When it comes to maintaining a tidy, manicured garden, few tools are as essential as the humble hedge trimmer. Cordless, battery-powered models provide the ultimate in convenient trimming thanks to their lightweight, go-anywhere portability.

But with numerous models on the market sporting an array of features, how do you select the right cordless hedge trimmer for your needs? This guide breaks down the key factors to consider when choosing a battery-powered hedge trimmer for your garden

Battery Voltage

The battery system is central to determining how a cordless hedge trimmer performs. Higher voltage batteries supply the power for the motor and cutting blades, allowing for longer runtimes between charges.

While smaller 18V batteries are a popular choice, higher voltage models ranging from 20V to 40V will remain operational for more extended periods.

This translates to increased cutting capabilities before you need to recharge. So the more hedge trimming you need to tackle, the greater the battery voltage you need powering your hedge trimmer.

A standard 18V model can handle adequate trimming within a small or medium-sized garden. But larger and demanding properties require more runtime, so a 36V or 40V model becomes the better choice.

Just understand that higher voltage machines will weigh more due to the battery capacity. If reduced weight is crucial, 20V units combine exceptional cutting power with lighter operation. Splitting the difference, 24V to 28V models provide excellent energy for chore needs without the extra weight.

Charging Times

Part and parcel with the advanced battery technology that powers modern cordless hedge trimmers is vastly improved charging times compared to ever before. Where older tools saw extensive downtime attached to the charger after a single battery use, newer batteries can recharge to full capacity in under one hour in many cases.

Short charging times seem ideal when you have lots to trim. However, perhaps consider a battery which may take slightly longer at 90 minutes but will run and run once fully powered up. This way you can swap out batteries as needed rather than having the trimmer stop midway through a big job.

Many cordless hedge trimmers now come supplied as part of systems which include an additional battery and rapid charger as standard. This gives you the flexibility to charge one battery while utilising the other to continue trimming uninterrupted. For those with extensive garden care, this dual-battery arrangement proves invaluable.

Noise Levels

One significant advantage of battery-powered tools over petrol models is vastly reduced noise and vibration. Petrol hedge trimmers create an ear-piercing racket, usually around 100 dB in operation or more. This not only risks hearing damage with prolonged exposure but makes trimming an unpleasant, jarring experience.

In contrast, cordless electric models operate very quietly as a rule of thumb. Most quality battery hedge trimmers generate only 65 dB to 75 dB while running. That’s about the same volume as an average conversation, meaning you can trim hedges without disturbing the neighbours or wildlife.

Premium low-noise trimmers can reach decibel levels closer to 60 dB for near-silent function. This allows trimming while enjoying music or a chat with friends, transforming an arduous chore into a relaxing garden activity.

Cutting Length

The cutting blade length determines how much material the hedge trimmer can cut in a single pass. Longer blades span a more extensive area to trim more hedge with each motion. A blade length exceeding 50cm helps make fast work of wide, overgrown hedges and substantial cutting jobs. The extended reach also reduces hand fatigue that can come from making multiple passes to achieve the desired neatly trimmed finish.

More diminutive gardens are often dotted with smaller hedges, meaning less cutting length is necessary. For anyone needing to access tricky areas like under low overhangs, around tight corners or craft intricate topiary shapes, smaller 30-40cm blades prove optimal.

Shorter blades grant you superior accuracy and control while sculpting foliage to perfection. So first consider your typical trimming tasks to choose the appropriate cutting length hedge trimmer for your needs, be it an extensive or compact blade.

Getting Equipped

Weigh up these essential factors – battery voltage, charging times, noise levels and cutting length – to select a cordless hedge trimmer tailored precisely to your garden’s needs. Opting for higher voltage batteries with fast charging functionality allows you to power through large trimming jobs without delays.

While low-decibel operation brings the pleasure back to hedge trimming anytime you need it. With this battery-powered equipment, you’ll craft pristine hedges and stunning topiary across your outside space while enjoying the perfect synthesis of power and peaceful operation that cordless trimming provides.
