2Pack 3000mAh Battery Replacement for Worx PowerShare 20V Batteries WA3520 WA3525 WA3575 WA3669 WG151s WG155s WG251s WG255s WG540s WG545s WG890 WG891

What It Is

This is a 2-pack of 3000mAh lithium-ion batteries designed to replace Worx PowerShare 20V batteries. It powers any Worx tool or mower that uses the PowerShare platform—including string trimmers, blowers, and mowers like the WG890 and WG891.

Fitment & Compatibility

Before buying, confirm your tool uses the Worx PowerShare 20V system (not the older 20V Max or 40V line). This pack directly replaces OEM models: WA3520, WA3525, WA3575, WA3669, WG151s, WG155s, WG251s, WG255s, WG540s, WG545s, WG890, WG891.

• Physical check: Measure your existing battery compartment. These are standard PowerShare size (approx. 4.7 x 3.1 x 2.6 inches).
• Voltage match: Must be 20V nominal.
• Watt-hour rating: 54Wh (under FAA limits for air travel).
• No adapter needed—slides directly into any PowerShare-compatible tool or charger.

If your Worx tool says “PowerShare 20V” on the battery housing, it’s compatible. Avoid if your tool uses a different battery platform (e.g., older 18V or 40V).

Key Things to Know

• Quality: Aftermarket, not OEM Worx. Expect slightly lower runtime than genuine Worx 2.0Ah packs, but adequate for light to medium use.
• Installation: Zero difficulty—just slide in and click. No tools required.
• Charging: Works with any Worx PowerShare 20V charger. Do not use with non-Worx chargers.
• Gotcha: These are 3000mAh (3.0Ah) vs. standard 2.0Ah OEM packs. They provide ~50% more runtime but may be slightly heavier. Not suitable for heavy-duty continuous mowing on large lawns.

Should You Buy It

Buy this if you need a budget-friendly spare set for occasional trimming, blowing, or small-to-medium mowing jobs. Skip it if you demand OEM reliability, need maximum runtime for all-day mowing, or require a warranty from Worx.
