What does the AAA and AA batteries mean. AAA batteries: what better, specifications, classification, instructions for use

Today, the batteries are the same product of the first need, like a toothpaste or napkins, without them there will not work the remote, night light, flashlight, calculator, clock and more. If you now sit and consider how much instruments feed on these little items, you may be surprised, almost half of the devices need to buy batteries. How often will have to be changed, depends on the competent approach to the choice of batteries. Why do the batteries of one firm work a month, and the other half of the year? The point is not even price. As a rule, in the store the buyer first looks at the form and size, maybe even on the manufacturer. Only units select batteries for chemical composition, voltage, tanks, check the expiration date.

What is a battery and when did it appear?

Battery (It is a galvanic element) is a source of electricity, which acts on the basis of chemical interactions of certain substances among themselves. The first chemical nutrition element was invented by Luigi Galvani. More precisely by the electroplating the discoverer of the process, and completely random. The scientist conducted experiments on the frog and when he connected two strips of different metals to her paw, then discovered the flow of current between them.

The discovery of Galvani served as an impetus for another scientist - Alessandro Volta, who got to the truth and gave the development of a scientific find. In the future, the initiative to improve nutrition elements picked up the company, the first of which was EveReady. The products being implemented only remotely resembled modern types of batteries, the main active substances were manganese and zinc. The first batteries for radio receivers were intended, in the future, the power supply based on chemical interaction was distributed in the machine-building industry.

In 1920, the well-known company Duracell comes to the market. Batteries apparatus apparatus applied all wider, production grew in geometric progression. The first Duracell battery was made of a zinc case with a graphite electrode and a brass cap. It was filled with manganese oxide, the walls of the zinc case from the inside were covered with electrolyte. The brass cap was positive, and the dyshko of the zinc corps by a negative pole. Such batteries were produced up to the collapse of the USSR. But in view of its drawbacks: a small service life, not a safe design, they quickly went into the past. Modern batteries with a long lifetime, safe design and high capacity, came to replace the old sample.

Modern types of batarekes

Depending on the composition and active components, the battery can be divided into groups. Each group has pros and cons.

- Salt batteries. The most budget type of nutrition elements are characterized by low current recycling, short service life and storage. At low temperatures, the container decreases much faster. The device of salt batteries is not far away from the first samples of Duracell. The electrodes are made of manganese oxide, zinc and interconnected by salt bridge. But despite all the shortcomings, consumers are still buying salt batteries in large quantities. The best way to use for salt galvanic elements is low intake devices: clock, remote control, scales. If the salt battery is left in the device and for a long time not to use the probability that it flows. This is due to the flow of chemical reactions, at the last stage of the discharge, it is characterized by an increase in the active mass of the positive electrode, which increases the pressure on the electrolyte. In parallel, the processes of decomposition of manganese dioxide and zinc corrosion processes are flowing, which entails the release of oxygen and hydrogen, the volume and pressure inside the battery rises.

- Alkaline (alkailain) batteries. Universal both at the price and by the service life of batteries that occupy a large market share. As an electrolyte, potassium hydroxide is used, from which the batteries have such a name. Alkaline batteries are stored up to five years, have a large capacity than predecessors. This species reduces the risks of leakage, the long-term temperature at low temperatures and the minimum self-discharge rate. Alkaline power elements are marked with Alkaline inscription, which is alkaline in translation. Recommended for use in devices with moderate load, such as: children's toys, night lights, radio, remote control, etc.

- Lithium batteries. Appeared relatively recently, are above the price category. With the development of all sorts of gadgets and portable devices, the demand for batteries, withsting intensive current consumption in a long period of time, began to grow. Lithium batteries meet all consumer requirements: long shelf life and service, resistance to temperatures (high and low), light weight, do not proceed. It should be noted, lithium batteries have a constant voltage and high energy consumption that no predecessor will provide. Suitable for equipment with high power consumption: lights, flashes, cameras, portable columns. Mark up on the inscription on the "Lithium" package.

Mercury and silver batteries are quite rare, although in their properties they are similar and are little inferior to lithium.

The disadvantages of mercury batteries are the unsafe of use in damage to the integrity of the design, disposal complexity.

Battery sizes

Batteries differ not only with dimensions, but shape, some are common and are widely known (AA, AAA), others have to search for a long time. Despite the abundance of forms, all batteries have a classification according to standards. The names of AA, AAA, C, D are familiar to the rumor, belong to the American standard.

