Thus, gardeners and homeowners prefer the corded and cordless units over the gas-powered trimmers since they don’t hurt your ears and hands that much. Further, cordless trimmers are more comfortable to use.

Weight and Controllability

Since you will be using your hands and arms mostly when using a string trimmer, it is wise to get a lightweight tool that you can easily carry around the yard.

It is also ideal if your trimmer is compatible with various attachments to make your garden tool more versatile. You can attach an edger, blower, or mower with a string trimmer.

Additional Features

How do you determine if you have a bad trimmer clutch?

You will know that you have a malfunctioning clutch if the trimmer head is not spinning, does not stop spinning, or turns erratically. There are several reasons why a trimmer clutch fails as follows:

  • The high temperatures due to friction
  • A metal fatigue after years of use.
  • The boots of the housing are broken or already smooth due to repeated use.

Is it okay to overcharge a Lithium-Ion battery?

Unlike lead-acid batteries, Li-ion cells do not need to be fully charged. It is even better not to fully charge them because high voltages put stress on the battery cells.

On the other hand, using a lower voltage threshold helps prolong the battery life but can reduce its runtime. It is best not to overcharge Lithium-ion cells since it can cause plating and may pose safety risks.
