AA batteries produce potent currents than AAA batteries. AA batteries are costlier than other kinds of batteries, but they are stronger batteries with longer durations.The 9 volt batteries have a prism like shape whereas AA and AAA batteries are shaped like cylinders. The 9 volt batteries have a medium length of 48 mm. The length of the AAA battery is 44.5 mm whereas the AA battery is taller, measuring 51 mm. As a rule, AA batteries should not be used in devices with lower voltage.ĪA and AAA batteries have only one electrochemical cell but you will find distinctive shapes in these cells. But, generally, AA batteries are associated with higher voltages. The voltage produced by the AA battery is reliant on the cell's strength and can vary from 4.5 to 9 volts. Voltage required with AAA batteries is 1.5V whereas with the AA batteries, different voltage versions are available. Movable electronic devices like remote controls earlier used AA batteries but now they have been miniaturized with technology and are small enough to run on AAA batteries also.
The capacity in MA.h of an AA battery is three times that of AAA battery. These batteries are employed in smoke detectors and fire alarms. The 9 volt batteries got their name because they can produce current of the intensity of 9 volts.

Typically, AAA batteries are used in devices like amplifiers, MP3 players but AA batteries are used in TV remotes, cameras, flashlights and keyboards. 9 volt batteries have the most noticeable appearance due to their broadest peripheries as compared to the AA and AAA batteries.
Heaviest are 9 volt batteries weighing in at 45.6 grams. On the other hand, the AA battery typically weigh around 23 grams. AAA batteries are the lightest of these three types.
