CR2450 battery

Button lithium manganese dioxide battery

CR2450 button lithium manganese dioxide battery, named according to IEC standard. Among them, C- is a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode, and CR- indicates that the shape of the battery is a button type.

CR2450 battery, button battery CR2450;

2450 represents the standard size of the battery. The first two digits of the name of the button battery (one digit below 10mm) is the diameter, and the last two digits are the thickness. 24 in 2450 means the diameter is 24mm, 5 means the height of the battery is 5mm, and 0 means the shape of the battery is cylindrical

Rated voltage

The rated voltage is also called the nominal voltage. The battery voltage of the button lithium manganese battery is 3.0V, and the open circuit voltage is usually 3.1-3.3V.

  Working current

The working current refers to the current value that the battery can output when it is working; the rated current value of CR2450 is 0.2mA, which is mainly used for low-power electronic products. Generally, the battery can provide an output current of 0.001mA to 5mA, and the continuous output current can reach 15mA, the flash output current can reach 30mA, which can meet the requirements of most small electronic products such as light emission, sound generation, and RF output.

  Rated Capacity

Rated capacity refers to the current value that the battery outputs when working at rated time and rated power, usually in mAh or milliamp hours.

Under the IEC standard, the capacity of CR2450 is above 520mAh.


Is there any difference between cr2450e and cr2450?

  have. According to the relevant public information, the nominal voltage of the cr2450e and cr2450 batteries are both 3.0V, but the size and height are somewhat different. 24 in the cr2450 battery means the diameter is 24mm, and 50 means the height of the battery is 5.0mm. The primary battery is represented by CR plus four numbers, such as the model CR2450, C stands for lithium-manganese battery, R stands for cylindrical shape, 24 stands for diameter, and 50 stands for height.
