Although interchangeable, the batteries have a short lifespan of up to 30 minutes or so. This is obviously not enough time to fully trim and edge a large yard. Some reviews show that this weed only lasts about 20 minutes before you need to recharge it again.

Buyer’s Guide: How to Choose the Best Battery Powered Weed Eater

If the sheer variety of options available to you makes you feel confused or overwhelmed, here are a few factors you should consider to help narrow down your options and get you closer to a decision.

1)- Charging Time

To operate a cordless weed eater, you need a fully charged battery and this can take time. This means you can’t use it while charging.

That’s why people are looking for fast-charging units that will help you get the job done faster. For best results, look for a unit that takes 40 to 60 minutes to charge so it won’t take the whole day to mow your lawn.

2)- Battery Power

It used to be that gas-powered trimmers were considered better than battery operated models. But, the convenience and efficiency offered by cordless units are unmatched. Most modern models operate like the best gas weed eaters, except without the wallet-sucking and gas-guzzling performance.

Note that cordless units measure power according to volts or V for short. The most common trimmers are 20 and 40 volts and the one you pick depends on the condition and size of your yard.

3)- Battery Life

Lithium-ion batteries come highly recommended for their durable construction and long runtime. They offer quick charging times and if you have a small yard then a single charge is often enough to cover an entire lawn.

4)- Dual-Mode

Most cordless trimmers are optimized for flexibility and work as edgers as well. This means you can twist the head in order to trim the edges and other difficult to reach places. The dual-mode unit is for anyone who wants an immaculate finish and the LCC222 is a great example of this.

5)- One String vs Two Strings

The average garden only needs one line. Dual lines mean more cutting work, but they also make it easier to cut through dense shrubs, tough grasses, and thick weeds. The option most suitable to your yard will depend on its condition.

6)- Weight

Most cordless weed eaters weigh very little and you can trim your entire yard without feeling too tired or worn out before you’re even finished. It’s also much easier to use and allows you to cover large surface areas for a shorter amount of time.

7)- Warranty

While most people aren’t going to use or take advantage of the warranty, it’s still nice to have just in case something happens to the machine.

Most good manufacturers offer a warranty of one to three years, starting from the date of purchase. This warranty typically covers the cost or replacement or repair in case the machine breaks. You may even get a refund in certain situations, granted the damage meets the criteria for such.

It’s advisable to store your receipts and warranty documents in a safe place just in case you end up needing it in the long run. It might save you some money.

Types of Weed Eaters

Early weed eaters ran on gas but thanks to technological advancement we now have both cordless and corded versions. But, is a battery-operated model the best way to go for everyone?

There’s no definitive answer to this question but the following factors might help you answer it for yourself.

I- Gas Weed Eaters

Gas-powered weed eaters are lauded for their powerful performance and fast trimming ability. That’s because the powerful motor leads to powerful performance and all you have to do is pull a cord to activate the engine. However, the most attractive aspects of a gas eater include the fact that it can trim large swathes of grass and it’s fully portable.

Gas weed eaters are quite noisy and weighty, which means you might get tired lugging them around after a few hours. Over time, you might also find that it’s quite difficult to start your gas trimmer, especially if you don’t put a lot of effort into its maintenance. Plus, you have to deal with the fumes and air pollution it emits.

II- Cordless String Trimmers

Cordless string trimmers have come a long way since the first units were created, to the point that the latest models operate on a very high-performance level.

They’re no longer the fragile and weak machines they used to be and offer a runtime of up to 60 minutes. This is in stark contrast to the 10 to 15-minute runtime of past models.

Battery-powered weed eaters are also easy to use, highly portable and lightweight. They also work quietly so you won’t annoy your neighbors when trimming your lawn.

III- Corded Weed Eaters

Corded weed eaters are very popular because they operate on electricity and don’t emit any hazardous fumes. But they are lightweight and powerful enough to help you trim your lawn efficiently. Most models are flexible enough so that you can convert them into an edger if you like.

