I really appreciate my EU3000is or whatever the name is... after killing one battery for the electric key start, I treated it to a battery tender. I may be mentioned this before in this thread and apologies if I did, but I think this was the best thing I could do. Now I don't have to worry so much when I am away traveling, as my better half can easily start it during power outages.
My real-world friends are used to hearing me (not totally) joking about buying a Model T next...... but I have to admit - most people find electric start really convenient. With many people today you'd have to put some time into explaining just how/when to properly use the choke - some people have physical limitations that preclude pull-starting, or just struggle with it too much to volunteer to start something manually. Electric start solves a lot of problems, and modern batteries don't need much for maintenance, mostly just a maintenance charger like you used....... easy-peasey to do.
