Each person in his life at some point takes out a battery from a non-working device and wonders what kind of model it is. Where to get a similar one? Most often, this problem occurs with tablet batteries such as the LR44. The battery, the technical characteristics of which will be discussed in this article, is quite popular. And now you will learn not only what it is capable of, but also what it is suitable for, as well as what it can be replaced with. The LR44 model is a battery whose technical characteristics are not very impressive compared to finger analogs, but at the same time its price remains within reasonable limits, and there is no alternative if the manufacturer of a particular device was counting on this particular model.
Specifications
What is an LR44? The battery, the technical characteristics of which you now know. It has an extremely small size, in which its main advantage is expressed. Its diameter is 11.6 millimeters, and its height is 5.4 millimeters. Moreover, its weight is incredibly small - only three grams. Given this, in most cases, several such batteries are required to power a particular device. Its output voltage is 1.5 V, and the nominal capacity does not exceed 110 mA / h. Accordingly, this is one of the lowest rates, which, however, is offset by a rather low price - you can buy batteries on Chinese sites for less than forty rubles. Or you can contact a specialized store where one such battery from a well-known brand will cost you 125 rubles. So, the LR44 is a battery whose technical characteristics you already know. However, what can it be used for? How great is its functionality?
Using
Many people begin to doubt when buying that such batteries can generally be used anywhere. Naturally, it is impossible to say specifically to which device it will fit until you see which batteries are used in this device. But we can safely say that today there are still quite a large number of devices designed specifically for such power sources. This model of batteries is most often used in calculators, small toys, watches and table clocks, as well as in some cameras. Of course, finger-type batteries everywhere displace this type, where they can fit in size. But illuminated key chains, laser pointers and other similar items are not where you can insert even the smallest finger-type battery. That is why you need to pay attention to how efficient and affordable the LR44 battery is. Specifications and classification are what you need to know about it before you make a purchase. You already learned everything on the first point, it's time to pay attention to the second.
Classification
Tablet batteries are a rather interesting type of power sources, since they can have different markings, but at the same time have the same diagonal and height, that is, they are completely suitable for a particular device where, for example, an LR44 battery is used. Specifications, types - this is important information, because, as it turns out, you do not need to look for a battery with this marking. Other types of batteries are also suitable. For example, LR44 can be replaced with models 303, V303, D303, LR1154 and so on. All of them have the same diameter and exactly the same thickness - the differences can be in the output voltage and rated capacity, but this does not play such an important role.
Packaging
These batteries can be purchased individually, if you find where you can make such a purchase. Most often they are sold in packs of two or four. However, the most profitable option is to order a wholesale pack of 50 pieces. The shelf life of these batteries is three years, so you need to count on this period.
