DONGPUCUN 32V 3.5Ah Lithium Battery for Worx 32V Battery WA3537 Compatible with 32V Tools WG175.1 WG275 WG575.1 WG924.4 Replacement for Worx 32V Battery

What It Is

This is a 32V 3.5Ah lithium-ion replacement battery designed for Worx 32V cordless lawn mowers, trimmers, and other tools. It’s a direct substitute for the OEM Worx WA3537 battery, powering models like the WG175.1, WG275, WG575.1, and WG924.4.

Fitment & Compatibility

• Voltage & Chemistry: Must be 32V lithium-ion—confirm your Worx tool is 32V (not 20V or 40V). This battery is not compatible with 18V or 24V systems.
• Model Check: Works with Worx WA3537, WA3550, WA3551 battery packs. Fits mowers WG175.1, WG275, WG575.1, WG924.4, plus trimmers/edgers using the same battery bay.
• Physical Fit: Measures approx. 5.5 x 3.5 x 3.5 inches; slides into the same slot as OEM. Verify battery compartment depth—some older models may have tight clearance.
• OEM vs Aftermarket: This is a third-party replacement. It uses the same connector and voltage, but charge/discharge circuitry may differ slightly. Not recommended for tools still under warranty.

Key Things to Know

• Capacity vs Runtime: 3.5Ah is the same as the OEM WA3537. Expect roughly 30–45 minutes of mowing on a standard lawn, depending on grass thickness and speed setting.
• Installation: Drop-in replacement—no tools or modifications needed. Charge with any Worx 32V charger (or compatible third-party 32V charger). Do not use 20V chargers.
• Quality Notes: Some users report slightly shorter lifespan than OEM (200–300 cycles vs 300–400). The plastic housing may feel less robust. Avoid leaving it on the charger for days to prevent swelling.
• Common Gotcha: The battery indicator (if present) may not be accurate. Test runtime on a small area first to gauge real capacity.

Should You Buy It

If you need a budget-friendly spare for an older Worx 32V mower or trimmer, this is a solid value—just expect slightly less longevity than the OEM pack. Avoid if you rely on maximum runtime or want warranty coverage; stick with genuine Worx for that.
