What is the difference between alkaline battery and ordinary battery

The ordinary dry batteries we use daily include alkaline batteries and ordinary dry batteries. The former has high capacity and relatively durable batteries, but the price is much higher than ordinary dry batteries. Here are some differences between alkaline dry batteries and ordinary dry batteries. I hope it will be useful to you.

1. Different identification: take cylindrical battery as an example. The category identification of alkaline battery is LR, such as "LR6" is No. 5 alkaline battery and "LR03" is No. 7 alkaline battery; The category identification of ordinary dry battery is r, such as "R6p" is high-power No. 5 ordinary battery and "r03c" is high-capacity No. 7 ordinary battery. In addition, there is a unique "alkaline" content in the logo of alkaline battery.

2. Difference in shape: the alkaline battery can touch the annular groove at the end close to the negative electrode. Generally, there is no groove on the cylindrical surface of the ordinary dry battery, which is formed due to the different sealing methods between the two.

3. There are differences in weight: alkaline batteries of the same model are much heavier than ordinary dry batteries. For example, the weight of No. 5 alkaline battery is about 24 grams, and the weight of No. 5 ordinary dry battery is about 18 grams.

4. R stands for a circle. If there is no letter in front of it, it means an ordinary battery. L in front indicates alkaline battery. The two digits after r represent the size and model of the battery. For example, 03 represents No. 7 battery, and the last letter represents the performance of the battery. S-ordinary type, p-high-power type and c-high-capacity type. Some ordinary batteries are marked with s and some do not.
