What It Is

This is an aftermarket 6.0Ah 40V lithium-ion battery replacement for Greenworks 40V G-MAX cordless lawn mowers, string trimmers, blowers, and other outdoor power tools. It powers tool models that use the G-MAX battery platform.

Fitment & Compatibility

• Check your tool’s voltage and battery platform: This battery is 40V and uses the G-MAX slide-on interface. It will not work with Greenworks 24V, 60V, or 80V tools, or with the older 40V “twin-port” (non-G-MAX) batteries.
• Compatible OEM part numbers: 29472, 29462, 2901319, 24282, 24252, 21332, 25322, 20672, 2101602, 20312.
• Common tool models that fit: Greenworks 40V G-MAX mowers (e.g., 25322, 21332), trimmers (e.g., 2101602), and blowers (e.g., 24282). If your tool accepts the slide-on battery with the G-MAX logo, it fits.
• Physical check: Measure your old battery compartment – this battery is roughly 5.75" x 3.5" x 4.5". If your tool is designed for a G-MAX battery, it will slide right in.

Key Things to Know

• Not OEM, but functional: This is a third-party replacement, not a genuine Greenworks battery. It uses compatible cells but may have slightly shorter runtime or faster self-discharge than the original.
• No charger included: You need a Greenworks 40V G-MAX charger (sold separately) to charge this battery.
• Installation is tool-free: Slide the battery onto the tool’s battery mount until it clicks. Press the release button to remove.
• Watch for counterfeit listings: Price is below OEM ($60-80), but verify seller ratings and return policy. Some users report battery gauge inaccuracies or early failure.

Should You Buy It

Buy this if you need a budget-friendly spare or replacement for a Greenworks 40V G-MAX tool and don’t mind sacrificing a bit of runtime and warranty for the lower price. It’s a solid value for light-to-medium use, but if you rely on the tool daily or need maximum longevity, stick with the genuine Greenworks 29472.
