1. Different uses

Carbon batteries are generally used in devices that require less current. Carbon batteries are very suitable for flashlights, transistor radio, tape recorders, cameras, electronic clocks, electronic toys, scientific research, telecommunications, navigation, aviation, medicine and many other fields in the national economy.

alkaline batteries are suitable for daily necessities such as flashlights, razors, electric toys, CD players, high-power remote controllers, wireless mice and keyboards.

second, the amount of electricity is different

from the most basic point of view, alkaline batteries have higher cost performance than carbon batteries.

the capacity of alkaline battery will decrease due to the increase of output current.

for example, the same battery can have a capacity of 3mAh at low output current, but when it is used at negative load of 1A current, the capacity is only 7mAh, which is less than 1/4 of the original capacity.

Third, the degree of environmental protection is different

There is another name for alkaline batteries: alkaline dry batteries or alkaline zinc-manganese dry batteries. The internal resistance of alkaline batteries is lower than that of carbon batteries, while the mercury content of environmentally friendly alkaline batteries is only .25%, so it is not necessary to recycle them. Therefore, alkaline batteries are much more environmentally friendly than carbon batteries.
