What’s great about the best battery-powered weed eater is the fact that they combine the convenience and ease of gas string trimmers with the strong points of electric devices (comparatively silent operation, maintaining the engine is not needed, no emissions, and start button).
Just thinking back a few decades ago, they were almost no cordless products that had the battery life and the power to be considered as a good investment. It’s different these days, though. Nowadays, things have changed. We have cordless string trimmers that are both practical and durable. While they may not yet be at the same level of gas-powered models, they still deliver a bang-up job. We’ve come a long way in the power tool industry, haven’t we?
For performing small trimming jobs only, a battery-powered string trimmer is a great low-cost investment. And the fact that they are cordless and run on VC batteries means that you won’t have to be restricted by any cords. Wireless string trimmers will give great results when dealing with errand weed and grass growth. But you must know that most of them will not be able to handle hard weeds and brush like gas trimmers can. The evolution of the batteries and the technology involved in making them has greatly affected the performance of the cordless electric trimmer.
If you’re looking for the best battery-powered weed eater but feeling overwhelmed by the great number of models available today, grab a cup of coffee, as you’re going to want to stick around. In this guide, we’ll be reviewing the best battery-powered weed eaters available today and detailing the main features that you should consider before buying.

Choosing the Best Battery-Powered Weed Eater – Buying Guide
If you’re still not certain about what kind of weed trimmer you want to get, then this buyer’s guide should clear the confusion. We’re going to break down the most important factors of this kind of product. You’ll know exactly what you need once you finish reading it, especially if you’re a beginner in the field
The great thing about the best battery-powered weed eaters that they are very light compared to gas-powered ones. You can find units as light as 10lb or even less. If you don’t want to be tired at the end of the day, this is a feature to look out for.
You can sometimes tell by the weight of the model that some poor design decisions were taken during production. Motors for battery-powered weed eater are much lighter than those of gas-powered ones. Unfortunately, some manufacturers will cut corners and use heavier yet cheaper material to construct the weed trimmer.
A heavyweight can also be an indicator of an old battery. Today lithium-ion batteries are used everywhere because they are light and they pack significant amounts of energy. Some manufacturers might decide to go with older types of cells which will be heavier than lithium ones. Like Nickel-cadmium batteries. They are cheaper but heavier and undergo a significant drop off in power when compared to lithium-ion batteries.
Power of the Best Battery-Powered Weed Eater
The major concern for anyone switching from gas-powered trimmers to electric ones is the downgrade in power. While we haven’t reached equivalence between the two, electric trimmers, including the best battery-powered weed eaters, are now closer than they ever were to having the same potential of gas-powered trimmers.
If you’re going for an industrial scale type of task, then your best bet is a gas-powered trimmer. It’s not that battery-powered ones can’t do the job, but the gas-powered trimmer will do the job with a single tank, whereas you’ll have to charge the batteries of electric one at least once before getting the job done.
But in the case that you have only an acre or less of home lawn to take care of, then a battery-powered trimmer will do the job just fine. You can get half an hour of work even from the below-average weed trimmers on the market. The great ones will give you even more than an hour if you’re using them in low-power settings.
Power is measured in volts when it comes to electric trimmers. You’ll find 20-volt models and 40-volt models. The 40V models will give you more power, but they will drain the power faster. You can make up for this by getting a bigger cell or having a spare one charged for whenever you might need it. The size of the battery is measured in ampere-hours. Top-quality ones will have 5 amp-hours of power. You’ll be using more than just one amp when trimming the lawn. So don’t expect 5 hours of straight work in one charge.
Cordless machines, such as portable table saws, cordless circular saws, cordless pole saws, and the best battery-powered weed eaters depend on cells to function, which is why you need to consider the battery life before buying such a tool.
Lithium-ion batteries are good because they are lightweight and they pack a lot of power. But sometimes even having one isn’t enough, especially if you’re dealing with a large lawn. It is advised in this case to have more just one charged battery by your side when trimming.
Now, this may seem like a pricey way of handling things. Fortunately, companies found a way to help out with this. Some companies like DeWalt, for example, will produce a line of products that use the same kind of battery. This means if you buy three distinct products from DeWalt of the same line, you will get three batteries for you to use for those products whenever you need.
It’s unlikely that you would use these three same Line Products simultaneously. So you won’t have much trouble finding a charged spare battery whenever you need as long as you make sure to charge your batteries when you’re done using them. And if you’re torn between two cordless trimmers, you can break the Tie by buying the one that was produced in the same line of products as a tool that you already own.
If you don’t like being hit by smaller rocks, bits of plants, and debris when you’re using your trimmer, then you might want to consider getting a good guard quality in your best battery-powered weed eater. It’s always advised to wear long pants whenever you are operating the trimmer, but if that’s not an option then a good guard we’ll save you a lot of discomfort.
A balance must be struck between the quality of the guard in the weight of the trimmer. A good guard will be heavier so that will add to the weight of the tool. You have to find the trimmer that strikes the right balance for your preferences.
It’s worth mentioning is that trimmers that double as edgers usually don’t have good guard because they would have to be operated at two different angles which might leave you exposed.
At some point after a certain period of using the best battery trimmer, you will have to replace the weed eater’s line. This can either be inconvenient or quite simple. You have to remember that thicker line gauges will last longer. But they are heavier and drain more power. This, of course, may reduce the operating time of the battery.
There are of course, models that have an automatic feed. This will extend the line if you ever need it. It’s a good feature and decreases the need for replacing the line manually. The second best option is a bumping mechanism. you have to stomp the spinning head on the ground as you work to release more line.
Some other products may release the trimmer line where they are turned off. It may be a little strange to turn your weed trimmer on and off as you work, but starting it up again is almost instantaneous so it won’t waste you anytime.
Of course, there are other models that need you to set the length and feed the wire manually. This one causes some inconvenience, but the good thing is that you can find better systems at the same price.
No matter which power tool you’re getting, be it the best battery-powered weed eater, log splitter, TIG welder, or even gas leaf blower, it’s essential to pay special attention to how easy maintenance would be as that can make or break your experience.
The way that you have to replace the trimmer line will depend on what kind of weed eater you’re using. There are single-line trimmers and dual-line ones. If you’re going to wind the line yourself, use a pre-wound spool or pre-cut line pieces.
When replacing the line, you have to make sure that you’re using approved replacement parts only. Inspect the trimmer for wear and tear and clean the area circling the weed eater’s head as well as the cutting shield.
Before you put the trimmer away, make sure it cools down. Clean it from any clippings or debris and lubricate it if needed. It can be sprayed with light oil to avoid rusting. It must be stored in a well-ventilated, dry area. Keep it away from children’s reach.
All in all, cordless trimmers need very little maintenance. That said, you should always make sure to read the instructions before taking any action.
