TREE.NB 40V 6000mAh Lithium Replacement Batteries 2-Pack for GreenWorks G-MAX – High Capacity, LED Indicator

TREE.NB 2-pack 40V 6000mAh lithium batteries replace GreenWorks 40V G-MAX packs to restore runtime for compatible cordless lawn and garden tools.

If your GreenWorks 40V yard tools are running shorter than they used to, this pair of TREE.NB replacement batteries offers a high-capacity Li-ion option designed to fit the second-generation GreenWorks G-MAX platform. Each battery is rated at 40 volts and 6000mAh (6.0Ah/240Wh) and includes LED charge indicators and built-in safety circuitry. The set is intended as a drop-in replacement for many GreenWorks model numbers — check compatibility below before purchasing.

Which GreenWorks models will these batteries fit?

These TREE.NB batteries are built to match the form and electrical requirements of GreenWorks 40V G-MAX second-generation packs. They pair with a wide range of model numbers but are not compatible with first-generation batteries or certain mower-specific packs.

• Compatible with: 29472, 29462, 2901319, 24282, 24252, 21332, 25322, 20672, 2101602, 20312, 24322, 21362, 26272 and other listed G-MAX second-gen part numbers.
• Not compatible with: first-generation GreenWorks 40V batteries and specific mower type MO40L02 (21-inch mower) models.
• Always verify the shape and connector layout on your existing battery before ordering.

How long will these 6000mAh batteries run my tools?

Runtime depends on tool type, load and operating conditions; higher-capacity cells generally deliver longer run times than OEM lower-capacity packs. The 6000mAh rating indicates more stored energy than many stock 40V cells, so you should expect extended operation between charges in similar-use scenarios.

• Higher capacity (6.0Ah) provides more runtime versus smaller packs.
• Actual runtime varies by tool (blower, trimmer, mower) and workload.
• Use the onboard LED battery indicator to monitor remaining charge during use.

What safety and convenience features are included?

TREE.NB packs include built-in battery management to protect against common electrical faults and help preserve cell life. The housing incorporates cooling vents and a snap-fit connector for straightforward installation and removal.

• Onboard microchip offers overcharge, overcurrent, short-circuit and self-discharge protections.
• Four-LED fuel gauge shows approximate charge level at a glance.
• Ventilation holes in the case aid passive cooling during heavy use.
• Standardized snap-in design aligns with GreenWorks second-generation tool latches.

How do I charge and maintain these replacement batteries?

Charge with a compatible 40V GreenWorks charger; follow standard Li-ion storage and charging guidelines for longest service life. Avoid extreme temperatures and store at partial charge if you won’t use the batteries for extended periods.

• Use only chargers rated for GreenWorks 40V systems to ensure proper charging profiles.
• Store in a cool, dry place and avoid heat sources or freezing conditions.
• Remove batteries from tools when not in use and recharge before long-term storage if recommended.

Who is this for? This TREE.NB 2-pack is intended for homeowners and landscapers who need extra runtime or quick swaps for GreenWorks 40V second-generation tools. It’s a practical option for anyone who owns compatible GreenWorks blowers, trimmers, hedge trimmers, chainsaws or similar cordless tools and wants higher-capacity replacement cells with basic safety and status features. Confirm your tool’s model number and connector type before purchasing to ensure a correct fit.
