There are now a range of options beyond the traditional petrol and electric lawn mowers, as cordless and robotic lawn mowers becoming increasingly popular.

These battery-powered lawn mowers are lightweight, quiet and produce zero emissions — unlike petrol lawn mowers.

Getting the best cordless lawn mower for you means ensuring it is the correct size, weight and cuts to the length you need. This has to be balanced alongside its cost and the battery life.

Because of the sheer quantity of lawn mowers on the market, our experts have trialled and tested a range of brands to make certain you find a cordless lawn mower that meets your criteria.

In this article, we review the best cordless lawn mowers and clearly outline the pros and cons of each one.

What are the benefits of a cordless lawn mower?

There are a variety of benefits to buying a cordless lawn mower in comparison to the more traditional petrol or electric models.

These benefits include:

  • Easy to manoeuvre: Without a cord, cordless lawn mowers are typically easy to manoeuvre. Most cordless mowers are lightweight, too, because there are fewer moving parts compared to a petrol mower.
  • Quiet: Cordless lawn mowers are powered by a lithium-ion battery making them much quieter than petrol-engine mowers.
  • No emissions: The lack of an engine means cordless lawn mowers do not emit emissions.
  • Minimal maintenance: Cordless lawn mowers do not need regular servicing like petrol mowers do.

How to choose the best cordless lawn mower

Your budget and the size of your lawn will be pivotal in deciding which brand and model of cordless lawn mower will best suit your needs.

For example, if your garden is small, a short battery life may not be such a concern because you are unlikely to be mowing for long.

When mowing a big open space, you need the reassurance that your lawn mower will not run out of charge. If it does die, a quick charge time will ensure you can finish the job promptly.

Here are some key areas to consider when purchasing a new cordless lawn mower.

Price ranges for cordless lawn mowers

Cordless lawn mowers can quickly become expensive. A substantial amount of the cost is down to the battery.

The battery is lightweight, compact and will charge up quickly. These batteries should hold charge, too, and not lose power in storage.

For an entry-level cordless lawn mower, you can expect to pay between £200 and £350. A mid-range mower will cost £400-£550 and a premium machine’s price can be up to £950.

While most cordless lawn mowers are sold in a bundle including the battery and charger, this is not always the case. This should be checked alongside the length of the warranty, which can be different for the battery and lawn mower body.

Cordless lawn mowers batteries

The power source in a cordless lawn mower is a small, rechargeable lithium-ion battery.

The power of the batteries can vary from 36 volts up to a huge 80 volts. This determines the cutting power and runtime on a single charge.

Many manufacturers ensure that the battery can be used in other tools they produce. On some premium models, you can use two batteries in tandem allowing you to mow for longer.

How long do cordless lawn mower batteries last?

How long the battery lasts on a single charge depends on the model. Some cordless lawn mowers have an eco or power saving mode to extend the battery life.

A battery can take anywhere from 60 minutes to over two hours to charge. Lithium-ion batteries can be used when partly charged if you are in a rush.

Some brands have faster chargers cutting the waiting time down to 30 minutes, but these often have to be bought separately.

A cordless lawn mower battery will typically last between three and five years (or 500 charges) before needing replacing.

Cordless lawn mower sizes

The size of any cordless lawn mower you buy must match the size of your lawn.

A wide cutting width will save you time on a large area. On a small lawn, a low battery power may well suffice.

The size of a grass collector on a cordless lawn mower also varies. Capacity can range from 30 to 70 litres. This will impact how often you need to stop and empty the bag or box.

You will also need to consider the weight of a full collection bag, particularly if mobility is a concern.

Hand-propelled vs self-propelled cordless lawn mowers

You will also want to consider whether you want a hand-propelled or self-propelled lawn mower.

A hand-propelled model is one pushed and steered by the user and will not provide mechanical assistance.

If you have a large or sloping lawn, a self-propelled lawn mower could make the task easier.

Pros:

  • Easy to assemble
  • Easy to use
  • Motorised back wheels
  • Excellent cut

Cons:

  • Size makes it hard to store
  • Heavy

This mower is a dream to use. Not only does it have a safe but simple bar and push-to-start button, but it also has motorised back wheels, to help you push it across the lawn and cut as efficiently as possible. It gives a great uniform cut, even on uphill or uneven ground. Combining a traditional design in British racing green with a modern cordless battery, it’s great for whizzing around big country lawns. However, some may find this a heavy machine to push, even with the motorised wheels. This same bulkiness also makes it a little tricky to store.
