if a battery has a bad cell it wont hold a charge, but it could also be the alternator or the plug, i had a problem with the plug and had to change it from a junk yard, but before you do that i would check the easy parts first i.e the battery,then the cables, then the tension of the alternator belt, and finally the alternator itself along with the pigtail get a volt meter and test the current while the car is running, if it reads 13 to 14 volts the alternator is working and if it reads bellow 12 it is the alternator or plug. aojedamCheck your battery, it might be worn out and not able to hold a charge from the alternator.
Have you checked the alternator?
