Best Cordless String Trimmers Buyer Guide

There are factors that you should take into consideration before buying a cordless string trimmer.

Below are the most important factors to ensure that you get the best cordless string trimmer that fits your specific needs.

Runtime/ Charge Time

Since cordless trimmers ideally come with a single battery, it is essential you know its runtime.

Go for a trimmer with a longer-lasting runtime to avoid the inconveniences of having to recharge the battery after a few minutes of use.

The higher the AH of a battery, the longer the run time after a single charge.

Some of the best string trimmers have a run time of up to 60 minutes.

Charging time, on the other hand, is also another factor to consider.

A battery should not take too long to charge since it minimizes the trimmer’s downtime.


For a string trimmer to be useful, it should be capable of cutting overgrown and tough weeds.

The more the workloads, the more powerful trimmer you need.

Nickel-cadmium batteries have less power and require frequent charges, while lithium batteries will give you longer runtime and better performance.

You can determine how powerful a battery is by checking its voltage; the more the voltage, the more powerful it is.

However, the battery recharging and replacements may be too frequent, leading to more maintenance costs.

A good string trimmer should be light and strong at the same time due to the kind of task it performs.

Battery type largely determines the trimmer’s weight; lithium-ion batteries are lighter than Nickel-Cadmium batteries.
