10 Best Battery String Trimmers 2025 in the United States

The Worx String Trimmer Cordless GT3.0 is a versatile tool that functions both as a string trimmer and an edger, making it handy for various lawn care tasks. It operates on a 20V battery system and comes with two batteries, ensuring you have extended runtime. The cutting swath is 12 inches, which is decent for small to medium-sized yards. At a weight of 5.3 pounds, it is relatively lightweight and easy to handle, especially with the rubberized wheels for support and guidance.

The head tilts 90 degrees, which is useful for trimming on slopes and hard-to-reach areas, and the adjustable spacer guard helps avoid damaging your plants and ornaments. The Command Feed spool system allows for instant line feeding, which is a convenient feature, and the free spools for life offer cost savings in the long run. However, the line diameter is 0.065 inches, which might not be suitable for very tough weeds. Additionally, while it provides a no-load speed of 7600 RPM, users with larger yards or heavy-duty requirements might find the battery needing frequent recharges.

Assembly is required, which might be a minor inconvenience for some users. This trimmer is ideally suited for homeowners with small to medium-sized lawns who value versatility and ease of use.

The Worx String Trimmer/Edger/Lawn Mower 3-in-1 GT Revolution is a versatile garden tool that combines a string trimmer, edger, and mini lawn mower. It operates on 20V batteries, which are included in the package, along with multiple accessories such as trimmer spools and a charger. While the 12-inch cutting swath might be slightly smaller than some other models, it is sufficient for typical residential use. The product's relatively light weight of 4.04 pounds makes it easy to handle, even for extended periods.

One of its standout features is the automatic fresh line system, which allows you to quickly add more line with the push of a button, reducing downtime during use. Additionally, the trimmer offers excellent adjustability with 7 handle adjustments and 6 rotating head settings, making it comfortable to use in various positions and reach difficult areas. The motor runs at 7600 RPM, providing strong performance for most garden tasks. However, the 5-hour charging time might be a drawback for users needing quick turnaround times.

This makes the Worx GT Revolution well-suited for homeowners looking for a multi-functional garden tool with flexible usage options and easy handling.

The Greenworks 60V 16” Brushless Cordless String Trimmer is a solid choice for those seeking a battery-powered tool for maintaining lawns. With its 60V power and 2.5Ah battery, it provides up to 65 minutes of runtime, which should be sufficient for most residential trimming tasks. The brushless motor is a notable strength, offering enhanced power and longer motor life compared to traditional models. This trimmer features a 16-inch cutting swath, making it efficient for medium to large areas, and the dual line bump feed system is designed for user convenience, allowing quick reloads.

Weighing in at approximately 11.6 pounds, it's relatively lightweight, which might appeal to users who need to work for extended periods without experiencing fatigue. This is particularly beneficial compared to gas-powered alternatives, often heavier and harder to manage. Additionally, the trimmer's compactness aids in maneuverability, especially around sidewalks, driveways, and flower beds.

However, there are a few considerations to keep in mind. While the battery life is decent, it might not be adequate for larger properties without recharging. Also, the inclusion of only one battery could be limiting if continuous work is required, as users would need to wait for recharging. As with many battery-powered tools, the initial investment might be higher than gas counterparts, though it compensates with ease of use and lower operating noise.
