What is carbon batteries? When consumers buy batteries how to distinguish it?

When consumers buy batteries, often for the same type of battery and be suspicious of the price disparity. Solve this problem need to distinguish between the battery category, if you want cheap, carbon-zinc batteries may be your goal. So, what is carbon batteries do? What are its characteristics? Why look for cheaper battery carbon battery and not the other? It must proceed from the principle of talking about carbon batteries.
Stands for carbon batteries zinc - manganese dioxide batteries, a chemical power of the original battery is disposable batteries. From this basic classification, we can see what is the basic characteristics of carbon-zinc batteries. Firstly, the properties of carbon batteries comes from its electrolyte nature. What is a carbon battery electrolyte characteristics? Because the battery electrolyte is a carbon paste does not flow, it is attributable to the battery. Second, what is the one-time carbon battery characteristics? That is to say, carbon batteries discharge chemical reaction is irreversible, a full completion of the reaction, the battery power consumption also finished, non-rechargeable reuse.
Understanding of the properties of the carbon batteries, let's look at what is the structural characteristics of carbon-zinc batteries. All batteries are made of carbon cathode material, electrolyte and cathode materials, carbon battery from the middle part is a part of graphite and manganese dioxide carbon rod, covered NH4CL, ZnCL2 and starch paste, the shell is made of zinc tube structure, zinc is also negative.
Carbon battery is discharging process work. What is a carbon battery discharge mechanism? Carbon battery through the positive and negative reactions, the chemical energy into electrical energy supplied to the external circuit. In this reaction, the zinc is oxidized loses electrons, the electron is reduced manganese. With this reaction process is the voltage drop. Carbon battery is full-load voltage up to 1.6V near the nominal voltage or working voltage of 1.5V, 0.9V when the voltage drops appearing in court, it means power is exhausted, 0.9V carbon battery so called termination voltage.
Carbon batteries from the structure and scale can be classified. What are the criteria for classification carbon batteries? From a structural point of view, carbon-zinc batteries are divided into two kinds of paste-type and paperboard, cardboard type currently on the market are seen carbon batteries. From the model point of view, on the 5th battery, on the 7th battery is the most common, as well as the 1st, the 2nd, etc. used in some special places, in addition to their shape is not the same, the difference also with the volume of electricity enlarge.
Carbon batteries used in watches and other low-power appliances, its maintenance and use has its own characteristics, so look at what is carbon battery precautions necessary: ​​one, because this is a non-rechargeable batteries, so forced charging will cause leakage or risk of damage to the equipment. Second, the battery is in use, avoid mixed mix battery "+, -" pole should be in accordance with the required direction using the equipment properly installed to prohibit short-circuit, heat, burn, and open the battery. Third, the battery and clean when not in use and long-term safe storage and electrical appliances when not separated; addition, the used carbon batteries do not carelessly throw away, because some of the carbon-zinc batteries are not environmentally friendly, so for carbon Battery Our biggest concern is to recycle fixed to reduce the air pollution of the environment and so on.
