@Bhoid actually Sony said if the battery in the controller dies they will replace it for free, so you wouldn't need to open it up and replace the battery
And @Spectrumgir
Yeh they run out pretty quick I thought it was the controller broke or something but he got a second one at wal-mart and it did the same, but it's true they run out fast for him, I don't think he plays it that much but everytime I go there and we play the Xbox 360 either one of are controllers always runs out of batteries, I recommened him to buy one of those rechargeble batteries with a charger but I dont no.
