Best cordless grass trimmers with a battery and charger

The RYOBI 40V HP Brushless 17” String Trimmer Kit is our strongest all-round fit for demanding growth. Choose the RYOBI 18V ONE+ 13” kit for lighter edging, or DEWALT’s 60V kit for a wider cutting swath.

Quick answer

For a demanding lawn, the RYOBI 40V HP Brushless 17” String Trimmer Kit pairs a 17-inch swath with a 6Ah battery and rapid charger. The RYOBI 18V ONE+ 13” kit is a lighter-duty option with edging conversion, while DEWALT’s 60V kit includes two batteries and suits heavier growth. RYOBI’s 40V attachment-capable kits are worth considering if you want a shared power head across compatible yard attachments.

Common questions

Questions before you buy

Which is better, a gas or battery weed eater?

A battery trimmer is usually easier to start and maintain, and avoids fuel handling and exhaust at the point of use. Gas can suit long sessions away from charging access or sustained heavy clearing; match a battery model’s voltage, capacity and cutting width to the job.

Does a cordless grass trimmer kit always include a battery and charger?

No. Manufacturers often sell the same tool as a bare tool and as a kit. Check the included-items list for both; every pick above lists a battery and charger.

What size line does a RYOBI battery weed eater use?

It depends on the model. The RYOBI 18V ONE+ 13-inch kit uses .080-inch line, while its 40V HP 17-inch kit specifies .105-inch line. Check the manual for your exact model before reloading.

How wide should a cordless string trimmer cut?

A wider swath covers more ground per pass and suits open areas, while a narrower head is easier to guide around beds and tight spaces. Choose according to the balance of coverage and precision your yard needs.

Can one battery power different RYOBI trimmers?

RYOBI states that batteries are interchangeable within the same voltage platform, such as 18V ONE+. An 18V battery will not fit a 40V tool, so check the platform label when choosing a spare or bare tool.
