Frequently Asked Questions

How long should a Greenworks battery flash green while charging?
A Greenworks battery typically flashes green for 30-60 minutes during normal charging, depending on the battery capacity and how depleted it was. The light should turn solid green when fully charged.
What does it mean when my Greenworks mower battery flashes green but never turns solid?
If the green light flashes continuously without turning solid, it usually indicates the battery isn't reaching full charge due to dirty contacts, temperature issues, a faulty charger, or an aging battery that may need replacement.
Can I use my Greenworks mower while the battery light is flashing green?
No, a flashing green light indicates the battery is still charging and should remain in the charger. Only use the mower when the light turns solid green, indicating a full charge.
Why won't my Greenworks battery charge and just keeps flashing green?
Common causes include dirty battery contacts, extreme temperatures, a faulty charger, or an old battery that's lost its ability to hold a full charge. Try cleaning contacts and ensuring proper temperature before considering replacement.
How do I know if my Greenworks battery charger is working properly?
A working charger should show a solid red light when first connected, then flash green during charging, and finally show solid green when complete. If it doesn't follow this pattern or makes unusual noises, the charger may be faulty.
