Makita XRU09PT1 String Trimmer

Why Choose Battery Power?

Convenient mobility is a huge selling point. Battery-powered weed eaters are a great option for anyone who does not want to be tied down by a cumbersome cord.

When you are putting the finishing touches on your landscape, the last thing you want to have to worry about is whether or not your extension cord will reach the area you need to finish. Plus, cords can also present a tripping hazard when stretched across long distances.

Batteries are better for you and the planet. Battery-powered weed eaters are often much lighter than gasoline-powered units. This variation in weight can make the difference between a good day of yard work and a day that results in a sore back.

Battery motors are also quieter; less noise means less hearing damage from prolonged use. Plus they are just much better for the environment.

Buyers Guide: What to Look For in a Cordless Weed Eater

Now that you know the benefits of going cordless, let’s talk about what you should look for when you go to buy your new weed eater.

Battery Life and Power

One of the drawbacks of using battery power is that batteries can run out of juice. This is why it is essential to consider the amount of work you are planning on doing so that you know what to look for as far as battery life. Some batteries can last as little as 15 to 30 minutes, which does not sound like much, but if you have a small yard or only a few spots you like to trim, this may be just right for you. Some batteries can last upwards of an hour. This will be a much better choice if you have a bigger space to cover.

Another thing to check on when it comes to battery life is charging time. Different batteries charge at different rates; some take hours, others have quick charge options. It is all about choosing the battery that fits your work style.

Only need the battery to last for one go? Then a longer charging time won’t be an issue. Plan on doing continuous work? Definitely check out the quick charging options.

Battery power is another critical element. Another reason people choose gas-powered over battery-powered is that gas weed eaters are more powerful, making them better for tougher jobs. Not to worry though, if you have tougher weeds there are still cordless options for you. Look for 60v to 80v for tougher jobs. Otherwise, if you are just expecting smaller jobs, then 40v will do just fine.

Not All Weed Eaters Are Created Equal

Every person and job if different, so you must choose the weed eater that fits both you and your level of work. Be sure to test the weight and balance of the weed eater you are looking at so you can be sure to choose one that you are comfortable carrying around. Keep in mind how much ground you will need to cover.

The weed eater might feel light enough when you first pick it up, but will it still feel light after 30 minutes to an hour of work? What about the length of the weed eater? Make sure it does not make you feel awkward or off balance. This is a serious safety concern. Make sure you are comfortable supporting and moving around with it.

Much like with the battery power, you also have to think about what type of job you are doing when you choose the style of your weed eater. For example, if you have tough weeds, you will probably want to look for dual cord, instead of a single cord weed eater. Have some edging you want to do? Some weed eaters can be converted into edgers. You could choose one of these and then you would have two tools in one, saving money and still getting the job done.

Quality

Last, but never least, consider the quality of what you are about to purchase. It is easy to fall into the mindset that more expensive means better, but sometimes that is not the case. Instead of thinking of the quality in terms of money, think of the quality of this tool in terms of yourself. How much quality are you going to get out of a super powered, ultra weed eater when in reality, you only need to tidy up the edges around your house? Do not overspend, choose wisely, and you will not regret it.

All of that being said, let’s take a look at a few quality cordless string trimmers so that you can make an informed decision with your next purchase.

Summary

Choosing the best cordless string trimmer can be challenging, but now that you are armed with all this information, you can be comfortable making the best decision to meet your requirements.

Each of these cordless weed eaters offers options that are right for different levels of work. Just cleaning up around your mailbox and front steps? Choose one like the Dewalt or WORX. Need something more heavy duty? Then the Makita, with its extra long battery life and high power, would be the one.

How about something in the middle? Choose the Greenworks or Black+Decker and you will have all the power you need to keep your sidewalks and gardens free of those pesky weeds. Just remember, we created this list to inspire and inform you so that you will have the tools you need to choose the right quality battery weed eater for you.
