AA or AAA battery, what is the difference between these batteries?
Today, energy supply is one of the most essential components of our daily lives. The exponential multiplication of electrical objects that accompany our activities forces us to constantly have different means of power to meet our most common needs. Even if batteries tend to take a more and more important place, batteries remain a simple and efficient way to power all kinds of electrical objects.
In fact, small electrical equipment, which only requires small amounts of energy, is often powered by batteries. They come in all sizes and powers. AA and AAA batteries are the most common because their power and storage capacity, relatively large for their size, correspond perfectly to the needs of the most common electrical objects. Here is an article on the difference between these batteries, the AA or AAA battery.
The characteristics of the AA battery
AA batteries, sometimes called LR06 batteries, come in the form of a cylinder and are common in all homes. They come in different models and can be alkaline or lithium. The latter format is tending to develop because it is more powerful, although alkaline batteries are still the most widely used. They have the advantage of being more durable than saline batteries, even if they are a little more expensive to buy.
They have a voltage of 1.5 Volts and an intensity of 2.8 Ampere/hour. This last quantity corresponds to the quantity of current supplied in one hour by the batteries. Choosing between the AA or AAA battery on a specialized site like RS Components, is therefore like selecting a power. Indeed, the AA battery develops a higher intensity, which allows it to meet the needs of small devices but relatively energy-consuming as digital cameras or alarm clocks for example.
AAA batteries are sometimes lithium based.
The characteristics of the AAA battery
AAA or LR03 batteries provide a voltage of 1.5 volts, equivalent to that of their AA cousins. The difference in size (the AAA battery is smaller) is in the amperage. Here, we have an intensity of 1.25 A/h, which reduces the amount of current provided by these batteries compared to their colleague previously mentioned. Thus, we find AAA batteries in smaller devices such as electric toothbrushes, clocks or remote controls.
Whether AA or AAA, they are also frequently found in homes. AAA batteries are sometimes lithium-based, which means they last up to seven times longer, but alkaline batteries are still the most common because they are less expensive. Provided you choose brands known for their quality of finish, alkaline batteries are quite efficient considering their price, even if the future of the battery seems to lie in lithium.
AA or AAA battery, a trick to save money!
If the AA or AAA battery provides the same voltage, their packaging is different and therefore produces batteries of different sizes. However, in absolute terms, these two sizes could power equivalent devices. So, if the AA or LR06 batteries in one of your items run out and you absolutely need to use them, there is a simple trick to power them with AAA batteries until you buy new ones.
Few consumers think to buy batteries when shopping, which can be a problem if you’ve just bought your child a toy and the batteries aren’t included, or if your office work requires a remote control, for example. In this case, insert a AAA battery into the AA battery compartment and place a piece of conductive material, such as aluminum, to make electrical contact with the second terminal. As if by magic, your device will return to normal operation!
