I have a Honda EU3000is that is a little over 10 years old. Many years ago when the original battery died, I never replaced it and just used the pull rope to start the generator. I taped the battery wires so they wouldn’t touch anything with the battery gone. I read another post here of someone's (Generac) electronics getting fried by running the generator with the battery removed. I’m wondering if I should purchase a new battery to install. So far it has worked fine when I do the monthly test runs with load applied. My generator has no bluetooth or CO detector, just the low oil shutdown.
