Hello. Several things can be causing this. Have your battery load tested. Most battery sellers do the load test for free. If it is good, then check the alternator output with a meter on the battery terminals. The meter should read 13-14 volts at idle. If it is reading less than 12, it is not working properly; you will need to have a qualified technician test your battery, and determine if it is bad for certain. Other possible problems could stem from corrosion on the battery terminals and cables; this is usually a white color.
