What It Is

This is a 2-pack of 40V 6000mAh extended-capacity replacement batteries for Greenworks 40V tools. Designed for longer runtime on mowers, trimmers, blowers, and other 40V equipment—ideal for larger yards or heavy-duty tasks.

Fitment & Compatibility

• Voltage & Chemistry: 40V lithium-ion. Not compatible with Gen 1 Greenworks tools (check your tool’s battery port: Gen 1 uses a flat-top connector; this fits the newer slide-in design).
• Compatible Models: 29252, 20202, 22262, 25312, 20642, 22272, 29462, 29472. Also fits most Greenworks 40V tools from 2015 onward (verify your tool’s model number).
• OEM vs Aftermarket: Third-party replacement. Not made by Greenworks. May lack some OEM safety features (e.g., over-discharge protection).
• Physical Check: Measure your existing battery—this pack is slightly larger than standard 2Ah/4Ah models. Ensure it fits your mower’s battery compartment without obstruction.

Key Things to Know

• Quality: Mixed reviews. Some users report shorter lifespan than OEM (1-2 seasons vs 3-4). Check for swelling or overheating after first few charges.
• Installation: Trivial—slide onto tool until it clicks. No tools needed. Charge with any Greenworks 40V charger.
• Gotchas:
  • Not for 60V or 80V tools.
  • May not work with older Greenworks mowers (pre-2015) even if voltage matches.
  • Extended capacity adds weight; expect ~1 lb more per battery than standard 4Ah.
• Warranty: Typically 30-day return window from seller. No manufacturer warranty.

Should You Buy It

Buy if you need affordable extended runtime for multiple Greenworks 40V tools and are okay with shorter overall battery lifespan and no OEM support. Skip if you want guaranteed compatibility, longer durability, or have Gen 1 tools—stick with genuine Greenworks batteries.