There are other systems of nutritional elements classifications: international, national. In Russia, the size of the batteries are regulated according to GOST, but this type of marking is not heard and few of young people use it.

AA (finger or R6 / LR6) - Cylindrical thin batteries, are used in remote controls, clocks, toys, lanterns and other small techniques. The designation R6 speaks of the dimension of the battery, and the prefix l makes clarity that the alkaline element.

AAA (Mizinchikov or R03 / LR03) - Cylindrical batteries, thinner elements AA, but can be applied in the same devices.

C (R14 / LR14) and D (R20 / LR20) - similar in the form and size elements, compared to AA and AAA, very cumbersome and heavy. Today, manufacturers rarely resort to the installation of data elements data, since the dimensions of gadgets are becoming less and more compact, the batteries, respectively, too.

Crown (6F22 / 6LR61) - This element is different from previous dimensions, shape and highest voltage 9V. Contact batteries are on the one hand. It is urgent in modern devices is extremely rare.

A separate category should include miniature batteries made in the form of "tablets". They have their own extensive marking and classification, differ in diameter, height, tank, chemical composition.

Important features

- Self-discharge. It is a loss of battery capacity for the storage period, therefore, each element has a shelf life. During the storage (without use), the battery capacity can be reduced to 30%, as much depends on the storage temperature. This is due to the slow flow of chemical processes inside the battery, i.e. The process takes place all the time, simply in operation, chemical reactions are faster, and slowly slowly into the rest. When you buy batteries, be sure to look at the date of production than it is fresh, the more the capacity corresponds to the stated.

- Voltage. Depending on the type and type of battery, the voltage is varies, which it provides. Standard voltage of budget elements of 1.5V, lithium batteries provide voltage in 3V. The most powerful element should be considered a crown, the voltage is 9V.

- Capacity. The indicator that determines the number of "electricity" with the battery, the battery life of the battery directly depends on the tank. How to calculate battery life time?

For calculation, it is important to know two parameters: a charge and consumed current. Suppose the battery charge of 3 Ah and it is installed in a device with a current consumption of 250 mAh (0.25AH), we calculate how many hours the battery will work: 3 Ah / 0.25 Ah \u003d 12 hours.

The actual service life may not coincide with the calculated reasonable causes:

The temperature of the outer environment

Self-discharge

Modes use

Cutching current

Let's sum up

Many manufacturers indicate the packaging for which devices is suitable for the battery. But what to do if the scope is not specified? We select the battery depending on the purpose of use:

Salt Power Elements It makes no sense to install in devices outstanding high power: professional lights, flash cameras. In devices with medium loads, salt elements will also last long. It's all about small capacity, only 600-700 mAh.

Alkaline batteries are also not suitable for powerful lighting devices, but for a long time they will last in all other gadgets, ranging from the music column and ending with a children's train.

Lithium nutrition elements are suitable for any device, but it does not always make sense to buy an expensive element. The optimal choice for frequent use instruments.

Important: just throw away the spent battery in the trash can not right!

On the package or case, the designation is always present - not to throw together with domestic garbage. If you have a reception point in your city, then do not be lazy to make the world a little cleaner.

Mizinchiki batteries What are they called? Their second name AAA type. The primary name went due to their size with the little finger. It can be said is the folk name. And the name AAA is already scientific, classification.

In shape they resemble a small cylinder elongated form. Have a characteristic colorful shell with inscriptions. In industry make injection molding, and alkaline types. Specifications and duration of operation depends on the integrated electrode.

What is aaa type batteries and what are they? This is the salt supply element with a voltage of 1.5 volts. Used in different electronic devices consuming little energy. Such elements of the battery type can be found on sale. They are significantly higher than usual, which means that performance due to this will be extended.

Perhaps someone thinks that AAA is, but this is not the case, they are mizinechik. How is this word written? It is written as you see above.

AAA battery and its characteristics

Below are the technical parameters of the Misinchchik Power Element, the size, current, voltage, shelf life and much more. This description will help figure out what is this power source.

This energy sources have protection against corrosion and short circuit. It consists in equipping the battery with a plastic or metal case. Cylindrical electrode is isolated with special insulation.

A positive end is made in a video of a small cylinder occupying about a third of the entire diameter. The negative pole resembles a flat sometimes relief area. The dimensions are most often the same, but the weight varies a bit due to the use of different chemistry.

An alphabet inscription AAA on batteries speaks of their form, sizes. That is, this is a certain GOST standard. An example in the photo below!

