2 Pack 32V 3.5Ah Battery Replacement for Worx WA3537 Compatible with Worx 32 Volt Cordless Tools WG175.1 WG275 WG575.1 WG924.4, More Runtime

What It Is

This is a 2-pack of 32V 3.5Ah lithium-ion replacement batteries designed for Worx 32-volt cordless tools. It’s intended for extended runtime on string trimmers, blowers, chainsaws, and lawn mowers like the WG175.1, WG275, WG575.1, and WG924.4.

Fitment & Compatibility

Before buying, confirm your tool’s voltage is 32V (not 20V or 40V). These batteries replace the OEM Worx WA3537 and fit models such as the WG175.1, WG275, WG575.1, WG924.4, and other 32V Worx tools using the same slide-on interface. Check your tool’s manual or battery compartment for a matching WA3537 part number. Measure the battery slot: the WA3537 dimensions are roughly 5.1 x 3.1 x 2.6 inches. These are aftermarket replacements, not genuine Worx, so verify that your charger supports 32V lithium-ion (most Worx 32V chargers do). Do not use with 20V or 40V tools.

Key Things to Know

• Quality & Capacity: These are 3.5Ah each, offering roughly 20–30% more runtime than standard 2.5Ah Worx batteries. They are aftermarket, so cell quality may vary from OEM—expect slightly shorter lifespan but comparable initial performance.
• Installation: No tools required. Slide the battery onto the tool’s mount until it clicks. Ensure the contacts align and the release latch works smoothly.
• Common Gotchas: Aftermarket batteries may not charge on all Worx chargers—test compatibility with your specific charger model. Also, some users report the battery indicator lights may not function identically to OEM. Store in a cool, dry place to maximize lifespan.
• Warranty: Typically 12–24 months from the seller, but not covered by Worx. Check the return policy before purchase.

Should You Buy It

Buy this if you own multiple 32V Worx tools and need extra runtime for larger yards or prolonged use, and you’re comfortable with aftermarket parts. Skip it if you prefer OEM reliability or have a 20V/40V system—this is strictly for 32V tools.
