When shopping for a new string trimmer, who doesn’t love the idea of one cordless tool that can be used for everything? But most people instead choose two separate tools: gas-powered for the big jobs and electric-powered for the little ones. Today, we’re kicking it up a notch with a string trimmer that works as well as either.

The RYOBI 40V Cordless String Trimmer has three key features: the power to spare, attachment capability, and affordability. There’s only one word needed to explain the first two: gas-like. The trimmer is perfect for yards up to 1 Acre in size.

Where other battery string trimmers typically deliver around half or even less of what a gas line trimmer can do on its best day, this thing delivers nearly 70% more than comparable gas trimmers. The trimmer comes equipped with an extra 0.08-inch twisted line which allows longer runs between charges while still providing fast reloading times.

The 40V RYOBI Cordless String Trimmer also has the attachment capability you need to get around obstacles and between closely planted bushes without getting stuck repeatedly. Last but not least, the price is very affordable, especially when you consider all that it can do for your lawn or yard.

Despite its lightweight design, thanks to the brushless motor technology that allows this machine to perform better than other models on market today. You can easily cut through thicker areas of grass or weeds without stopping frequently to recharge or refill the string head. It is also ideal for people with back problems who find it hard to use a heavy weed wacker.

The battery takes around 40 minutes to charge fully but its run time is equivalent to around 30 minutes, lesser than some cordless trimmers in the market today. You can purchase an additional 2Ah battery if you want more runtime for your work. The 18-inch telescoping pole allows you to adjust the height of your string trimmer according to your specific preference.

Just like most 20-volt electric outdoor equipment by ALM, this weed eater runs on a 20-volt lithium-ion power source that produces just as much power as gas engines do.

Best Battery Powered String Trimmer Buying Guide

After reading products reviews, you have probably 1-2 models that excite you. And the buying guide helps you narrow down the choice for the best battery powered weed eater.

Why Battery Powered String Trimmer?

If you’re looking for the best battery powered weed eaters, consider these advantages.

  • First off, they don’t produce emissions like gas-powered models so it’s much better for your health and environment – not to mention quieter.
  • Plus there’s less maintenance involved since you won’t have store fuel or mix oil with gas. Lastly but definitely not lastly: affordability thanks in large part from their lower operating costs (more about this below).
  • A battery-powered weed eater is lighter and easier to start than gas models, but it has its limitations. It may only last 30 minutes or up until an hour of usage at most–in which case you’ll need another one for your large yard work.
  • For job that takes a long time, you may have to stop and recharge the battery in between. This can be extremely inconvenient since some batteries take several hours or more before they’re full again.
  • Battery-powered motors tend not only break easier than gas counterparts but also generally prove less powerful as well making it difficult work with these tools on hand if one becomes exhausted by its own power source.

Things to consider when purchasing the best Battery Powered String Trimmer

Knowing what brands and models to look for when shopping can be tough, but we have a quick guide that will help. Here are some things you should consider when purchasing the best cordless string trimmer.


The upfront cost of switching to a battery system is usually higher, but the long-term savings are worth it. You may have an easier time finding deals on batteries if you’re located near certain suppliers or manufacturers who can get them for less than the usual market price.

Our preference is always towards residential kits which start at around $175 with bare tools being cheaper still – expect prices in this range when looking at commercial products as well ($250-$400). Combo deals often make sense because some brands offer them alongside their high-end tools; if that’s what your budget allows then by all means take advantage.


When you have a tough job that needs to be done, it can take some pretty strong tools. That’s why there are batteries with higher voltages for heavy-duty tasks like trimming overgrown grass and weeds in your yard or patio area (and other properties).

Brushless motors offer longer life, more run time, and power than their brushed counterparts. Brushed motors are great for those who have small yards because they won’t hog all the space on your property. But if you want something reliable in every situation regardless of its size then think about getting yourself one with brushless technology.

Line Speed

One of the most important factors in a weed whacker is its RPM. The higher this number, the better for thick grass and tough weeds because they can weed whack all day without getting worn down as easily from constant contact with soft clovers or other plants that don’t have much resistance against your blade’s cutting edge.


When you pick up a battery powered weed eater and pull the trigger, feel for how much vibration makes it to your hands. If that feeling is too harsh on contact or even just in-between shots then consider looking elsewhere because this was one of our main concerns when choosing tools.

Cutting Swath

The cutting swath (or width) of a weed eater determines how long it will take you to trim an area. A 10-inch wide blade can only cut for ten inches at once so if there are small spots that need finishing in tight spaces then go with something wider like 15 or 18-inch blades instead.

Run Time

The trimmer needs to be used for at least 30 minutes to create an effective lawn. If you have a large yard that requires more than just 15 or 20 minutes, consider picking up one of our higher capacity batteries because they will last longer on average before running out of power again.

If your home’s grass is too long and hasn’t been cut recently (or ever), then this may not bode well. You’ll need something with enough juice or a backpack battery.

Line Diameter

For residential string trimmers, the 0.080-inch line is typically fine for most landscapes. If you have a larger lawn or tough areas to trim and your grasses are on the lighter side of things, consider upgrading with at least 0.095-inch capacity so that it will last longer during those tough moments when all eyes need their strength.


One of the most important considerations when choosing an appropriate weight for yourself is knowing what your limits on lifting capacity are so you don’t end up wearing yourself out much quicker than necessary.

If carrying becomes too difficult due to fatigue or shoulder pain then consider opting instead into buying one that attaches onto shoulders via strap – this way there’s less strain put onto these joints while still allowing use; something which would ultimately serve them better long term anyway.

Compatible Tools

To get the best deal, buy one battery system for all your lawn equipment. You may want to consider adding more if you find yourself buying other batteries in the future since they are less expensive than having several different types of power tool batteries and will save money.

Are battery Powered Weed Eaters any Good?

Yes, many people say that a battery weed eater is better for residential use.

How to Maintain a Battery Powered String Trimmer?

Battery powered weed string trimmers have the same maintenance and care needs as other kinds of string trimmers. The most important thing to do is remove gunk buildup in your cutting head, so use these steps:

1) Remove the battery by switching off the power button or using a cleaning brush with soap water when needed for stubborn spots.

2) Change line every month depending on frequency/usefulness (depending on whether you’re just trimming around fences).

3) Be sure no foreign objects are left inside beyond what’s expected from regular usage.

Is battery Powered Weed Eater Work in Wet Grass?

It is not recommended to use a cordless weed eater on wet grass. Not only will the blade become difficult and wear out more quickly, but you might as well just go ahead with your traditional one instead of risking having an uneven yard due to these issues – this also includes sloppier cuts too.

Which is batter? Gas vs. Battery Powered Weed Eater

When deciding on a string trimmer to use around your property, consider how much maintenance is required. For example, if you have an overgrown yard and need the cutting power of gas-powered machines.

Then it may be worth looking into these as they will require more work from yourself from time spent trimming up all those weeds that seem impossible with cordless tools only providing battery life for their own gadgetry needs. Which can sometimes lead people down paths where batteries die out before being finished working.

So, even though some models do come equipped with replaceable ones many still prefer them since there’s no risk involved when investing in one type or brand.

Final Verdict

Did you know that the best battery powered weed eater offers a good balance between power and portability? It’s important to consider what your needs are before deciding on this purchase, so it’s worth thinking about how much time you spend outside in your yard.

For example, if you have an extra-large lawn but don’t want to invest in gas or electric-powered tools because of their price tag, then investing in the best battery powered weed eater might be right for you.

This way all of your gardening chores can be done without any fuss whatsoever – just plug it in when needed and go about your day while still getting work done. There are many options out there (we love
