Look, you're making this way more complicated than it really is. There are only two components to this problem: the battery, which needs to hold a charge, and the alternator, which needs to _generate_ a charge. One of those two isn't functioning. Find out which.
Our guess, based on what you're telling us, is that the alternator is at fault. Once the engine is started, it takes very little battery power to keep it running and driveable, especially in daylight when your lights aren't on. If the alternator is doing nothing, you can still drive a long time on battery power alone, but the battery isn't getting replenished. You won't notice this until the next time you try to crank the starter.
Even if the alternator is putting out enough voltage to push the voltmeter up to 13 or wherever, it may not be generating enough amperage to handle charging the battery. Again, you won't find that out until the next time you try to start it.
So: Pull the battery and have someplace do a proper charge and load test on it. At the same time, pull the alternator (it'* _not_ difficult and you can probably puzzle it out with a couple of wrenches, even if you don't have a manual, or a garage to work in), take that in _with_ the battery, and have an output test done on it. AutoZone is one place that offers both these services for free, and probably most other auto-parts places will, too.
In the unlikely event that both of them test out fine, you've got a slow drain somewhere in the car and we can tackle that if things get that far, but my bet is that the alternator is the culprit here. If you need more help getting the alternator out, let us know.
