How To Choose A Battery Powered Cordless Weed Eater?

Even if it might seem easy to choose an electric cordless weed eater, the things are not quite that simple. There are a series of things to consider before buying a cordless weed eater, beginning with the common considerations regarding the purpose of use and versatility.

Just like in the case of the corded or gas-powered models, you should consider the:

  • Weight;
  • Level of noise;
  • Cutting width;
  • Ease of handling;
  • Versatility.

But in addition to these factors, probably the most important thing to consider is the battery.

On the market, you will be able to find a wide range of cordless weed eaters, with batteries ranging from 12 volts to about 56 volts. Depending on the scope of use, you should choose a battery with a lower or with a higher voltage.

If you have a small lawn with a thin type of grass, then a 12-volt battery could be an excellent choice. A 12-volt battery is also a great choice for the beginners in the field of lawn care. The 18-volt and 20-volt weed eaters are also typically designed for residential use, but they are ideal for larger lawns and thicker types of grass.

If you have a really large lawn, of 1 acre or more, than it makes sense choosing a more powerful battery, of 36 volts or more. You should also look for a higher voltage if you are a lawn care professional considering to invest in an ecological tool.

However, if you are just a homeowner looking for the perfect tool to maintain your lawn, then I recommend the 12-volt or 18-volt battery powered cordless weed eaters.

The reason that stands behind my recommendation is that the 12 and 18-volt models are typically designed for residential use and are more versatile compared to the more powerful models. In fact, many manufacturers design these weed eaters as multi-use tools, manufacturing all sorts of useful attachments that will allow you to transform the weed eater into another lawn care tool such as a pruner, edger, blower, and more. It is useless to say that this is a cost-effective solution.

In addition to the voltage, you should also determine the type of the battery. If you are looking for a cost-effective solution, you will find out that the Ni-Ca batteries are less expensive compared to their Li-Ion counterparts.

However, the Ni-Ca batteries are heavier and have shorter lifespans, in addition to a shorter run-time and a longer charging time.

Another thing you should consider when choosing a cordless weed eater is the brand. This is an important aspect especially if you have, or plan to buy, other cordless lawn care tools, such as a lawn mower. In fact, many manufacturers make residential lawn care tools that have compatible batteries.

This is a great opportunity to increase your autonomy, especially because almost all tools are sold with a battery. In this way, you will be able to simply change the drained battery with a charged one and keep up with your work.

How To Maintain The Battery?

If the cordless weed eaters don’t need special maintenance procedures others than keeping the unit clean and changing the string when needed, there are a series of tips to follow if you want to maintain the battery in good conditions for a longer time.

The first advice is to buy a cordless weed eater only if you plan to use it regularly. The batteries tend to decrease their performances when not used for long periods of time, therefore, if you only want to trim the grass once in a while, you should consider investing in a corded or gas-powered model.

You should also keep the battery charged at all times. Keeping the battery completely drained when the tool is not in use also tends to damage it. For this reason, after you finish working, recharge the battery and then store it in a dry and cool place.

Also, when you charge the battery, make sure you charge it completely. It is an awful idea to only partially charge the battery, as this practice will reduce its performances and lifespan. Most chargers have LED indicators that let you know when it’s time to unplug it.

On the other hand, it is not advisable to wait until the battery is completely drained before recharging it. Ideally, the battery should still have about 15-20% power left when you place it in the charger. Also, pay attention to not leave the battery on the charger longer than it is necessary unless instructed differently by the operator’s manual.

Now, let’s have a look at the best battery powered cordless weed eater reviews to decide which is the right tool for you.
