Cordless hedge trimmers have closed most of the gap with gas models on cutting power, while cutting out the fumes, cord-dragging, and maintenance.
We compared blade length, cutting capacity, and battery ecosystem compatibility, since a trimmer that shares batteries with tools you already own is worth a lot.
What to Look For
- Blade length: 20-22 inches handles most residential hedges; go longer only for tall, wide privacy hedges.
- Cutting capacity: 5/8-inch branch capacity covers most overgrown shrubs — thicker growth needs loppers, not a trimmer.
- Battery platform: If you already own 20V tools from a brand, a compatible bare trimmer saves money over a full kit.
- Rotating handle: A 180-degree rotating rear handle makes vertical and angled cuts far less awkward on your wrist.

Frequently Asked Questions
How thick a branch can a cordless hedge trimmer cut?
Most residential models handle up to 5/8-inch branches — anything thicker should be cut with loppers first.
How long does a hedge trimmer battery last per charge?
Expect 30-60 minutes of continuous trimming on a standard 20V battery, depending on how dense the growth is.
Is a rotating handle worth it?
Yes for taller or wider hedges — it lets you cut vertical faces and angled tops without twisting your wrist the whole time.
