Hardware Switch Lite AC Adaptor/Battery help

[IndividualCarry1]

First I apologize for this being so lame, I am obsessive compulsive and am having a serious issue (for someone with OCD as bad as me). I have 2 switch lites (a turquoise and a grey) having just bought the grey one 2 days ago. Yesterday I mixed up their ac adaptors and dont know which one goes with what system. I am completely aware that it doesn't matter and that they will work with either one. But again I am OCD and its driving me up the walls. Is there a way to tell which adaptor is for which system? The adaptors are slightly different and come from different factories (have different logos on bottom and the adaptors have slightly different finishes). If I open one of the switches, will the battery have anything on it to indicate which charger it uses? Would it have the same logo as the adaptor if it was from the same unit? I'm grasping at straws here and hope someone can help.
