Greenworks Cordless Garden Tools: A Buying Guide for Spring

When you buy Greenworks cordless garden tools, you are really choosing a battery platform. Greenworks batteries only swap between tools of the same voltage, so pick 24V for a small garden and lighter jobs, 40V for most typical lawns and heavier tools, then buy one kit with a battery and charger and add cheaper tool-only models over time.

This guide explains the Greenworks platforms sold in the UK and US, how battery capacity affects runtime, what the warranties cover, and how to keep the cost down. Prices and ranges were checked in September 2026 and change often, so always confirm on the official site before you buy.

Why the battery platform matters most

Greenworks sorts its cordless range by voltage. Its UK voltage comparison page is clear about compatibility: you can use a battery from one 40V tool in another 40V tool, but you cannot use a 24V or 80V battery in a 40V tool. Batteries only swap within the same voltage.

That means your first purchase decides the rest. Choose one platform, buy one or two batteries, and then buy later tools "tool-only" without a battery or charger. Batteries and chargers are a large share of the cost of any cordless kit, so this is where the real savings come from.

It also means switching later is expensive. If you start on 24V and move to 40V in two years, your old batteries and charger will not work with the new tools. A little planning now avoids paying twice.

Which Greenworks platforms can you buy?

Which platforms you can buy depends on where you live. The UK site focuses on 24V and 40V. The US site lists 24V, 40V, 60V and 80V batteries, and Greenworks' global brand site describes its 24V, 40V and 80V platforms as powering more than 75 different tools.

One point worth knowing: the UK page lists power tools and vacuums on 24V but not on 40V. If you also want a drill or a car vacuum on the same batteries, 24V may suit you better.

What is Greenworks PowerAll?

PowerAll is the name Greenworks now uses for its 24V system in the UK and Europe. According to its PowerAll range page, the platform covers lawn and garden tools, home and garage power tools and lifestyle products such as camping kit, with more than 200 compatible products. Some heavier tools combine two 24V batteries to run at 48V.

Newer PowerAll batteries have a USB-C port that works both ways: you can charge the battery with a USB-C charger or use it as a power bank for a phone or laptop. Greenworks says its 140W USB-C charger fully charges a 4Ah battery in about 58 minutes. If you are mixing older 24V batteries with newer PowerAll ones, check compatibility on the product page before you buy.

Which Greenworks voltage should you choose?

Small gardens and patios: 24V

For a small lawn, a few borders and a patio, 24V is usually plenty. The tools are lighter, which makes a real difference when you are holding a trimmer at arm's length or carrying a blower round the side of the house. You can also share batteries with power tools, which is handy if you do DIY.

Medium lawns and mixed jobs: 40V

For a typical suburban lawn plus hedges, 40V is the sensible middle ground. It covers mowers, hedge trimmers, grass trimmers, blowers and chainsaws on one battery type, and the UK site quotes slightly longer runtimes than 24V.

Large plots: consider higher voltage or spare batteries

If you have a big lawn or regularly cut up fallen branches, the higher-voltage ranges exist for that in the US. In the UK, the practical answer for a larger garden is usually 40V with a second high-capacity battery so you can swap mid-job.

What does Ah mean on a Greenworks battery?

Voltage decides compatibility and power. Ampere-hours (Ah) decide how long a battery lasts. Greenworks' US battery page explains that batteries of the same voltage differ by their Ah rating, and a higher Ah rating gives more runtime. Common sizes include 2Ah, 4Ah and 5Ah, with larger packs on some platforms.

Some practical rules:

• Mowers drain batteries fastest, so give them your biggest battery.
• Trimmers and hedge cutters run happily on smaller, lighter packs.
• Two medium batteries can beat one large one, because you can charge one while using the other.
• Runtime claims are best-case figures. Long, damp or thick grass and higher power settings cut runtime noticeably.

How much do Greenworks cordless tools cost?

Prices change often and Greenworks runs frequent promotions, so treat these as a snapshot. At the time of writing (September 2026), the Greenworks UK website listed these examples:

Many of these were shown with higher "was" prices, which is a reminder that the brand discounts regularly. If a price is not reduced when you look, it may well be within a few weeks.

Worked example: kit plus tool-only vs three kits

Say you want a mower, a hedge trimmer and a grass trimmer on 40V. Using the UK prices above:

• Mower kit with two 2Ah batteries and charger: £259.99
• Hedge trimmer, tool only: £74.99
• Grass trimmer, tool only: £84.99
• Total: £419.97 for three tools, two batteries and one charger.

Compare that with the mower kit's tool-only price of £169.99. The difference of £90 is effectively what you pay for two batteries and a charger in the kit, which is less than buying a 2Ah battery (£78.99) plus a charger separately. That is why starting with a kit, then going tool-only, usually wins.

If you then add a 15% discount code on the two tool-only items (£159.98), you would save about £24, bringing the total to roughly £396. Codes often exclude items already on sale, so check the terms. Our guide to coupon stacking explains when codes and sale prices combine.

