My starter hardly turns over anymore. I tried a new battery with no luck.

Question

I first switched batteries with a known good one and it turned over like it should. After driving it for a day it still would just barely turn over. Later the I charged the battery and it turned over like it should but loose power later. I would assume that the alternator is going out but I have the normal voltage reading and I don't have a check engine light. Could this be some other problem?
