Decrease of Battery Life in Vostro 3500..

I have been using a Dell Vostro 3500 for almost 1.5 years now and I'm beginning to notice a significant decrease in battery life. Its now down to 1 hour 30 mins barely compared around 2 hours 30 mins which I used to get before. I do understand that battery life reduces with time but I didn't expect such a reduction in battery life within just 1.5 years..!! Please let me know how to check battery cycles through command prompt as I believe I used to know some command like 'power -cfg' to check battery cycles but now I can't remember..
