How we test
To find the best battery string trimmers, I tested each model in real-world conditions over several weeks. I evaluated cutting power on grass and weeds of varying thickness, battery runtime under continuous use, and how comfortable each trimmer felt during extended sessions. I also considered charging time, build quality, and any unique features that set a trimmer apart.
I selected five trimmers that represent the top performers across different price points and use cases. Each trimmer was used on the same test plot to ensure fair comparison. I did not accept free products or compensation from manufacturers; all trimmers were purchased or borrowed from retailers.

What to look for
Battery System
Consider the battery platform you already own. Sticking with the same brand saves money on extra batteries and chargers. If starting fresh, look for a system with multiple tools available.
Cutting Swath and Power
A wider cutting swath (14-16 inches) covers more ground quickly but requires more power. For light trimming, 12-13 inches is sufficient. Brushless motors offer better efficiency and torque.
Weight and Ergonomics
Heavier trimmers can be tiring. Look for adjustable handles, telescoping shafts, and balanced designs. Consider where the battery is mounted (rear or front) as it affects balance.
Line Feed Mechanism
Bump feed heads are common and reliable, but automatic feed heads save time. Some models offer dual-line heads for faster cutting. Check how easy it is to reload the line.
Our verdict
For most homeowners, the EGO Power+ ST1623T offers the best combination of power, runtime, and comfort, making it my top pick for 2026.
FAQs
Runtime varies by model and battery capacity. Most trimmers run 30-60 minutes under normal use. Larger batteries (5.0 Ah or more) can last over an hour. Actual runtime depends on grass thickness and speed setting.
Yes, many trimmers can be rotated to an edging position. Some have a dedicated edging function or an attachment. Check if the trimmer head pivots or if an edger attachment is available.
Modern battery trimmers, especially 40V and 60V models with brushless motors, can match or exceed gas trimmers in power for most residential tasks. However, for extremely thick brush, gas may still have an edge.
