Futurebatt 24V Battery Replacement for Greenworks 6.0ah 24 Volt Lithium Lawn Mower Battery 29842 29852 LB24A020 for Greenworks Trimmer Weed Blower

What It Is

This is an aftermarket 24V 6.0Ah lithium-ion battery replacement designed to power Greenworks 24V cordless lawn mowers, trimmers, weed blowers, and other tools in the same battery platform. It’s a drop-in replacement for the OEM Greenworks 29842, 29852, and LB24A020 batteries.

Fitment & Compatibility

• Check model numbers: Works only with Greenworks 24V tools that accept the slide-on battery pack (rectangular shape with side rails). Compatible with models like 29842, 29852, LB24A020, plus many 24V trimmers, blowers, and mowers (e.g., 24062, 24252, 24282, 24322).
• Deck size irrelevant: Battery size is the same regardless of mower deck width (16” or 20”); just ensure your tool uses a 24V slide-pack, not the 40V or 80V platform.
• Measurements: Approximately 5.5” x 3.5” x 3.5” (same as OEM). Verify your battery compartment isn’t damaged or warped before buying.
• OEM vs aftermarket: This is third-party (Futurebatt), not Greenworks. It may not charge in all Greenworks chargers—test compatibility with your specific charger model.

Key Things to Know

• Capacity: 6.0Ah matches OEM, but real-world runtime may be slightly less (aftermarket cells often have lower discharge efficiency). Expect 30–45 minutes on a mower.
• Installation: No tools needed—slides directly onto tool. Ensure locking tabs click firmly; loose fit can cause power loss.
• Charging: Use only a Greenworks 24V charger (model 29462 or similar). Avoid third-party chargers—they can overheat or damage the battery.
• Common gotcha: Battery may arrive partially charged. Fully charge (2–3 hours) before first use. If it doesn’t fit, check for debris in the battery slot or bent contacts.

Should You Buy It

Buy this if you need a budget-friendly spare or replacement for a Greenworks 24V tool and don’t mind slightly shorter runtime than OEM. It’s fine for light lawn work (small yards, trimming) but skip it if you need maximum runtime or heavy-duty use—stick with a genuine Greenworks battery for reliability.
