Husqvarna B140 4 Ah 40V Lithium Battery, Replaces Bli22, Gifts for Men, 970457202
Product Description:
The Husqvarna B140 is a high-capacity 40V lithium-ion replacement battery designed for the complete range of Husqvarna MAX battery-powered outdoor tools — delivering 4 amp hours (144 Wh) of consistent, fade-free power for extended runtime during yard work, landscaping, and property maintenance. Whether you're running a leaf blower, string trimmer, chainsaw, hedge trimmer, pole saw, or edger, the B140 drops into any Husqvarna MAX battery tool and provides the runtime and power output to get through demanding jobs without slowing down. It directly replaces the older BLi22 battery with improved capacity and performance.
The B140's high-power lithium-ion cells are engineered to deliver continuous, stable power output across a wide range of climate conditions — from hot summer yard work to cold-weather property cleanup. Unlike budget batteries that lose output rapidly under load or in extreme temperatures, the B140 maintains consistent performance throughout its discharge cycle, ensuring your chainsaw cuts with the same authority at 20% charge as it does at full.
The active cooling system is a critical durability feature. During demanding applications like chainsaw use and during fast charging, the battery manages heat through built-in cooling infrastructure that maintains optimal operating temperature, preventing thermal degradation that shortens battery lifespan. This active thermal management extends both the per-session performance (no heat-related power throttling) and the overall lifetime of the battery.
An intuitive LED charge indicator on the battery body displays the current charge level at a glance — press the button, read the lights, and know immediately whether you have enough charge for the next task or need to swap to a second battery. Intelligent discharge management protects the battery from deep discharge, which is the single most damaging event for lithium-ion cells. The B140's electronics monitor cell voltage continuously and shut down the battery before it reaches the damage threshold, ensuring consistent capacity across hundreds of charge cycles.
The B140 is rechargeable up to 600 times, delivering years of reliable service for homeowners and part-time users. You can recharge at any time, even when the battery is partially drained — there's no memory effect, so topping off between tasks doesn't reduce total capacity over time. The battery is compatible with Husqvarna's QC250 quick charger and the 40-C80 standard charger (both sold separately).
As part of Husqvarna's BLi-X interchangeable battery system, the B140 fits every Husqvarna MAX battery tool in the lineup — one battery platform across your entire fleet of outdoor power equipment. Swap the same battery from your blower to your trimmer to your chainsaw and back without buying tool-specific batteries. At just 3.02 pounds, the B140 adds minimal weight to handheld tools.
