timely delivery and packaging parfait.je relive since the acquisition of this battery; I went from one hour of battery life to more than 4 hours. I was surprised about the size of the battery do twice the original, but it's my fault, I did not read the description and in addition it has a non-negligible advantage, the computer and raised 3 cm and thus cools much better ... I board this battery if you want to find a real autonomy wallows portable.