But, you can only use a corded weed eater for a limited distance because the cord can only go so far. The wire can also get tangled on shrubs and trees, thus taking longer to complete your work.

Battery Powered Weed Eater Advantages

There are many benefits to using a battery-powered weed eater. Read on for a few of them to help you figure out if it’s a suitable option for you.

Doesn’t Require Much Maintenance

Gas-powered weed eaters require a lot of maintenance, this is no secret. But, battery-powered models are actually very low maintenance because all you have to do is press a button to get it working and recharge it in between.

It’s Extremely Easy to Handle

If ease of use is important to you, then you should definitely consider battery-operated weed eaters, because they’re lightweight and highly portable. Most models weigh a few pounds which means you can work with them for a few hours without feeling worn out.

Doesn’t Make a Lot of Noise

Battery-operated weed eaters work noiselessly because they don’t contain a combustion engine.

You Can Easily Store It Anywhere You Want

Due to their lightweight and portable construction, battery-operated trimmers are super easy to store. This makes them ideal for users that only have limited storage space.

It’s More Affordable

Without the need for gas or oil, battery-weed eaters are cost-effective and energy-efficient. They won’t register a single tick on your monthly gas bill, and they will reduce your carbon footprint as well when compared to using corded or gas-powered models.

You Won’t Have a Hard Time Using It

To start a gas-powered trimmer, you have to go through a long and arduous process. On the other hand, battery-operated models are super easy to work with because all you have to do is press one button and it’ll start working instantly. They’re so easy to use that even a novice can get it started without any issues.

Type of Battery

Weed eaters typically use the following types of batteries:

I- Lithium-Ion

This type of battery is really popular because it’s not only powerful but it also offers decent energy storage. That’s why devices like laptops, phones, and power tools use lithium-ion batteries.

II- Lead Acid

Lead Acid batteries are commonly used in four-wheelers, ride-on mowers, tractors, card and other types of vehicles. This gives you an idea of their power and it helps that they’re resistant to most weather conditions and discharge, while offering higher cold-cranking amps.

III- Nickel Cadmium

Nickel Cadmium batteries are mostly utilized in household applications and include AA and AAA models. They don’t have a lot of storage space but they’re much cheaper than lithium-ion and Nickel Metal Hydride counterparts. They’re also resistant to extreme temperatures and you’ll need to discharge them at least once a month.

IV- Nickel Metal Hydride

These batteries offer less resistance which compromises their overall lifespan. They’re perfect for applications like high-lumen flashlights and flash photography.

How to Deal with Rechargeable Batteries?

The great thing about rechargeable batteries is that there are measures you can take to prolong their lifespan.

What You Should Do?

You Should Use the Battery Regularly

Using a battery for long periods of time obviously drains it faster and reduces its overall lifespan, but so does store it in a den for a whole season.

That’s why it’s recommended to use your weed eater at least once a week or at least turn it on so that it’s active. You should also avoid placing it in the charger while storing it for the winter.

Always Make Sure the Battery is Charged

Old wisdom told us that you have to wait until your battery was completely drained before you recharge it because that would prolong its lifespan. But, newer batteries actually require the opposite strategy.

They’ll last longer when you start charging the device at 70% or so. It’s worth noting that NiCd batteries feature a “memory effect” which tells you when you’re close or far from full capacity and you only need to discharge them once a month.

Ensure the Battery is Charged, Full

You should wait until the battery is fully recharged before you remove it from the charger. Your charger should come with an indicator light that tells you when it’s nearing completion.

Put Your Batteries in a Dry Place

While you probably shouldn’t store your battery in the refrigerator, you should look for a dry and cool area to store it in. Temperature extremes and humidity are not the best environments for any type of battery.

Make Sure You Store Them Properly


Most rechargeable batteries come encased in a cushioned bag or carrying case. However, it’s important to replace the plastic cap it comes with when it comes time to store the battery for the winter. That’s because a fresh cover will improve your ability to protect it from breakage and moisture damage.

