I use HWINFO64 to get information about notebook's components. There is information about battery wear level. It is a percent of battery capacity which have been lost:
batteryWear = 100% - (currentMaximumCapacity/originalMaximumCapacity) * 100%
Two weeks ago that was just 35 percent. Today 6 hours ago it was 66%, now it is 74.7%. I got 71% of battery left and 27 minutes left to work on it.

It is exacly one month and 10 days till 2 years passing from buying this notebook.(bought 16-10-2012).
Can I fix it somehow using software tools? Is it just manufacturer forcing me to buy new notebook? Is it going to blow up?
