2Pack 40V 6000mAh Batteries and Charger Replacement for Greenworks 40V Battery and Charger, Compatible with Greenworks 40Volt GMAX Lithium 29462 29472 29252 22262 25322 Cordless Tools

What It Is

This is a 2-pack of 40V 6000mAh replacement batteries plus a charger, designed for Greenworks 40V GMAX cordless lawn mowers, trimmers, blowers, and other tools. It provides higher capacity than standard 2.0Ah or 4.0Ah packs, extending runtime for larger yards or heavy-use tasks.

Fitment & Compatibility

• Brand & Voltage: Works only with Greenworks 40V GMAX tools. Not compatible with 60V, 80V, or older 24V/36V systems.
• Specific Models: Compatible with models including 29462, 29472, 29252, 22262, 25322, and many other 40V GMAX tools. Check your tool’s model number on the battery compartment or manual.
• Physical Fit: The battery shape matches Greenworks GMAX packs. Measure your existing battery: these are ~5.5 x 3 x 4 inches. Ensure your tool’s battery bay has clearance for the slightly taller 6.0Ah case.
• OEM vs Aftermarket: This is an aftermarket replacement, not Greenworks OEM. It may have slight differences in plastic molding or latch feel but is designed to snap in securely.

Key Things to Know

• Installation: No tools needed. Slide battery into tool until it clicks. Charger plugs into standard wall outlet; battery charges in 2-4 hours.
• Quality & Safety: Aftermarket batteries can vary. This set has a 4.4 rating but check recent reviews for swelling or charging issues. Use only the included charger to avoid damage.
• Runtime vs Weight: 6000mAh gives 50-100% more runtime than a 2.0Ah or 4.0Ah pack, but adds weight. Heavier mowers may feel more front-heavy.
• Warranty: Aftermarket batteries typically come with a 1-year warranty, not Greenworks’ longer OEM coverage. Save your receipt.

Should You Buy It

Buy this if you own multiple Greenworks 40V GMAX tools and need longer runtimes for large lawns or heavy trimming, and you’re comfortable with aftermarket quality. Skip it if you prefer OEM reliability, need a warranty longer than 1 year, or have only light-duty tasks where a 2.0Ah pack suffices.
