What is the meaning of AAA in battery?
The AAA battery (or triple-A battery) is a standard size of dry cell battery. One or more AAA batteries are commonly used in low-drain portable electronic devices. A zinc–carbon battery in this size is designated by IEC as R03, by ANSI C18.
Are all AAA 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.
Are AAA batteries the same as 1.5 V?
For example, an alkaline battery, like a AA or AAA, has a nominal voltage of about 1.5V, while the voltage of a LiPo battery will usually be around 3.7V….Nominal Voltage.
| Chemistry | Alkaline or Zinc-carbon |
|---|---|
| Battery Size | AA, AAA, C, and D |
| Nominal Voltage | 1.5V |

How long does a 9V battery last in use?
Conclusion. Even with an “expensive” Lithium 9V battery, an Arduino-based project will only last for 1 or 2 days of continuous use. As a side note, a handful of AA (LR6) batteries will last 4-5X longer than their 9V counterparts.
What are 9V batteries used for?
A nine-volt battery, either disposable or rechargeable, is usually used in smoke alarms, smoke detectors, walkie-talkies, transistor radios, test and instrumentation devices, medical batteries, LCD displays, and other small portable appliances.
