Frequently Asked by Distributors:
Is the GW29462 a replacement for the Greenworks 40V G-MAX 29462 battery?
Yes, the GW29462 is a direct replacement for the G-MAX 40V platform. It is compatible with model 29462 / 29472. It is a drop-in replacement battery for Greenworks 40V mowers, leaf blowers, and string trimmers.
What is the MOQ for the GW29462 replacement battery?
The standard MOQ is 100 units for the GW29462. You can get paid samples of 1–10 units to check that the BMS-handshake is working before placing an order to produce something. We can make private-label or custom-specification products starting from 500 units.
Is the GW29462 drop-in compatible with original Greenworks chargers?
Yes. The GW29462 BMS is updated with specific software so it works correctly with real Greenworks chargers. It charges, shows fuel levels, and prevents accidents in the same way as the original equipment manufacturer’s charger. Handshake is validated on 100% of units at the end of the line.
Are these Greenworks replacement batteries any good?
Yes. Our GW29462 uses high-quality cells from leading brands like Samsung, LG, Panasonic, and BAK. These cells are matched in capacity and resistance, and their performance is validated by a battery management system (BMS) for 100% of units. It is made as a professional-grade Greenworks replacement battery, not a low-cost copy, and is backed by a 12-month warranty.
Will Greenworks replace my battery under warranty — and how is your GW29462 different?
Greenworks’s own warranty covers genuine packs through their service channels. We are an independent factory that supplies new GW29462 replacement packs. These packs are a direct, lower-cost alternative when a pack is out of warranty or you need a large supply. They have full UN38.3 / IEC 62133 / CE documentation.
Do you replace the cells in my old Greenworks battery?
We supply complete, ready-to-use GW29462 replacement packs — we don’t offer cell replacement or rebuild services. A new pack with fresh Grade-A cells and a fresh BMS is far more reliable than replacing the cells in an old Greenworks battery, and it comes with full safety documents.
Can I use an 80V battery on a 40V Greenworks tool, or vice versa?
No, the Greenworks 40V G-MAX and 80V Pro are different platforms. They have different voltages and latches, so they cannot be used interchangeably. The GW29462 is made to work with the Greenworks 40V G-MAX platform. Make sure the voltage of the battery matches the voltage of your tool.
What cells and configuration does the GW29462 use?
The GW29462 uses high-quality 18650 cells (2000mAh each) arranged in a 10S2P configuration for a nominal 40V and a true rated capacity of 4.0Ah. Before assembly, cells are matched based on their capacity (±20 mAh) and internal resistance (±5 mΩ). You can specify your preferred cell brand (Samsung, LG, Panasonic, or BAK) when you place your order.
What is the warranty on the GW29462?
All GW29462 replacement packs have a 12-month warranty against manufacturing defects. Every batch of products is shipped with the following documents:
– UN38.3 test report
– IEC 62133 certificate
– MSDS
– CE Declaration of Conformity
These documents are needed to clear customs worldwide.
