No, but the current battery may have a bad or intermittently shorted cell and that would cause erroneous readings at the battery. Also, I forgot to mention you should check for a parasitic draw on the system.
Get a test light. With the car off and nothing on (courtesy lights, radio etc.) Remove the negative cable from the battery. connect the test light to the cable end, touch the probe to the negative terminal of the battery. If the light comes on or glows, you have a draw in the system (which can be a alternator or regulator problem even if they are working properly) No light is what you are looking for.
