Advantages of cordless technology
Since its invention in the 1970s, lawn mowers have become a mature and almost indispensable component in many outdoor power tool kits, but until recently, advances in affordable battery technology have provided consumers with more and more viable options. Alternatives to gasoline or wired motors that have historically dominated the market. Although gasoline internal combustion engines have always provided the best combination of power, running time and freedom of movement, the functionality of today's battery-powered machines is an attractive option for many users.

Compared to wired motors, the operation of battery-powered power grass trimmer is very similar, but not towing the power cord is a huge benefit for many gardeners. Cutting the power cord gives you more freedom, almost eliminates setup time, and saves you from the frustration caused by the wire being stuck or tangled. More importantly, they are a safer alternative than long extension cords from the house to the outdoor environment.

So if you are buying a new cordless lawn mower on the market, or are considering switching to battery power, what should you look for?

Battery platform
Before you start deciding which cordless lawn mower to buy, it’s worth pointing out that you can buy a device that is compatible with the battery and charger you already have and save yourself some money in the process. For example, many people may not realize that they can buy a lawn mower as a bare machine and use it with the battery in the drill rig. Large "home and garden" cordless platforms have always provided a wide range of DIY and gardening tools, but recently many professional power tool brands have begun to venture into the outdoor market as well. If you can stick to one platform, you will find it easier in the long run, even if you don’t have any cordless tools, it’s worth looking at what other tools are available on the manufacturer’s battery platform before making a decision If you want to add more later.

Battery chemistry
The current dominant battery is the lithium-ion (li-ion) battery, which has several advantages over older formats such as NIMH or NICAD. Lithium-ion batteries can be stored for longer periods of time without losing charge, and can be charged at any time without damaging the battery. In order to improve efficiency, many manufacturers have begun to combine lithium-ion battery power with brushless motors. Brushless motors generally provide a higher torque-to-weight ratio, less mechanical wear, and longer service life. Using lithium-ion machines from established manufacturers should provide the best long-term sustainability, because if you need them, you may still be able to find spare or replacement batteries further away.

Variants and accessories
In addition to the specific factors of battery-powered trimmers, first-time buyers or inexperienced users may also need to pay attention to other considerations based on the work that needs to be done. If you may want to remove heavier leaves (such as thick clumps overgrown with weeds), it may be worth investing in a brush cutter. These are usually designed to be equipped with a line for mowing grass, or with heavy-duty brush cutter blades for more intensive cleaning work. The shape of the tool is also worth considering: some users find the curved design more comfortable to use, although the straight shaft provides better access when working under obstacles such as bushes or garden furniture. Similarly, if you are particularly tall or short, you may need to check the overall length of the machine or whether it has an adjustable shaft to ensure comfortable operation. Trimmers and brush cutters can throw stones and other debris from the work area, so you should always make sure that you have some form of eye protection on hand before you start using the tool.

If you want to trim your entire garden, the tools you need are not just lawn mowers, you should also use telescopic pole saw, which can help you trim tall branches well.
