2Pack Replacement for Worx 20V Battery and Charger Kit - Extra Runtime

Our review of the 2Pack Replacement for Worx 20V Battery and Charger Kit finds it best suited for homeowners and casual landscapers who need a straightforward, cost-effective way to extend runtime for Worx 20V tools. The kit includes two 20V 3.0Ah batteries and a WA3732 charger, and the single biggest reason to buy is the additional run time provided by the 3000mAh cells that let users work longer between charges without modifying tools or chargers.

Key Features

• Package Included: The kit ships with two 20V 3.0Ah batteries and one WA3732 charger so you get immediate extra runtime for multiple tools out of the box.
• Wide Compatibility: Designed as replacement batteries for Worx WA3520, WA3525, WA3575 and WG151s/WG155s/WG251s/WG255s models, offering plug-and-play fit without adapters.
• Easy Installation: The batteries install securely and cleanly into the original tool battery bay, so no tools or modifications are required to use them.
• Extended Runtime: Each cell uses a 3000mAh high-density lithium pack to deliver longer runtime and a longer cycle life than many lower-capacity options.
• Charger Specs: The included WA3732 charger accepts 100-240V input and outputs 20V, making it usable on common household power worldwide.
• Safety Tested: Built-in protection prevents overcharge, overheating and short circuits, and the cells have been tested for durability, including a 1.5m drop test.

Who It's For

This kit is ideal for homeowners, light-duty landscapers and DIYers who already own Worx 20V tools and want a simple way to reduce downtime by swapping to a fully charged spare pack. It suits people who value compatibility and an easy, worry-free installation over proprietary fast-charge features.

It is less suitable for professional contractors who need very long continuous runtimes or rapid multi-battery charging solutions; likewise, anyone who requires official manufacturer warranty coverage for original-brand batteries may prefer OEM packs.
