    What is the difference between a 1.5 volt AA and 1.5 AAA battery? Does anybody know?

    Thank you all for the help. The greater capacity of a AA Battery would mean that it would take longer to charge, right?

    No, the charge rate is usually a multiple of the capacity. Higher capacity batteries can be changed with more current. For example if a battery can be charged at 1C then it will take a bit over 1 hour to charge it no matter what its capacity.
