Over the last 17 years I have been running Fredshed I have tested around 25 cordless hedge trimmers.

Cordless hedge trimmers have significant safety and convenience advantages over 240v mains tools. By nature hedge-trimmers "take a lot of stick",  so need lots of power.

In the past this was hard to supply from the available technology, but now we have high capacity lithium ion batteries.

The increased power of these new batteries makes cordless hedge trimmers a viable alternative to mains powered and petrol hedge trimmers.

The smallest ones have 10.8v batteries and are only for small hedges and light work.

The 18v models will cut a medium size well kept hedge.

For thick stems and large hedges there are 36v (and higher) models but these start to get heavy.

Bosch AHS 50 -20 Li and 55-20 Li 18v Cordless Hedge Trimmers

This is the 2nd generation of this superb tool being tested on a thick hedge in my garden.

There are 2 models - 50 and 55cm long blades - so not much difference.

Both were developed from the first Bosch 18v Li-ion trimmer, the superb AHS 48 Li.

The new models have several improvements.

If you want a cordless hedge trimmer for thicker or less well kept hedges the new Bosch 18v models are lightweight but will cut stems up to 20mm thick. This is partly due to the Bosch anti-stall technology that reverses the blades in a nano second if the circuitry detects jamming. This not only saves time but also your fingers as trying to un-jam a sharp bladed hedge trimmer can be a dangerous process.

There are two 18v versions, both with incredibly light and powerful Li-ion batteries. The AHS 50-20 Li has a 50cm blade and weights a mere 2.5kg whilst the slightly longer bladed AHS 55-20 Li weighs 2.6kg. Both run for approx 40 minutes depending on the thickness of the hedge you are cutting. If you buy a spare battery then you can cut your hedge and have one on charge as you work, take a tea break and be ready to go again with a full charge!

One 2.5 amp hour battery can cut a lot of hedge. Recharge time is 1 hour. A spare 2. amp hour battery is best value at around 30 and can be used in a wide range of Bosch power tools.

Bosch give a genuine 2 year warranty on this hedge trimmer and you can extend this to 3 years for free by registering your purchase within 4 weeks on the MyBosch website. I don't know any other manufacturer with such a good warranty.

Bosch AHS 50-20 LI 18 V Hedge Cutter

Nothing beats this in the 18v category for weight and power due to the quality of the blades and the electronics that prevent it jamming.


We used this Bosch battery hedge trimmer on thick old ivy and was amazed how well it cut and how long the small battery lasted.

The Ryobi One + 18v hedge trimmer also did well in my test but was more prone to jamming on thicker stems as it does not have the patented anti-jam electronics of these new Bosch models.

In 2016  Bosch upgraded the battery in the 18v hedge trimmers to 2.5 amp hour. This battery can be used to power the blower seen below and several other Bosch tools including the new telescopic pole hedge trimmer. The only small criticism I can make of the Bosch AHS 50-20-Li and its sister is that the battery can be a little awkward to release for users with arthritic hands. On the plus side the blade cover is the easiest to get on and off and the trigger and safety lock easy to operate.

In 2018 a new chainsaw was added to the range too!

Makita 18v Cordless Hedge Trimmer

As a big fan of Makita 18v DIY tools I had to get this hedge trimmer. It is sold naked so I could use the batteries and charger that I have for my drill and chainsaw.

Tools made by Makita are top quality and the DUH523Z is no exception. However it is 1kg heavier than the Bosch 18v model and it does not have the anti-jam mechanism that makes that one so effective. The advantage it does have is that it can take larger capacity batteries which is ok if you are strong enough to hold it up in use. It has a 52cm long blade that is replaceable.

Keep your hedge trimmer blades running with special resin cleaner and lubricant


Hedge trimmer blades can be very badly affected by the build up of resin, especially from conifers.

The resin forms a hard layer that stops the blades moving freely which can then cause strain to the motor.

The German made Stihl product is unique in that it will remove resin AND lubricate in just a couple of sprays.

The 300ml can is designed for professionals who will use it daily so a can like this will last years in domestic use.

I also like the Bosch lubricant as it is pump action and not aerosol so there is less waste and mess. It is a very good lubricant but does not remove the resin like the more specialised Stihl product.

Latest and Lightest Long Reach Cordless Hedge Trimmer

After ordering the Gtech HT20 I was impressed by the fast delivery with text alert.

The tool was well packaged with good instructions in plain English. It is well made and easy to operate. I like the size, weight and design.

The 18v Li-ion battery has 4 lights to tell you its state of charge and is very easy to get in/out. This is the lightest and most effective long reach battery hedge trimmer I have tried in the last 16 years and everyone that has used it so far has been impressed.

You can buy longer, telescopic models from other brands but they are just too heavy for many people to use for more than a few minutes.

