It takes just shy of an hour to mow ours, and the 7.5ah battery will only last the entire time if the grass is dry and not overly tall. I have a 4.0ah battery that we use to finish if necessary.EGO advertise their push mower’s run time at 60 minutes at light load with 7.5 ah battery. Or as low as 20 minutes with heavy load with 5 ah battery.
You live in the desert?
Both still hold a good charge after 2 summers of use.