Misinchic battery designation

According to the Nomenclature of EIC JIS, it is denoted by R03. Soviet digital designation - 286.

1. Brand in this case.
2. Tim element AAA.
3. Chemistry - or alkaline - Alkalin.
4. Shelf life. This source has it until 2026.
5. Negative pole.
6. Positive end.

Thus, the marking of a memorial battery shows partially characteristics that are reflected in the following sections.

How many amperes in a memorial battery?

As a rule, the current in such elements of the power supply of AAA is not large. In this battery, it may contain up to 4 amps of hours.

Battery capacity AAA

It has an energy density of 1250 Mah - it is alkaline. Aaa type rechargeable batteries have from 300 - 1100 mAh. Possess 540 miles ampere per hour.

Voltage

Voltage is 1.5 V. This parameter is characteristic of salt and alkaline energy sources. In nickel-metal hydride (Ni-Mh) batteries it is 1.2 volt.

If you think about what voltage you can use AAA batteries, then see the device passport.

Misinchic battery size

They have the following size:

• Diameter 10.5 mm.
• Length 44.6 mm.

AAA element weight

Misinching element weighs about 12 grams.

The shelf life of mizinechiki batteries

To find out this option, look carefully on the label. On some elements they write that it is 8 years old. But the performance time depends on what device they are used. And how much he consumes micro amp hours.

Frost-resistant AAA batteries are nickel-cadmium. But this is already a battery type.

The case is performed from metal or aluminum and a colorful label with basic characteristics is applied to it. It can also be made of paper, but similar in our time is highly rare.

Operating temperature range

Is -40 - "+60".

Types of AAA batteries

Most often allocate the following varieties.

Salt

These items are designed for a small load. They are marked with the letter L. Low functioning. The cost is also not high.

The positive pole includes manganese dioxide with acetylene soot, scaly graphite or electrolyte.

The negative pole is created from a strong zinc with cadmium elements, gallium, and sometimes lead.

This is why the data sources of energy differ from the rest:

1. Small price.
2. Comfortable application.
3. Cheap and affordable raw materials for manufacture.
4. Suitable by parameters to most modern electronic devices.

Disadvantages of salt batteries:

• Strong self-discharge.
• Serve about 2 years.
• Much current consumption quickly removes the source of energy.
• Do not work well at low temperatures.

Alkaline or alkaline

They are considered to be centered for both the price and the duration of work. The electrolyte of potassium hydroxide is used as the filling. This makes it possible to flow chemical reaction faster. The current is given better. A manganese-zinc chemistry can be used.

Powder zinc is underway as an anode. The cathode is manganese dioxide. Power usually reaches 150 kilowat. Work from -30 to + 50 degrees Celsius. Energy density from 1000 - 1100 mAh.

Benefits:

• Good.
• Comfortable use.
• Weak self-discharge.

The lack of service can be attributed to the lack of service. Can work badly into equipment where the hopping voltage is required.

Lithium

Serve long enough. Internal resistance is small, this is another plus.

Anode is lithium. The cathode is a different kind of electrolyte.

Key Features:

• Expensive.
• Work for a very long time.

This type of batteries may have a capacity of up to 1300 mAh. They are considered the most optimal in their class.

AAA batteries

• NICD (nickel-cadmium). Memory effect.
• Li-POL (lithium-polymer).
• Li-ion (lithium-ion). Temperature are dependent.
• NiMH (nickel-metal-hydride). Sensitive to reload.

This type is a lot of multiple rechargeable. This means that one and the same battery can be used several times. Simply put, she has several lives. Similar items are used in devices with high current consumption.

The choice is performed based on:

1. Device.
2. Environmental conditions.
3. Brand.
4. Shelf life.

The fact is that some batteries are not very well tolerated charging, others are strongly reacting to the temperature, but the third cannot be charged if there is no complete discharge.

Table of types of Mizinchiki Batars AAA

Charger for AAA batteries

As a rule, it is impossible to perform the recharge of ordinary salt or alkaline elements. On the labels, the manufacturer warns its consumer about it.

AAA batteries with the charger are shown in the figure below.

Only AAA can be inserted into such gadgets. Others simply may explode. But if you push the salt AAA into an intelligent charging, then in this case the device will turn off.

The charge time depends on the battery capacity is usually 2-3 hours.

Thus, the adapter for AAA batteries will serve a good service and lead the battery to normal!

