TP2 and Mogul Battery Interchangable?

[timsmooth]

Hello all, this is my first time posting to the forum. I have a question about the TP2. I just noticed that the TP2 and the Mogul have the exact same batteries. Well at-least visibly they resemble each other. Does this mean they are interchangeable like my belt holsters is (lol). If so I think I have found a battery dock for my TP2. If not Mogul is sold. The mogul uses a battery OEM model 6800 and the TP2 uses a OEM model 6875. Same voltage and MH, but still I do not want to start a fire. Has anyone tried using them interchangeably. Thanks in advanced.
