ARyee 40V 3.0Ah WA3580 Replacement for Worx 40V Battery Compatible with Worx 40 Volt Tools WG180 WG280 WG380 WG580 (Not Fit for 2x20V Tools)

What It Is

The ARyee 40V 3.0Ah WA3580 is an aftermarket replacement battery for Worx 40V cordless tools, including lawn mowers, trimmers, blowers, and chainsaws. It powers tools like the WG180, WG280, WG380, and WG580, but is not compatible with Worx 2x20V dual-battery tools.

Fitment & Compatibility

• Models it fits: WG180, WG280, WG380, WG580, and other Worx 40V tools using the WA3580 battery platform. Check your tool’s model number—if it lists “40V Max” and uses a slide-on battery pack, this will likely work.
• Does not fit: 2x20V tools (those requiring two 20V batteries, e.g., WG744, WG745, WG746). Verify your tool’s voltage and battery port shape before buying.
• OEM vs. aftermarket: This is a third-party battery, not from Worx. It should physically fit the same slot, but performance and longevity may differ from OEM.
• Measurements: No specific dimensions listed, but it’s designed to match the WA3580 form factor. Ensure your battery compartment is clear of debris and the connector pins are clean.

Key Things to Know

• Quality & safety: At 3.9 stars from only 9 reviews, this is a budget option. Check for UL or CE certification marks on the battery—aftermarket batteries sometimes lack robust protection circuits, increasing fire risk.
• Installation: No tools required. Slide the battery into the tool’s slot until it clicks. If it doesn’t seat firmly, don’t force it—check for obstructions or compatibility.
• Performance: 3.0Ah capacity is typical for standard 40V tools; runtime will be similar to Worx’s 2.0Ah or 4.0Ah packs, but actual runtime depends on your tool and load. Expect less power under heavy use (e.g., thick grass) compared to OEM.
• Warranty & returns: Verify the seller’s return policy. Some aftermarket batteries have shorter warranty periods or no support.

Should You Buy It

Buy the ARyee WA3580 if you need a low-cost spare battery for occasional use on a Worx 40V mower or trimmer and are comfortable with the risks of third-party electronics. For daily heavy use or critical tasks (e.g., mowing large lawns), invest in a genuine Worx battery for better reliability, safety, and warranty support.
