10 Best Battery String Trimmers 2025 in the United States

The EGO Power+ MHC1603 is a versatile battery-powered string trimmer kit that stands out with its 56-volt, 4.0Ah lithium-ion battery, offering solid runtime—up to 45 minutes with the trimmer attachment and even longer with the edger. The 16-inch cutting width is suitable for most residential lawn care tasks, balancing efficiency and control. Its carbon fiber shaft keeps the overall weight moderate at about 34 pounds for the entire kit, which is reasonable considering it includes multiple attachments and a battery, but the tool alone will feel lighter in use. A highlight is the POWERLOAD system, which makes reloading the trimmer line quick and easy with just the push of a button, saving you time and hassle. The edger attachment includes a depth adjustment feature, allowing for precise edging up to 3 inches deep, which is handy for neat lawn borders.

The power head offers two digital speed settings and a safety lock, adding user control and peace of mind during operation. Weather resistance (IPX4 rating) means it can handle light rain, increasing convenience. While the kit weight might be a bit heavy for prolonged use if you prefer ultra-light tools, and assembly is required which could be a minor inconvenience for those wanting a plug-and-play experience, this kit’s price point and the included charger and battery make it a good value for those seeking a reliable, multipurpose tool with long battery life and easy maintenance.

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 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.
