What It Is

This is a 2-pack of 6000mAh 40V lithium-ion replacement batteries designed for GreenWorks cordless lawn mowers, string trimmers, blowers, and other 40V power tools. Each battery provides extended runtime compared to the standard 2Ah-4Ah packs, ideal for larger yards or heavy-use sessions.

Fitment & Compatibility

Before buying, confirm your tool uses GreenWorks’ 40V G-MAX or 40V Twin Force platform (not 80V or 24V). These batteries replace models 29472, 29462, 2901319, 24282, 24252, 21332, 25322, 20672, 2101602, 20312, 24322, 21362, and 26272. They physically fit all GreenWorks 40V tools that accept the standard slide-in battery pack (common on mowers, trimmers, and blowers from 2015 onward). Do not assume compatibility with other brands (e.g., Ryobi, EGO, Kobalt) – the slide-in design and voltage are unique to GreenWorks. Measure your existing battery’s dimensions (approx. 5.5 x 3.5 x 2.5 inches) and verify the terminal layout matches. These are aftermarket replacements, not OEM GreenWorks.

Key Things to Know

• Runtime vs. weight: 6000mAh offers roughly 1.5-2x the runtime of a standard 2Ah GreenWorks battery, but adds ~0.5 lbs per pack – may feel heavier on handheld tools like trimmers.
• Installation: No tools needed – slides directly into the battery port. Ensure the locking tab clicks fully; loose fit can cause power loss mid-use.
• Charger compatibility: Works with any GreenWorks 40V charger (standard or rapid). Do not use with non-GreenWorks chargers – risk of damage or fire.
• Quality note: Aftermarket batteries may have slightly shorter lifespan than OEM (200-400 vs. 500+ cycles). Check for overheating during fast charging – unplug if hot to the touch.

Should You Buy It

This 2-pack is a good value if you need extended run time for a large lawn or multiple 40V tools and are comfortable with aftermarket batteries. Skip if you prefer OEM reliability for heavy commercial use or have an older GreenWorks tool (pre-2015) where terminal fit may be inconsistent.
