I bought a brand new car battery and it has completely died two times in two weeks. The alternator is perfectly fine. When I turn on the car sometimes it has a very low voltage, other times it has a perfect voltage. Sometimes when it is low after driving it will suddenly raise to normal voltage. If I get out of the car and wiggle around the - the voltage will sometimes go up, sometimes not. I am not sure at all what is wrong because I have had the battery and alternator tested multiple times over the last few days and they always say good.
