Battery + Motor: A rechargeable lithium-ion battery powers an electric motor, which drives the cutting blades. No need for fuel, oil, or plugging in during operation.
Cutting Blades: Most cordless hedge trimmers use dual-action blades (blades that move back-and-forth on both sides) — this ensures cleaner cuts and reduces vibration compared to single-blade designs.
Safety & Controls: Many have a dual‐hand safety switch (both front and rear handles) so the blades only spin when you intentionally grip both — avoiding accidental starts.
Ergonomics: Adjustable or rotating handles, soft-grip surfaces, and balanced weight distribution make the tool comfortable to use, even overhead or for extended trimming sessions.
