There have been a few people confused as to what a manual 901 battery adapter is and it's purpose. The adapter is made to be used as an extension to the 901 battery so it can fit the main (home) charger properly, without jamming the manual button. These pics are on my website also:
Paul,
I would like to mention that the 901 battery adapter is useful in preventing the scratches you get by screwing the auto batteries into the charger over and over. We just leave the adapter in the charger for both manual and auto batteries. Also saves the connector in the charger from a little wear and tear.

Wish I could take all the credit for the extension. I found a manufacturer who offered the extensions. I had run into forums discussing this issue and found a solution before I began to carry the 901 manual batteries.
I am looking into the unflavored juice, not sure if I will carry that high of mg.
Good point Rocket!
Very true, I also leave the adapter in the socket. May also be useful in preventing the battery screws from breaking off in the main charger. I had a friend here locally tighten his batteries in the wall charger and had it break off in the charger when he went to unscrew it. Now that I think about it, this happened to the wifey also.