I think that Gtech have got the size and power just right with the new HT20.

Bosch 12v Model - For Smaller Hedges - or Smaller Users

This lightweight, cordless hedge trimmer uses a compact 12v Li-ion battery. The same battery is used in 20 other tools in the Bosch 12v Power For All range. Originally the batteries were described a 10.8v but are now 12v and the tools named "EasyHedgeCut" EasySaw, etc. The rebranded tools now use a new 2.5 amp hour battery that is twice as powerful as most similar looking batteries from other manufacturers.

The combined quality of the blade and anti-stall electronics it makes this small hedge trimmer punch well above its weight.

It is not as powerful as the Bosch 18v AHS 50-20Li which is my best recommended cordless hedge trimmer, but it is about 50 cheaper and ideal for smaller or well kept hedges. I am currently testing the small 12v grass trimmer that uses the same battery and it is one of the best tools I have tried this year. Like this little hedge trimmer it is ideal for small jobs and small gardens and is light enough that you don't need too much strength to use them. In fact I can use both of these tools from my wheelchair.

Heavy Duty Cordless Hedge Trimmers



Bosch AHS 54-20 LI Cordless 36 Volt Li-Ion Hedgecutter

This hedge trimmer was the first of a new breed of garden tools powered by high powered batteries designed to offer a serious alternative to mains electric and even petrol machinery.

Bosch made a head start in this with a range of all 5 garden tools that are powered by one, interchangeable 36v Lithium ion battery.

I have used this battery for 10 years in a mower and it is impressive. This new hedgetrimmer has the usual top quality Bosch blades and combined with a 36v battery it performs really well. When cutting my large bay tree it actually cut through branches I would usually have to use secateurs or loppers on!

With the battery fitted it is quite a heavy tool so this is not one for old ladies, feeble men and anyone a bit weak.

The tools comes with a small 1.3ah battery but 2 larger ones are available separately.

Best Large Cordless Hedge Trimmer? -Greenworks 40v Hedge Trimmer


The blade can be rotated 90 degrees for more comfort.

On a typical hedge the battery should give 30 minutes of cutting.

If you have a very large hedge you can buy a larger battery or a 2nd smaller battery.

I have tried many cordless hedge trimmers and this one has a great balance between power and weight.

I love the rotating blade for more comfortable use and the 61cm long blade.

It is similar to the Bosch 36v trimmer but easier to use and a bit cheaper.

Best Small 3.6v Battery Powered Topiary Shears

Bosch Isio Cordless Shrub/ Grass Shear

A new breakthrough in powered garden tools, this lightweight grass shear and shrub trimmer has Lithium Ion batteries for power and durability. The Bosch ISIO is similar to the Award winning Wolf trimmer but it is smaller, lighter and cheaper.

The latest version of this tool has a anti-jam electronics that stop and reverse the blades the instant it detects too much force. This new feature makes a lot of difference especially when the battery is running low as this is when any trimmer is more likely to get stuck on a thick stem.

Grass and Shrub Trimming!

The Bosch ISIO can be converted from a small shrub trimmer to a grass shear in seconds and is surprisingly efficient. Running time is very good thanks to the Li-ion batteries and I get 20 minutes use which included some woody shrub material. The softer the material you cut the longer the battery will last between re-charges.

Anti -Jam electronics helps stop the blade getting stuck. If too much resistance is detected the blade quickly reversers and has another go. For light trimming work on to box hedges and rockery shrubs I love these little single handed cordless trimmers.

Breaking News - Fredshed tests the Von Haus alternative to the Isio

VonHaus 7.2V  Shrub Trimmer

VonHaus 7.2V Lithium-Ion Cordless 2 in 1 Grass and Hedge Trimmer with bar and wheel plus charger

This bargain trimmer (orange & black) has all the features of the Isio but has a more powerful 7.2v battery.

The blade is also wider than the Isio and the switch more comfortable. It comes with the extension handle and shrub cutting blade.


Von Haus is a UK based company that specify gardening and DIY tools to be made for them in various factories in China. In fact Bosch do this as well, especially with their cheaper products and those stocked by the big DIY chains. Von Haus make a similar tool to the Isio that is much cheaper but also better in many respects.

 VON HAUS 7.2v Dual Purpose trimmer with handle included

The Von Haus trimmer has a 7.2v battery whilst Bosch only has 3.6v. This makes quite a difference in the time the trimmer will run and type of material it will trim. The battery can be removed and replaced which makes it more environmentally friendly in my opinion. For the money it looks excellent and in my initial tests is more effective and comfortable to use than the more expensive Bosch Isio.

The Isio has a slightly longer telescopic handle which may be useful if you are 5' 10" or above.

