Button battery Dimensions like a small button Features Large diameter, thinner thickness Application range Various types of electronic products, the backup power supply 1 Basic meaning 2 Application 3 Classification Oxide Alkaline manganese Lithium ion hammer hammer Welding pin battery 4 Common model 5 Key effects 6 Precautions Button battery basic meaning Edit button batteries Commonly used are two types of rechargeable and non-rechargeable battery models, including 3.6V rechargeable lithium ion battery (1) (LIR series) , Button Cell 3V rechargeable lithium ion battery (ML or VL series); not charge, including 3V lithium manganese button cell (CR series) and 1.5V alkaline zinc manganese button cell (LR and SR series); more common Button batteries are used for toys and gifts on the AG3, AG10, AG13 battery, computer motherboard battery, model CR2032 for the electronic dictionary inside the CR2025, Button Cell for the top of the electronic watch CR2016 or SR44, SR626, etc .; button battery (9V), 4F22 (6V), 15F20 (22.5V), the first two digits indicate the thickness of the battery, the first two digits indicate the thickness; the typical 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)
Nippon batteries are made of chemical composition such as carbon, alkaline, zinc-silver oxide, zinc-air, lithium-manganese dioxide, nickel-cadmium rechargeable button batteries, Button Cell nickel-metal hydride rechargeable batteries and so on. If the shape of the monomer and the layers of the distinction. In particular, the carbon button battery is the most common, but also the cheapest, alkaline little expensive, but the discharge effect is good. Both of these voltages are 1.5V, ranging from alkaline AG1 to AG13, with nominal capacities ranging from about 15mAh to 140mAh. Suitable for micro-level discharge requirements. Used in calculators, electronic toys, hearing aids, lighters, Button Cell watches and so on. In addition to the battery can be a single battery, due to its small size, but also the development of high-volt battery - will be more than one button battery stack, common typical models are: 6F22 (9V), F22 (6V), 15F20 (22.5V) (9V), 11A (6V), 23A (12V), 25A (9V), 26A (6V), 27A (12), 476A (6V), 120H7D (8.4V), 2X625A (3V), and the like.
As a result of the use of button batteries, the combination of the battery is very small, but the discharge intensity is not large, used in small motors, small radio with DC power supply. It should be noted that because the high-stack stack batteries are mostly ordinary carbon battery combination production, Button Cell generally not easy to long-term storage, should pay attention to the date of purchase, as far as possible the use of products produced within a year. Button batteries because of low cost, usually contain harmful substances, the environment is very dangerous, this battery needs more effective recovery, do not arbitrarily discarded.
Zinc - silver oxide button batteries, be regarded as a leader in the battery. Voltage 1.55V, the capacity is higher than the carbon, alkaline button batteries, high-order discharge curve is smooth, about 90% of the part is always stable at 1.45V or more, Button Cell the discharge curve is almost a straight line, and then quickly power down, the voltage vertical Go on. The main uses are: calculator, hearing aids, cameras, watches and so on. In particular, that the battery leakage effect is particularly good, and long-term use effect is also good.
Nickel-cadmium (Ni-Cd), Ni-MH (Ni-MH) secondary charging button batteries are usually combined into a battery pack, the use of single battery power supply is relatively small. Single cell battery style is more uniform, the general common nickel-metal hydride nickel-cadmium button battery models are almost that several (except for military products). Combination of more styles. Button Cell China's domestic standard to the button battery code known as GNB is "cadmium nickel flat" the first letter of the combination of Chinese alphabet; GNB in front of the number of single-cell number, GNB behind the figures on behalf of the capacity. To give you an example, 10GNB03 (a force-specific artillery laser rangefinder battery), is a 10 by the GNB0.3Ah button battery combination of appearance and D-type (No. 1) battery exactly the same battery. In the list of several practical examples of common examples, there are old models of home cordless phone there is a considerable part of the button battery pack, the configuration of the 3.6V or 4.8V button battery pack, Button Cell the single battery is mostly 280K / H; Hand-held small riot flashlight (that is, can be self-defense self-defense with the kind of self), inside the battery is mostly 4.8V button battery pack, most of the 280K / H combination; IPC above the backup memory (also known as CMOS) using the 3.6V button battery pack, the majority of 60K / H combination. Need to point out that the monomer nickel cadmium, nickel-metal hydride button batteries can be bought, some people like their own combination of processing battery pack, the combination of electric iron, which is very inappropriate.
Let me talk about the battery batteries in the lithium battery, lithium - manganese dioxide one-time button batteries (CR button battery series).
Lithium manganese one-time button battery nominal voltage is 3V, the termination voltage of 2V, the typical operating current in 0.1-0.2mA. It uses a very stable chemical properties of manganese dioxide as a cathode material, with a very high energy than the lithium metal anode material. Button Cell The average annual capacity reduction is not greater than 2%, long storage life. The battery is semi-sealed and is safe to use. Lithium manganese one-time button battery temperature to adapt to the larger range of -20 to +60 degrees Celsius under the conditions can work properly. Use more in electronic dictionaries, motherboard CMOS batteries, watches and so on.
