1. Internal materials
The essential difference between carbon batteries and alkaline batteries lies in the difference in internal materials. Carbon batteries are composed of carbon rods and zinc skins, but there are cadmium and mercury inside, which are not good for environmental protection, but they are cheap, so they still have a place in the market. Alkaline batteries do not contain heavy metal ions and have high current, which is good for environmental protection, is the direction of future battery development.

2. Performance
To put it simply, alkaline batteries and carbon batteries are that alkaline batteries are much more durable than carbon batteries, and carbon batteries have a much wider range of use than alkaline batteries. Carbon batteries have a small capacity and are suitable for smaller structures and principles. Current discharge can be used on clocks and remote controllers.

Alkaline batteries have a large capacity and are suitable for high-current discharge conditions, such as cameras. Of course, the time used on clocks and remote controls will be much more durable than carbon batteries.

3. Shelf life
Generally, the shelf life of alkaline batteries far exceeds the shelf life of carbon batteries. The shelf life of normal carbon batteries is one to two years. And now the shelf life of mainstream alkaline battery manufacturers has reached 5 years or even longer reached 10 years.
