Replacement Battery & Charger Kit for Worx 20V PowerShare Tools (2 Batteries & 1 Charger)

What It Is

This is a 2-pack of 20V Max Lithium batteries (2.0Ah each) plus a charger, designed to power and recharge any tool in the Worx PowerShare 20V platform—including lawn mowers, trimmers, blowers, and chainsaws.

Fitment & Compatibility

• Platform: Works with all Worx 20V PowerShare tools (e.g., WG779, WG801, WG929 mowers; WG163 trimmer; WG520 blower).
• Voltage: 20V Max (nominal 18V). Do not use on 40V or 56V Worx tools.
• Model numbers: Batteries are WA3570 (2.0Ah) or equivalent; charger is WA3880 or WA3744.
• Physical fit: Same slide-mount as all PowerShare batteries—no adapter needed.
• What to check: Verify your mower’s battery compartment can accept the 2.0Ah size (some mowers require higher Ah for runtime). Aftermarket batteries may have slightly different dimensions; measure your existing battery length/width if unsure.

Key Things to Know

• Runtime: 2.0Ah batteries give ~20-30 minutes of mowing on a small (14-16 inch) mower; expect less on larger decks or thick grass.
• Installation: Zero difficulty—slide on, click, and charge. The charger is a standard wall plug unit.
• Quality: OEM Worx, not aftermarket. Good cell protection and charge management, but 2.0Ah is the smallest capacity in the line.
• Gotcha: The charger charges one battery at a time (no dual slots). Expect ~1 hour charge time per battery.
• Warranty: 1-year Worx warranty included.

Should You Buy It

Buy this kit if you already own a Worx 20V PowerShare mower or tool and need spare batteries to extend runtime, or if you’re replacing worn-out originals. Skip it if your mower requires 4.0Ah or larger batteries (e.g., for a 20-inch deck) or if you need faster charging—look for the 4.0Ah twin pack with a dual-port charger instead.
