The battery fits into the device and gives you enough energy again. He does not clean on my MD96350 with the chassis as the original battery pack. Since there is only minimal and I the back eh not so often look at myself, I think it overlooks the universal use of batteries for different laptops and the cheap price reasonable. The battery was delivered quickly. And for 20 euros can not do much wrong. So the in the tooths laptop is again donated enough energy. Time will tell if the battery of the life also produces a good product.
