15 Best Battery Operated Weed Eaters for a Neat Backyard

{“statusCode”:401,”message”:”License key missing”}

Whether you call it a line trimmer, a weed eater, or a whipper snipper (as the Australians do), it remains one of the best solutions to cutting grass or weeds where a solid blade would be neither effective nor safe.

The continued development of electricity storage technologies ensures that batteries get smaller, last longer, charge faster, and deliver more punch. Add the ability to charge them off the grid, and you have a solution to noise and air pollution on a machine that does what only it can do – the battery-powered string trimmer.

We reviewed more than 40 battery-powered line trimmers and shortlisted 15 for your consideration. We then categorized them according to price and Amazon reviews. Let’s look at each one in-depth and see what could work for you. We’re also going to look at some interesting science facts – calculating the actual speed of the line as it cuts through the plants (theoretically). Enjoy.

1. Makita XRU15PT1 36V (18V X2) LXT

Over the decades, Makita has built a formidable reputation for quality and innovation. As string trimmers go, the Makita XRU15PT1 36V LXT is in a class of its own. While we looked at other machines incorporating some technology (like torque response), Makita outperformed them all.

Their direct drive BL Brushless Motor system provides the highest power and most intelligent torque response to varying environmental demands. When you need power, the machine gives it to you, and when there is less demand placed on the motor, it automatically adjusts, lowering the revs.

The automatic torque-drive mode only shifts from 3,500 to 6,500 RPM when power is required to optimize run times.

Speaking of RPM (revs per minute), at 6,500 RPM, how fast is the string moving on a 15-inch diameter?

Circumference = diameter x PI = 15 x 3.1416 = 47.124 inches

At 6,500 rpm, the tip of that 0.080-inch string is covering 306,306 inches a minute (6,500 x 47.124)

There are 63,360 inches to the mile, so our little string covers about 4.83 miles (306,306 / 63,360) a minute or 290 miles per hour (4.83 x 60). Yep, that’s seriously fast.

The Makita XRU15PT1 36V LXT has 3-speeds:

  • Low: 3,500 RPM
  • Medium: 5,300 RPM
  • High: 6,500 RPM

With its 15-inch cutting swath, you get added productivity.

Protecting your battery from overload, over-discharge, and overheating is the bespoke Star Protection computer controls™ for efficient power management.

  • Overload protection allows the battery and tool to communicate to protect from overload.
  • Over-discharge protection extends battery life by stopping the tool when the battery is low.
  • Overheat protection monitors battery temperature, stopping the tool before the battery is damaged.

Landscapers are demanding more cordless alternatives to gas-powered outdoor power equipment. Makita meets demand with an expanding line-up of cordless OPE (Outdoor Power Equipment), including the flagship 18V X2 (36V) LXT Brushless Cordless String Trimmer Kit (model XRU15PT1). With zero emissions, lower noise and considerably less maintenance than gas-powered string trimmers, the 18V X2 (36V) LXT Cordless String Trimmer is a welcome solution for landscapers.

It’s powered by two fast-charging 18V LXT batteries for maximum power and run time without leaving the strongly preferred 18V battery platform. Electronic controls efficiently use battery energy to match the changing demands of the application for increased power and speed when needed.

In addition, the string trimmer rotates in the same counter-clockwise direction as professional-grade trimmers and uses industry-standard spindles (M10x1. 25 LH) for added convenience. With the efficient Makita BL brushless motor, the trimmer delivers a longer run time, more power and speed, and longer tool life.

Makita’s efficient BL Brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per battery charge than similar non-brushless tools. The XRU15PT features a Makita-built Outer Rotor Brushless Motor with direct drive, providing high power and increased torque.

The String Trimmer features Makita Extreme Protection Technology (XPT). XPT is a protective seal inside the tool and is engineered for improved operation in harsh conditions by channeling water and dust from key internal components. It’s part of Makita’s expanding 18V LXT System, the world’s largest cordless tool system powered by 18V lithium-ion slide-style batteries.

