6000mAh Replacement for Greenworks 24V Battery Compatible with Models 29842/29852/LB24A020/BAG709 Perfect for Lawn Mowers, Trimmers, Chainsaws & All 24V Cordless Tools

What It Is

This is a 6000mAh replacement battery for Greenworks 24V cordless tools—lawn mowers, trimmers, chainsaws, blowers, and other 24V outdoor equipment. It’s a higher-capacity aftermarket alternative to the original 2Ah or 4Ah packs, designed to extend runtime.

Fitment & Compatibility

• Exact models: 29842, 29852, LB24A020, BAG709 (and any Greenworks 24V tool using the same slide-on battery interface).
• Check before buying:
  • Measure your existing battery’s length/width (approx. 6.5" x 3.25") and confirm the slide rails match.
  • Verify your charger’s voltage—this battery only works with Greenworks 24V chargers.
  • Not compatible with 40V, 60V, or 80V Greenworks tools.
  • If you own a 24V mower, ensure the battery compartment is deep enough for the 6000mAh pack (it’s slightly taller than 2Ah/4Ah packs—about 4.5" tall).

Key Things to Know

• Capacity vs. runtime: 6000mAh gives roughly 50% more runtime than a 4Ah pack and triple a 2Ah pack—good for mowing a 1/4-acre lawn on one charge.
• Installation: Drop-in replacement, no tools or modifications needed. Slide on until it clicks.
• Quality note: Aftermarket battery—cells may not match OEM longevity. Check for overheating during fast discharge (e.g., heavy mowing).
• Common gotcha: Some users report the battery indicator lights are less accurate than OEM; don’t rely solely on them for remaining charge.

Should You Buy It

Buy this if you have a Greenworks 24V tool that’s out of warranty and you want more runtime without paying OEM prices. Skip it if you need guaranteed long-term reliability or if your tool requires a genuine battery for warranty coverage.