How to buy Greenworks tools: step by step

1. List every garden job you do in a year. Mowing, edging, hedges, leaves, pruning, patio cleaning and any DIY.
2. Measure your lawn roughly. Pacing it out is enough to judge whether one battery will cover a full cut.
3. Pick one voltage that covers all of them. Check the tool list for that platform on your country's Greenworks site.
4. Buy your most battery-hungry tool as a kit. Usually that is the mower.
5. Add other tools as tool-only. Buy them when they are on offer rather than all at once.
6. Buy from Greenworks or an approved reseller. The UK warranty applies to products bought through approved channels.
7. Register every tool and battery on the day you open it and keep your receipt.
8. Check codes and cashback before paying. Visit the Greenworks store page on CouponsBeast and our latest coupons.

What does the Greenworks warranty cover?

Warranty terms differ by region, so read the right page for where you live.

The Greenworks UK warranty page covers defects in materials and workmanship, excludes consumables such as blades and cords, and requires you to buy from Greenworks or an approved reseller. Claims start with the seller and proof of purchase. The US warranty requires product registration and applies to products built for sale in the US.

In the UK, the manufacturer's warranty sits on top of your legal rights. Under the Consumer Rights Act 2015, goods from a retailer must be of satisfactory quality and last a reasonable time, so contact the retailer first if a tool fails early.

Are Greenworks cordless garden tools worth it compared with petrol or corded?

Cordless tools are not the right answer for every garden, so it helps to compare the three main options honestly before you commit to a battery platform.

For most UK gardens, cordless hits the sweet spot. You avoid the trip hazard and cable management of corded tools, and you skip the fuel, servicing and noise of petrol. The trade-off is battery cost and runtime, which the platform approach in this guide is designed to manage.

A corded mower can still be the cheapest choice if your lawn is small and close to the house. And if you already own a cordless drill from another brand, check whether that brand has a garden range before committing to a second battery system.

Common mistakes when buying cordless garden tools

• Mixing voltages. Buying a 24V trimmer and a 40V mower means two sets of batteries and chargers.
• Buying every tool as a kit. You end up with a drawer of chargers and batteries you did not need.
• Underbuying battery capacity for the mower. A 2Ah battery may not finish a medium lawn, forcing a mid-cut recharge.
• Trusting the runtime claim. Real-world runtime drops with long or wet grass.
• Buying from unauthorised sellers. Grey imports may not carry the UK warranty, and cheap unbranded batteries can be unsafe.
• Forgetting to register. In the US it is a condition of warranty; in the UK it can extend cover.
• Storing batteries in a cold shed. Winter temperatures can shorten battery life.

How to pay less for Greenworks tools

1. Buy one kit, then go tool-only. Bare tools cost noticeably less than kits, as the worked example shows.
2. Stick to one voltage. Mixing platforms means buying multiple chargers and batteries.
3. Time your purchase. Spring bank holidays bring garden promotions, and our Easter sales guide covers the first of them. Late summer and autumn clearance, and Black Friday, can be cheaper still for next season.
4. Look for bundle deals. A mower and trimmer bundle with two batteries can beat buying separately, but only if you need both.
5. Use a welcome code if you are new. See our guide to first order discount codes if you are buying direct for the first time.
6. Consider refurbished carefully. In the US, Greenworks Renewed products carry a much shorter 90-day warranty, so weigh the saving against the cover.

How to look after Greenworks batteries

Batteries are the priciest part of the system, so treat them well. Always follow the storage guidance in your manual, but these general habits help most lithium-ion garden batteries last longer:

• Store batteries indoors in a cool, dry place over winter, not in a freezing shed or hot garage.
• Avoid leaving them completely flat for months; a partial charge is better for long storage.
• Let a hot battery cool down before charging it after heavy use.
• Keep contacts clean and dry, and never use a battery that is cracked, swollen or leaking.
• Only use Greenworks chargers designed for that voltage.

A battery that lasts an extra season or two is money saved, especially when replacement packs can cost as much as a tool.

Tips for choosing your first Greenworks tools

• Start with the tool you use most, usually the mower, and buy it as a kit.
• Pick the lightest tool that does the job for anything you hold at arm's length.
• Buy a second battery before a third tool if runtime is your main complaint.
• Keep receipts and registration confirmations together in one email folder.
• Compare prices across retailers and check the Greenworks store page before you pay.
• Autumn is a good time to buy for next spring, as retailers clear garden stock.

Bottom line

The best way to buy Greenworks cordless garden tools is to choose one voltage that covers every job in your garden, buy one kit with a battery and charger, then add tool-only models as they come on offer. For most UK gardens that means 24V (PowerAll) for small spaces and DIY, or 40V for a typical lawn with hedges. Register everything, look after your batteries and check for codes before you pay, and your system will stay cheaper to run and expand for years.
