what’s the difference between AA and AAA and other batteries? Why do we have a bunch of different ones?
In: 58
Your cylindrical alkaline batteries all have the same voltage. AAA, AA, C, D are all 1.5 V. They have the ability to satisfy higher current (draw) the larger they get. If you could adapt a C battery to a device requiring a D cell, it would still run but it might not run for very long. Small devices typically don’t require much current, so the battery can be made smaller, allowing for a reduction in size of the device.
