I currently have a Xbox 360 Elite and 4 wireless controllers and 3 rechargable batteries. I've had them for several years now but never really use them often much. However when I do, I'm having issues with them keeping charged. What will basically happen is I will turn on one of my controllers with one of the rechargable batteries installed, but instantly it will start showing red indicating the battery is low. So I'll plug it in with the play and charge cable, and suddenly it'll say the battery is already fully charged. However if I unplug it, it will only remain on for about a minute before it just completely shuts off on me. I plug it back in, and it'll show on my 360 that it's a low battery, but it'll then show it's fully charged after a few seconds.
I've found that this seems to happen among every controller I have and every battery I have. However what's odd is I seem to have one battery and one controller that will work totally fine together. But I try using the other batteries with the controller, or use that one working battery in another controller, it runs into the same problem. Does anyone know if this is either a problem with my controllers, batteries or even both? I wouldn't want to go out and buy a new controller, only to find out it's the battery and vice versa.
