depends wat on more then a normal battery anyway
AAA is the size of the battery, there are many types and makes of AAA battery and the shelf life for each is different.
If we assume the same battery chemistry and quality, and the same drain, then the D cell will last longer than the AAA cell, as the bigger size means it'll hold a bigger amount of energy.
A AAA Duracell battery typically lasts between 3 to 5 years when stored properly in a cool, dry place at room temperature. The actual usage time of the battery will depend on the device it is used in and how frequently it is used.
If we assume the same battery chemistry and quality, and the same drain, then the AA cell will last longer than the AAA cell, as the bigger size means it'll hold a bigger amount of energy.
The battery life of Bose noise cancelling headphones that use AAA batteries can vary based on usage, but generally, a single AAA battery can last approximately 20 to 30 hours of continuous playback. Factors such as the level of noise cancellation used and the volume can influence this duration. It's advisable to use high-quality alkaline or lithium batteries for optimal performance.
21 hours is how long.I did a science fair project on it.Dollar General brand batteries last longer than 5 hours!
a AAA battery. Or a watch battery, or a AAAA battery, or any number of battery types. http://en.wikipedia.org/wiki/List_of_battery_types
roughly 1 to 2 hours
They both involve batteries.
For a set rate of power drain and the same battery chemistry, the biggest battery will last the longest. In this case, the 'C' size.
Many different battery brands include AAA batteries some examples of AAA battery brands include two of the biggest battery brands, Energizer and Duracell.
