6.0Ah 1Pack 29462 29472 Lithium 40V Battery Replacement Compatible with Greenworks 40V 24282 20312 24252 21332 25322 20672 G-Max Cordless Power Tools

What It Is

This is a 6.0Ah lithium-ion 40V replacement battery pack for Greenworks G-Max cordless tools. It powers lawn mowers, string trimmers, blowers, and chainsaws that use the 40V platform—giving you longer run time than the standard 2.0Ah or 4.0Ah packs.

Fitment & Compatibility

• Model numbers: Compatible with Greenworks 24282, 20312, 24252, 21332, 25322, 20672, and all G-Max 40V tools using the original 29462 or 29472 battery.
• Physical check: Measure your existing battery compartment (approx. 5.5" x 3.5" x 2.5") to ensure clearance. This pack uses the same slide-in mount as OEM.
• OEM vs aftermarket: This is a third-party replacement, not Greenworks branded. It works with genuine Greenworks chargers (40V models), but charge times may vary.
• What won’t work: Not compatible with Greenworks 60V, 80V, or 24V systems, or any non-G-Max 40V tools from other brands.

Key Things to Know

• Capacity vs weight: 6.0Ah provides up to 50% longer run time than a 4.0Ah pack, but weighs about 2.5 lbs—slightly heavier than OEM equivalents.
• Installation: Slides in and clicks—no tools needed. Ensure terminals are clean and dry before each use.
• Charge time: Expect 2–4 hours on a standard Greenworks 40V charger. Does not include a charger.
• Common gotcha: Some users report the battery indicator lights (if equipped) may not match OEM behavior. Verify your tool’s low-battery warning still triggers correctly.

Should You Buy It

Buy this if you have multiple Greenworks 40V G-Max tools and need a budget-friendly spare or upgrade for longer run time. It’s a solid value at $39.99, but skip it if you require OEM warranty support or need to match a specific tool’s tight battery compartment—stick with a genuine Greenworks 29462 for guaranteed fit.
