Factors to Consider When Choosing the Best Battery Trimmer

As there are many options available in the market you may find it hard to choose the right one. They are many categories present differentiating them in some specs. If you don’t know what you are looking for you might end up wasting money.

Some of the basic factors to consider before shopping for the electric trimmer for your garden area

Yard size

The size of the yard is a very important factor. This determines the power of the tool required to finish the trimming. If you buy a less powerful cordless trimmer you might be needing recharging or a change of the battery more often during the process. This will ultimately increase the time of the whole process considerably. Hence, put the size of the lawn first before buying.

How often trimming is required

The time you have for taking care of the lawn is quite important. If you are very busy and mow lawns after a considerable length of time, you might require a tool that trims and decreases the growth of grass and weeds quickly. On the other hand, if you can mow the lawn often, any handy tool will be sufficient.

Apart from these basic factors, some technical specs should be carefully searched before buying, to have the best cordless grass trimmer. Some key considerations are as follows

Trim Width

Trim width, also called “swath width,” is the area covered by the blade while trimming. It tells us the amount of grass that the trimmer will clean in a single pass. Normally the tools available in the market have swath widths of 10 to 18 inches.

The wider the width, the less time required to clean the whole lawn. Thus, look for the best width option available in the market to get the job done in less time.

Battery Type

The batteries available in the market for the string trimmer are of two types

  • Lithium-ion (Li-on)
  • Nickel-cadmium (NiCad)

Lithium-ion (Li-on)

Li-ion batteries are more powerful and thus costly. They provide the best possible power to the equipment for getting the lawn trimmed in no time. They are also small and easy to handle than the other heavy batteries.

Nickel-cadmium (NiCad)

NiCad batteries are less powerful as compared to the li-ion but are also very less expensive. These batteries greatly reduce the cost but may be less effective, however, if used wisely they can be of great help. 

They also have a “memory effect,” i.e. if you use the battery before it is fully recharged or if it’s recharged before it's fully drained it will always remember the charge levels and won’t charge to a higher level ever in the future.

So considering your budget you can choose any one option but use it carefully to get the best result.


The power at which the battery operates is indicated in volts. Most of the cordless weed eaters with batteries and chargers available in the market have 18-60 volts of power. The more powerful the batteries are the more effective the trimming is. 

It will also take less time and cover more area if the volts are higher than a battery. But it affects their cost as well. High voltage batteries are very expensive. Watch out for the volt a tool’s battery is providing.

You can also buy the batteries separately afterward.

Feed Type

The string trimmers use a feed or string to cut the grass. They are made of plastic or some other composite material that spin at high velocity and trim the weed and grass. All the mowers have a “feed mechanism” that releases the string into the base as it wears down after usage.

This mechanism can be of 3 types

  • The bump feed system: where the string is released by bumping the trimmer on the ground.
  • An auto-feed system: in which a sensor is present that releases the string automatically when needed.
  • A push-button system: where a button is pressed to release the string.

All of these methods have their advantages and disadvantages. While the bump method is quick and efficient it may cause damage to the tool. The push button and auto may have some safety features but are not used in commercial trimmers. You should consider the feed mechanism before buying the machine and choose the one best suited for you.

Curved vs. Straight Shaft

String trimmers also come in two shapes i.e. straight or curved.

Curved-shaft trimmers

Curved-shaft trimmers are best suited for short-height users as they are curved at the end and make an angle that is very comfortable for them.

Straight shaft trimmers

Straight shaft trimmers are preferred by tall people and can be used as more than 1 type of tool. You can attach different trimming heads at the end and use them as a tree trimmer, bush shapers, etc.

All of these factors can help reduce the wrong ending of your purchase. So, consider them while buying the best cordless grass trimmer. 


The string trimmers are very important tools in order to cut and trim the overgrown grass and weeds. They are mostly used for smaller lawns where mowers cannot get the job done. Also, they are the best for clearing edges of your garden or shaping bushes. They are very handy, economical, and eco-friendly tools.

In order to buy the best cordless trimmer, you should look for their:

  • Battery type
  • Battery voltage
  • Cutting swath
  • Line diameter
  • Weight
  • Feed mechanism
  • Price

All of these are discussed in detail in the above-mentioned products so that you can easily choose the best cordless string grass trimmer according to your requirement.          


What maintenance does a battery-powered string trimmer need?

While using the battery-powered trimmer you should take some basic care of the device in order to get the best out of it. Some simple instructions to follow are.

  • Clean the head regularly to ensure no grass residues are present.
  • Charge the battery completely before using it.
  • Do not charge the battery until it is completely drained.
  • Replace the string line as needed.

How to use a bump feed trimmer?
