Sure, gas weed eaters might have been the way back in the day, but in this day and age battery-powered weed eaters are the way to go. The Best electric weed eaters available on the market came a long way and some can match the performance of their gas competitors.
Battery powered weed eaters are superior in many ways, but they do have a few drawbacks. Here are the advantages and disadvantages that should be kept in mind when buying a cordless weed eater:
When choosing the best cordless weed eater, consider the following:
These days, string trimmers are roughly 15 pounds or lighter. If the garden is large, this should be one of the biggest considerations since any heavier than that would cause anyone to tire easily. You may as well consider a good string trimmer harness to lessen the impact of the weight.
If the yard only has a few weeds and is tiny, then a powerhouse really isn’t needed. However, if there are branches and tough weeds that need to be cut then something that can put some real work in is needed.
Gas trimmers are notorious for being real monsters and effective but over the years the technology of battery-powered models has advanced enough to make them worthy contenders.
Battery life/ run time is important especially when the yard is big. If the battery dies mid-work, it will take time to recharge/replace it and make the work take much longer than it needs to.
Modern lithium-ion batteries are reasonably quick to recharge and they last longer.
Try to get a model with batteries that can be replaced on the go, instead of waiting for them to recharge again.
Straight shaft designs are generally sturdier and can be used for many purposes. They also have more torque and better reach.
Curved shaft designs are typically lighter, quieter and more useful for edging. However, they may be becoming obsolete since straight shafts are extendable.
Cordless models require little to no maintenance. This doesn’t mean that they won’t ever pose a problem.
Their string and head mechanism still need attention from time to time.
This is why reviews are super useful. The experiences of others will help to determine how much trouble the model will be to maintain, especially for beginners.
If getting replacement strings and head for the trimmer seems to be a hassle due to rare strings used or the weed eater head is too unique, then stay away from it. It will be less of a headache in the future.
Go for popular brands that have parts in-store and online, and research universal string and head replacement options.
Many persons don’t end up using a warranty but it is good to have.
Look at it this way, if there is an issue with the product, for instance, it is defective or breaks within the warranty period, there is no out of pocket cost to repair or replace it. That is in the hands of the manufacturer since they make a promise that it will work well for x period.
The type of battery used in the model will help to differentiate it from others. Here’s what will set them apart:
Many battery powered devices use modern lithium batteries because they can store energy for longer all in a small, compact space. Lithium-ion battery can be found in phones, laptops and of course, battery powered trimmers and are lightweight. However, they require protection circuits for safety purposes since they are somewhat fragile.
Nickel metal hydride batteries can give off greater immediate power because they have less resistance. However, they don’t last very long and are not suitable for devices that need power for extended periods, and work poorly in cold temperatures. Nickel Metal Hydride batteries were widely used in laptops and cellular phones.
Despite being cheap to produce, Nickel Cadmium batteries are less commonly used in devices since they have less storage capacity than say Lithium-ion or Nickel Metal Hydride batteries. They also contain toxic materials and are not environmentally friendly. Nickel Cadmium batteries are used in power tools, biomedical equipment, and professional video cameras.
Batteries come with a set of specifications. Anyone who doesn’t know the jargon will be confused about what certain terms mean and if they are good or bad. But we’ve got this covered. Here is a quick rundown of all the important terms related to the batteries in string trimmers.
In the simplest of terms, the battery voltage is the amount of power or strength the battery can provide.
Think of an electrical circuit as a water turbine system. The maximum capacity of the pipes may be x, but that doesn’t mean that there will always be x amount of water in the pipes.
When there is more x amount of water in the pipes, the turbine at the end can turn faster since it has more power being driven towards it. The amount of water that reaches the pipe is dependent on the drain that connects the pipe and the turbine. If the drain is big, then more power can be driven at once. However, if it is small then the turbine won’t turn as quickly.
In other words, voltage is the water pressure.
Ampere hour can be described as how much charge the battery can store measured by time, or in the case of the water system, the speed of flow. For instance, 1000 gallons an hour, in a 10,000-gallon tank would take 10 hours to empty.
To measure the capacity of a battery, we check how many hours we can get out of it until it is completely drained.
Run time refers to how long the battery will take to run out from the time it is being used until it stops giving out power. This is an important consideration especially if the yard is big and it will take a good amount of time to complete the work.
Do not get this confused with charge time which describes how long the battery takes to be fully charged after it is drained of energy.
Cross compatibility is a plus since it can help to save money, especially when power tools are of the same brand. Imagine having to get a brand new battery in the middle of yard work without being able to borrow one from another tool?
Brands typically have their own set of specifications in terms of connectors and voltage, therefore interchangeable batteries can only be shared with the same brand and same system tools. For example, Worx has the MAX and PowerShare systems, GreenWorks has G-MAX and so on.
Breaking a line can be the most annoying and inconvenient thing to happen, especially when the work is nearly done or when there are many other things on the agenda for that day.
To avoid breaking a line, check the trimming path. Are there any rocks or debris? Get rid of them before turning on the trimmer. If the brush is too thick for the weed eater, do not attempt it.
For regular cutting, approach from the edge and ease into the work slowly. The tip is the most effective part of cutting.
Avoid curbs, pavements, the edge of buildings and other obstacles that can cause the line to snap. Approach them with caution from the side or do it manually. Better safe than sorry right?
In case the line is broken, there is no need to cry over spilt milk. Check out our guide on how to re-string the trimmer.
When choosing the best battery powered weed trimmer, it is best to read a number of reviews and get feedback from others since they can help to make an informed decision.
In our opinion, the Worx WG163 model should be the most popular weed eater on this list. We highly recommend as it is a good compromise between performance and price.
Even though the Milwaukee is the most expensive, it does an awesome job and is top quality, thanks to its great design and powerful battery system.
