The battery seemed used or dummy because the hologram sticker seemed a little wrinkled. Then when I loaded the laptop with this battery, everything has become very hot, hot inquiétantement. Then the cell was working on the first day. . . but sometimes was extinguished spontaneously. Then the day 2md, the battery is dead. 100%. She did not accept any load. Fortunately, she did not kill my laptop (my old battery of six years remains usable.)
