I had tried just before the battery equivalent brand Anker, who was not truly compatible, my pc does not recognize (Toshiba Satellite A300), impossible to know the time to charge and discharge virtually instantaneous short I ... have returned and my choice fell on it which, for now, does not disappoint me at all! Fast charge time, battery life of approximately 1h30-2h, which is more than correct. I'm satisfied.
