Factors to Consider When Buying Battery-Powered Weed Eaters

The following is a list of factors to consider when buying the best battery-powered weed eater:

Battery voltage:

The first factor to consider before buying a lightweight battery operated weed eater is the battery voltage itself. The battery voltage largely determines the strength of the weed wacker/eater and the length of run time itself. For instance, the models compatible with 56V batteries are much stronger than the 20V counterparts.

Not only are they stronger and more capable of handling thick weeds, the battery run time is longer, allowing you to cover more ground with one battery.

PerformanceAdjustability, convertibility:

The next factor to consider is the adjustability and convertibility of the trimmer’s features. If you are on the shorter side, buying a height-adjustable model is likely your best bet.

Additionally, trimmers that are able to be converted from trimmer to edger via a button are the best models for those looking for multi-functional trimming.

Trimming diameter:

A third factor to consider before buying a battery-powered weed eater is the trimming diameter. The trimming diameter will directly affect the amount of yard you can tackle on one battery charge.

While a 10″ trimming diameter is plenty viable, a 15″ diameter obviously tackles more lawn at once, and considerably more at that.

SignBattery included/not included:

The final factor to consider is whether or not the models you are considering come with the battery included. For instance, the strongest weed eater on the list, the EGO Power+ ST1500-S, is the best trimmer available but it is already very pricey without the battery included.

If you truly need a super-high powered trimmer then perhaps you do buy this model and a battery separately. But for most, the less strong models with batteries included should be plenty to get you by.

Battery-Operated Weed Eaters FAQ

Who makes the best battery powered weed eater?

The best battery powered weed eater is likely the option from EGO. The EGO Power+ ST1500-S is the highest-powered weed eater in the reviews list, meaning that it is assumedly the best option.

However, not coming with a battery does hurt the value of this model. The best battery included model is likely the BLACK+DECKER LSTE523 Li-On String Trimmer with its two-speed control.

What is RPM regarding weed eaters?

The RPM of a weed eater means revolutions per minute. The higher the revolutions per minute, the higher the strength of the weed wacker because more revolutions per minute obviously mean faster string spinning, and thus more powerful trimming.

The models with the higher RPMs will always trim at a more effective rate than those with lower RPMs.

Do I need a convertible weed eater model?

The convertible weed eater models are perfect for those with muscular issues or weaknesses. The convertibility via the button on some models is more ideal for those who may struggle to hold a weed wacker at an alternate angle for edging versus trimming.

For older folks, convertible models are greatly beneficial to the joints and muscles. Also, some of the convertible models have wheels when in edging mode, which is helpful for getting perfectly straight edge lines.

What is automatic line feed?

An automatic feed line simply means that you do not have to bump the weed wacker to receive more trimming string. On standard weed whackers, you draw more string when it runs out by bumping the head of the wacker on the ground, which releases string by loosening the string holding mechanism.

Automatic line feed saves you from having to utilize this method and makes an operation that much more simple.

You need to remember not only to care about your garden but also about the safety of the house itself. With smoke detectors, you protect your home from fires. You may also be interested in better safety lighting.

Conclusion

So in concluding, what is the best battery powered weed trimmer? Well, that depends on your situation, your yard, and your own capabilities.

However, the BLACK+DECKER LCC221 20V MAX Lithium String Trimmer/Edger Plus Sweeper Combo Kit is likely the best value package on the market. But there are ten highly qualified options on the list that are all great for different reasons and in varying circumstances.

If you are looking for an absolute beast of a trimmer, look to the higher voltage battery options. If you simply need something to take care of small patches or areas of lawn, the lower voltage models will serve you just fine. So get prepared today and find the perfect model for your yard!
