What It Is

The Husqvarna B140 is a 40V, 4 Ah lithium-ion battery designed to power Husqvarna’s 40V cordless lawn mowers, trimmers, blowers, and other outdoor equipment. It replaces the older BLi22 model and is a drop-in upgrade for compatible tools.

Fitment & Compatibility

  • Direct replacement for BLi22 (model 970 45 72-02) – fits all Husqvarna 40V tools originally using BLi22.
  • Check your tool’s voltage and connector: Must be 40V Husqvarna (not 36V or 56V). Connector is the same slide-in style used on all current 40V Husqvarna batteries.
  • Not compatible with other brands (e.g., Poulan Pro, Craftsman, or other OEMs) unless explicitly stated.
  • Physical size: 5.5 x 3.5 x 4.5 inches, weight ~1.5 lbs – fits all 40V Husqvarna battery compartments.
  • Before buying: Confirm your tool’s model number and that it accepts a 40V slide-in battery. Verify charger compatibility (Husqvarna QC40 or QC80 chargers work).

Key Things to Know

  • Quality: OEM Husqvarna, not aftermarket – provides consistent power and longer lifespan than generic alternatives.
  • Installation: Zero difficulty – slides into any 40V Husqvarna tool or charger. No tools or adapters needed.
  • Run time: 4 Ah gives ~40–60 minutes on a mower (depending on load/grass height) – adequate for medium yards (~0.25–0.5 acre).
  • Common gotcha: This battery is not compatible with Husqvarna’s older 36V system (e.g., BLi10, BLi20). Check your tool’s voltage label before buying.
  • Charging: Use only Husqvarna 40V chargers (QC40 or QC80). Third-party chargers may damage the battery or void warranty.

Should You Buy It

Buy this if you own a Husqvarna 40V cordless tool and need a direct OEM replacement for a worn BLi22, or want a spare battery for longer jobs. It’s a reliable, drop-in upgrade with no guesswork, ideal for homeowners with medium-sized lawns. Skip if your tool is 36V or if you need a higher capacity (e.g., 6 Ah) for heavy use.
