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 EGO Power+ ST1502SA 15-Inch 56-Volt Cordless String Trimmer is a strong contender in the battery-string-trimmers category. One of its standout features is the high battery voltage of 56 volts, which promises powerful performance. The included 2.5Ah battery capacity should provide reasonable run time for most home users, though heavy-duty users might wish for an extra battery. The 15-inch cutting swath is impressive, allowing you to cover more ground quickly, reducing trimming time. At 7.4 pounds, it sits in a manageable weight range, although some might find it a bit heavy for extended use.

The adjustable features, like the variable speed control and rapid reload head, enhance usability by providing customization depending on your specific needs and making line replacement straightforward. The dual-feed spiral twist line and brushless motor ensure efficient cutting and longer motor life, which is a significant plus. The fan-cooled charging system and included charger that supports all EGO batteries are added conveniences that help in battery maintenance and compatibility across the EGO tool range. A 50-minute full charge time is relatively quick.

However, the trimmer might feel bulky due to the split shaft design, which can make storage easier but might affect balance during use. The IPX4 weather resistance is a useful feature for outdoor work. The warranties are generous, providing peace of mind for tool and battery longevity. While it ticks many boxes for performance and convenience, it might be on the higher end of the price spectrum. This trimmer is best suited for homeowners who require a reliable and powerful tool for regular yard maintenance and appreciate the flexibility of battery-powered equipment.

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.
