FirstPower Replacement for Greenworks 40V Battery 6.0Ah Lithium 29472 29462 - Compatible with 40v Greenworks Battery Tools 24252 25322 20262 29252 20202

What It Is

This is an aftermarket 40V 6.0Ah lithium-ion battery designed to power Greenworks 40V cordless lawn mowers, trimmers, blowers, and other tools. It replaces OEM models 29472 and 29462, offering higher capacity than standard 2.0Ah or 4.0Ah packs for longer runtime.

Fitment & Compatibility

• Voltage & Chemistry: Must be 40V lithium-ion (matches Greenworks 40V system). Do not use with 24V or 80V tools.
• OEM Replacements: Directly replaces Greenworks 29472, 29462, and similar 40V slide-pack batteries.
• Tool Compatibility: Works with Greenworks 40V tools like 24252, 25322, 20262, 29252, 20202. Check your tool’s battery port – it uses the standard slide-in tab design.
• Physical Check: Measure battery compartment depth (approx. 5.5” x 3” x 2.5”). Ensure charger is 40V Greenworks (not 80V or older 24V).
• Aftermarket Note: Not OEM – fitment may vary on very old Greenworks models (pre-2015). Test fit before forcing.

Key Things to Know

• Capacity vs. Weight: 6.0Ah gives ~50% more runtime than 4.0Ah, but weighs ~1.5 lbs more – may feel heavier on handheld tools.
• Charger Compatibility: Works with Greenworks 40V standard chargers (e.g., 29472, 29502). Not compatible with rapid chargers unless specified.
• Build Quality: Aftermarket; some users report slightly shorter lifespan than OEM. Avoid deep discharge – recharge when tool slows.
• No Installation: Just slide in until it clicks. No tools needed.

Should You Buy It

Yes, if you own multiple Greenworks 40V tools and want a budget-friendly high-capacity battery for longer mowing or trimming sessions. Skip if you need guaranteed OEM reliability for heavy daily use or have very old Greenworks models with tight battery ports.
