What to Consider When Choosing the Best Cordless Trimmer

Best Battery Powered Trimmer

When shopping for a string trimmer, keep in mind yard size, how often you’ll be using the tool, and who will be doing the actual trimming. The following key considerations will help you choose the right model for your needs.

Trim Width

Trim width, also called “swath width,” indicates how wide a path the trimmer will cut through weeds in a single pass. Many models on the market today feature swath widths of 10 to 18 inches. The wider the width, the more power the trimmer must-have, which often means the trimmer will be heavier because it will require a larger, more powerful battery.

Battery Type

Running a string trimmer requires a hefty dose of power, and most of today’s trimmers run on rechargeable lithium-ion (Li-on) batteries, but a few accept nickel cadmium (NiCad) batteries. Li-on batteries are more powerful but NiCad batteries are less expensive (an average of $70 to $125 less). Li-on batteries also are smaller and hold a charge longer.

NiCad batteries suffer from “memory effect,” meaning if the battery is used before it has fully charged—or if it’s recharged before its power depletes—it will remember the charge levels and won’t hold a longer charge in the future. If you opt for a trimmer that has a NiCad battery, you’ll get the best results if you let it charge fully before use and drain completely before charging. For most users, a string trimmer with a Li-on battery will be the best choice.


Along with battery type, consider how much operating power the battery has, which is measured in volts. Today’s rechargeable string trimmer batteries average from 18 volts up to 60 volts of power. More powerful batteries at the high end often are intended for commercial use and can cost $200 or more per battery. The string trimmers in this category often sell without a battery (or battery charger), which the user must purchase separately. Batteries at the lower end are sufficient for powering many string trimmers and one or two batteries often come with the purchase of a trimmer.

Ease of Use

Right from the start, cordless string trimmers are simpler to operate than gas-powered trimmers because there’s no fuel to mix or time and energy spent yanking a pull-cord. Beyond that, a couple of additional factors will help determine how easy the tool is to operate.

  • Auto feed vs. bump feed vs. button feed: This pertains to how the tool releases an additional trimming line as it becomes frayed and broken during use. The standby is a bump feed where the user bumps the bottom of the trimmer—the area where the spool attaches—on the ground to release a few inches of line. Some newer models feature an auto-feed sensor that gauges the length of the string and releases more when needed. Still, others feature a push button that releases more line. Auto and button feeds eliminate the need to bump the spool, which can reduce the risk of damage if bumped too hard, but many commercial-type trimmers still use bump feed because it’s quick and easy.
  • Curved shaft vs. straight shaft: Some stringers feature a straight shaft that runs from the head of the trimmer to the end while other models feature a distinct curve in the shaft about two-thirds of the way down. Curved-shaft trimmers often are easier to operate since the spool end already rests at a handy angle for cutting weeds. Straight shaft trimmers often accommodate interchangeable tools, such as a tree trimmer head, which can be swapped out depending on what you’ll be trimming. In general, straight shaft trimmers work better for users at least 6-feet tall, while shorter users will appreciate curved shaft trimmers.


Battery-powered string trimmers have a distinct advantage over gas-powered trimmers when it comes to noise pollution. Gas-powered trimmers are moderately loud, emitting an average of 90 decibels—or about the same loudness that a motorcycle makes when it passes by at a distance of 25 feet. By contrast, a cordless string trimmer emits approximately 77 decibels, which is comparable to the loudness of living room music.
