The Husqvarna B140 is a compact 40V lithium-ion battery designed for homeowners and professionals who use Husqvarna’s battery-powered outdoor equipment. With a 4.0Ah capacity, it offers a balance of runtime, weight, and portability, making it a popular choice for handheld tools such as string trimmers, hedge trimmers, chainsaws, and blowers.

Built around Husqvarna’s 40V battery platform, the B140 provides consistent power output throughout the discharge cycle, helping tools maintain performance until the battery is depleted. Its compact size makes it more comfortable for extended use compared to larger-capacity batteries.

The battery features integrated electronics that help manage charging, temperature, and power delivery. An onboard LED fuel gauge allows users to quickly check remaining charge levels before starting a job.