Makita 18V Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. Makita created Star Protection Computer Controls to improve tool performance and extended battery life.

Star Protection is a communication technology that allows the Star Protection-equipped tool and battery to exchange data in real-time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18V LXT and Compact Lithium-Ion batteries, with the star symbol on the battery indicating star protection inside.

Makita is a Japanese company that operates factories worldwide, including the U.S.A.

Picture of the WORX Nitro WG186.9 and Amazon review stats

The Worx Nitro WG186 40V Power Share Cordless Attachment-Capable Driveshare 15” String Trimmer was designed to give any lawn or property professional-looking landscaping results.

Drive share is the Worx system of lawncare attachments (sold separately) that turn your String Trimmer into a Hedge Trimmer, Brush Cutter, Pole Saw, or Edger. Save money and space by purchasing the Driveshare system rather than 5 separate tools.

You gain the capability of an entire lawncare detailing system when you start using Drive Share. But its gas-like performance truly sets the Nitro 40V String Trimmer apart from your average battery-operated trimmer.

Frequently Asked Questions

Does this come with a battery and charger?

Yes, this model comes with two batteries and one dual-port charger.

This is advertised as a 40V Power Share™ product. What does that mean? What’s the difference between this and a 20V WORX Power Share™ product?

WORX has been offering 20V garden and power tools for a long time, and we’ve gotten a lot of feedback from customers like you. We’ve taken all of it seriously. We know what it takes to invest in a line of power tools only to discover you need more power.

Can I use just one battery at a time if I don’t need as much power?

The 40V Power Share™ tools are designed to work with a pair of batteries and will not operate with just one battery installed. For optimum performance, when pairing up your batteries, we recommend that both batteries are the same Amp hour rating and are fully charged.

I have multiple batteries. How can I tell if I’ve put the right ones on my String Trimmer / Edger?

Before starting the trimmer or after use, press the button beside the power indicator light on the machine to check the battery capacity. During operation, the battery indicator will constantly sense and automatically display the battery power indicator. With two battery packs, the power indicator light will display the battery’s condition with the lowest power level.

Can I adapt the 13” Cordless String Trimmer / Edger to my height?

The WORX 40V Power Share™ 13” Cordless String Trimmer / Edger has a static length but is equipped with an adjustable auxiliary handle so you can customize the fit of the trimmer to a grip for your height and comfort.

How heavy is the trimmer?

The trimmer weighs 8.6 lbs., even with both batteries installed. The ergonomic design ensures the weight is evenly distributed between the main and auxiliary handle, making trimming a comfortable, easy-to-manage experience for anyone.

How long can you trim with the new 40V Power Share™ platform?

The included 20V Max Lithium batteries are designed to provide enough working time per charge to trim up to the average 1/2 acre homesite on one charge. Actual results may vary on various factors, including the density of the grass or weeds you’re cutting, and the age and charge levels of each battery pack.

What is “variable speed throttle control?” Does that mean I can control the speed of the trimmer?

Yes! The 40V Power Share™ Cordless String Trimmer / Edger is equipped with a variable speed throttle control which means you can go from low to GO by controlling how much pressure you put on the trigger. Instead of a switch with high and low settings, your grip controls how much power your trimmer uses.

Features and Benefits

  • BLACK+DECKER™’s electric lawn and garden equipment releases zero emissions in your yard, helping to reduce your carbon footprint

Picture of the Greenworks 40V 113-inch and Amazon review stats

This is the second Greenworks machine in the mid-section category, and we like it a lot. I called Greenworks to check on their customer service, and the lady was very helpful.

The wheel on the trimmer guard makes using it as an edger really effective.  It works great for the price. The interchangeability with other Greenworks G-MAX 40V Li-Ion tools increases efficiency and offers a longer run time for various tools.

The machine we tested lasted about an hour before it needed a recharge – not bad for a 2.0Ah battery.
