It is important to purchase a carbon battery and alkaline battery, regardless of the supermarket or small grocery store, regardless of the supermarket or small grocery store. So, where the two batteries are different, how do you choose the battery correctly? Below we study these two batteries, respectively. The difference between the two batteries is as follows: First, the carbon battery and the alkaline battery are dry batteries, just two categories that are divided according to the different plants.

Second, the full name of the carbon battery should be a carbon-zinc battery (because it is generally the carbon stick, the negative electrode is zinc skin), also known as zinc manganese battery, is the most common dry battery, it has a safe use of safety and safety Reliable characteristics, since the carbon battery contains heavy metal cadmium, it must be recovered to avoid damage to the earth environment. (So ​​the level of us usually used is a carbon stick, the negative is zinc-skin battery to be recovered). Third, alkaline batteries are also known as alkaline dry batteries or basic zinc manganese dry batteries, suitable for instruments that need to be discharged from large and long-term, and the alkaline battery is low, and therefore there is a large zinc manganese battery.

And environmentally friendly alkaline batteries contain only 0.025%, no need to recover. Based on the environmental protection and current of alkaline batteries, more basic batteries are used in alkaline batteries.

(Nanfu is alkaline battery) Fourth, the nominal voltage of the carbon battery and alkaline battery is 1.5V, but the same volume of alkaline battery capacity is more capacity, which is more adapt to large current discharge. Fifth, the essential difference between carbon-based batteries and alkaline batteries is the different internal materials.

In summary, the carbon battery consists of a carbon rod and zinc skin, but there is cadmium and mercury, which is not conducive to environmental protection, but it is cheap, so there is still a place in the market, and alkaline batteries do not contain heavy metal ions, current, It is good to be environmentally friendly, it is the direction of future battery development! Sixth, alkaline batteries are 4-5 times that of carbon-based battery, and the price is 1.5-2 times of carbon battery. Carbon batteries are suitable for electrical appliances such as quartz clocks, remote controls, radios, etc.

, such as quartz clocks, remote controls, radios; alkaline batteries, such as electric shaver, wireless microphone, electric toothbrush, electric toys, handheld computers, etc. Performance is more alkaline batteries and carbon-based batteries, that is, alkaline batteries are much durable than carbon-based batteries, while carbon-based batteries are cheaper than alkaline batteries. The carbon-based battery capacity is small, from the structure and principle, suitable small current discharge, watch, and remote control can be used.
