The difference between R6 carbon battery and alkaline battery
First, R6 carbon batteries and alkaline batteries are both dry batteries, but they are divided into two categories according to different materials.
Second, the full name of the R6 carbon battery battery should be a carbon-zinc battery (because it is generally a carbon rod for the positive pole and a zinc skin for the negative pole), also known as a zinc-manganese battery. It is the most common dry battery at present. It has low price and The use of safe and reliable features, because the R6 carbon battery contains heavy metal cadmium, it must be recycled to avoid damage to the earth's environment. (So we usually use carbon rods as the positive pole and zinc-skinned batteries as the negative pole to be recycled).
Third, alkaline batteries are also called alkaline dry batteries or alkaline zinc-manganese dry batteries. They are suitable for instruments that require large discharge capacity and long-term use. The internal resistance of alkaline batteries is low, so the current generated is larger than that of ordinary zinc-manganese batteries. , while the environment-friendly alkaline batteries contain only 0.025% mercury and do not need to be recycled. Based on the environmental protection and high current characteristics of alkaline batteries, more alkaline batteries are now mentioned.
Fourth, the nominal voltage of R6 carbon battery and alkaline battery is 1.5V, but the capacity of alkaline battery of the same volume is larger, and it is more suitable for large current discharge.
Fifth, the essential difference between carbon batteries and alkaline batteries lies in the difference in internal materials. In short, the R6 carbon battery battery is composed of carbon rods and zinc skin, but there are cadmium and mercury inside, which is not conducive to environmental protection, but it is cheap, so it still has a place in the market, and alkaline batteries do not contain heavy metal ions, current Large, beneficial to environmental protection, is the direction of future battery development!
Sixth, alkaline batteries are 4-5 times the power of R6 carbon batteries, and the price is 1.5-2 times that of R6 carbon batteries. R6 carbon batteries are suitable for low-current electrical appliances, such as quartz clocks, remote controls, radios, etc.; alkaline batteries are suitable for high-current electrical appliances, such as BP players, CD players, electric toothbrushes, electric toys, handheld computers, etc. .
