What Makes A Good Cordless Mower?If you are reading this then there is a good chance that you have already decided to invest in a cordless lawn mower and are aware of the many benefits of these tools. But that doesn’t mean that you are comfortable with choosing a good cordless mower or knowing the right type for your lawn. If you feel a little overwhelmed at the choice, you’re not alone.

Familiarising yourself with the features of a cordless mower and which ones will benefit your needs is an important part of purchasing this type of equipment. In this guide, I’ll be sharing everything you need to know to help you make the most informed choice.

How Much Should I Pay For A Cordless Mower?

The problem that a lot of people face when choosing a cordless lawn mower is that they often end up paying quite a bit more than they expected, especially if they’re moving over from a petrol mower. You see, since corded electric mowers are so affordable, many assume the same will be true of a cordless model.

Now, I’m not telling you that you’ve got to spend your life savings here, because you can pick up a decent battery-powered mower for under £200. On the flip side, there are models that retail in excess of £1000; it all depends on what you’re looking for and the needs of your garden as to what will be most appropriate. I’m also assuming that you have a budget in mind, so you should try and get the best mower you can within this.

If you have a smaller garden, the chances are that you won’t need to spend quite as much because you aren’t going to need something with as high voltage or Ah. On the other hand, if you have a large lawn then you’ll end up spending a little more as you’ll need bigger and more powerful batteries with a much longer running time.

In terms of garden size, you’ll also need to consider the cutting width of the mower. The larger your lawn, the bigger this cutting width needs to be but of course, this means a bigger mower with a greater cost. For the smallest lawns, you could get away with a 32-33cm blade mower, but if your garden is more on the medium side then I’d suggest going for something around 38cm. There are people with huge lawns and in this case, you’ll need to opt for something bigger than 40cm. There are some massive ones out there like the Husqvarna LC 551IV that has a whopping 51cm deck; but it does cost more than a grand, so I’d really only suggest tools like this if you actually need them!

Lawn Sizes to Lawn Mower Deck Guide

Size of lawnSquare metres (Square Feet)Deck Size
Small lawnLess than 200m² (2200 Sq. Ft.)30cm to 34cm (12" to 14")
Medium lawn200m² to 350m² (2200 to 3800 Sq. Ft.)34cm to 40cm (14" to 16")
Large lawn350m² + (3800 Sq. Ft. +)Over 40cm (Over 16")

Another thing that may affect the price of the mower is whether or not it is self-propelled. This used to be something that you’d only see in petrol models but more and more cordless manufacturers are getting on board with this and for people with larger gardens or who might not be as physically fit, it’s a lifesaver! Self-propelled cordless mowers essentially move themselves, all you need to do is steer, but this technology comes at a cost, so it is worth thinking about whether you really need it or not.

What Features Should A Good Cordless Mower Have?

What Features Should A Good Cordless Mower Have?The beauty of the modern lawn mower is that it comes with so many features that maintaining an aesthetically pleasing garden has never been easier. Of course, you don’t have to go for all these add-ons, choosing a basic mower that does nothing more than cut the grass is ideal if you want something simple and easy to use.

As I discussed above, the cost of the mower will rise with certain functions and additional features will boost the cost. While there are features that you might expect to see on any decent mower, they might not all be included on any given model. But then again, you might not need them all, so do think about what you’re trying to achieve and the needs of your lawn before spending hundreds of pounds on an all-singing all-dancing mower with features that you’ll never use. Similarly, don’t be tempted to try and save money by cutting out features that you desperately need.

Some of the things that you would commonly expect to see on a standard model are:

  • Foldable handles that reduce the overall size of the mower for easier storage. The handles may also be height adjustable making it easier to find a comfortable mowing position according to your stature. Also look at the design and padding of the handles to ensure comfort and reduced vibrations.
  • A rear roller which allows you to create a striped effect for a more formal looking lawn.
  • A mulching plug which can be inserted when you don’t want to collect the grass clippings. Instead, they are diced up in the mower’s deck before being deposited back into the lawn to act as a natural fertiliser. Some mowers may also have a side or rear discharge chute as alternative ways of discarding the lawn clippings. The more mowing functions you have, the more likely it is that the price will increase.
  • A good range of cutting heights is important on any mower and cordless models are no exception. Having the ability to cut the lawn to different heights means that you can better care for your lawn over the seasons and cutting in different conditions will be easier. You’ll also want to check how easy it is to change the cutting height; the best cordless lawn mowers have a simple single lever in the centre of the mower that allows you to quickly and seamlessly move through the various heights.
  • Safety whilst mowing and also when your mower is stored is imperative especially around young children, so it’s important to look for a mower that has good safety features. The most common thing you’ll find is a safety key which must be inserted in order for the mower to work and can prevent accidental start ups.

A Note About Lawn Mower Build Quality

A Note About Lawn Mower Build QualityWhile the things I have discussed above are in relation to the capabilities of the cordless lawn mower, it is also important to think about how durable and well-made the tool is. The last thing you want is a lawn mower that is going to crack, rust or fall apart after one season.

Lawn mowers are generally made with either a plastic (poly) or steel deck. The latter always comes at a higher cost, but in terms of durability, is unrivalled. That said, you should keep in mind that steel mowers are much heavier and so may be more difficult for some users to handle and move around.

Weight is an important factor to consider as even if you wouldn’t struggle moving it around the lawn, you might find it tricky getting it to and from the shed if you need to carry it. If you’re going to go for a very heavy mower, then I’d recommend considering a self-propelled one. That said, cordless mowers aren’t anywhere near as heavy as their petrol cousins and once you take the battery out, they’re pretty easy to lift.

