that is almost like configuring a new car.
What alternatives are there to battery-powered mowers?
Maintain and care for lawn mowers properly: Petrol mowers require a lot of maintenance compared to electric mowers. Here are some tips on care and maintenance.
Tip 1: Check blade - Only with gloves on
Tip 2: Check oil level - Use only oil recommended by the manufacturer.
Tip3: Replace dirty air filter.
Tip3: When refuelling, do not fill the tank too full, as this may cause a fire.
Tip 4: Check cutting height - Do not cut more than 1/3 of the blade length.
Last but not least, empty the catcher net and clean the housing.
This process results in the production of environmentally harmful CO2. The electric mower works similarly to a battery-powered mower, but is not supplied with power via a battery but via a power cable.
An alternative that is gaining more and more popularity is a robotic mower. Although comparable robotic mowers are relatively expensive, they ensure that Sunday afternoons can be spent relaxing on the lounger.
Mowing robots mow the lawn all by themselves and return to the base station when the battery is low. When the battery is full again, it continues to cut the lawn at the abandoned spot.
For lawns of 1000 square metres or more, we recommend a ride-on mower. This lawn tractor is particularly suitable for a large flat area. The numerous attachment options also open up numerous new areas of application.
Decision: What types of cordless lawn mowers are there and which is the right one for me?
You can choose between different types of battery-powered lawn mowers depending on your needs:
- Battery push mower
- Battery-powered lawn mower with wheel drive
- Electric ride-on mower
Each of the above-mentioned variants offers you different advantages and disadvantages, which you can adapt to your needs. But which one is best suited to become the new heart of your garden tools?
Depending on how large, winding and flat
your garden is, the individual types are better or worse suited to maintaining your individual garden paradise.
To give you an idea of which battery-powered mower is the right one for you, we have presented the different variants below and clearly outlined their advantages and disadvantages.
What exactly is a battery push mower and what are its advantages and disadvantages?
Battery push mowers are lawn mowers that are particularly suitable for small gardens. Although the battery charge is usually sufficient for up to 450m², this is calculated with a walking speed of 3.5 km/h.
The main difference with this version is that the electric motor is only used to drive the cutting blade. There is no wheel drive that sets the mower in motion at the push of a button.
This makes lawn mowing very power-intensive and uncomfortable, as the mower has to be pushed. Especially in uneven gardens, mowing becomes a feat of strength.
By eliminating the additional power source for the wheel drive, the push mower consumes less electricity than all the other types listed here and is therefore cheaper to maintain.
The scope of delivery of lawn mowers usually includes little or no accessories. Also, this type of lawn mower cannot be equipped with additional functions to the same extent as a ride-on lawn mower, for example. The same applies to adjustment options for the handle or the cutting height.
What exactly is a battery-powered lawnmower with wheel drive and what are its advantages and disadvantages?
The battery-powered wheeled lawnmower is the ideal companion for the average German garden. With a range of 300 to 600 m², you can usually cover the entire lawn on a single battery charge.
This type of lawn mower has a more powerful battery installed, as in addition to the mower deck, a wheel drive is also operated via the electric motor.
At the push of a button, the lawn mower moves off by itself and starts the mowing mechanism. This means that the mower only needs to be steered and corrected, because it drives itself.
This makes mowing less strenuous and more comfortable. The wheel drive offers enormous advantages, especially on uneven lawns, as the lawn mower does not have to be pushed.
With high-quality materials and many adjustment options in terms of lawn height or handle, this variant is much more adaptable and versatile. The service life of these models is also much longer.
What exactly is an electric ride-on mower and what are its advantages and disadvantages?
If you have a large garden and want to trim your lawn as quickly and comfortably as possible, a ride-on mower with battery drive is just the thing for you.
The battery-powered ride-on mower is still rather rare. The first models have only recently been introduced as a competitor to petrol-powered tractor mowers.
Unfortunately, battery-powered versions are many times more expensive than the petrol-powered competition.
Nevertheless, the battery-powered ride-on lawnmower has its very own appeal, because as a child, who didn't always envy the grown-ups who raced across the meadow with their lawnmowing tractor? And the lawn is even shortened during the fun.
The ride-on lawnmower becomes a worthwhile gardening tool from an area of 500m². However, it is not only the pure area that counts.
The more corners and edges the small lawn tractor has to go around, the more awkward it becomes to use and its usefulness and fun factor sink into the bottomless pit.