Other Cordless Hedge Trimmers tested by the Fredshed Team


Ryobi 18v Cordless Hedge Trimmer

This no frills hedge trimmer has been around for a few years now and is part of the extensive Ryobi plus one range of cordless power tools. In 2015 it was replaced by a new, more expensive model that has a clippings sweeping attachment and also a rotating handle.

On the old model the blades were not particularly good quality and without the anti jam mechanism of the Bosch 18v models, it did not cut thick material well. I think this hedge trimmer is only worth buying if you have a well kept bush and other Ryobi One + tools so you already have the battery and charger. If you are just buying a cordless hedge trimmer the Bosch AHS 50-20 is a much better tool, and better value when bought with battery and charger included.

There are over 20 tools in the Ryobi range including trimmers, drills, saws, sanders, vacuum cleaners, torches. The hedge trimmer and all the other tools can be powered from the old NiCad battery OR the latest  Li-ion batteries. This is the most flexible system around where all the tools can be purchased with chargers and batteries or without (naked).

18v battery powered long reach hedge trimmers

Flymo Sabre Vs Gtech HT20



Cheaper Long Reach Cordless Hedge Trimmers

Flymo Sabre 18v Telescopic Hedge Trimmer

 Flymo SabreCut Cordless XT Cordless Battery Telescopic Hedge Trimmer, 18 V - 50 cm


Unless your hedge is in a confined space then a long handled hedge trimmer is a great tool to use. They are growing in popularity and come in a range of sizes, petrol and electric and now battery powered. I have tested the Gtech HT05 and HT20, Black and Decker 18v, and Gardena cordless telescopic hedge-trimmers. The drawback with this type of tool is the weight of the head so only consider the longest ones if you are very strong.

The 18v Flymo Sabre Cut is a good low price, long reach hedge trimmer. In 2015 Flymo introduced a improved version with a lightweight 18v Ni-cad battery. This battery has 1.5amp hour of power which is ok for small jobs or thin hedges. Most other manufacturers have moved on to better Li-ion batteries.

In 2016 Gtech launched the 18v HT20 with a 2 amp hour Li-ion battery. It is  shorter and lighter than the Flymo Sabre but more suitable for holding high up and capable of trimming most well managed hedges.

The Flymo does not have the power of the newer Li-ion batteries but for small to medium hedges it is offered at a good price, around 90 against 129 for the Gtech.


    Flymo SabreCut XT Cordless Battery Telescopic Hedge Trimmer, 18 V - 50 cm

The Gtech HT20 is also 18v but with a superior Li-ion battery that can also be used in the Gtech ST20 grass trimmer.

Overall I prefer the Gtech HT20 but it is new, and more expensive so not as tried and tested.

If you want to give the Gtech a go please use the link below

Long reach hedge trimmers are one tool that may be better off petrol powered as the weight can be kept at the bottom end and not the top where it soon becomes seriously tiring. The other issue with long reach tools is that you cant see what you are cutting half the time and have to keep stepping back to check. Also you are likely to leave dead trimmings on your hedge and have to get up there anyway to clear them off properly.

Professional gardeners tend not to use the long reach trimmer much and instead use special Tripod Garden Ladders .

If you have a high, thick hedge then it will be safer to use a ladder platform like the BPS access systems Big Red Foot ladder that I am currently testing. It can be uses like a ladder in a variety of different shapes or as a superb sturdy tressle platform.

Gtech HT05 14.4v Cordless Hedge Trimmer

The Gtech HT05 has a small 25cm blade but long handle (1.7m)

. Initial results were very impressive as the tool is so light yet cuts very well. The 14.4v battery recharges in about 30 minutes, a long tea break.

The HT05 is a more advanced version of my much loved Gtech HT01 that used a separate battery that you keep on your belt.

The  14.4v Lithium-Ion battery in the HT05 is built in, so if it fails the whole tool is landfill. BOOO.

The Gtech ST20 was launched in 2016 and uses a new separate 18v L-ion battery and a belt drive to make it lightweight.

It is longer and heavier than the HT05 and more up to the job.

This is me using the  GTECH HT05 cordless hedge trimmer in 2008.

The HT05 is NOT suitable for thick hedges as its maximum cut is about 6mm on woody stems.

Please be aware that due the built in battery this tool must be considered to have a limited lifespan and be disposable when the battery fails!

Sadly there are quite a few reports of the batteries failing in this tool after a year or so which then renders it to landfill. The new HT20 model solves this issue by having a separate , replaceable battery. Also the blade can be swapped for a spinning saw so in theory if the blade wears out it should be easy to replace it too.

I am currently testing the larger Gtech HT20 and like it. I have not tested the pruning saw/ branch cutter attachment as I have tried these on other tools and found them to be a bit useless compared to a decent simple saw on a stick.
