2Pack 40V 6.0Ah Lithium ion Battery Replacement for Greenworks 40V and 29482 Charger Compatible with Greenworks 40 Volt Power Tools 29252 20202 22262 25312 20642 22272

What It Is

This is a 2-pack of 40V 6.0Ah lithium-ion batteries, designed as a replacement for Greenworks 40V cordless lawn mowers, string trimmers, blowers, and other 40V power tools. Each battery delivers 216Wh of energy, offering longer run time than standard 2.0Ah or 4.0Ah packs.

Fitment & Compatibility

Before buying, verify your tool or charger uses Greenworks’ 40V G-Max or 40V Twin Force platform. These batteries are not compatible with 60V, 80V, or 24V Greenworks systems. They work with the 29482 charger (included in some kits) and are compatible with models like 29252, 20202, 22262, 25312, 20642, and 22272. Check your tool’s battery port: it must have the standard Greenworks 40V slide-in interface (rectangular with two side rails). Measure the battery compartment—these packs are slightly larger than 2.0Ah units; ensure your mower or tool has enough clearance (approx. 6.3" x 3.5" x 3.5" per pack). They are not compatible with older 40V Ni-Cd or 40V “G-Max” tools using a different connector shape.

Key Things to Know

• Quality & Performance: These are OEM Greenworks batteries, not aftermarket. Expect consistent runtime and charge cycles (rated for 500+ cycles). The 6.0Ah capacity provides roughly 50% more runtime than a 4.0Ah pack.
• Installation: No tools required—slide battery into tool or charger until it clicks. Ensure the release latch is fully engaged to avoid drops during operation.
• Charging: Use only Greenworks 40V chargers (model 29482 or similar). Do not mix with third-party chargers—risk of damage or fire. Full charge time from empty is about 90–120 minutes with a standard charger.
• Gotcha: These batteries are heavier (approx. 1.8 lbs each) than smaller Ah packs. On lighter tools like trimmers, this can cause fatigue; on mowers, it improves traction and balance.

Should You Buy It

Buy this if you own multiple Greenworks 40V tools and need extended runtime for mowing or heavy-duty yard work. It’s ideal for replacing worn-out 2.0Ah or 4.0Ah batteries, or for expanding your fleet without buying a new charger. Skip if you only have one small tool or prefer lighter, shorter-run batteries.
