Take the battery to a parts store so they can test it....
Actually you need to test both the battery and the alternator because if your alternator is not functioning correctly it can drain the battery of power...
so just testing the battery may only tell you that you have a drained battery and not reveal the cause...
This testing can be done using an Auto meter which tests the battery and also does an alternator load test...If you do not have a tester you can rent one from an auto parts store,or you can remove the alternator and take it to the auto parts store and have it bench tested along with the battery...usually for free...
