The model name of the square battery: 6 numbers indicate the thickness, width and height of the battery, in millimeters. When any of the three dimensions is greater than or equal to 100mm, a slash should be added between the dimensions; if any of the three dimensions is less than 1mm, the letter t” shall be added in front of this dimension, and the unit of this dimension is one tenth of a millimeter.

ICP103450 represents a square secondary lithium battery pack. The cathode material is drilled. Its thickness is about 10mm, width is about 34mm, and height is about 50mm.

ICPO8/34/150 represents a square secondary lithium battery pack, the cathode material is diamond, its thickness is about 8mm, the width is about 34mm, and the height is about 150mm.

ICPt73448 represents a square secondary lithium ion battery. For the ion battery, the cathode material is a diamond, its thickness is about

0.7mm, the width is about 34mm, and the height is about 48mm.

The model name of the cylindrical lithium battery pack is composed of three letters And five digits, IEC61960 stipulates the rules for cylindrical and square batteries as follows:

Cylindrical lithium batteries, 3 letters followed by 5 numbers. 3 letters, I means there is a built-in lithium ion, L stands for lithium metal or lithium alloy electrode. The second letter stands for positive electrode material, C stands for diamond, N stands for nickel, M stands for manganese, and V stands for vanadium. The third letter stands for R stands for cylindrical shape.

There are 5 digits, the first 2 digits indicate the diameter, the last 3 digits indicate the height, and the unit is mm. For example: ICR18650 is a diameter of 18mm, a height of 65mm, and 0 means a round general-purpose 18650 cylinder Shaped battery.

3.6V is the indicator, and the voltage is 3.6V

C is the discharge rate of the battery when it is discharged, the unit is mAh, in layman’s terms it is the discharge size per unit time or Speed. For example, when the battery capacity used is discharged after 1h, it is called 1C discharge; when discharged after 5h, it is called 0.2C discharge.

The above is the interpretation of the meaning of the letters and numbers on the lithium battery. Everyone is helpful.


In today's world, have risen to an unexpected level of custom battery pack manufacturers. It has gained a lot of popularity and has come up with different kinds of variations in its content.
Review Shenzhen Chuangneng Ruiyuan Electronics CO.,LTD.'s progress at regular intervals, so we can continue with the strategies that work well and change or eliminate the ones that don't give the results we are looking for.
Choose the right platform for selling custom lithium ion battery and we'll reach the right customers. But if we have the right idea in the wrong platform, that still adds up to the wrong idea.
There have been conclusive evidence on 's role in custom battery pack manufacturers and custom battery pack manufacturers.
Shenzhen Chuangneng Ruiyuan Electronics CO.,LTD. clearly knows that people often launch something and love it and want to go on and on about it, but that's too normal and mediocre. There are lots of other competing products, so we need to keep it very, very unique.
