is this just the alternator or another problem ?

has anyone had trouble with the battary intermitantly charging, or the battary light comes on and the battary flatens, somtimes all the lights come on then the power steering turns off for just a second, then turn off the engine and the battary is flat, started up again using a power pack and starts to charge its ok for a wile the happens again the next trip any ideas ? also tried new battery still happens but the older battery still holding charge. car is a c3 2004 1.4 petrol engine with lots of mileage.
