tell the difference between alkaline batteries and carbon batteries? Come in and learn!
Alkaline batteries and carbon batteries are two of the more common batteries on the market today. They are both dry batteries, but the materials used to produce these two batteries are different, giving them different characteristics.
As the main types of dry batteries, they can both provide energy sources for some electronic products, but there are obvious differences between the two. Today, alkaline batteries are more mainstream than carbon batteries and have a wider range of applications.
Let’s talk about carbon batteries first. Carbon batteries are our first-generation disposable batteries. They have a relatively fixed capacity and low discharge current, and are suitable for use in equipment with ultra-low current discharge. The advantages of carbon batteries are that they are relatively low-priced and relatively safe. Before the birth of alkaline batteries, they were once popular in my country. However, this kind of battery contains some heavy metals that are harmful to the natural environment. If it is discarded casually, it will cause harm to the environment. Pollution, so this kind of battery must be recycled after use.
Let’s look at alkaline batteries. Alkaline batteries are quite common batteries nowadays. Compared with carbon-based batteries, alkaline batteries have higher capacity, sufficient current, and relatively stable voltage, so they are highly popular in the market. Alkaline batteries are suitable for electronic instruments and products that require stable discharge and long discharge time. Moreover, the internal resistance of this kind of battery is relatively low, and the current it generates is larger than that of ordinary carbon batteries. Alkaline batteries also have good environmental protection, which is also the difference between them and carbon batteries. For example, the alkaline batteries produced by SUNMOL, DG SUNMO ALKLAINE BATTERY , are mercury-free and cadmium-free. They will not cause harm to the environment after being discarded in nature. There is no need for professional recycling after use.
From the perspective of battery composition, the full name of carbon battery is carbon-zinc battery, which is composed of carbon rods and zinc skin; while alkaline batteries usually use highly conductive potassium hydroxide solution as the main component, and the internal resistance of the battery is low, so it produces The current is larger than that of ordinary carbon batteries.
In terms of shelf life, carbon batteries generally have a shelf life of one to two years; while alkaline batteries have a longer shelf life, such as DG SUNMO alkaline batteries, which have a long-lasting energy concentration of 10 years, so you can store them safely if you buy more.
