The difference between alkaline batteries and ordinary dry batteries

There is a difference in weight: The same type of battery, alkaline battery is much heavier than ordinary dry batteries. For example, the weight of the No. 5 alkaline battery is about 24 grams, and the weight of the No. 5 ordinary dry battery is about 18 grams.

R represents a circular shape, and there is no letters in front of the letter. The previous labeled L is a alkaline battery. The two -digit number after R represents the size of the battery.
