Dell Inspiron 3593 battery replacement

I got a Dell Inspiron 3593 i7 laptop but the battery does not even last an hour on full charge. The battery capacity of the laptop should be enough to keep up with the specs integrated, however the battery hardly lasts an hour. I don't even do gaming or use any power-demanding application on my laptop. How much does it cost to change the battery for Dell Inspiron 3593.
