Are you getting bored of refueling the gardening tools? Cordless string trimmers are the best options in case you want a convenient and eco-friendly alternative. Primarily because you don’t have to worry about oil or gas supply. Also, there are no cables that you need to manage.

There are certain factors you need to check before investing in a cordless hedge trimmer. Battery power should be your first concern, but due to the latest advancements, it’s possible to get a string trimmer that can complete the maintenance task without looking for recharge. Let’s discuss all the other features as well.

Battery Type

Cordless string trimmers are available with two types of rechargeable batteries. No matter what kind of trimmer you choose, it will consume the battery only when you squeeze its trigger. So, a cordless grass cutter will last longer if you interfere with its trigger only while trimming.

Lithium-ion: Mostly used by the modern string trimmers, Li-ion is the latest invention to power a wide range of gardening tools. If you need fade-free power and improved performance, then you can try a string trimmer with Li-ion cells. Moreover, these batteries are lightweight and live a longer life because you can charge them for up to three times as a Ni-Cad battery.

While using a Lithium-ion battery, you will never notice power degrade, even when the battery is low. You can choose one of these cells anywhere between 18 to 84V. Check the required voltage whenever you purchase a replacement battery for your unit.

Ni-Cad: Old school string trimmers are still using Ni-Cad batteries, but they are heavy and shows power drop off as the charge goes down. These batteries were famous in the past because Li-ion technology was comparatively expensive. However, now Ni-Cad batteries becoming obsolete. So, if you are going to maintain your garden for many more years, then Lithium-ion strimmer is a better idea.

Runtime or Battery Backup

Consider the battery life or backup while choosing a cordless trimmer. The maximum runtime you can enjoy is up to 60 minutes. So, you need to select a device and its backup according to your garden size. You can also invest in a spare cell to be on the safe side, especially if you own a significant yard.

Apart from the runtime, you should also consider the charging duration of a trimmer. Current models consume anywhere between 2 to 5 hours to complete one charge cycle. Some of the models also have a quick recharge option, but they are comparatively expensive.

Shaft Design

You will find two types of shaft construction while browsing for string trimmers.

Straight: Most common design, a cordless trimmer with the straight shaft is easy to work under the fences and other tough to reach areas. Some of the models come with a telescopic shaft so that you can change its length according to your preferences. For instance, Worx WG163.10 GT 3.0.

Curved: String trimmers with curved shafts are less in numbers because they are difficult to reach tight corners. If you have open areas, then there are no problems in trying a curved strimmer. Such a gardening tool is also great for beginners.

Dual Functionality

String trimmers are also capable to work as an edger. Most of the available options are built to work as an edging device, but holding a gardening tool at the same angle might not be easy for all of us. Some of the new variants like Worx WG163.10 GT 3.0 are available with an inbuilt wheel that assists while edging. You might opt for such a feature because it reduces strain in your wrists and is especially helpful if you own a significant lawn.

Trimming Line

Cordless string trimmers either comprises a single or double string to deal with the plantations. It’s easy to guess that a trimmer with double strings can cover more ground when compared to single string models. So, try a double string trimmer for large grounds.


Follow the above-given factors and you can find one of the best cordless string trimmers without spending much time. If you check the battery type, runtime, weight, and cutting swath, you will be able to find a suitable gardening device that you can use for many more years to come.
