Hi there,

Go back and start the checks from the beginning, make sure that the charge rate is between 13V & 14.5 V check the terminals are clean and tight, load test the battery for a faulty cell, and if that is all ok, have a current draw test done, this will show any circuit that is drawing battery current when it should not, start here.
