Reoben 6000mAh 40V Lithium Battery Replacement for GreenWorks 40V Battery Compatible with GreenWorks G-MAX 40V 29472 29462 2901319 24282 24252 21332 25322 20672(Green-1P)

What It Is

This is a 6000mAh 40V lithium-ion aftermarket battery designed to replace GreenWorks G-MAX 40V batteries. It powers any 40V GreenWorks cordless lawn mower, trimmer, blower, or other tool in the G-MAX platform.

Fitment & Compatibility

• Direct replacement for: GreenWorks models 29472, 29462, 2901319, 24282, 24252, 21332, 25322, 20672, and all G-MAX 40V tools.
• Check before buying: Verify your tool uses the GreenWorks G-MAX 40V battery platform (not the 60V or 80V systems). The battery slides into the same port and uses the same contacts as OEM GreenWorks batteries. No adapter needed.
• Measurements: Roughly 5.5 x 4.5 x 3.5 inches. Ensure your mower’s battery compartment has clearance—most G-MAX mowers accept this size.
• OEM vs aftermarket: This is a third-party battery. It will work with genuine GreenWorks chargers and tools, but may not have the same internal protection circuitry as OEM.

Key Things to Know

• Capacity vs runtime: 6000mAh is higher than the standard 2.0Ah or 4.0Ah OEM GreenWorks batteries. Expect longer runtime (up to 60–90 minutes on a mower, depending on load).
• Installation: Zero difficulty—slides in and clicks like OEM. No wiring, no tools.
• Charging: Compatible with any GreenWorks 40V charger (including the stock one). Full charge takes 2–4 hours.
• Quality concern: Some users report slightly shorter lifespan than OEM (1–2 seasons vs 2–3). Not water-resistant—keep dry. Warranty is typically 1 year from Reoben.

Should You Buy It

Buy this if you need a budget-friendly spare or replacement battery for an older GreenWorks 40V tool and don’t mind a slight trade-off in long-term durability. It’s a solid value for the capacity, but if you rely on your mower daily or want maximum reliability, stick with OEM.
