Alkaline battery is a kind of long-life disposable battery. Its shape and size are the same as ordinary manganese batteries. Because of its improved performance, it is often used as a flash power source. What is the difference between alkaline manganese batteries and ordinary batteries?


1. Different logos
The Alkaline battery catalog takes cylindrical batteries as an example. The category identification of alkaline battery is LR, such as "LR6" is AA size alkaline battery, and "LR03" is AAA alkaline battery; the category of ordinary dry battery is identified as R, such as "R6P" is high-power AA size ordinary battery, "R03C "It is a high-capacity AAA battery. In addition, the alkaline battery logo has a unique "ALKALINE" content.

2. The difference in shape

Alkaline battery can touch the annular groove at the end close to the anode. Generally, the cylindrical surface of the ordinary dry battery does not have any groove. This is due to the different sealing methods of the two.

3. There is a difference in weight

With the same type of battery, alkaline battery is much heavier than ordinary dry battery. For example, the weight of the AA size alkaline battery is about 24 grams, and the weight of the AA size ordinary dry battery is about 18 grams.

R stands for round shape, and when there is no letter in front, it means normal battery. The L marked on the front means it is Alkaline battery. The two digits after the R indicate the size and model of the battery. For example, 03 represents the AAA size battery, and the last letter indicates the performance of the battery, S-normal type, P-high power type, C-high capacity type. Some ordinary batteries are marked with S, and some do not.

The ordinary dry batteries we use in our daily life include alkaline manganese batteries and ordinary dry batteries. The former has high capacity and relatively durable batteries, but the price is much higher than that of ordinary dry batteries. Therefore, many small vendors take advantage of consumers' ignorance and sell ordinary dry batteries to us as alkaline manganese batteries. Everyone should be more vigilant about this.
