Characteristics
The main characteristics of this type of batteries is that they have a good shelf life, with a discharge of less than 1% per year and a low cost per hour of use. Compared to others, they are very cheap considering these two aspects. They have one uniform voltage discharge. In addition, they provide high stability in environmental changes, which allows them to work in a wide range of temperatures, and they have a low discharge temperature that makes them do not overheat.
They are batteries with high energy density suitable for use in many types of devices, each of which stands out for its advantages depending on the composition of each of them. In addition, they are ideal for small devices in which it would not be possible to use other types of batteries due to their size.
The best known and used
Before commenting on all the existing models, they are a must. the ones we use the most in our day to day or those that we usually use for many of the devices or devices that surround us. For example, if we want our clock to work, if we are looking for something for the scale or we have to change the computer battery. Discover which are the most used to know which one you may need when you buy a device that requires button-type batteries.
CR3032
They are batteries that are widely used by the most demanding users because they offer a high duration in use, so you may have to take much longer to load them. They weigh approximately 6.8 grams. They are widely used in control panels, clocks, LED flashlights, medical devices and other compatible appliances. You can opt for rechargeable or non-rechargeable models because you have both options at your disposal. The first ones are cheaper in the short term, although the non-rechargeable ones give you better performance if you use them a lot.
Its dimensions are 30mm wide and 3.2mm high. Its capacity is 560mAh, which means that they last a long time, longer than other models made with the same material. Although your investment is somewhat higher than in previous ones, it is worth it.
CR2032
The CR2032 are the more used in clocks, motherboards, remote controls, garage doors, scales and many other devices and in general, so they are essential in your day to day. They can get confused with the previous ones because their name is very similar, although their dimensions are different and so is their price. These are cheaper than the previous ones, although they provide somewhat less autonomy. They have dimensions of 20mm width and 3.2mm in height (they are just as tall as the previous ones), with a capacity of 235mAh.
Although its performance in use is somewhat lower, it compensates for its price, since there are currently a large number of models on the market with this name. They can also be known as DL2032, BR2032, KL2032, L2032, ECR2032, 5004LC, KCR2032, E-CR2032, KECR2032, SB-T15 and L14.
CR2025
The CR2025 are very similar to the previous ones, only its dimensions vary. Therefore, we must know that we can use them for the same uses. Thus, if you make a mistake in your order you will not have problems with them because they will be worth the same. Of course, they can last a little less. Its dimensions are 20mm width and 2.5mm high. Its capacity is 170mAh, which is lower than the previous one but not bad at all, especially considering that there are many models of them on the market and they provide you with very competitive prices.
They can also be known as DL2025, ECR2025, NA, BR2025, 208-205, DL20256B, BR2025-1W, CR2025-1W, KCR2025, L12, LM2025, SB-T14, LF1/2V and 5003L depending on the manufacturer, so if you see this name it would be the same type of battery.
CR1632 and CR2016
These two models are not the most used, but they are well known for their use in watches. They stand out for having been made in lithium and have a 3V voltage. The former have dimensions of 16mm and 3.2mm. The CR1632 have dimensions of 20mm (just like the CR2025 and CR2032), only their height is less, 1.6mm.
They are used in watches and other devices, as in the previous cases. Both can be used for cameras, remote controls, calculators, heart rate monitors and other uses. The only drawback is that its autonomy is less than the previous ones, which makes most users opt for the others, although these are a good alternative if they are cheap, there is an offer or you prefer them for some other reason. Its capacity in the case of CR1632 is 125mAh and in the CR2016 it is 80mAh. If you are thinking of acquiring them, make an assessment between their autonomy and price.
LR44 batteries
These are some of the best known because they are frequently used in smaller devicessuch as calculators, measuring devices and toys. Its dimensions are 11.6 mm wide and 5.4 mm high. A clear difference can be seen with all the others, also being one of the most sold and used. They have an autonomy of 145mAh.
They are batteries alkaline, so in addition to having a voltage of 1.5 volts They provide you with a 5-year storage guarantee. Surely you have had to use it on more than one occasion and you recognize it by its size. They are the only ones that are not lithium and have enormous popularity for their features and performance for what they are needed.
