AAA batteries: which are better, technical characteristics, classification, instructions for use

Pinky batteries, what are they called? Their second name is AAA type. The primary name came from their size, about the size of a little finger. You could say this is a popular name. And the name aaa is already scientific, classification.

In shape they resemble a small elongated cylinder. They have a characteristic colorful shell with inscriptions. The industry produces casting, salt and alkaline types. Technical characteristics and service life depend on the integrated electrode.

What are AAA batteries and what are they? This is a 1.5 volt salt battery. Used in various electronic devices that consume little energy. Similar battery-type elements may be found on sale. Their capacity is significantly higher than usual, which means that their performance will be extended due to this.

Perhaps someone thinks that aaa are finger ones, but this is not so, they are little finger ones. How is this word spelled? It is written as you see above.

AAA battery and its characteristics

Below are the technical parameters of the little finger battery, dimensions, current, voltage, expiration date and much more. This description will help you understand what this power source is.

This energy source is protected against corrosion and short circuit. It consists of equipping the battery with a plastic or metal case. The cylindrical electrode is insulated with special insulation.

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

The letter AAA on the batteries indicates their shape and size. That is, this is a kind of GOST standard. An example in the photo below!

Pinky battery designation

According to the EIC JIS nomenclature, it is designated R03. Soviet digital designation - 286.

1. The brand in this case is Energizer.
2. AAA element tim.
3. Chemistry – Alkaline or alkaline – alkalin.
4. Best before date. This power source has it until 2026.
5. Negative pole.
6. Positive end.

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

How many amperes are in a pinky battery?

As a rule, the current of such AAA batteries is not large. In this battery it can hold up to 4 amp hours.

Battery capacity aaa

It has an energy density of 1250 mAh - it is alkaline. Rechargeable AAA batteries have a capacity of 300 – 1100 mAh. Salts have 540 miles amperes per hour.

Voltage

The voltage is 1.5 v. This parameter is typical for salt and alkaline energy sources. For nickel metal hydride (Ni-MH) batteries it is 1.2 volts.

If you are wondering up to what voltage you can use AAA batteries, then look at the device data sheet.

Pinky battery size

They have the following standard sizes:

• Diameter 10.5 mm.
• Length 44.6 mm.

Element weight aaa

The little finger battery weighs approximately 12 grams.

Shelf life of pinky batteries

To find out this parameter, look carefully at the label. On some elements they write that it is 8 years. But the operating time depends on the device in which they are used. And how many micro ampere hours does it consume.

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

The body is made of metal or aluminum and a colorful label with the main characteristics is applied to it. It can also be made of paper, but this is very rare these days.

Operating temperature range

It is -40 – “+60”.

Popular models from Energizer and Duracell

Both American manufacturers have been known to Russian consumers for quite some time. In their reviews, they give preference to the two most popular models of AAA batteries: Duracell Duralock (about 200 rubles) and Energizer Extreme (260 rubles). Their technical indicators are the same: capacity 800 mAh, number of recharge cycles – 1000. Both are sold in a charged state, which indicates their low self-discharge current. And although Duracell guarantees 5 years of uninterrupted operation for its product, most likely, under the same operating conditions, Energizer will last no less. Which AAA batteries are better can only be finally determined by one’s own experience of using them, and with the same energy consumer. Otherwise, the comparison will be very incorrect.

Types of AAA batteries

The following varieties are most often distinguished.

Salt

These elements are designed for light loads. They are marked with the letter L. The duration of operation is low. The cost is also not high.

The positive terminal includes manganese dioxide with acetylene black, flake graphite or electrolyte.

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

Here's how these energy sources differ from others:

1. Low price.
2. Comfortable use.
3. Cheap and available raw materials for manufacturing.
4. Suitable for most modern electronic devices.

Disadvantages of salt batteries:

• Strong self-discharge.
• They serve for about 2 years.
• High current consumption quickly destroys the energy source.
• They do not work well at low temperatures.

Alkaline or Alkaline

They are considered average both in price and duration of work. Potassium hydroxide electrolyte is used as a filling. This allows the chemical reaction to proceed faster. The current is delivered better. Manganese-zinc chemistry can be used.

Powdered zinc is used as an anode. The cathode is manganese dioxide. Power usually reaches 150 kilowatts. Operates from -30 to + 50 degrees Celsius. Energy density from 1000 – 1100 mAh.

Advantages:

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

The disadvantage is the short service life. They may not work well in equipment that requires surge voltage.

Lithium

They last quite a long time. The internal resistance is small, this is another plus.

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

Key Features:

• Expensive.
• They work for a very long time.

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

Rechargeable AAA batteries

• NiCd (nickel-cadmium). Memory effect.
• Li-pol (lithium polymer).
• Li-ion (lithium-ion). Temperature dependent.
• NiMH (nickel metal hydride). Sensitive to overcharge.

This type is rechargeable many times over. This means that the same battery can be used several times. Simply put, she has several lives. Such elements are used in devices with high current consumption.

The selection is made based on:

1. Device.
2. Environmental conditions.
3. Brand.
4. Best before date.

The fact is that some batteries do not tolerate charging very well, others react strongly to temperature, and still others cannot be charged unless they are completely discharged.

What to look for when choosing

When choosing batteries, you should pay attention to several main aspects:

• First of all, this is capacity. The larger it is, the longer your device will naturally work before the next recharge. However, the process of restoring the functionality of high-capacity products will take longer.
• If you use the device (with batteries installed in it) quite often, then you can safely purchase standard batteries. But if you turn on the device from time to time, then buy products with a low self-discharge current. Then, when you take the flash off the shelf six months later, you can be completely confident in its performance. Conventional batteries will be discharged to zero within this period.
• The number of recharge cycles is of concern mainly to very zealous owners. Even with the minimum value of this indicator (500) and very intensive use (recharging every 2 days), the most budget batteries from GP will last for at least a year and a half.

