I don't know what "turf" the OP has, but electric mowers ain't gonna 'cut it" down here! Sometimes it's hard for gas powered mowers to get through.
By a Honda mower (not just Honda engine) you will buy once and cry a little but they are the best walk behind mower for homeowners
As mentioned, batteries WILL die and replacement costs more than the tool it self
My lawn is a Bluegrass and Fescue mix. At this time, I have a top of the line Toro.
Great mower, but I would like to get away from the noise and upkeep of a gasoline fueled engine.
Best,
Gary
I understand wanting to get rid of gas mowers, believe me!
For your size lot and type of grass and only 3 months of growing season

An electric should do fine.
I got rid of my gas leaf blower and went with electric cord powered as I really only do the driveway (about twice a week!) It's a Jungle out there!
I would go with the lease expensive as all the batteries are made you know where!
