What is the specific explanation for alkaline batteries?

In terms of environmental protection. Alkaline batteries are also called alkaline dry batteries or alkaline zinc-manganese dry batteries. They are suitable for instruments that require large discharge and long-term use. Alkaline batteries have low internal resistance, so the current generated is larger than that of ordinary zinc-manganese batteries, which is environmentally 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 offered.
For example, Nanfu, as the light of domestic products, is an alkaline battery that is very prominent in terms of power storage and use time. It is also called alkaline dry battery or alkaline zinc manganese dry battery. It is suitable for instruments that require large discharge and long-term use. Alkaline batteries have low internal resistance, so the current generated is larger than that of ordinary zinc-manganese batteries, while environmentally friendly alkaline batteries contain only 0.025% of 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 offered.
Alkaline batteries are heavier than carbon batteries. For example, AA alkaline batteries weigh about 23 grams each, while AA batteries weigh about 15 grams each. Second, there will be a ring of grooves on the negative end of the alkaline battery by touching it with your finger or scratching it with your nails, while there is no groove here for the carbon battery. Commonly used No. 5 and No. 7 alkaline batteries are marked with LR6 and LR03 respectively, while No. 5 and No. 7 carbon batteries are marked with R6 and R03 without "L". Alkaline batteries are heavier than carbon batteries.
