Cordless Hedge Trimmers Compared: 9 Models by Battery, Blade and Weight

As an Amazon Associate we earn from qualifying purchases. Details

A cordless hedge trimmer cuts a hedge or shrub without a cord, so you can work anywhere you can reach with a battery. The main choice is not the trimmer itself but the battery it runs on, because most listings in this group are sold as tool only. Most people buy a hedge trimmer once a year, so the choice should fit the battery and the hedge you already have. This guide compares nine cordless hedge trimmers using the battery, blade, weight and warranty figures each listing states, so you can match a trimmer to the battery you already own.

Quick answer

Start with the battery you already have. Several listings name a battery platform in the title, such as DeWalt 20V, Milwaukee 18V or Greenworks 40V, and most are tool only, so you will need to buy a battery and charger separately unless the listing says otherwise. Then choose the blade length for the hedge you plan to cut, and check the weight if you hold the trimmer for long periods. The picks below show each listing’s own figures.

At a glance: the 9 picks, by their own spec fields

Pick	Blade / weight	Battery platform	Flag
Cordless Hedge Trimmer for DeWalt 20V (HP-02ALJ2)	1.8 lb; blade length not stated	DeWalt 20V MAX (battery not included)	Not a Cobra or Gtech product

2-in-1 Hedge Trimmer 7.2V Mini Shears	6 in blade	Built-in 7.2V (up to 60 min runtime)	Not a Cobra or Gtech product
Greenworks 40V 24″ Hedge Trimmer	8.4 lb, 24 in blade (heaviest here)	Greenworks 40V (tool only)	Not a Cobra or Gtech product
DURATECH 7.2V 3-in-1 with Extension Pole	1.3 lb; 50 in detachable pole	Built-in 7.2V	Not a Cobra or Gtech product

2-in-1 Cordless Hedge Trimmer, One-Handed (DC60102)	6.3 in blade	2.0Ah battery (runtime not stated)	Not a Cobra or Gtech product

None of these nine picks is the Cobra H5024V or the Gtech HT50 named in the page title — all are unrelated generic or other-brand cordless hedge trimmers. If you specifically want to compare the Cobra H5024V and Gtech HT50, search for those exact model listings on Amazon.

Battery first

A cordless trimmer is only as useful as its battery, and the battery platform decides which trimmers you can run. Several listings in this group name DeWalt 20V MAX batteries, and three of them are the same platform. The RKBUDOL listing names Milwaukee M18 batteries. The Greenworks listing is a 40V platform, with a lithium-ion battery of its own.

If you already own tools from one brand, look for a trimmer that matches that battery. Buying a trimmer on a different platform means buying a second battery and charger, which adds cost and carrying weight.

Tool only or with battery

Read the title and the bullets for the words tool only, battery not included, or battery sold separately. The HEINPRO, VERVEWAVE and 3D VO INN listings all say the battery and charger are not included. The RKBUDOL listing says the package includes only the main tool. The Fulljion listing is the exception in this group, because its bullets describe two batteries and a charger in the box.

Check this before you add the trimmer to your cart. A trimmer that looks like a bargain may need a battery that costs more than the trimmer itself.

Blade length and the hedge you cut

Blade length decides how much hedge the trimmer can cut in one pass. The RKBUDOL listing gives a blade length of 8 inches, and the sunchers and VCAN ACTIVE listings give 6 inches and 6.3 inches. The Fulljion listing gives 20 centimeters, which is about 7.9 inches, so convert before you compare with the inch figures.

A short blade suits small shrubs and trimming along a border. A longer blade works better for a tall hedge, but a longer blade also makes a heavier and harder-to-control tool. The Greenworks listing gives a 24-inch blade, which is the longest in this group, and its listing also includes a 1-inch cutting capacity.

Hedge trimmer or grass shear

Many listings in this group describe a 2-in-1 tool that works as a hedge trimmer and a grass shear. The VERVEWAVE listing says two blades switch between hedge and grass work. The DURATECH listing describes a quick-change blade system and a 50-inch detachable pole for the grass shear. The sunchers listing also describes switching between a hedge trimmer and a grass shear.

A 2-in-1 tool gives you more uses, but the switching takes time, and a grass shear is not a substitute for a dedicated hedge trimmer on a tall hedge. If your main job is hedges, choose a model whose primary function is the hedge blade.

Weight and balance

Weight matters more the longer you hold the trimmer. The HEINPRO listing gives a weight of 1.8 pounds, the DURATECH listing 1.3 pounds and the 3D VO INN listing 3 pounds. The VERVEWAVE listing gives 3.3 pounds and the Fulljion listing 3.6 pounds. The Greenworks listing gives 8.4 pounds and a 38.58-inch length, which is the heaviest and longest tool in this group.

Hold the trimmer at arm’s length for a minute before you buy it, if you can. A tool that feels fine for a minute may feel heavy after a long hedge job.

Trimming a hedge safely and evenly

Plan the cut before you start the trimmer. Walk along the hedge once without cutting, and mark the high spots and the low spots. Work from the bottom up on each side, so the top of the hedge is trimmed last, and keep the blade level rather than angling it into the hedge.

