| AA battery | AAA battery |
|---|---|
| Usually, last long hours due to its storage capacity | Runs out of faster due to its size |
Are all triple A batteries the same?
AAA batteries differ greatly in chemistry and hence they differ in capacity, voltage, current/voltage discharging characteristics, and many other features, which may be of great importance when powering sensitive electronic equipment.
Is there such a thing as AAA battery?
AAAA batteries exist, though are used only with very, very thin devices like penlights. A size batteries are hard to find as well. In fact, I can’t even find a picture of one, because they were primarily used in really old laptop batteries.
