Difference between AA and AAA Batteries





Distinguish differentiates, compare and explain what the Difference between AA and AAA Batteries. Comparison and Differences.

AA/AAA Rechargeable Batteries

As the numbers of gadgets that assist our daily lives keep growing in number with each passing day, the variety of their power sources also increases. The mostly commonly used types of batteries are the AA and AAA type, which power up most of our portable devices ranging from television remotes to blood glucose meters almost all small sized gadgets rely on the AA and AAA battery types.

AA and AAA Batteries

Probably the oldest size in battery types which is made the standard. AAs are slightly larger in size when compared to AAA. They are available in various chemical constituents, which differ from each other in terms of performance and durability. Here are a few battery types and their advantages and disadvantages.

1. Lithium

Renowned for their durability, which is displayed when they work faultlessly for years but a major drawback gripping the lithium batteries to lack behind is the fact that they are non rechargeable. For some devices this type of AA/ AAA is the best for the job! Also when compared to alkaline batteries they tend to last about 7 times longer. However there is a certain type of AA Lithium ion rechargeable battery but that is rare to find in shops, this type of Li-ion is mostly not known of! Unlike Alkaline batteries they do not leak.

2. Alkaline

Alkaline AAA/AA batteries are available in rechargeable and non-rechargeable types but considering their chemistry it is more economical to choose the rechargeable type. It is recommended to avoid using Alkaline based batteries in devices with high drain that deplete the alkaline based batteries at a faster rate than its normal life.

3. Nickel Cadmium

These are the ideal choice for devices that heat up very quickly, reaching high temperatures that other batteries can’t handle. They are priced cheaply when compared to other battery types of the same voltage which makes them perfect for commercial purposes.

4. Nickel Metal-Hydride

(NiMH) work best when used in extensively used devices, because before recharging if they are fully drained out of power then they tend to last for a longer period of time compared to other battery types, for example it would be better to use them in a frequently used TV remote than a hardly used digital camera. An issue with the NiMH is the fact that in idle conditions they discharge by themselves besides this they are environmentally friendlier compared to other battery types. There are also differences between AA and AAA Batteries when they are pitched! against each other, here are a few:

Differences between AAA and AA Batteries

1. Generally, the AAA are smaller than AA batteries.

2. AA batteries tend to carry a larger amount of chemical content that AAA batteries of the same voltage size.

3. AA batteries are designed for devices that consume more power than the AAA batteries are capable of producing.

4. AAA batteries have a higher internal resistance compared to AA batteries so their maximum current output is less.

5. The general belief among battery specialists is the fact that AAA batteries generally cost more than AA but tend to deliver less in terms of power.

The AAA and AA rechargeable batteries are designed for devices with low power consumption requirements such as toys, remote control, blood glucose meters, and several other small electronics it is a wise idea to invest into expensive rechargeable battery brands as they tend to be worth their price and deliver a long lasting battery life along with several recharging cycles.

Are AA and AAA batteries classified as dangerous goods?

AA and AAA indicate the physical size of a battery, not the type. It is important to know the packing instructions in order to determine if it is classified as dangerous goods. Lithium batteries are classified as dangerous goods. Please refer to the product Safety Data Sheet (SDS) or product specifications to determine the classification of the battery type.
