Batteries like LR03 are one of the most popular and everyone has seen them. These are pinky power sources. The name arose because of the typical size of all galvanic cells with the designation AAA. They belong to the alkaline class, while depending on the design, some of the bottom can be charged, with others, such manipulations are impossible.

Specifications LR03
All batteries in which the name indicates the lettering AAA are related to pinky batteries. In their size and shape, they resemble this particular part of the human body, galvanic cells with this name have the same appearance.
At the same time, the type of chemical element may vary. The model under consideration has a chemical battery, alkaline.
The ANSI NEDA standard name is 24 A. The batteries may have different names, but if AAA and LR are indicated, then they are definitely suitable for the device. The main characteristics of the shape, weight and size:
- length - 44.6 mm;
- diameter - 10.5 mm;
- weight - 12 grams (the weight may vary slightly from different manufacturers).
Since the main scope of this type of battery is powering electronic devices of various sizes, including portable, remote, the importance of capacity is maximum in comparison with other alkaline models. So, the main technical parameters of the battery:
- rated electrical voltage - 1.5 Volts;
- capacity - from 250 to 1200 mAh.
Attention! It is important to determine which device you need a battery for. If we are talking about gadgets that are used less often, then the capacity can be selected medium or even minimal. But for those devices that are used daily, you should choose battery options, the capacity of which is from 1000.

Battery Applications
LR03 are used to power a variety of devices used in everyday life. In this case, the technique is small and consumes a relatively small current. Among these devices, the most famous:
- remote controls for TV, VCR;
- portable digital audio players;
- modern cameras without battery;
- pocket sized radios;
- Kids toys;
- wireless devices and more.
The battery provides the necessary electric charge. Moreover, the self-discharge coefficient is relatively small.
Battery Analogs LR03
Analogs are all AAA batteries:
The battery voltage is 1.5v, while the battery is 1.25v or 3.7v. Increased damage to the device can be burned.
It is worth noting the most famous battery models: Duracell Turbo MAX LR03 12bl, Duracell Professional LR03 mn2400, Energizer LR03 MAX12 72, GP Super Alkaline 24a LR03.
Can I charge the LR03 battery
If it is an alkaline battery, then you cannot charge it, since it is not a battery. It is a completely different matter if this is a li-ion power cell, then it can be charged using special chargers. Of course, the cost of the latter will be significantly higher.
Popular manufacturers and their features
The best ratios in terms of price and quality for power supplies from Duracell, Energizer, GP. Such batteries have a high energy intensity, long life and low self-discharge coefficient. However, not only these models deserve attention.
Also pay attention to the options of manufacturers:
- Trophy
- Robiton
- Space
- Varta;
- Panasonic
- Camelion
- Alkaline;
- Sony
- Daewoo;
- Samsung Pleomax.
What to look for when purchasing
The higher the battery parameters indicated, the better. This is not to say that the higher the cost, the better the model. Frequently and inexpensive batteries show high quality. When choosing, pay attention to:
- capacity;
- voltage;
- power, voltage;
- shelf life;
- self-discharge coefficient.
A lot of batteries marked AAA LR03 are on the market today. It is important not to forget about the guarantees of the manufacturer. If they are maximum in terms of time, then this means that you can return the goods with factory defects or get your money back.
