(1) No. 5 and No. 7 batteries are necessities in our daily life. So how do you define No. 5 and No. 7 batteries? When it comes to No. 5 and No. 7 batteries, it usually refers to cylindrical batteries. Therefore, from the perspective of battery size, the parameters of No. 5 and No. 7 batteries are diameter and height. According to IEC standards, R03 (No. 7 carbon battery) and LR03 (No. 7 alkaline battery) in primary battery have the same size, with a diameter of 10.5mm and a height of 44.5mm; The dimensions of R6p (No. 5 carbon battery) and LR6 (No. 5 alkaline battery) in the primary battery are the same, with a diameter of 14.5mm and a height of 50.5mm; The size of No. 5 battery and No. 7 battery can also be extended to rechargeable batteries; The most common is nickel metal hydride battery. Due to cadmium pollution, nickel cadmium batteries are rare in the market. Sometimes I hear about No. 5 lithium-ion battery, which is actually an analogy. The official name of the so-called No. 5 lithium-ion battery is 14500 lithium-ion battery.
(2) According to the naming method of lithium-ion battery, it refers to the lithium-ion battery with a diameter of 14.0mm and a height of 50.0mm. Check whether the size is basically consistent with the size of No. 5 battery specified in the primary battery? Another proof of this analogy is that I have never heard of No. 7 lithium-ion battery. Whether it is rechargeable battery or primary battery, although the overall dimensions of No. 5 battery and No. 7 battery are specified, their energies are absolutely different. Compared with primary battery, alkaline No. 5 battery and No. 7 battery are 4-5 times higher than carbon battery of the same model. Even for batteries of the same model, due to the different product formulations of battery manufacturers, the comparison of batteries of the same model from different manufacturers will also have obvious differences. Take the rechargeable battery. The capacity of NiMH No. 5 and No. 7 batteries can be twice that of similar nickel cadmium batteries.
(3) If 14500 lithium ion battery is also considered as No. 5 battery. Then, the total output power of the No. 5 lithium ion battery is more than twice that of the nickel metal hydride battery. In use, No. 5 and No. 7 rechargeable batteries can be used for high current discharge and are more durable than primary batteries. No. 5 battery and No. 7 battery are the most common battery models, which are closely related to people's daily life. In addition, No. 5 battery and No. 7 battery in rechargeable battery can also be used together, so that the application of No. 5 battery and No. 7 battery can be extended to a wider production and living field.
