In other words the charging system is not keeping the battery fully charged. You can recharge the battery yourself and see if it will hold a charge and if not replace it yourself or take it to an automotive shop and have them test it for you.However it could be a bad Alternator causing the battery problem or the battery clamps may be corrowded and in need of a good cleaning.You could also check the Alternator Voltage output, if you have the right equipment and know how. Or take it to a shop and have them check it out for you. Good Luck.and have a good XMASS.
