WORX 20V PowerShare Pro 4.0Ah Battery (2-Pack) WA3674.2 – Long Runtime & Broad Tool Compatibility

Overview

The Worx 20 V Lithium-ion Battery 4.0 Ah PowerShare Pro 2-pack WA3674.2 is designed to power your Worx cordless tools with steady, reliable energy. The two-pack setup gives you ready-to-use backups when one battery is charging, reducing downtime during outdoor projects and busy DIY sessions. Expect a cooler operation thanks to advanced thermoplastic construction and a design that keeps cells from overheating during longer runs. An intelligent battery management system optimizes power delivery across each Li-ion cell, helping you get the most from your tools without guessing how much charge remains.

The battery features a built-in charge level indicator, so you can check remaining power at a glance and plan your workflow. When you need to swap out a battery, a push-button release makes tool detachment quick and simple, even when you are mid-task. The 360-degree cell protection reduces the impact of vibration and daily wear, contributing to longer service life while you work.
