    CR1632 (3v) vs. Two AA's




      Kind of a newbie at this, so forgive me if this is a stupid question, but if I've got a small lifeline alert pendant transmitter that normally runs on a CR1632, can I replace it with two AA's?  Are there any disadvantages? Do CR batteries last longer, have more capacity than AA's?


      On a separate note, if I want to replace the batteries with a power supply, can I use a 5v USB supply or would I have to look for a 3v supply?
