Can anyone recommend me a suppier of an original battery.

I got one from handtec.co.uk recently which at least appears genuine (though so do most fakes) and behaves correctly, e.g. the voltage and temperature sensors work. In many fakes these things are just connected to a fixed resistor so that it always reports the same voltage and temperature to the phone (though the battery % does decrease with time, the detailed information is constant).
