Useful but perhaps a tad overpriced?,
This review is from: Official Microsoft Xbox 360 Rechargeable Battery Pack (White) (Video Game)
If you are using a wireless controller and find yourself forever replacing the batteries, then you might like to consider this.
In conjunction with the quick charger kit, this battery will be fully charged in ~2 hours (for a single battery) or ~4 hours (for two in the charger at the same time). This then gives around 20 hours of play, which is pretty good.
However, for what is essentially a NI-MH battery cell, it is expensive - especially when you consider the quick charger kit comes with a battery as well and is only a third more expensive. Having said that, it's easier, faster and perhaps cheaper than using normal rechargeable NI-MH AA batteries.
The alternative is the play and charge kit, but either you need to plan it in advance or have the wireless controller connected to the console for a period of time - kinda defeating the object of it being wireless in the first instance!
