^ OK, good info Chuck.
Lesson learned then seems to be that the stock cable that comes with Naztech branded battery isn't identical to those being sold on ebay. I'll confirm this in a week or so...I just ordered an ebay version last night.
Your experience with the on-off button seems consistent. I didn't realize that button was an on-off since I'd been using my battery from the USB connector for 5v applications, but yesterday Drewloo corrected me and when I double checked I confirmed my battery works the same way.
Someone asked about accidental shut off of the battery, but since it requires a 3 second push and the button isn't all that easy to push in, I don't see the possibility of accidental on-off of the battery with it sitting in a gear bag.
