I do not know if it's me who have a problem with the batteries but every time the handset my phone falls (fortunately this is rare), there is a battery that remains introuvable.Du shot, you better have Reserve because the one that loses has to go to a very distant and definitive journey because I never found! | O |. I say this but my mother, very dizzy she has also repeatedly dropped her phone and her home, too, there was always a stack disappears and remains so strongly advises introuvable.Je to those who have good understanding problems with batteries to vengeful spirit :) The price is also very affordable.
