40V 6.5Ah 29462 29472 Replacement for Greenworks 40 Volt Battery and Charger 29482 Compatible with Greenworks 40V Lithium-Ion Battery 29252 20202 22262 40 Volt G-MAX

What It Is

This is a 40V 6.5Ah lithium-ion battery (model 29462/29472) designed as a direct replacement for Greenworks 40V G-MAX cordless lawn mowers, string trimmers, blowers, and other outdoor power tools. It provides higher runtime than standard 2Ah or 4Ah packs, suitable for medium to large yards.

Fitment & Compatibility

Before buying, verify your tool uses the Greenworks 40V G-MAX battery platform (not the newer 60V or 80V systems). This battery is compatible with models 29252, 20202, 22262, 29482, and all Greenworks 40V tools that accept the G-MAX slide-on battery pack. It will not fit older Greenworks 24V or 80V tools. Check that your mower’s battery compartment is large enough for the 6.5Ah pack (slightly taller than 4Ah versions). If you have a Greenworks 40V charger, it will charge this battery.

Key Things to Know

• Quality: Aftermarket replacement, not OEM Greenworks. Reported 4.0/5 average rating – generally reliable, but some users note slightly shorter lifespan than genuine Greenworks batteries.
• Installation: Simple – slide battery onto tool until it clicks. No tools required. Ensure contacts are clean before first use.
• Common gotchas: May not fully charge in older Greenworks chargers if firmware is outdated. If the charger blinks red, try a newer 40V charger. Not compatible with 60V or 80V tools. Do not store fully discharged for long periods.
• Runtime: 6.5Ah provides roughly 60-90 minutes of mowing on a 20-inch deck (depending on grass conditions), about 50% more than a 4Ah pack.

Should You Buy It

Buy this if you need a high-capacity backup or replacement for your Greenworks 40V G-MAX tools and want to save money over OEM pricing. It’s ideal for medium to large yards where longer runtime between charges is critical. Avoid if you require OEM reliability for heavy commercial use or have older chargers that may not be compatible.
