X220, 9 cell battery

I had a battery  (the original one) for about 2 years of usage. About three weeks ago from nowhere, the battery had crash, from 6 hours of  working the time split in half and in one week, he give failed completely. I just bought a new one from an online shop from my country. I hadn't formatted it yet (let to make a fluctuation from 0 to 100%), but I used it and sometimes my laptop is closing from nowhere.


I would like to know if there is a problem with my laptop or with my charging...


The battery model is 42T4940.  Technology Lithium Ion. I'm using windows 7 and linux OS.
