Common button batteries are made of chemical composition such as carbon, alkaline, zinc-silver oxide, zinc-air, lithium-manganese dioxide, nickel-cadmium rechargeable button batteries, 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, Button Cell 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.
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, 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 of the effect is also good, I have to replace the customer on the SLR camera inside the metering system for the supply of domestic Dali AG13 battery, Button Cell More than eight years before the replacement of new products, and there are no signs of missing the night.
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, 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, Button Cell this battery needs more effective recovery, do not arbitrarily discarded.
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 style is more uniform.
Common common nickel-metal hydride nickel-cadmium button battery models are almost that several (except for military products). Combination of more styles. 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, the single battery is mostly 280K / H; Hand-held small riot flashlight (that is, Button Cell 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, Button Cell which is very inappropriate.
