Product overview
The Husqvarna 40-B140X is a lightweight 36 V, 4 Ah BLi‑X battery optimised for hedge trimmers and small top-handle chainsaws. It combines ActiveCool temperature management, IPX4 weather resistance and built-in Bluetooth connectivity so it performs reliably on professional sites and can be monitored via Husqvarna Fleet Services.
ActiveCool temperature management
ActiveCool actively cools the battery during both charging and operation. That keeps performance steady in demanding use and helps prolong usable lifetime compared with passive cooling alone.
Integrated connectivity
A built-in Bluetooth module allows the battery to connect to Husqvarna Fleet Services. You can access last known location, charging cycles and basic health information when the battery is linked to the fleet system.
All‑weather reliability (IPX4)
The battery meets IPX4 water‑resistance requirements, so it tolerates splashing and typical wet conditions encountered on site. It is designed for year‑round professional use, though charging and long‑term storage should follow the manual.
