1. Check the battery model online according to the mobile phone model.
2. If it is a used battery, peel off the outer packaging. The battery model and manufacturer code are written inside, and you can also measure the size yourself, if you have not contacted. with bare cells, you may not understand that it is a battery. Please refer to the naming method, hope it can help you:
1. The battery identification is made up of 3 letters followed by 5 cylindrical or 6 square numbers.
2. The first letter indicates the material of the negative electrode of the battery. I indicates lithium-ion with integrated battery. L indicates lithium metal electrode or lithium alloy electrode.
3. The second letter represents the material of the positive electrode of the battery C. Cobalt-based electrode N. Nickel-based electrode M. Elmanganese-based electrode V. Vanadium-based electrode.
4. The third letter indicates the shape of the battery. R indicates a cylindrical battery and L indicates a square battery. ?
For example:
ICP083448 indicates that the cathode material of a square secondary lithium-ion battery is cobalt, with a thickness of about 8mm, width approximately 34 mm and a height of approximately 48 mm. ?
Analyze the battery model according to the battery size, subtract 5mm from the height (protection board), and keep other items unchanged.
