What does AA and AAA batteries mean?
The letters indicate the size, in height and width, of the battery. For example, “AA” means “50.5mm x 14.5mm.” The letters originally began with A and progressed upward in size. But in the 1950s, electronic equipment miniaturized, and suddenly AA, AAA and AAAA battery sizes were required.
Is aa bigger than AAA?
The most obvious difference between AA and AAA is its size. The AA cell battery is slightly longer than the AAA battery and is also somewhat wider. The C cell battery is larger than the AA battery, and the D battery is larger than the others. Battery size determines the amount of current available.
