Difference between alkaline battery, dry battery and carbon battery

Alkaline battery, also known as alkaline dry battery, alkaline zinc manganese battery and alkaline manganese battery, is the best variety in zinc manganese battery series. It is suitable for large discharge and long-term use. The internal resistance of the battery is low, so the current generated is greater than that of ordinary carbon batteries. Because these batteries do not contain mercury, they can be treated with domestic waste without deliberate recycling.

1、 Difference between alkaline battery and ordinary dry battery:

(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.

2、 Difference between alkaline battery and carbon battery:

1. Alkaline battery is 4-7 times of carbon battery, and the price is 1.5-2 times of carbon battery.

2. Carbon battery is suitable for low current electrical appliances, such as quartz clock, remote controller, etc; Alkaline batteries are suitable for high current electrical appliances, such as digital cameras, toys, razors, wireless mice, etc.

3. The full name of carbon battery should be carbon zinc battery (because its positive grade is generally carbon rod and its negative pole is zinc skin), also known as zinc manganese battery. It is the most common dry battery at present. It has the characteristics of low price and safe and reliable use. Based on the consideration of environmental protection factors, it still contains cadmium, so it must be recycled to avoid damage to the earth's environment. Alkaline battery is suitable for large discharge and long-term use. The internal resistance of the battery is low, so the current generated is larger than that of general zinc manganese battery. The conductive is copper bar and the shell is steel shell, which is safe and reliable without recycling, such as Changhong mercury free alkaline battery. Because of its environmental protection and high current, alkaline batteries are used more now.

4. About leakage: because the shell of carbon battery is a zinc cylinder as the negative electrode, it must participate in the chemical reaction of the battery, so it must leak over a long period of time, and it will leak in a few months with poor quality; The shell of alkaline battery is steel and does not participate in chemical reaction, so alkaline battery rarely leaks liquid, and the shelf life is more than 5 years.
