Button battery model comparison table and related knowledge introduction

Button batteries are widely used in daily life. Button batteries have excellent size and product advantages, and their service life is also very good. Therefore, they have won praise from users. But what do you know about button batteries? How to choose a suitable button battery model according to the actual situation? 1) Introduction to button batteries Button batteries, also called button batteries, refer to batteries with a size like a small button. Generally speaking, they have a larger diameter and thinner thickness (compared to cylindrical batteries such as AA batteries on the market); button batteries It is to divide the battery from the appearance to the same corresponding battery classification. There are cylindrical batteries, square batteries and special-shaped batteries; button batteries are generally rechargeable and non-rechargeable, including 3.6V rechargeable lithium-ion button batteries ( LIR series) 3V rechargeable lithium ion button batteries (ML or VL series); non-rechargeable include 3V lithium manganese button batteries (CR series) and 1.5V alkaline zinc manganese button batteries (LR and SR series); buttons The English letter in front of the battery model name indicates the type of battery. The number indicates the size. The first two digits indicate the diameter. The last two digits indicate the thickness; the button battery has a small diameter from 4.8mm to 30mm and thickness from 1.0mm to 7.7mm; generally Used as a backup power supply for various electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, memory cards, remote controls, electric toys, etc.; 2) Button battery model comparison table Silver oxide button battery is the most commonly used watch battery , The vast majority of watches use silver oxide button batteries. The voltage of a new battery is generally between 1.55V and 1.58V, and the battery's shelf life is 3 years. The running time is generally not less than two years when used on a well-functioning watch. Button lithium batteries, 3V lithium button batteries are mostly used in anti-theft devices, access control, computers, etc. Some watches are also equipped with lithium batteries. The shelf life of lithium batteries is 7 years. Under normal circumstances, users generally don't have to worry about battery expiration. The model of silver oxide button battery in Switzerland is 3##, and the model in Japan is usually SR###SW, or SR###W (# represents an Arabic numeral). The model of the button lithium battery is usually CR####. Button batteries of different materials have different models and specifications.

In detail, carbon button batteries are the most common and the cheapest. Alkaline batteries are a bit more expensive, but the discharge effect is good. Both voltages are 1.5V, ranging from alkaline AG1 to AG13, and the nominal capacity ranges from approximately 15mAh to 140mAh. Suitable for micro-amp discharge requirements. It is mostly used in calculators, electronic toys, hearing aids, lighters, watches, etc. Zinc-silver oxide button batteries can be regarded as the leader among button batteries. The voltage is 1.55V, the capacity is higher than that of carbon, the alkaline button battery, the high-order discharge curve is stable, about 90% of the part is always stable above 1.45V, the discharge curve is almost in a straight line, and then the power is turned off quickly, and the voltage drops vertically Go down. The main uses are: calculators, hearing aids, cameras, watches, etc. In particular, this kind of battery has a very good anti-leakage effect, and the long-term use effect is also good. I once replaced two domestic Dali AG13 batteries that were placed in the SLR camera to power the metering system. It took more than 8 years for the new product to be replaced, and there was no sign of leakage at all. It's really amazing! In addition to being powered by a single battery, button batteries have also developed high-voltage batteries due to their small size-that is, stacking multiple button batteries. Common typical models are: 6F22(9V)4F22(6V), 15F20( 22.5V), 10A(9V), 11A(6V), 23A(12V), 25A(9V), 26A(6V), 27A(12), 476A(6V), 120H7D(8.4V), 2X625A(3V), etc. Wait. Due to the use of button batteries, the combined battery pack is small and exquisite, but the discharge intensity is not large, and it is mostly used in small motors and DC power supplies for small radio transmission. It should be noted that because high-voltage stacked batteries are mostly produced by a combination of ordinary carbon batteries, they are generally not easy to store for a long time. When purchasing, you should pay attention to the production date and try to use products produced within one year. Button batteries usually contain harmful substances due to their low cost and are quite harmful to the environment. This type of battery needs to be recycled effectively by everyone and should not be thrown away at will. The knowledge introduced above is a comprehensive introduction to button batteries, including relatively professional button battery models and other purchase information that has attracted much attention. In the first part of the comparison of them, it is not difficult to find that there are many models that we can choose and trust. The specific reference content should be the purpose or brand, as well as the budget requirements. Therefore, in actual operation, you need to comprehensively refer to it. , To determine the appropriate one.
