    Ok. So Im sure there is an obvious answer to this question but I have looked everywhere and cant find one.

    What is the difference (excluding size) between AA, AAA, C, and D batteries? If I am correct the all produce the same 1.5v. In other words why use a D cell over a C cell? Or better yet why not always use AAA cell so that items may become smaller?

    Anyways, like I said Im sure there is an obvious answer for this stupid question but after looking for a while, Im still curious enough to ask.

    Battery Life? Just a guess. Larger batteries can sustain a heavy draw for longer periods of time? Just a logical thought.

    Yeah, of all the reasons I could come up with I considered battery life to be the most plausible one.

    Yeah, the difference is in the milliamp-hours (how much amperage the battery can put out for how long). The larger the battery the higher the mAh rating typically is.

    Maybe it is the amperage? the bigger batteries seem to be used in devices that draw more power..
