40V Lithium-Ion Battery Replacement for Greenworks 40V Battery Compatible with Greenworks Battery 40Volt 29462 Cordless Power Tools

What It Is

This is a 40V lithium-ion battery replacement designed for Greenworks cordless lawn mowers, string trimmers, blowers, and other 40V power tools. It provides a drop-in power source for tools that originally use Greenworks 40V batteries like the 29462 model.

Fitment & Compatibility

Before buying, confirm your tool uses the Greenworks 40V platform (not 60V or 80V). Check the battery port shape—this battery fits all Greenworks 40V tools with the standard slide-in interface, including mowers, trimmers, and chainsaws. It is an aftermarket replacement, not OEM Greenworks. Measure the battery compartment dimensions (roughly 5.5 x 3.5 x 2.5 inches) to ensure it fits your tool’s housing. It will not work with other brands like Ryobi, Kobalt, or Ego.

Key Things to Know

• Quality variance: Aftermarket batteries often have lower capacity and shorter lifespan than OEM Greenworks batteries. Expect 2-3 Ah typical capacity (check listing for specifics).
• Installation: Simple slide-in and click—no tools required. Ensure it locks firmly into place before use.
• Charger compatibility: Works with standard Greenworks 40V chargers (model 29472 or similar). Do not use with 60V/80V chargers.
• Performance: May run 10-20% shorter runtime than an equivalent OEM battery, especially under heavy load or in cold weather.

Should You Buy It

Buy this if you need a budget-friendly spare battery for light-duty use like trimming or small lawn mowing, and you’re okay with slightly shorter runtime and potentially shorter overall lifespan compared to OEM. Skip it for heavy commercial use or if you rely on maximum runtime—spend more on a genuine Greenworks battery for better reliability and warranty support.
