What It Is

This is a 40V, 6.0Ah aftermarket lithium-ion battery designed as a replacement for GreenWorks G-MAX 40V power tools and lawn mowers. It powers cordless mowers, trimmers, blowers, and chainsaws that use the G-MAX battery platform.

Fitment & Compatibility

Before buying, confirm your tool uses the GreenWorks G-MAX 40V system—not the newer 40V “Twin Force” or 60V/80V platforms. This battery fits models like 29252, 20202, 22262, 25312, 25322, 20642, 22272, 27062, and 21242. It also works with any GreenWorks G-MAX tool that originally accepted a 2.0Ah, 4.0Ah, or 5.0Ah battery. Physically check the battery slot shape: it’s the standard G-MAX slide-on design with a top-mounted release button. This is not compatible with 24V, 80V, or non-G-MAX 40V tools.

Key Things to Know

• Quality variance: Aftermarket batteries often use lower-grade cells than OEM GreenWorks units. Expect slightly shorter runtime and faster capacity loss over 1-2 years.
• Installation: No tools required—slide the battery onto the tool until it clicks. Ensure the release latch engages fully before use.
• Charging: Use only a GreenWorks G-MAX 40V charger (models like 29272 or 29482). Third-party chargers may damage the battery or cause slower charging.
• Common gotcha: This battery may not fit tightly in older G-MAX tools due to minor mold differences. If it wobbles, add a thin foam strip inside the slot for a snug fit.

Should You Buy It

Buy this if you need a budget-friendly spare or replacement for an aging GreenWorks G-MAX 40V battery and don’t mind slightly shorter lifespan than OEM. Skip it if you want maximum runtime or reliability for heavy daily use—stick with a genuine GreenWorks battery.