Important! You cannot save too much on the charger, as this leads to a decrease in battery life. It is best to purchase products with an automatic shut-off function from trusted manufacturers.

The final conclusion about which AAA batteries are best for your CD player or your beloved child’s radio-controlled car can be made by carefully reading the instruction manual (which often indicates the recommended capacity) and consulting an experienced sales consultant in a specialized store.

Charger for aaa batteries

As a rule, you cannot recharge regular salt or alkaline cells. The manufacturer warns its consumer about this on the labels.

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

Only rechargeable AAA batteries can be inserted into such gadgets. Others may simply explode. But if you push the salt aaa into the smart charger, then in this case the device will turn off.

The charging time depends on the battery capacity, usually 2-3 hours.

Thus, the adapter for AAA batteries will serve well and bring the battery back to normal!

Areas of use

AAA batteries are designed for compact electronic equipment:

Correct installation of the AAA battery in the remote control.

• remote controls;
• players;
• flashlights and voice recorders;
• children's toys;
• and other low power wireless devices.

In more demanding equipment, for example, a quadcopter, AAA batteries will use up their resource quite quickly, since their power is limited by the small body.

Adapter for AA to AA batteries

A similar adapter can be purchased at any radio outlet. As a last resort, you can find it in an online store, for example, Aliexpress. Using this device, you can easily turn a little finger battery into a finger battery.

All this adapter does is increase the size of the battery. As can be seen from the figure, it is hollow and consists of two parts. Reminds me of some kind of matryoshka doll. Metal contacts are attached to each of its ends.

All you need to do is open the adapter, place the little finger battery there and close it tightly. After this, it can be used as an AA type AA battery.

Thus, aaa batteries are modifiable.

Application

Battery device

Rechargeable batteries can be found in power supplies for measuring instruments, cameras, game consoles, medical equipment, flashlights and many other household and civil products. Finger batteries can be connected in series, forming groups of several elements.

Important! In power boxes, batteries are arranged in rows. Each subsequent element is oriented with poles in the opposite direction from the previous battery

This order cannot be violated. Otherwise, the batteries may be damaged.

Power bank from AAA batteries

Little finger batteries are rarely used to create Power Banks. For the simple reason that their capacity is too small. Such a power bank will work for a fairly short period of time and therefore few people spend time on its creation.

Aliexpress has special cases with electronic filling available for creating a portable battery. The video below shows how easy it is to assemble a self-contained power supply from AA elements.

Unclear markings

And finally, let’s talk about another type of marking that manufacturers love to decorate their products with. What do inscriptions like Power+, Turbo, Super, +40%, Long Lasting Power, Ultra and the like, which do not carry specifics, mean? What does "Ultra", "Super", "Turbo" or "++" on a battery mean? Never mind. Just an addition to the brand name. For example, Hong Kongers stopped diluting the electrolyte in their GP battery with donkey urine; a new model, GP Super, appeared. Or maybe they didn’t stop, they just tweaked something or added something.

The battery is just Super!

Some inscriptions, of course, can be interpreted in some way if desired. For example, "Lasting Power" can mean high current output. Or it may not mean that. What does "Heavy Duty" mean? Heavy in what way? Are the currents large? Cold? Hot? Wet? Dry? Will they beat you? Or, on the contrary, do batteries create difficult conditions for the equipment they power?

Difficult conditions? Come to us!

Therefore, let us make it a rule - we read only what has an unambiguous and clear meaning. AA – clear and precise. LR03 - definitely. 1.5 V – of course. Duracell - no questions asked. Everything else is attributed to the development identifier and marketing, which do not promise anything and do not obligate the manufacturer to anything.

Manufacturers

The following companies produce similar batteries:

1. Panasonic ni mh hhr 55aaab.
2. Duracell aaa.
3. Trophy.
4. Philips.
5. Pleomax.
6. Xiaomi.
7. .
8. Philips.
9. FinePower.
10. Energizer.
11. Robition.
12. Minamoto.
13. Space.
14. Varta.

16. Bison

Analogues of the AAA pinky battery

1. 24A (ANSI/NEDA).
2. R03.
3. MN2400.
4. LR03 (IEC).
5. HP16 and micro.
6. UM4.
7. AM4.

Thus, you can replace it with one of the above elements.

If you want to replace 3 AAA type pinky batteries with finger batteries, then it is unlikely that you will succeed. For the simple reason that the sizes will be different. The element will not fit into the device. But the voltage is fine.

There is only one way, this is to connect three elements in series. For example, create a paper container, place energy sources there and attach two wires to the plus and minus. Then connect these wires to the device, observing polarity.

Oh horror, the date is encrypted!

Indeed, some battery manufacturers do not put an open date on the product packaging, encrypting it using their own markings.

In particular, well-known manufacturers - Duracell and Sanyo Eneloop - resort to such techniques.

In this case, readers should know:

• The first digit in the date marking almost always indicates the year;
• the second is a month;
• third - day (the number may be missing);
• the fourth is the supplier code.

For clarity, let's look at examples:

14-01SQ:: 14 - year (2014); 01 - month (January); SQ - supplier code.

9B15-LM:: 9 – year (2009); B - month (B is the second letter of the English alphabet, indicating the 2nd month - February); 15 - date (day February 15, 2009); LM—vendor code.
