Is it safe to use the generic Li-Ion batteries for smart phones? If it is Li-Ion will it explode or will the firmware on the battery prevent it from exploding? I don't mind if the battery dies within a month, as long as it doesn't explode upon heavy draining. If there is a chance of it exploding, is there a way that I can test it out before putting it into my phone? Example is leaving it in the charger for long excessive periods. I'm am thinking about buying a extra battery for the Galaxy i9000. The reviews to the battery seem to be ok but you never know.