AAA Battery Adapter in AA

This adapter can be purchased in any radio point. In extreme cases, you can find in the online store, for example, to Aliexpress. Using this device, without problems, you can turn the mismatch battery in.

All that makes this adapter this increases the size of the battery. As can be seen from the figure it is hollow and consists of two parts. Reminds some kind of nesting. Each of its end is attached metal contacts.

All you need to do is open an adapter, put a little battery and closed tightly. After that, it can be used in quality.

Thus, AAA batteries are modified.

Battery holder AAA

Such a device is used to fasten the battery in the device. It consists of a plastic case with various marking signs. On the edges there are flat and spring contacts. In different directions, the wires of black and red are departed from them.

AAA Battery Container

Boxes, compartments or storage cassettes or carrying are commonly used plastic type. Have a lid and a hermetic device.

Below are several similar cases.

What batteries are more aa or aaa?

Power elements by the type AAA size is less. Large are AA.

Batteries AA and AAA difference

So, what are these batteries differ?

The main criteria by which can be distinguished by mizinechiki batteries from finger:

• Marking on the housing.
• Size, little girls.
• Capacity, AAA will be lower than AA.

How many misminkers are batteries

The cost of nutrition elements varies quite strongly. So, for example, in the DNS online store for October 2018, you can purchase a set of 2 batteries from 79 p and above. For Doselovsky brand take 200 p 2 pcs.

Power Bank from AAA batteries

Misinchchinchiki nutrition elements are rarely used to create Power Banka. For the simple reason that they are too small. It will work such a sufficiently small time and therefore few people spend time on its creation.

Aliaxpress has special housings with electronic filling to create a portable battery. In the video below, it is shown how to simply collect an autonomous power supply unit of AA elements.

Misinchinchiki photo batteries

This section presents photos of AAA type batteries.

The most popular battery formats include those that are classified as AA and AAA. What are their features?

Facts about batteries AA

The relevant AA standards are considered to be batteries having a diameter of from 13.5 to 14.5 mm and a length of 50.5 mm. They are unofficially referred to as "finger". AA format batteries are considered among the most common in the world. They are produced since 1907.

AA batteries have a cylinder form, which, as a rule, is made of metal and covered with a shell. Plus and minus conclusions are located on the ends of the case. The diameter of the first - 5.5 mm, height is about 1 mm. The second conclusion is flat and includes a contact pad with a diameter of 7 mm.

The AA battery voltage is about 1.5 V. It can be noted that the corresponding format of the Ni-CD type accumulators, as well as Ni-MH, have a smaller indicator (1.2 V), and the Ni-Zn devices are greater (1.6 V ).

Depending on the type of electrolyte used in batteries, their weight differs. So, among the easiest - salt elements (about 14-18 g), a little harder - alkaline (about 22-24 g), but the batteries weigh more. For example, the mass of nickel-metal hydride elements is about 30 g.

In addition, the type of electrolyte affects the battery capacity. So, the corresponding indicator for alkaline devices is 2980 mAh, almost as much as the nickel-metal hydride batteries (their capacity is 3000 mAh). Salt batteries have a capacity, as a rule, within 1,500 mAh.

Facts about AAA batteries

To the corresponding type of batteries, it is customary to belong batteries having a length of 44.6 mm and a diameter of 10.5 mm. They weigh the order of 12. AAA batteries are informally referred to as "Misinchiki".

The elements of the type of type under consideration have a voltage of 1.5 V. The corresponding battery format - 1.25 V. Salt Battery Resource AAA reaches about 540 mAh. Alkaline tank - up to 1200 mAh, nickel-metal hydride batteries - up to 1250 mAh.

Comparison

The main difference between AA batteries from AAA - size. The first is more noticeable. This predetermines their higher capacity (if you compare the items in which the same electrolyte is used). But the voltage of both types of batteries is issued, in principle, the same.

After examining what is the difference between AA and AAA batteries, reflect the conclusions in the table.

The technologies of the modern world seek minimization and lack of wires. This leads to the fact that there are more and more different devices and fixtures that are used to power the AAA batteries. Such devices are in the house of almost each of us. These are wireless mice, shaving machines, TV and DVD control panels, pocket voice recorders, audio players, etc.

The batteries "AAA" because of its small size are often called "Misinchik" or "ministers". The following notation can also be used to label the batteries of this type: LR3, R3, LR03 (IEC) and R03. When choosing for your gadget, you must first pay attention to the type of electrolyte used, since the capacity, duration of operation and the ability to recharge.