Due to the area of use, the ride-on lawnmower with battery drive specialises in large green areas and, depending on the cutting width, reaches approx. 2000m² in 75 minutes with a single battery charge.
Like all battery-powered mowers, the ride-on version comes away with no emissions and is very quiet compared to the competition.
Buying criteria: You can use these factors to compare and evaluate battery lawn mowers
Finding the right cordless lawn mower is not easy. We have listed a few factors that should play a role in your decision. So consider which mower is right for you and think about it before you buy.
Important factors are:
- Battery type & capacity
- Charging time
- Engine power
- Weight & dimensions
- Cutting width & cutting height adjustment
- Additional functions & scope of delivery
It is very difficult to find the perfect mower that can do everything. Therefore, you should consider which criteria are most important to you.
Battery type & capacity
Although most cordless mowers today are equipped with a lithium-ion battery, you should also pay attention to this. As mentioned above, these batteries are particularly long-lasting and ensure that you have a lot of fun with your battery-powered mower.
It is best to find out what a replacement battery will cost you before you buy. Then you know what costs you might have to pay when your battery is worn out.
Battery capacity is also a fundamental factor that can make the difference between heaven and hell when using a battery-powered lawnmower.
If your battery dies every time you mow 3/4 of the lawn and you have to charge the battery, it will cost you a lot of time. Because then you have to wait each time until your battery is charged again.
Depending on the equipment, the same battery capacity can deliver different performance. For example, a push mower with the same mAh capacity can mow a larger area than a mower with a wheel drive, because the wheel drive is also driven by the electric motor.
The cutting technology also plays a role. Both whether one or two cutting blades are operated and the engine power are included in the power consumption.
If you do not have an additional battery for your lawn mower, the charging time is an aspect you should take into account in your decision. Often, there are additional quick chargers that speed up the charging process considerably and get your mower back into operation more quickly.
Nevertheless, charging time is a point that should not be given too much attention for the ordinary user. You should make sure to buy a lawn mower that can cover the area in one go or that has a replaceable battery.
However, if you are a gardener and often use the mower in quick succession, the charging time may also be an important aspect for you.
The engine power of the electric motor affects the cutting quality of your mower. If you choose a smaller motor, you must also expect that your mower will quickly reach its limits when mowing for longer periods of time, especially on wet lawns.
The higher the power, the smoother the blade will cut through the mass of green cuttings. Also make sure that the engine power is adapted to your cutting width.
A mower with the same engine power but a small cutting area will naturally need less power than its big brother.
On the other hand, the engine power usually has no influence on the speed of your lawn mower, as this is standardised to a walking speed of about 3 km/h.
Weight & dimensions
Especially for mowers without wheel drive, weight is a key aspect. Remember that you will have to push your lawn mower over the entire area without the help of an engine.
Fortunately, battery-powered mowers are lighter anyway. However, the weight increases with the battery capacity and selected additional functions.
Last but not least, it is important to adapt the choice of mower to the area to be mowed. In this way, you avoid carrying unnecessary weight or consuming more power than necessary.
The dimensions of a mower are not irrelevant either, as they are usually stored in the garden shed or cellar. Many mowers offer the option of folding the boom to such an extent that the space required can be significantly reduced. Furthermore, smaller mowers are more manoeuvrable and easier to handle.
Cutting width & cutting height adjustment
The cutting width determines the efficiency of your mower. Naturally, you can cut more area with a larger cutting width than with a narrower mower.
This makes the time-area ratio much more attractive. This is referred to as a shorter mowing time. However, with a larger cutting area the mower also becomes larger and more unwieldy overall.
|Lawn area||Cutting width|
|Less than 100 m²||up to 30 cm|
|100 to 500 m²||30 to 40 cm|
|More than 500 m²||Over 40 cm|
So the motto "the bigger, the better" does not always apply. As in many other cases, you should adjust the cutting width to your lawn.
Depending on how short you want to cut your lawn, you must also pay attention to the cutting setting of your mower. In addition to the minimum and maximum height, mowers also differ in the levels you can set.
Everything is possible, from three to ten steps. The cutting height usually ranges from 3 cm to 10 cm. This allows you to individually adjust the cutting height to the quality and type of your lawn and achieve the best results.
Weather conditions and hot spells are also factors that influence the optimum cutting height. A height adjustment with several steps ensures that you can adjust the lawn length perfectly.
In addition, the cutting height adjustment differs in the ease of adjustment. For some mowers, you have to take out the screwdriver and tinker with the mower deck yourself. On some, on the other hand, the height can be adjusted via a snap-in switch.
