The 6.0 Ah battery provides approximately 45 minutes of runtime, suitable for lawns up to 1/2 acre or less, depending on grass conditions and cutting height.
5. Maintenance
Regular maintenance ensures optimal performance and extends the life of your lawn mower. Always remove the battery pack before performing any maintenance.
5.1 Cleaning the Mower