Depending on its composition, the usual batteries "AAA" are divided into salt, alkaline (alkaline) and lithium.

In which the saline electrolyte is used, it is designed for low loads and used, as a rule, in hours, electronic thermometers and remote consoles. They are the cheapest and short-lived. It is possible to distinguish them from another type by the absence of the L in labeling, for example R3, R6, and low cost (as mentioned above).

Alkaline (alkaline) AAA batteries occupy an intermediate place. As an electrolyte, they use potassium hydroxide and this is the main difference from the salt elements. Chemical reactions in such sources occur with greater speed. This contributes to the best current. They serve as longer and suitable for equipment with an average level of energy consumption: audio players, PDAs, radio receivers, etc. You can distinguish them from another type by the word "alkaline" and the presence of the letter L in marking.

Lithium batteries AAA type are considered the best. They have the smallest and long service life. They are profitable to use in devices with intensive energy consumption: toys, LED lamps, etc.

If the device is used quite often, the accumulator batteries of the AAA type will be an excellent alternative to "minidal" alkaline and lithium elements. With the help of a charger, such sources can be recharged on average about a thousand times. The battery capacity is usually indicated in amps clock. Distribution Currently received the following types of such elements:

• Li-POL (lithium-polymer);
• Li-POL (lithium-ion);
• NiMH (nickel-metal-hydride);
• NICD (nickel-cadmium).

Each of them has its own characteristic features. Thus, NiMH batteries are very sensitive to reload, and lithium work also depends on the voltage and temperature. Sources of type NIMH and NICD have the so-called "memory effect", which consists in reducing the capacity when charging the non-fully discharged battery. In addition, for these two types, a noticeable self-discharge is characterized, that is, the charge loss even in case of idle when the device is turned off. Cadmium batteries, although they have low energy intensity, well withstand frosts and are able to withstand even

Therefore, the choice of the AAA type power source is completely dependent on the device in which it will be used, and the conditions of future work. The same when buying an item, you need to pay attention to the brand and the shelf life.

Thanks to modern technologies, the need for wires is becoming less and less. To make the device, the AAA type batteries are used. They are also called "Misinchikov" because of a small size. They are in every home and provide uninterrupted functioning of a computer mouse, shaving machine.

AAA type batteries

Manufacturers produce batteries having such characteristics:

• 44.6 mm long;
• diameter -10.5 mm;
• weight is 12 g;
• battery voltage - 1.5 V;
• the format of the batteries that correspond to them - 1.25 V;
• the capacity of nutrition elements depends on their type. The saline it is equal to 540 mAh, alkaline - 1200 mAh, nickel-metal hydride - up to 1250 mAh.

AAA batteries - what better?

Users, thinking about acquisition, wonder: AAA batteries - what better? When buying, you need to explore the characteristic features of each type:

1. Salt- Designed for low load, the letter L in marking is marked. Common devices to which they are suitable - watches, electronic thermometers, remote consoles. Elements of this type of low price is the lowest, but also less durable.
2. Alkaline - are medium price and service life. In this case, the electrolyte is potassium hydroxide, which is why the chemical reaction proceeds faster, therefore the current return is better. They are purchased for audio players, PDAs and radio receivers. An identification mark is the word "alkaline".
3. - put in first place. They are more durable and have less resistance. They are acquired for toys, just burning a large amount of electricity.

When the device is used daily and long, that is, it makes sense to apply AAA batteries. Their attractiveness is explained by the fact that using the charger can be recharged several times. Multiple types are available:

• some poorly carry recharge;
• others are sharply reacting to the temperature during use;
• thirds are not recommended to charge if complete discharge has not occurred.

The choice is made on the basis of the type of device, the terms of use, the value is given to the brand and the expiration date.

AA and AAA batteries - the difference

It is not easy to figure out a huge assortment. First of all, the AA and AAA batteries are studying - the difference that lies in the amount. Elements of AA are significantly superior to AAA in dimensions. With almost the same voltage, they have a greater container. In this case, their composition includes the same electrolyte.

Those familiar with the elements of nutrition from the user's position may be the uncommon, which means AAA on the battery. In this way, its size is indicated. In addition to this labeling, there is a second one that can also be found is the designation R03, which also confirms that it relates to the Misinchik.

After studying all the necessary characteristics, you can make your choice with regard to the features of a certain type of battery. To do this, you need to decide for what device it is planned to be applied.
