Battery Pack

[HBKfan28]

I need a new battery pack. Does anyone have a generic battery pack like this one that can say if it works or not?: http://www.amazon.com/Rechargeable-..._6?s=videogames&ie=UTF8&qid=1339625458&sr=1-6

It has 5 stars on Amazon, but I know these 3rd party/generic cheap ones are hit or miss.

Iv never used an aftermarket battery back, but when i worked at Gamestop i sold quite a few and never had any come back.

Thanks, its only 5 dollars so even if it breaks its worth trying, I just want to make sure it doesn't screw up the controller or system.
