Recently my car started to die randomly but would start with a jump without problem. Took it to a shop who replaced the positive battery cable (heavy corosion). It worked for a few days, then the same problem arose, and another shop said the battery failed the test so I replaced the battery. It worked fine for about a week and the same problem happened. It seems like the battery will intermittently not charge/hold a charge. Sometimes there will not be enough charge to start after turning the car off, sometimes it will die while driving.

The latest incident happened a couple days after I replaced the spark plugs and spark plug wires, but I didn't think the two were likely connected.

The alternator has been tested and passed by 3 different places, but could it still be a bad alternator?
