Xbox rechargeable battery

[rocky slate]

I bought this Xbox controller and I also bought this rechargeable battery from the same place and once in a while something is rattling in it? Is that normal?

What is the battery for?

The rattling is most likely the modules banging on the casing because they're not fixed inside properly

If you don't rattle it too much, it'll live

if the battery is rattling it is not normal

if something in controller is rattling as long as it is not way too much it should be fine

my xbox controller rattles a bit if you shake it
but also it is legit from 10 years ago
