When buying an extra battery that is able to rely on it in case that the device would be used during an entire photo output, well no it is not possible with this one, because we saperçoit that although loaded before departure, it is as empty as the one we wanted to replace and there farewell pictures. I have only one advice: forget this little brand that you create problems, certainly the Canon batteries are of a higher cost but I understood why at my expense. The one I Original (3 years) still works perfectly and capacity has not fallen.
