I ordered this battery to replace the old battery (original) from my BlackBerry device, 3 years old and no longer held any of the load. This is exactly the same: not equivalent, not a copy - the same as the original. An original part. Here I go again for three years of using my old BlackBerry! In times of crisis, the fight against obsolescence programmed by replacing some of its phone to a more than reasonable price, this is the ideal ... rather than buying a phone fluff, super modern, but falling out after two years and which we can not change the battery.
