Right out of the box, I was able to put the batteries in the Nyko charge station and get the charge running. I have read many complaints online about having the batteries that come with the Nyko Charge Station for Xbox 360 dead on arrival, making it impossible to charge unless with a separate cable. I encountered this problem later on, when returning from vacation, that the battery would not charge. After leaving the battery in the charger for a couple hours, it suddenly sprang back to life. This unreliable charging with the Nyko Charge Station makes it hard for those who do not play for several days and an inconvenience for those who just want a quick game.
On the first few days of using the battery with the Nyko Charge System for Xbox 360, it gave average times of around 20- 25 hours at most. This is considered good for a product not created by Microsoft. However, after a month or two, the battery life began to drop noticebly. While this may be okay for those who play for less than an hour every day, it becomes a chore recharging the batteries over and over again. Presently, I receive around 8-10 hours per charge from the Nyko Charge Station, which is not acceptable to my standards.
With an unreliable charging system and a decreasing battery life, the performance of the Nyko batteries and Nyko Charge Station are below average and not suitable for those who play for more than a few hours.
