Top 10 Battery Powered Weed Eaters
How to choose the best battery powered weed eater
Choosing the best battery powered weed eater might seem pretty easy. However, this is not always so. There are certain things that have to be considered. These are what distinguish the best from the rest. Before you settle on any weed eater, consider these features.
Power output and battery
The power output of any battery powered weed eater is what sets it apart from the rest. It is what makes you accomplish the particular task that you want. The battery in the weed whacker should be high voltage to trim any type of grass no matter how tough it is.
The best battery powered weed eater has a long-lasting battery life and delivers the same high powerful performance that you need. A battery that needs frequent charging will be a huge inconvenience if you intend on mowing a large piece of lawn. Nickel Cadmium batteries are known to require frequent charging, unlike their Lithium-ion counterparts.
Cutting swath diameter
Trimmers with a larger cutting diameter are more efficient in their use of torque and keep the cutting speeds high. A longer cutting line enables you to perform the work faster than a shorter one would take.
The cutting diameters range from 13 inches to about 16 inches. This length if increased beyond certain limit weighs down the trimmer. This uses more power and drains the battery faster. You are advised not to remove the guard to increase the cutting swath.
It’s not like it is all doom for smaller cutting diameters. They still find use in areas with a lot of obstacles. The short diameter is easy to maneuver around rocks, fencing and lawn furniture.
Electric weed eaters are generally quieter than the gas-powered types. However, even the electrical ones differ in terms of the amount of noise they produce. The best battery powered weed eater should produce the least amount of noise. This should be the same no matter the mode of operation whether in Eco or full throttle modes.
The lithium-ion battery-powered string trimmers produce the lowest noise levels. This enables you to go about your work early in the morning or late at night whenever it is most convenient for you. The neighbors will not complain of any disturbance as the only noise produced is that of grass being whacked. Check the decibels ratings of the trimmer before you buy it.
As you tend to your lawn, you need the least weight possible from the trimmer to get more work done in a day. The low weight should not sacrifice on the power you need. The weed eater should, therefore, be easy to carry around the lawn.
Besides being lightweight, the trimmer should be strong. Slight knocks and bumps should not damage it. Again, lithium-ion batteries will be lighter than cadmium batteries.
The best battery powered weed eater should have the provision of being customizable to your specific needs. The handle and heights should be adjustable to positions where it is most comfortable for your use.
An uncomfortable handle can be really tiresome when you are out there in the sun. A shorter or longer handle makes the tool too difficult to use. It may be quiet or very powerful, but if it causes you pain when using it, then it is not worth it.
String feeding system
The ease of feeding a new line to your trimmer is what makes it the best battery powered weed eater. This reduces time wastages when you need to introduce a new line of cutting. Different trimmers have varying feeding systems.
There are those with the bump loading strings. When you need more cutting lines, you bump the head of the trimmer on the ground. This releases more line. Then there is the automatic string loading, which continuously replenishes the line when need be.
Any trimmer will be able to clean up any lawn; some have additional features for a professional look in your yard. Weed eaters with straight shafts and a rolling feature enable you to give the lawn a neater edge. You simply roll it along the edge as it trims the grass.
Varying the speed of the trimmer should also be a feature to look for. A variable speed trigger allows you to conserve power when trimming on light grass. You then increase the speed on denser patches of weed and grass.
