What It Is

This is a 6.0Ah high-capacity lithium battery replacement for Greenworks 40V tools. It’s designed to power cordless lawn mowers, string trimmers, hedge trimmers, leaf blowers, and other 40V MAX Greenworks equipment, offering longer run time than standard 2.0Ah or 4.0Ah packs.

Fitment & Compatibility

• OEM cross-reference: Replaces Greenworks battery models 29252, 20202, 22262, 25322, 20642, 27062, and 21242.
• Voltage: Must be 40V MAX (not 24V, 60V, or 80V). Check your tool’s label or manual for voltage.
• Physical fit: Same slide-in form factor as OEM Greenworks 40V batteries. Fits most Greenworks 40V tools with the standard push-button release.
• Charger: Works with Greenworks 40V chargers (model numbers typically end in “-00” or “-01”). Not compatible with 24V or 60V chargers.
• What to check: Look at your original battery’s model number (sticker on side). If it’s one of the listed OEM numbers, this will fit. If your battery has a different shape or voltage rating, it won’t work.

Key Things to Know

• Run time: 6.0Ah provides roughly 50% more run time than a standard 4.0Ah pack. Good for larger lawns (1/4 acre or more) or heavy trimming.
• Quality concerns: Aftermarket battery. Some users report inconsistent charge cycles or slightly shorter lifespan than OEM. Check warranty (usually 1 year vs. 2-3 years on genuine Greenworks).
• Installation: Trivial—slide battery onto tool’s battery mount until it clicks. No tools or wiring needed.
• Charging time: Expect 2–4 hours on a standard Greenworks 40V charger. Overheating may occur in direct sun; store battery cool before charging.

Should You Buy It

Buy this if you need a budget-friendly spare or extended run time for multiple Greenworks 40V tools and are comfortable with aftermarket performance. Skip it if you want OEM reliability, a longer warranty, or are using heavy-duty commercial equipment—stick with genuine Greenworks batteries for those.
