I just bought the rechargeable battery pack for the xbox 360 wireless controllers.(only one, not with charger). Once i inserted it into two of my wireless controllers, it never turned on.Does the battery pack need to be charged even though i just bought it?points to whoever has the solution
For any rechargeable batter, you must charge it before using it. This is because rechargeable batteries have a sort of memory in them. That's why you also have to wear rechargeable batteries all the way before you charge them to get the most out of them.
