button battery cr1620

What are the button battery cr1620 labels?

According to IEC standards, the label of nickel-metal hydride batteries consists of 5 parts.

01) button battery cr1620 type: HF and HR represent nickel-metal hydride batteries

02) button battery cr1620 size information: including the diameter and height of round batteries, the height, width and thickness of square batteries, and the values are separated by slashes, unit: mm

03) Discharge characteristic symbol: L indicates that the suitable discharge current rate is within 0.5C

M indicates that the suitable discharge current rate is within 0.5-3.5C

H indicates that the suitable discharge current rate is within 3.5-7.0C

X indicates that the button battery cr1620 can work at a high discharge current of 7C-15C

04) High temperature button battery cr1620 symbol: represented by T

05) button battery cr1620 connector: CF represents no connector, HH represents the connector for button battery cr1620 pull-type series connector, and Hb represents the connector for button battery cr1620 strip parallel series connection.

For example: HF18/07/49 indicates a square nickel-metal hydride button battery cr1620, with a width of 18mm, a thickness of 7mm, and a height of 49mm.

KRMT33/62HH indicates a nickel-cadmium button battery cr1620, with a discharge rate between 0.5C-3.5, a high-temperature series single cell (without connector), a diameter of 33mm, and a height of 62mm.

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

01) button battery cr1620 identification composition: 3 letters, followed by 5 numbers (cylindrical) or 6 (square) numbers.

02) The first letter: indicates the negative electrode material of the button battery cr1620. I—indicates lithium ion with built-in button battery cr1620; L—indicates lithium metal electrode or lithium alloy electrode.

03) The second letter: indicates the positive electrode material of the button battery cr1620. C—cobalt-based electrode; N—nickel-based electrode; M—manganese-based electrode; V—vanadium-based electrode.

04) The third letter: indicates the shape of the button battery cr1620. R—indicates cylindrical button battery cr1620; L—indicates square button battery cr1620.

05) Numbers: Cylindrical button battery cr1620: 5 numbers represent the diameter and height of the button battery cr1620 respectively. The unit of diameter is millimeter, and the unit of height is one tenth of millimeter. When any dimension of diameter or height is greater than or equal to 100mm, a slash should be added between the two dimensions.

Square button battery cr1620: 6 numbers represent the thickness, width and height of the button battery cr1620 respectively, 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, add the letter "t" before this dimension, and the unit of this dimension is one tenth of millimeter.

For example: ICR18650 represents a cylindrical secondary lithium-ion button battery cr1620, the positive electrode material is cobalt, its diameter is about 18mm, and its height is about 65mm.

ICR20/1050.

ICP083448 represents a square secondary lithium-ion button battery cr1620, the positive electrode material is cobalt, its thickness is about 8mm, its width is about 34mm, and its height is about 48mm.

ICP08/34/150 indicates a square secondary lithium-ion button battery cr1620, the positive electrode material is cobalt, its thickness is about 8mm, its width is about 34mm, and its height is about 150mm.

ICPT73448 indicates a square secondary lithium-ion button battery cr1620, the positive electrode material is cobalt, its thickness is about 0.7mm, its width is about 34mm, and its height is about 48mm.
