Buyers Guide: Considerations To Make When Choosing a Battery Powered String Trimmer

Choosing a string trimmer in the market can be overwhelming, given the numerous trimmer options. For this reason, we drafted a guide with the best considerations to make to get your perfect weed eater for your landscaping needs. Keep reading to learn about them.

The Battery Capacity

When choosing a battery-powered string trimmer, the number one consideration is the power holding capability of your shortlisted string trimmer’ batteries. You can determine the capacity of a given string trimmer battery by looking at its:

Type

In most cases, battery-powered string trimmers can run under nickel-cadmium or lithium-ion batteries. The latter has a higher power holding capacity than the nickel-cadmium batteries. That implies that the weed eaters bearing lithium-ion batteries are the best buy. However, the high quality comes at a price. 

If any of your subject trimmers have a different battery model from the two above, consult about battery life before committing your money.

Pro tip: Always go for a trimmer whose batteries have the longest life.

Voltage

Battery voltage refers to the amount of power it has to drive the motor of the weed eater. Most cordless string trimmers run on 20v batteries, while others use as high as 60V. We recommend you to go for a higher voltage number if you have an extensive lawn.

Charging Time/ Extra Batteries

When looking for a trimmer, you should go for the one with fast-charging batteries to minimize inconveniences while on the lawn. Going for a trimmer with extra batteries is also a plus, as the spare batteries can help you clear a significant percentage of your lawn before you head for an additional charge. 

Attachment-Friendly

As a landscaping enthusiast, you are probably aware that it can take various lawn care tools to maintain a well-manicured lawn. 

However, the good news is that you can cut down the cost of buying separate equipment by getting an attachment-friendly string trimmer. 

For instance, some spring trimmers can easily convert to edgers, blowers, etc., to save your pocket and give you hassle-free storage. We highly advocate for such.

The Cutting Width

The cutting width of a weed eater depends on the width of its head. A wide head means a wide cutting width and vice versa. You can find the trimmer head widths going as low as 10 inches and as high as 18 inches in the market. 

While the wide cutting widths are ideal for large lawns, the smaller heads are ideal for confined spaces like rocky areas. We suggest that you assess your cutting needs to pick a trimmer with the appropriate cutting width.

Noise Level

The fact that battery-powered trimmers are less noisy than their gas-powered counterparts doesn’t mean they are quiet. They, too, make a given level of noise during their operation. 

Unfortunately, most manufacturers won’t indicate the noise level of their trimmers. The best way to tell whether a given trimmer is noisy or not is by asking past customers about its efficiency. 

You can get customer insights from reliable lawn care websites or the brands’ social media pages.

Weight

When looking for a weed eater, picking something that won’t strain your hands and back when cutting on the grass makes sense. That means going for lightweight string trimmers like the ones we have included in our review section.

Maneuverability

Another essential factor to consider when buying the trimmer is how well it is adapted to give you hassle-free cutting on all types of terrain. That may mean focusing on factors like optimal weight distribution, adjustable handle, adjustable height, edging wheels, weight, and other factors that may enhance the mobility of the trimmer around the lawn.

Price

Typically, the prices of most trimmers range between $ 60 to $ 400 depending on their versatility and ease of use features; while most versatile trimmers come with high prices, not all highly-priced string trimmers are of high quality. Some rogue manufacturers may charge high prices for their counterfeit products to mislead customers.  

For this reason, we suggest that you factor in the considerations in the above sections before moving to price. Remember to pick a trimmer whose price falls within your budget.

Frequently Asked Questions About Battery Powered Weed Eaters

Below are answers to various questions people have asked about battery powered weed eaters.

Do battery powered weed eaters work?

Yes. Battery-powered weed eaters deliver fast and precise cuts to give you a well-manicured lawn. Like the gas-powered trimmers, they feature an accelerator that initiates the spinning of the cutting head to make cuts.

How long does a battery powered weed trimmer last?

A typical battery-powered trimmer lasts between 25 and 40 minutes per charge. However, anecdotal reports from some users indicate that the batteries can last for more than 60 minutes when the trimmer is operating on a low-speed setting.

If you want to enjoy longer cuts and your battery is not promising, you can buy spare batteries for replacing the ones that run out of juice while in the field.

How many volts does a weed eater need to run efficiently?

The optimal number of volts for running a trimmer depends on its type. For instance, the low-voltage battery trimmers run on 18 to 36v batteries, while the high voltage weed eaters run on 40v and 80v batteries. 

What does a brushless motor mean in a battery-powered weed eater?

A brushless motor means a motor without brushes. And, being brushless signifies a durable motor optimized to utilize battery power for a longer time than their brushed counterparts.

How does the automatic feed spool in a trimmer work?

The feed spool detects and replaces the fading cutting lines to give you consistent cuts. It relieves you from the burden of feeding the cutting lines manually.

So, What is the Best Battery Powered Weed Eater?

The best battery powered trimmer is the one that helps you achieve your lawn cutting needs efficiently. We recommend you pick a versatile trimmer with numerous ease of use features like the examples in our top seven selections.
