Whether it is a common air-conditioning remote control in life, TV remote control or children's toys, wireless mouse keyboard, quartz clock electronic watch, radio can not do without batteries. When we go to the store to buy a battery, we usually ask whether it is cheaper or more expensive, but few people ask whether we use alkaline batteries or carbon batteries.
Today we take a brief look at these two different batteries.
Carbon batteries are also called dry batteries, which is relative to batteries with flowable electrolytes. Carbon batteries are suitable for flashlights, semiconductor radios, tape recorders, electronic clocks, toys, etc., and are mainly used for low-power appliances, such as watches and clocks, wireless mice, etc. Large-power appliances should use alkaline batteries, such as cameras, some camera alkalis If sex is unsustainable, then you need to use NiMH. Carbon batteries are the most widely used batteries in our lives. The earliest battery we have come in contact with should be the one with the lowest price and wide range of uses.
The full name of the carbon battery should be carbon zinc battery (because it is generally a positive electrode is a carbon rod, the negative electrode is a zinc skin), also known as zinc manganese battery, is the most common dry battery, it has the characteristics of low price and safe and reliable use, based on Considering environmental protection factors, because it still contains cadmium, it must be recycled to avoid damage to the global environment.
The advantages of carbon batteries are obvious. Carbon batteries are easy to use and cheap, and there are many types and prices to choose from. The natural shortcomings are also obvious. For example, it can not be recycled. Although the cost of one-time input is very low, the cumulative use cost is worth paying attention to, and this battery contains harmful substances such as mercury and cadmium that cause damage to the environment.
The alkaline battery adopts the opposite electrode structure of the ordinary battery in structure, which increases the relative area between the positive and negative electrodes, and the potassium hydroxide solution with high conductivity replaces the ammonium chloride and zinc chloride solution. The flake shape is changed into granular shape, which increases the reaction area of the negative electrode, and the high-performance electrolytic manganese powder is used, so the electrical performance can be greatly improved.
In general, the alkaline batteries of the same type are 3-7 times the power of ordinary carbon batteries, and the gap between the low temperature performance is greater. Alkaline batteries are more suitable for high-current continuous discharge and electrical applications requiring high working voltage , Especially suitable for camera, flash, razor, electric toys, CD player, high-power remote control, wireless mouse, keyboard, etc.
On the alkaline battery identification, you can see whether the word ALKALINE or the word "alkaline battery" is printed in Chinese.
How to distinguish between these two different batteries?
1. Look at the product logo
For the batteries we usually use, the category label of alkaline batteries is LR, such as "LR6" is the No. 5 alkaline battery, and "LR03" is the No. 7 alkaline battery; the category label of ordinary dry batteries is R, such as "R6P" It is a high-power type No. 5 ordinary battery, and "R03C" is a high-capacity type No. 7 ordinary battery. In addition, alkaline batteries will be marked with "ALKALINE".
2. Different weight
The same type of batteries, alkaline batteries are generally heavier than ordinary dry batteries.
3. Touch by hand
Due to the different packaging methods of the two, the alkaline battery can touch a ring-shaped slot on the end near the negative electrode, but the ordinary carbon battery does not
What should I pay attention to in daily use?
Although alkaline batteries have many advantages, they have a long service life and sufficient power. But in daily use, be sure to use it according to the instructions
For example, our commonly used quartz electronic watches are not suitable for alkaline batteries. For the watch, the movement of the watch only needs a small current to cope with it. Using alkaline batteries or rechargeable batteries will cause damage to the movement, cause inaccurate travel time, and even burn the movement, affecting the service life.
Carbon batteries are mainly used in low-power electrical appliances, such as watches and remote controllers, etc., but the larger power consumption should use alkaline batteries, such as cameras, children's toy car remote control car, like some cameras need more Big NiMH battery.
Therefore, when choosing the battery, be sure to choose it correctly according to the manual.
