A:AnswerAs a heavy gamer the charge only lasts about 4 -5 days but it all depends on usage. As for the batteries themselves? I have one original Xbox 360 battery that is over 6 years old that I'm still using, but the other ones have lasted a couple of years at least. Keep the terminals clean on the back (I use rubbing alcohol & a QTip) and you will extend their life.
