this third party battery be a perfect fit in all four of we wireless controller as well as the Microsoft fast charger . recharge time and length of useable time be similar to that of the Microsoft battery . while some reviewer have complain about battery that do not fit , I have to question why they do not send they back at that time . Amazon will exchange a defective product with free return shipping . at one third the cost of the Microsoft brand battery , these be a bargain .
