SANIU 8.0Ah 24V High Capacity Battery Replacement for Greenworks 24V Battery BAG708 29842 29852 LB24A020 2983102 Long Runtime Compatible with Greenworks 24V Tools Lawn Mower Trimmer Blowers (2 Pack)

What It Is

This is a high-capacity 8.0Ah 24V lithium-ion replacement battery pack (2-pack) designed for Greenworks 24V cordless tools, including lawn mowers, trimmers, and blowers. It offers longer runtime than standard 2.0Ah or 4.0Ah packs, making it ideal for larger yards or extended use.

Fitment & Compatibility

• Direct replacements for: Greenworks BAG708, 29842, 29852, LB24A020, 2983102, and all 24V G-Max tools.
• Check your tool’s voltage: Must be 24V (not 40V or 80V). Look for “24V” on the battery port or tool label.
• Physical fit: Same slide-on form factor as OEM Greenworks 24V packs. Works with all Greenworks 24V mowers (e.g., 25312, 25142), trimmers (e.g., 21142), and blowers (e.g., 24242). Not compatible with 20V or 40V Greenworks tools.
• Measurements: Approx. 5.2 x 3.1 x 2.4 inches per pack; weight ~1.2 lbs each. Verify your tool’s battery compartment has clearance for the slightly taller 8.0Ah pack.

Key Things to Know

• Runtime: Delivers up to 4x the runtime of a standard 2.0Ah battery (e.g., 60+ minutes on a mower vs. 15–20 minutes). Expect 2–3 hours on a trimmer/blower.
• Installation: Snap-in, no tools required. Charge fully before first use (use any Greenworks 24V charger, not included).
• Quality: Aftermarket replacement; not OEM. Uses high-grade 18650 cells with overcharge/short-circuit protection. Some users report slightly shorter lifespan than OEM after 1–2 years.
• Gotcha: May not fit tightly in older Greenworks 24V tools (pre-2015) due to minor molding differences; check for secure lock-in before use.

Should You Buy It

Buy this if you have multiple Greenworks 24V tools and need extended runtime for a large yard or heavy trimming, and you’re comfortable with an aftermarket battery at a lower price than OEM. Skip it if you want guaranteed OEM fit/longevity or need compatibility with older 24V tools only.
