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

What It Is

The WORX WA3537 is a 32V, 3.5Ah lithium-ion battery replacement for the WA3536 and WA3550. It powers all Worx 32V cordless tools, including string trimmers (WG175.1, WG275), hedge trimmers (WG575.1), and blowers (WG924.4). It’s a direct drop-in for your existing Worx 32V system.

Fitment & Compatibility

• Check model number: This battery fits only Worx 32V tools. Compatible models include WG175.1, WG275, WG575.1, WG924.4, and others in the 32V line. It will not work with Worx 20V or 40V tools.
• Physical dimensions: 5.5 x 4.5 x 3.5 inches; weight ~1.5 lbs. Measure your battery compartment to ensure clearance (most 32V Worx tools share the same slot).
• OEM vs aftermarket: This is an OEM Worx battery, not a third-party knockoff. It uses the same connector and charging profile as the original WA3536/WA3550.
• Charger compatibility: Works with the standard Worx 32V charger (WA3730 or WA3740). Do not use with 20V or 40V chargers.
• Voltage check: 32V nominal, 3.5Ah capacity. If your tool requires a higher amp-hour battery (e.g., 4.0Ah), this will still run but provide less runtime.

Key Things to Know

• Installation: Zero difficulty—slide into the tool’s battery slot until it clicks. No wiring or tools needed.
• Runtime: 3.5Ah delivers roughly 30-45 minutes of moderate trimming or 20-30 minutes of heavy blowing. Less than the 4.0Ah option but lighter.
• Charging time: About 1.5 hours with the standard charger. Avoid overcharging; unplug once full.
• Common gotcha: Some users report the battery won’t charge if stored in extreme cold or heat. Keep it between 40-80°F before charging.

Should You Buy It

Yes, if you already own a Worx 32V tool and need a reliable replacement or spare. It’s a genuine OEM battery at a fair price, with solid runtime for light to medium yard work. Skip it if you need longer runtime (go for the 4.0Ah) or if your tool is 20V/40V.
