This is a spare controller I own. I'm always mindful of battery degradation, so I charge it about once a month, and I don't think there's any battery damage. Since this is a spare controller, I hardly ever use it. I've used it only a handful of times, so it's in extremely good condition. There are, of course, no functional problems whatsoever. I haven't flipped it over because the thumbsticks are intact, but the underside is as clean as the top. There's a security sticker on the box, and there are traces of it having been peeled off. Please consider this equivalent to having no box. The charging cable, etc., is unopened and included. Thank you.
