WA3732 3-5H Charger for 18V&20V Lithium Ion Battery Light on Battery, Replacement for Worx OEM

What It Is

This is a replacement 3–5 hour charger for 18V and 20V lithium-ion batteries that feature a charge indicator light. Designed for Worx power tools and lawn equipment (trimmers, blowers, chainsaws, etc.), it’s a direct OEM-style charger to keep your batteries topped up.

Fitment & Compatibility

• Battery voltage: Compatible with Worx 18V and 20V Max lithium-ion batteries that have a visible charge light on the battery pack itself.
• OEM replacement: Directly replaces the Worx WA3732 charger. Not for older NiCd or NiMH batteries, or batteries without the light.
• Charging time: 3–5 hours for standard 2.0Ah–4.0Ah packs. Larger packs (5.0Ah+) may take longer.
• Input: 120V AC, 60Hz (US standard). Do not use with 240V systems without a step-down transformer.
• Check your battery model: Works with WA3550, WA3551, WA3552, WA3571, WA3572, WA3573, WA3575, WA3576, and similar Worx 18V/20V batteries with the light. If your battery has no light, this charger won’t work.

Key Things to Know

• No installation needed: Plug into a standard wall outlet, insert battery, and the light indicates charging status.
• Quality note: Genuine Worx part, not a third-party knockoff. Should match OEM performance and safety standards.
• Common gotcha: The “light on battery” requirement is strict. If your battery doesn’t have a small LED indicator, this charger will not charge it.
• Charging speed: 3–5 hours is moderate—faster than some universal chargers but slower than rapid chargers. Fine for overnight or between jobs.

Should You Buy It

If you own Worx 18V/20V lithium batteries with a charge light and need a reliable, OEM replacement charger for your lawn tools or power tools, this is a safe, straightforward buy. Skip it if your batteries lack the indicator light or if you need a rapid charger.