Cut in short passes, and let the blade reach full speed before you touch the hedge. A trimmer that stalls in thick growth can kick back, so back the blade out and cut again rather than forcing it. Keep the cord-free battery away from wet grass and mud when you change positions.

Clear the clippings as you go. Leaves and small branches under the hedge can hide a stone, a hose or a tool you could step on. Pick up the cuttings with a rake or a tarp, and keep the work area clear before you move to the next section.

Storing the battery and the trimmer

Store the trimmer and the battery in a dry place, away from direct heat. Charge the battery only with the charger made for it, and do not leave a battery on the charger after it is full. Check the blade for sap and debris after each job, and wipe the blade dry before you store it, so it does not rust.

Worked example: blade length in inches

Twenty centimeters is about 7.9 inches, so the Fulljion blade is about 0.1 inch shorter than the RKBUDOL blade. For practical purposes the two blades are close in length, so the choice between them depends on weight, battery platform and whether you need the 2-in-1 grass shear. The Fulljion weighs 3.6 pounds, and the RKBUDOL listing does not give a weight in its specs.

Convert every length to one unit before you compare. A blade listed in centimeters can look longer or shorter than an inch figure if you do not convert it.

Warranty and support

Warranty terms differ across this group. The Greenworks listing states a two-year warranty in its specs, and the Fulljion listing states an 18-month warranty. Several listings do not state a warranty in the specs, so check the product page or the seller before you buy.

A warranty is useful only if you keep the receipt and the model number. Record the model number when you buy the trimmer.

Safety on the job

Powered hedge trimmers are generally designed with safety devices so that they work only when both of the operator’s hands are on the handles. Use the two-handed grip the tool is designed for, and keep your hands and feet clear of the blade at all times.

A federal recall shows why the controls matter. CPSC recall 25-334, dated June 12, 2025, covered RYOBI 40V 24-inch cordless hedge trimmers, where the blade could activate after only one control was pressed. None of the nine picks in this guide is the recalled model, but the lesson applies to any trimmer: check the trigger and safety controls each time you use the tool, and follow the manual.

Matching the trimmer to your hedge

Measure the hedge before you choose the trimmer. Note its height and its width, and check the blade length against the width you need to cut in one pass. A narrow hedge can be trimmed with a short blade in a few passes, while a wide hedge is faster with a long blade, but a long blade is heavier to hold overhead.

If the hedge is tall, check whether you can reach the top from the ground. A trimmer with a pole or a long blade lets you reach higher without a ladder, and the 3-in-1 pole option in the DURATECH listing is built for that kind of reach. Do not use a ladder while holding a running trimmer; set the work up so you can keep both feet on firm ground.

Choosing for light or heavy use

A light trimmer suits a yearly trim of a few shrubs and borders. A heavier trimmer with a longer blade suits a hedge you cut several times a season. Think about how often you will use the tool, and choose the weight you can hold comfortably for the full job rather than the lightest model on the page.

Check the included items for heavy use. A second battery lets you keep working while the first one charges, and the Fulljion listing includes two batteries and a charger in its bullets. The other listings do not describe a second battery, so add one to your cart if the job is long.

Mistakes to avoid

Choosing by the title alone. Titles often list the battery voltage and the blade length in one line. Check the specs and the bullets for the blade length and the included items.

Ignoring the battery platform. A trimmer on a different battery platform means a second battery and charger. Check the platform before you buy.

Buying the longest blade without need. A long blade gives reach, but it also adds weight and makes the tool harder to control.

Skipping the weight check. A trimmer that feels light in the store may feel heavy after a long session.

Assuming a 2-in-1 tool replaces a hedge trimmer. A grass shear and a hedge trimmer do different jobs well, so match the tool to your main task.

FAQ

Is a cordless hedge trimmer as powerful as a gas model?

The listings in this group do not compare power with gas models, and they do not state a cutting power figure in the specs. Choose a trimmer by the blade length and the battery you need for the hedge you cut.

Do I need to buy a battery with the trimmer?

Often, yes. Several listings in this group are tool only, and the HEINPRO, VERVEWAVE and 3D VO INN listings say the battery and charger are not included. Check the bullets before you order.

Can I use one battery for several tools?

Only if the tools share the same battery platform. The listings name DeWalt 20V, Milwaukee 18V and Greenworks 40V platforms, and a battery from one platform does not fit another.

What blade length should I choose?

Choose a blade length that matches the hedge you cut. A short blade suits small shrubs, and a longer blade suits tall hedges. The listings in this group range from about 6 inches to 24 inches.

Are 2-in-1 trimmers good for hedges?

They can be, but a 2-in-1 tool switches between a hedge blade and a grass shear. If you cut hedges often, look for a model whose main job is the hedge blade.

How do I stay safe with a cordless hedge trimmer?

Hold the trimmer with both hands, keep the blade away from your body and your feet, and check the trigger and safety controls before each use. Follow the manual for the model you own.

Bottom line

For most owners, the right cordless hedge trimmer is the one that runs on the battery you already own, whose blade length fits the hedge you cut, and whose weight you can hold for the full job. Use the nine picks above to compare the listed figures, and confirm the battery and included items on the product page before you order.
