Robot mower drains its battery unusually fast and returns to charge much more often than before.

Safety first: Turn OFF the mower before inspecting mechanical parts.

• Check battery age: If the battery is several seasons old, it may have naturally lost capacity and require replacement.
• Inspect for drag: Ensure wheels and blade disc spin freely without resistance.
• Charge fully: Leave the mower on the station overnight and verify that it indicates a full charge.
• Operate in moderate temperatures: Battery performance drops in cold weather; schedule mowing during warmer parts of the day.

If runtime remains very short, replace the battery pack with a Greenworks-approved replacement.
