Replacement 20V Battery and Charger Starter Kit, WA3525 Lithium Battery and Charger WA3732 Compatible with Worx 20-Volt Cordless Power Tools

What It Is

This is a WA3525-compatible 20V lithium battery (2.0Ah) and WA3732 charger starter kit. It powers any Worx 20V cordless tool—including mowers, trimmers, blowers, and chainsaws—and serves as a spare or replacement for worn-out original packs.

Fitment & Compatibility

• Exact fit for: Worx WA3525 battery slot and WA3732 charger port. Compatible with all Worx 20V Max cordless tools (e.g., WG119, WG163, WG184, WG896 mowers; WG510, WG520 trimmers; WG545 blower).
• What to check: Ensure your Worx tool uses the slide-on 20V battery platform (not the older 18V or 40V line). Measure battery compartment depth—this battery is 4.5” long x 2.75” wide x 2.25” tall. Does not fit 40V tools or non-Worx brands without an adapter.
• OEM vs aftermarket: This is a genuine Worx OEM kit, so no compatibility guesswork. If you have a third-party tool with a Worx-style port, test fit before buying.

Key Things to Know

• Installation: Zero difficulty—slide battery onto tool until it clicks. Charger plugs into standard 120V outlet. Green LED means fully charged.
• Battery life: 2.0Ah provides ~30-40 minutes of mowing on a small (14-16”) cordless mower, or ~60 minutes for a trimmer. Not for heavy-duty all-day use.
• Charger speed: WA3732 charges the 2.0Ah battery in ~60 minutes. No fast-charge feature—plan ahead for back-to-back jobs.
• Common gotcha: This kit includes only one battery. If you need continuous runtime for larger lawns, buy a second battery separately. Also, the charger is not compatible with Worx 40V batteries.

Should You Buy It

Yes, if you need a reliable spare battery for light to medium yard work with Worx 20V tools and want OEM reliability at a fair price. It’s ideal for small lawns (under 1/4 acre) or occasional trimming. Skip it if you need high-capacity runtime (get the 4.0Ah) or already own multiple WA3525 batteries—buy just the charger instead.
