This is not just a bad/cheap battery! It is a COUNTERFEIT! (or at least the one I received in November of 2010 is).My G9 has stopped working and the people repairing it have told us that this battery is to blame.It sends too much power through the camera and makes the cameras circuit board swell, eventually ruining it.My next step will be to contact Amazon in the hopes of preventing other people from ruining their cameras.
