I was giving your question more thought and I did notice that you said that your battery had been replaced, so let me just add this. (And this is just my opinion)
Most times, a problem such as you are having is usually a more basic problem rather than some huge puzzle. But, like most problems, sometimes things that should be simple in complexity are the ones which can cause the most frustration.
My personnal guess would be that you have one of two obvious problems. The altermator isnt charging properly or the battery itself has a bad cell. You need to eliminate these two basic possibiliies before going any further. Even though they are new. I would gather the basic tools to remove them if it were me and drive myself to autozone or somewhere where they can test them for free and remove the battery and have them test it. If it comes back fine, then do the same to the alternator. If it comes back fine as well, I'd put them back in and double check that all cables and grounds are clean and properly connected.
Now, I know you think that since they r new, this isnt the problem and you may be correct, but sometimes you can still get a faulty part and that will make trying to figure something out.A struggle because you assume thats not it. So, I'd double check them.
I have been where you are my friend many times and I can feel your pain. Maybe someone else has a more helpful suggestion but if it were me, this is what id do. And if you dont find the problem after a second looking over just to be sure, then I'd look closer at the other possibilities.
And one more thing, make sure the cable from the alternator to the battery is in good shape. Make sure no wires are worn or are touching anything they shouldnt be.
