IEC regulations on the marking of rechargeable batteries [Copy link]

According to the IEC standard, the label of Ni-Cd Ni-MH batteries consists of 5 parts

1. Battery type KR indicates nickel-cadmium battery, HF indicates nickel-metal hydride battery, and HR indicates nickel-metal hydride battery.
2. Battery size information includes the diameter and height of round batteries, the height, width and thickness of square batteries, and the values are separated by slashes in mm.
3. Discharge characteristic symbols L indicates that the appropriate discharge current rate is within 0.5C,
M indicates that the appropriate discharge current rate is within 0.5-3.5C,
H indicates that the appropriate discharge current rate is within 3.5-7.0C, and
X indicates that the battery can operate at a high discharge current rate of 7C-15C.
4. The symbol for high-temperature batteries is T.
5. Battery connectors CF indicates no connectors, HH indicates connectors for battery pull-type series connection, and HB indicates connectors for battery strips connected in parallel in series.
For example, HF18/07/49 indicates a square nickel-metal hydride battery with a width of 18mm, a thickness of 7mm and a height of 49mm.
KRMT33/62HH indicates that the discharge rate of nickel-cadmium batteries is between 0.5C-3.5, and the high-temperature series single battery has no connectors with a diameter of 33mm and a height of 62mm.

According to the IEC61960 standard, the identification of secondary lithium batteries is as follows:

1. The battery identification consists of 3 letters followed by 5 numbers (cylindrical or 6 square numbers)
. 2. The first letter indicates the negative electrode material of the battery. I indicates lithium ion with built-in battery. L indicates lithium metal electrode or lithium alloy electrode.
3. The second letter indicates the positive electrode material of the battery. C is a cobalt-based electrode. N is a nickel-based electrode. M is a manganese-based electrode. V is a vanadium-based electrode.
4. The third letter indicates the shape of the battery. R indicates a cylindrical battery. L indicates a square battery.
5. The 5 numbers for a cylindrical battery indicate the diameter and height of the battery respectively. The unit of diameter is millimeter and the unit of
height is one-tenth of a millimeter. When either the diameter or height is greater than or equal to 100 mm, a slash should be added between the two dimensions.

The six numbers of a square battery represent the thickness, width and height of the battery in millimeters. If 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, add the letter t in front of the dimension. The unit of this dimension is one tenth of a millimeter.

For example:

ICR18650 means that the positive electrode material of a cylindrical secondary lithium-ion battery is cobalt, and its diameter is about 18mm and its height is about 65mm.
ICR20/1050
ICP083448 means that the positive electrode material of a square secondary lithium-ion battery is cobalt, and its thickness is about 8mm, width is about 34mm and height is about 48mm.
ICP08/34/150 means that the positive electrode material of a square secondary lithium-ion battery is cobalt, and its thickness is about 8mm, width is about 34mm and height is about 150mm. ICPt73448 means that the positive electrode material of a square secondary lithium
-ion battery is cobalt, and its thickness is about 0.7mm, width is about 34mm and height is about 48mm