At the end of all of my mower reviews I encourage users to share their long term experience of their mower in terms of build quality, access to spare parts and customer service. I also provide updates if I experience any issues with build quality when using the mowers I have purchased over a period of time, so this section is worth checking out.

Cordless Lawn Mower Batteries And Chargers

The thing that sets the cordless mower apart from the crowd is the way that it is powered. Rather than using petrol or a mains connection, these tools run on a battery, usually lithium-ion.

In the past, when you have chosen batteries for anything, you may not have put much thought into it but when choosing a cordless mower, the battery is one of the first things you should be looking at. The best mowers will come with a powerful battery that doesn’t flake as the charge runs out and lasts long enough for you to get the job done.

Battery Voltage

Battery voltage refers to the potential the battery has to push current through it. The higher the voltage, the greater capacity the battery has to take on more challenging work, essentially making it more powerful. You’ll generally find that cordless mowers are 18v or 20v, but there are examples outside of this.

For larger lawns or those that are a little more demanding in terms of grass density and terrain, you may be better opting for a more powerful battery.

Battery Run Time

Cordless Lawn Mower Batteries And ChargersOnce again I must go back to talking about the size of your lawn. If you have a huge lawn then a battery with a 20 minute running time simply isn’t going to cut it, unless of course you have multiple batteries to utilise. Shorter running times, however are likely to be ideal for a small patch of lawn.

Generally speaking, your cordless mower will have a running time between 30 and 45 minutes but this will vary massively by model. You must also take into consideration the cutting conditions. If your mower is having to work harder through long grass, for example, then this is going to drain power more quickly than if you were giving a well-manicured lawn its weekly trim. Bearing in mind that some cordless mowers will come with two battery slots, whereby it will either jointly use both batteries or alternatively switch to the other battery when one has depleted.

You can tell the running time of a battery by its Ah number. You’ll normally find that this is anywhere between 2.0Ah and 6.0Ah for cordless mowers, but much like everything else, there is room for exceptions. The higher the Ah number, the longer the battery will run on a single charge and needless to say will cost significantly more.

It’s also worth considering the running time in comparison with the voltage and whether there are options to use different batteries. Some manufacturers will sell cordless mowers with the options of either an 18v or 20v battery or options to choose between 2.0, 4.0 or 5.0Ah, for example. This allows you to tailor the tool to your specific needs.

Power Sharing And Additional Batteries

One of the best things about cordless tools is that many manufacturers use a power sharing system. This means that the battery that comes with your mower can be used across a wider range of tools, provided they are compatible with the battery voltage.

If you prefer a certain manufacturer and already have a lot of cordless tools, this is great as you may be able to buy your mower as a bare tool, which will save you money.

However, you want to be sure that there is also an option to buy additional batteries in the event that yours gives up the ghost. For this reason, it is important to first research how easy it is to get your hands on replacement batteries and how much they are. It it worth noting that the batteries are normally just as expensive as the cordless mower, sometimes even more.

Dual and Fast Chargers

Being able to charge your mower battery quickly and easily is one of the most essential features of these tools. This is especially true if you find yourself running out of juice before the job is done. The good news is that a lot of mowers come with a fast charger, which can cut the charging time in half. Usually, this is slightly more expensive but worth it for the convenience.

Moreover, if your mower runs on two batteries or comes with two batteries, then you’ll want to be able to charge them at the same time which is where a dual charger is invaluable.

Battery Ease Of Use

While you might think that using a battery is one of the more simple parts of owning a cordless mower, there are some models that make life more difficult. You should consider how easy it is to take the batteries in and out of the mower, and how many can be put in at once. There are some models that will hold two batteries despite only taking power from one at a time. This means that, when the first battery drains, the power is then taken from the second battery, saving you the hassle of stopping in the middle of the mow.

But you also want to find out how easy it is to see how much charge is left. Many of the best cordless mowers come with a battery gauge on the handles as well as on the battery itself, that tells you how much run time is left. This is great for preventing any surprises halfway through tending to your garden.

Knowing Your Cordless Lawn Mower Brands

Knowing Your Lawn Mower BrandsThere are so many brands that make cordless mowers; Bosch, Black and Decker, GTech, Husqvarna, Hyundai, EGO, Greenworks, Hayter and so many more. This can be daunting especially if you have never used any of these brands before. It’s good to educate yourself on the reputation of any given brand and be sure that you will be getting something that is excellent quality and will do everything you expect it to.

You should make it a priority to look into the customer service available from your chosen brand and ensure that, in the event of any problems, you are able to easily speak to an advisor and get a solution. Is it easy to get replacement parts, for example? Or is there a dedicated service line for customers, if so, what are the opening hours? Don’t just presume that the quality of a premium brand is naturally going to be superior compared to that of a lesser brand. Whilst this might have been true some years ago, many of today’s cordless mower components are made in China and assembled in the home country.

I’d massively suggest looking at the warranty on the mower as well, but keep in mind that the warranty on the battery may be significantly shorter than the warranty for the mower itself. Some of the best warranties are provided brands such as EGO (5 years on mowers and 3 years on the battery).


A cordless lawn mower is a great way to maintain your lawn without the restrictions of movement associated with a corded mower and without the maintenance and fumes that you get from a petrol mower. But since there are so many models out there, it can quickly get confusing when trying to choose the right one for you.

My rundown of everything you need to know about cordless mowers will help you make the right choice for your lawn, your budget and you.
