How to distinguish different types of button batteries

In view of this situation, our salesmen must be familiar with the model and capacity of button batteries, and it is necessary to keep them in mind. With so many types, models and capacities of button batteries, how can we distinguish them?

Taking lithium manganese button batteries as the category, first summarize and classify the battery models:

(The production models of each manufacturer are different, and the following only provide universal representation, taking Liyuan Battery Technology as an example.)

1、 Disposable button battery series:

①The diameter is 20mm and the height is different, mainly including CR2016, CR2020, CR2025, CR2032, CR2050, etc.

②The diameter is 16mm and the height is different, mainly including CR1616, CR1620, CR1625, CR1632, etc.

③The diameter is 24mm and the height is different, mainly including CR2430, CR2450, CR2477, etc.

④The diameter is 23mm and the height is different, mainly including CR2350, CR2354, etc.

⑤The diameter is 12mm and the height is different, mainly including CR1212, CR1216, CR1220, CR1225, etc.

⑥Models with diameters of 10mm and 9mm are widely used in secondary batteries, such as CR1025 and CR943.

To sum up, we can classify the above ① and ②. The diameters are 16mm and 20mm, and the heights are mainly 16mm, 20mm, 25mm and 32mm, respectively. One CR2050 model can be added to the diameter of 20mm; Secondly, classify ③ ④, remember the heights of 30, 50 and 77 when the diameter is 24mm, and remember the heights of 50 and 54 when the diameter is 23mm; Finally, ⑤ ⑥ is classified as a small type battery. The height of 12mm in diameter is mainly 16, 20 and 25mm. In addition, a 12 digit with the same diameter is added as the height, namely CR1212.

2、 The wide temperature button battery uses carbon fluoride as the cathode material on the basis of the primary battery, and the temperature range has been expanded. The primary battery model is indicated by adding "HT", such as CR2450HT. In foreign countries, "BR" is directly added to the battery model, namely BR2450. Therefore, remembering the primary battery model also means remembering the wide temperature battery model.

3、 The secondary battery has a series different from the primary battery. It has the same height and different diameters, such as LIR943, LIR1043, LIR1243, etc., as well as LIR1254, LIR1454, LIR1654, etc. These models are widely used in TWS earphones. LIR1043 and LIR1254 power sources currently produce high-capacity products, and LIR1254 can be quickly charged. In addition, there are ordinary series: LIR2477, LIR2450, LIR2032, LIR2025, LIR2016, LIR1632, LIR1620, LIR1220, etc.

Remember that these varieties and models are classified either by the same diameter, or by the same height, or from the largest to the smallest, or from the smallest to the largest. In a word, summarize them in one way before memorizing.