CR2430
these batteries lithium, which may also be known as DL2430 and BR2430, have a diameter of 24mm and a height of 30mm. They provide you with an autonomy of 285mAh. Therefore, they offer you good performance in flashlights, lamps, clocks, thermometers, calculators, remote controls and other devices. Its weight is around 4.5 grams.
They are the best-selling models for their good price and performance in its use, although perhaps not as well known as the previous ones for common users. They occupy high positions in sales and more and more users know about them. Its autonomy is 285mAh.
battery types
After having mentioned the best known, we are going to comment on all the ones that exist according to their composition, which are the alkaline, lithium, silver oxide and zinc-air. The voltage of all of them is different, with the lowest voltage being zinc air with 1.4 volts, followed by alkaline and silver oxide. Those with the highest tension are those with a lithium composition, such as those made of Manganese-Lithium Dioxide, Polycarbonate-Lithium Monofluoride and Polycarbonate-Lithium Monofluoride. If you think that the names are complex, keep reading to know a little more about them and what are their specific models.
Alkaline (LR)
The alkaline batteries are those that are made with this material and have a voltage of 1.5 volts. They are designed to be used even in extreme temperatures, they also last longer than others of different compositions and are very safe, although they must be disposed of carefully.
The LR54 (GP189, V10GA), LR44 (A76, 1166A, V13GA) and LR43(GP186, 1167A, V12GA) have the same diameter of 11.6mm. They differ in height, the first being 3mm, the second 5.4mm, and the third 4.2mm. The LR41 (L736, AG3, R736) are somewhat smaller with a diameter of 7.9mm and a height of 3.99mm). Of larger dimensions are the LR9 (PX625A, V625U) with 15.66 mm and 5.99 mm.
Lithium (CR and BR)
The lithium button batteries have a higher voltage than the previous ones, with 3 volts. They are perhaps the most used in some of their models because they are perfect for intermittent charging applications, a good range of temperatures and provide a Long useful life. They have two different compositions, the CR are Manganese-Lithium Dioxide and the BR are Polycarbonate-Lithium Monofluoride.
It’s good to know that the older your IEC code (its numbering) so is its diameter and height ratio. To give us an idea, the CR1025 have a diameter of 10 mm and a height of 2.5 mm. That is, the greater the number, the greater the dimension, although in equal dimensions the code differentiates the height of the stack. For example, the CR2025 and the CR2032 have the same diameter, only the former have a height of 2.5mm and 3.2mm.
The Models of lithium button that we can find are these: CR1025, CR1216, CR1220, BR/CR1225, CR1612, CR1616, CR1620, CR1632, CR2016, CR2025, BR/CR2032, CR2320, BR2325, BR/CR2330, CR2354, CR2430, CR2450 , CR2477 and CR3032.
Although they are not the most common, button batteries of Tionyl Lithium Tadiran (TL) are also used in electronics, for PCB assembly and in supply meters. Their voltage is 3.6 volts and they can last up to 10 years without wearing out.
Silver oxide (SR)
Silver oxide batteries have been made with this material and have good resistance to vibration and shaking. They provide good performance at low temperatures and are more resistant to discharge. Their voltage is 1.55 volts, so they discharge more quickly than the previous ones.
The Models of this type of battery are SR41, SR42, SR43, SR44, SR45, SR48, SR54, SR55, SR57, SR58, SR59, SR60, SR62, SR63, SR64, SR65, SR66, SR67, SR68 and SR69. It is important to note that all of them have alternative names, so you may find some that you do not recognize at first glance. All of them are differentiated according to their size, although this is not differentiated according to the numbering. They share the same 11.6mm dimensions as the SR42, SR43, SR44, SR54, SR55 models, although they differ in height. Each one of them is thought for certain specific needs.
Zinc Air Cell Batteries
Zinc air cell batteries are also known because they are the most used in hearing aids and because they have a good reaction speed. Due to their size, they have a plastic tab that allows them to be easily installed. They have a voltage of 1.4 volts.
There are 4 models to highlight, which are PR48 (7000ZD), PR41 (7002ZD), PR44 (7003ZD) and PR70 (7005ZD). The smallest are the PR70, with a diameter of 5.88mm and 3.6mm. The PR41 and PR48 have the same diameter of 7.9mm, but the former have a height of 3.6mm and the latter 5.4mm. The PR44 are the largest, with a diameter of 11.6mm and a height of 5.4mm.
