Ok, my 510 PCC just arrived. I have the 510 manual however, I am having the darnedest time trying to connect the batt to the PCC. There seems to be a wide space which is the only way to place the manual battery however there seems to be some serious spring action and the battery does not connect to the terminal. I have tried turning the battery slightly once inserted but there doesn't seem to be a built in slot for this batt to turn (manual switch).
What am I doing wrong?
Thought I'd pass this thread along to you:

Yah; I had the same issue & when I purchased a back up PCC, that one fits and works like a charm. But, there might be some other information in there that may be of assistance.
HTH!
