AA Battery vs. AAA Battery: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 7, 2024
AA batteries are larger and generally have a higher capacity than AAA batteries, both being common types of cylindrical dry batteries.

Key Differences

An AA battery is a standard size of dry cell battery, commonly used in portable electronic devices. The AAA battery, while similar in function, is smaller in size compared to the AA battery, making it suitable for smaller devices.

Both AA and AAA batteries can be either single-use or rechargeable, with the former being disposed of after use, and the latter can be recharged and used multiple times. The AA battery, due to its size, often has a longer lifespan in both single-use and rechargeable forms compared to the AAA battery.
