I thus assume that they would be safely interchangeable. However, do voltage and amperage have to be the same to be safe? I would suspect that a higher voltage would wreck the laptop or battery, as with a higher amperage. I don't have a great knowledge of power, however. These are my guesses; could you please verify each and elaborate? I'd like to learn why something is good or bad.
Do both the input and output specs have to match the criteria? Or is only the output important? Practically, you need the same voltage for a correct charge. But it's not that simple.

Check the adapter first with a voltmeter to verify that it's providing the proper amount of energy as specified.
Try the adapter on each laptop with and without the battery installed, as in some cases the battery can prevent the computer from seeing the adapter when it's connected. Update your operating system and BIOS if necessary to help your laptop see the new hardware. Verify that the adapter jack is not loose or broken, causing a weak connection.
