Battery works perfectly - only stars, as you will not be warned that the battery has oversize.

I ordered the battery. This all worked well, the battery is displayed initially. 4 hours duration. The then has the not fulfilled, but I have run the notebook with I7 processor, UMTS stick and external monitor multiple applications - which then requires more power. But anyway it is probably as about 2.5 - have maintained for 3 hours (exactly I have not checked). The conclusion would be that the battery well so far fulfilled its purpose.

As described by the customer in advance - unfortunately is not in the text, that the battery has oversize. This means it is difficult, and the computer then STEST wrong (behind where the battery is higher than the front). I had already read the review of another customer, does not bother me. On the contrary, I had problems because my 3 year old Vostro 3500 always had overheated and simply ran out. By raising the back of the computer seems now to be better able to attract the air and he no longer overheated. Am therefore fully zufieden. But there are clients who would disturb the (battery heavier, larger computer is then back ehöht), there is only 4 stars.
