AAA batteries are most often used in small electronic devices, such as TV remote controls, MP3 players and digital cameras. Devices that require the same voltage, but have a higher current draw, are often designed to use larger batteries such as the AA battery type. AA batteries have about three times the capacity of AAA batteries.
For example, a 12V battery rated at 100Ah would have a charge capacity of 1200Wh (12V x 100Ah). Meanwhile, a 3.7V battery rated at 3000mAh would have a charge capacity of only 11.1Wh (3.7V x 3000mAh). So while the 3.7V battery has a higher mAh, the 12V battery can actually store much more total energy.
