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 Greenworks 60V 16" Brushless Cordless String Trimmer is a strong contender if you're looking for a powerful, cordless lawn tool. Its 60-volt battery with a 4.0 Ah capacity provides excellent power and decent runtime, allowing you to trim for longer periods without frequent recharges. The brushless motor offers better efficiency and torque compared to many gas-powered trimmers, but without the noise and fumes, which is great for quieter, eco-friendly yard work. The 16-inch cutting swath strikes a good balance—wide enough to cover ground quickly while still being manageable around tight spots. At 18.7 pounds, it’s on the heavier side for a battery trimmer, which might be tiring if you have a large area or prefer a lightweight tool. You’ll appreciate that it comes with a battery, charger, and even a spool, so it’s ready to go out of the box. Its compatibility with over 75 other Greenworks 60V tools might be a bonus if you plan to expand your cordless garden equipment.

The 4-year warranty on both the tool and battery adds peace of mind. This trimmer is suited for homeowners who want a strong, quieter alternative to gas models and value long battery life. If you prioritize light weight or highly adjustable features, you might want to compare with other models.

The EGO POWER+ String Trimmer is a battery-powered option that offers some notable strengths for tackling weeds and grass. It comes with a robust 56V 4.0Ah battery which provides a good balance between power and running time, making it suitable for medium to large gardens. The 16-inch cutting swath allows for efficient trimming, reducing the time you spend on yard work. Its lightweight design at 7.5 pounds, coupled with a telescopic carbon fiber shaft, makes it comfortable to handle, accommodating different user heights for enhanced ergonomics.

The trimmer is equipped with a high-efficiency brushless motor, which is known for extending the tool's life and delivering consistent performance. The professional-grade, dual line spiral-twist 0.095-inch line ensures precise cuts, while the digital 2-speed selector lets you adjust the power depending on your trimming needs. Additionally, the weather-resistant construction provides durability and reliability, even in diverse weather conditions.

The POWERLOAD and LINE IQ features offer convenience, automatically feeding the line as needed, reducing manual adjustments. The trimmer is compatible with all EGO 56V ARC Lithium batteries, which is a plus if you own other EGO products. Despite these strengths, assembly is required, which might be a minor inconvenience for some users. Also, while the trimmer is a top choice within its category, ranking #1 in string trimmers, the price may be higher compared to other models, reflecting its professional-grade features. Nonetheless, with a 5-year tool warranty and a 3-year battery warranty, it offers peace of mind for long-term use.