Adjust the Settings

Be sure to familiarize yourself with the features and functions offered by your weed eater so you know which speed works best for longevity and performance.

High power settings are not recommended because they’re more likely to drain and damage the battery faster. But, if you have to use them just make sure to turn down the toque to extend your battery life.

What You Shouldn’t Do?

Don’t Drain the Battery

You probably shouldn’t deep drain your battery all the time but this might be what it takes to completely mow and trim your lawn. But, doing so will shorten the battery’s lifespan thanks to damaged poles. For best results, be sure to recharge your battery when you notice a lag in performance and deep drain your NiCd batteries at least once to prevent reduced capacity.

Don’t Overheat the Battery

You can easily overheat a battery by storing it in the wrong place. Avoid placing your battery in a place that’s prone to overheating as this may cause an explosion. If your battery gets too hot for you to touch it, try to move it to a cooler spot and only check it when it has cooled down.

Don’t Overcharge It

You should avoid overcharging a battery as that can shorten its lifespan and cause considerable damage. Look for one that comes with a charger that will automatically switch off when it’s done charging or just look out for the indicator light so that you can pull the charger out when it’s “full.”

Don’t Get It Wet

This one should be a no-brainer because water and electricity have never been friends. But, it’s worth mentioning that if your battery happens to get wet, take measures to dry it and remove all moisture.

Frequently Asked Questions

Why go with battery-powered weed eaters?

Older, gas-powered string trimmers can cause pollution and aren’t eco-friendly at all. They’re not cost-effective either and are quite noisy.

Rechargeable weed eaters, on the other hand, are very eco-friendly, cost-effective, and don’t make much noise.

How to remove the battery from the weed eater?

Every weed eater comes with an unlocking lever close to the battery. All you have to do is rotate or pull on this lever to remove the battery without directly touching it. It’s a very straightforward and uncomplicated process.

How to figure out the battery life?

Most weed eater batteries last for about 30 to 90 minutes. This depends entirely on the Ampere-hours (Ah) that can go from 1.3 to 5 Ah. This is known as autonomy and each manufacturer indicates this important detail on their website or product sheets.

But, it’s worth noting that poorly made models are unable to retain their autonomy and it will wane over time.

Is there any safety equipment required when using string trimmers?

A traditional battery powered weed eater is powerful enough to shred any obstacle in its way, from the smallest blade of grass to actual glass. That’s why you should always wear protective gear when using your unit. This includes sports shoes, gloves, safety glasses and long, tactical and durable pants.

A battery operated weed eater doesn’t make any noise, so you won’t have to wear any mufflers or noise-canceling headphones. But, you’ll need these for gas-powered weed eaters.

Is it possible to use other cutting heads?

You should follow the manufacturer’s recommendation when it comes to the way you use the cutting heads. You should avoid using differently sized blades and wires as that could incredibly damage the machine.

Final Thoughts

The thought process of choosing a weed eater can be long and taxing. This is not the kind of purchase you want to keep making, so you need to think carefully before you make your final choice. You want to find a weed eater that’ll last you for more than a couple of years and will perform efficiently throughout.

We searched far and wide to find out the best battery powered weed eaters. As you can see, battery powered weed eaters come with a number of benefits. They’re cordless, cost-effective, eco-friendly, energy-efficient, easy to assemble, and easy to use. They basically tick all the boxes of what you’re looking for in a trimmer.

Just make sure to use the right battery with your weed eater otherwise you might find yourself recharging it every 20 minutes. Look out for a unit that offers considerable run time, maneuverability, and solid constriction. Also, it’s important to store the battery properly and practice the correct maintenance measures to extend its lifespan.

If you still can’t decide which weed eater you should choose out of the options reviewed in this article, we highly recommend the MILWAUKEE M18 FUEL String Trimmer.