Let's think about the neighbour. As already explained, battery-powered lawn mowers are much quieter than their petrol-powered competitors.
But even among the cordless mowers, there are louder or quieter models, depending on the engine power and equipment variant. In general, however, the noise level does not differ that much, so there are much more meaningful arguments for choosing a mower.
Additional functions & scope of delivery
The range of possible additional functions for lawn mowers is larger than you might think.
Some lawn mowers have their cutting mechanism in the centre, across the entire width or on the edge. Depending on where the blade is located, it may be easier or impossible to cut close to the edge of the lawn. In the worst case, this would require another garden tool to trim the edges as well.
The scope of delivery varies greatly from product to product. Sometimes not even a charging cable is included. In most cases, at least the charging cable and battery are included in the package.
Complete packages that include additional batteries or particularly fast chargers are especially worthwhile. These are often cheaper in packages than if you buy the same accessories separately.
A catch box is not always included in the package either. So if you don't want to spread the mown lawn on the lawn again, you have to reckon with additional costs here, too.
Design plays a major role in many products. Whether this is the case with your lawn mower is something you can decide for yourself. Unfortunately, lawn mowers often do not come with the option of choosing the colour yourself.
The models are therefore only available in one design. The different versions of a model series also differ little in terms of design.
If design is considered to be of such great importance to you, you would have to disregard all technical aspects. And this should not be the goal of a lawn mower purchase.
So when it comes to design, you should at least turn a blind eye, maybe even two. In any case, your mower will probably spend all but 2 hours a week in the garden shed or in your cellar. So why waste so much thought on the design?
Facts worth knowing about the cordless lawn mower
Want to learn more about cordless lawn mowers? Then you should definitely take a look at the following sections. There we have compiled interesting information for you on the subject of battery lawn mowers.
Why and since when have cordless lawn mowers existed?
Rechargeable lawn mowers were developed to create a compromise between electric and petrol lawn mowers.
While the problem with the environment is perceived and accepted, at the same time the flexibility of a petrol lawn mower, because of the omission of the cable, is ensured by the fact that the electric motor is now powered by a built-in rechargeable battery.
Did you know that the first model of lawn mower was invented by Edwin Beard Budding in 1830?
Budding observed the principle of a cutting machine from a weaving mill and transferred the concept of a fixed blade with a rotating spindle to enable a machine to cut blades of grass precisely.
Although the technology to operate lawn mowers via rechargeable batteries has been around for a long time, it was ridiculed for a long time. Battery-powered lawn mowers were simply inferior to petrol lawn mowers in too many aspects.
Now that Tesla is even starting to run cars on batteries, electric motors have reached a level where they can compete with petrol lawnmowers.
Where does the battery lawnmower lag behind the petrol lawnmower?
Although a higher number of revolutions of the cutting blades usually ensures a cleaner and more precise cut, the penetrating power of an electric motor is still inferior to that of a petrol engine.
If the grass is too tall or wet, some cordless lawnmowers reach their limits and refuse to cut the green stalks a head shorter. This makes regular lawn mowing indispensable.
Furthermore, you can "recharge" your petrol lawnmower with a canister of fuel within a few minutes. Depending on the battery capacity, this process can sometimes take up to 24 hours. It is therefore all the more important to adapt the battery capacity to your lawn area.
What are the batteries made of?
Nowadays, battery-powered lawnmowers are usually equipped with lithium-ion batteries, which are also used in smartphones or tablets.
These are particularly light, quick to charge and powerful at the same time. An additional advantage of lithium-ion technology is that the batteries hardly discharge when you are not using them.
At the same time, using a battery that is not fully charged will not affect the life of the lawnmower in the long term.
Whereas not so long ago, due to limited charging capacity, cordless mowers were still recommended for rather small areas, some manufacturers now even state a range of well over 500m².
What is the service life of a cordless lawn mower?
One characteristic of rechargeable batteries based on chemical reactions is that they wear out. This means that their lifespan is not infinite.
Did you know that the batteries of a cordless lawnmower are very sensitive to cold?
It can happen that the batteries can no longer retain their full power or even break down completely once they are really cold. Therefore, they should ideally be stored at 15°C or removed after the last mowing.
So with time and use, these batteries lose power and performance. This can cause the battery to run down faster than usual. Some manufacturers even limit the durability of the battery to about 1000 charging cycles.
However, if your battery should break, you can get a new one from most suppliers for around €100. This is especially worthwhile for more expensive models.
