Compatibility and practical use

This battery is designed to stay in the Worx Power Share ecosystem. It works with Worx Power Share 20V, 40V, and 80V cordless power tools, outdoor power equipment, and lifestyle products. If you own Worx Nitro tools, the 4.0Ah pack is especially well‑suited to sustain performance during extended cutting, trimming, mowing, or air‑blowing sessions.

Smart design and cooling

In addition to the intelligent management system, a thermoplastic material surrounding the cells helps dissipate heat more effectively. The result is a more stable power output under load and a reduced risk of overheating during longer runs. The 360° cell protection guards the internal cells against vibration and impact from heavy‑handed use or rough terrain.
