Our take on the Black & Decker 40V MAX Lithium String Trimmer

The Black & Decker 40V MAX Lithium String Trimmer is a cordless straight-shaft trimmer with a 13-inch cutting swath and a 40V MAX lithium-ion battery. It weighs about 6.4 lb, so it is light enough to carry around a yard for a full session. It suits homeowners with small to mid-size lawns who want to skip extension cords and gas cans. Against 18V and 20V trimmers it cuts wider and holds power longer, but it is heavier and less capable than 60V or gas models in thick brush.

What reviewers say

Owners generally find it an easy, lightweight trimmer for routine yard work and like that the battery is shared with other 40V tools. Complaints center on runtime in thick grass and on the bump-feed head, which some find fussy.

What people mention
  • WeightPraisedOwners say it is light enough to carry for a full trimming session.
  • BatteryMixedThe shared 40V battery is convenient, but runtime falls off in thick grass.
  • Cutting powerMixedIt handles lawn edges fine but struggles in heavy brush compared with gas models.

Questions and answers

Is this trimmer good for a small yard?
Yes. The 13-inch swath and light body suit routine edging and trimming on small to mid-size lawns. It is not built for overgrown brush.
Does the battery fit other Black & Decker tools?
It uses the Black & Decker 40V MAX battery system, so it shares packs with other 40V MAX tools in that line. Check the tool's label for 40V MAX compatibility.
How long does the battery last?
Runtime depends on grass thickness and conditions. Owners report it covers a typical suburban yard on one charge but drains faster in tall or wet grass.
What line size does it take?
It uses standard replacement spools for this model. Match the spool to the trimmer's model number rather than buying a generic spool.
How does it compare with a gas trimmer?
It is lighter, quieter and starts instantly, but a gas trimmer has more power for thick brush and long sessions. For lawn edges, the cordless trimmer is easier to live with.
Can it edge along a sidewalk?
It can trim along edges, but the fixed straight head is less precise than a dedicated edger. Many owners rotate the head to edge and accept the compromise.
