Yes. Fits mine perfectly. A little tight with the handles installed but it fits fine.
I bought this cover and a XP10000E generator for a friend, so I believe your XP13000E would fit with this cover.
Yes the XP8500E generator would come with a battery; and if you're looking for additional batteries for the unit we have them available to order through 844-DUROMAX.
No, the cover is there to protect against the weather, ect. The generator has hot exhaust gases that will burn/melt the cover and start a potential fire.
this cover will fit XP 10000 E XP 12000 EH and XP 12000 E
Yes the cover is an excellent fit.
measure generator. check dimentions in the ad or company your ordering from. worked for me.
can you this cover while it is operating
