You're free of the cord! You're able to move around without restriction.
Cordless electric hedge trimmers offer freedom from gas and oil, but also freedom from a cord.
They're the best of both worlds, and they're also much quieter than gas models.
Cordless trimmers are a great option for those who want a cleaner, quieter experience with easy start-up.
When choosing a cutting width, we recommend you choose a blade equal to the size of your hedges. Measure the depth/width of your hedge and choose a blade equal to or greater than the size of your hedge.
This will enable you to make smooth sweeps across the tops and sides of your hedges without missing any spots, making the surfaces smooth and level.
But don't get a blade that's unnecessarily large. The larger the blade, the heavier the unit will be. It's always best to keep your hedge trimmer as light as possible to improve handling and avoid fatigue.
Batteries come in Lithium Ion and NiCad, however NiCad batteries are going away. While NiCad batteries tend to be more durable, Lithium Ion batteries are smaller, lighter weight, and have virtually no self-discharge.
Remember batteries can only hold so much power at a time. A single battery can keep you running for approximately 30-40 minutes depending on the voltage and the charge. If you have a lot of trimming to do, it may be in your best interest to get yourself a backup battery so you can finish your job.
