Jauch Lithium Coin Cell and Manganese Dioxide Batteries – Technical Summary

Lithium batteries come in a variety of versions which contrast in terms of separator, electrolyte and cathode. Considering they are applicable to a broad spectrum of applications and industries, they come indifferent designs and sizes. As the result of their high voltage (3 volts),high temperature range, high capacity and long-life cycle due to low discharge,they are one of the most commonly used batteries across numerous industries.

Most commonly, Jauch’s lithium coin cell batteries can be found in watches, toys, car keys, digital weight scales, medical equipment and tools, as well as memory any type of memory back up.

On the technical side, lithium is an ideal negative electrode material. As such, it has the highest possible voltage. Therefore,this type, lithium manganese dioxide batteries (LiMnO2), of batteries are used across so many applications including electronic components and battery back-up for motherboards.

Below, we will discuss the technical capabilities of the commonly used Jauch batteries.

CR2032

Lithium button and coin cell batteries, such as the CR2032, are used to power small portable electronics devices such as wrist watches,pocket calculators, artificial cardiac pacemakers, implantable cardiac defibrillators, automobile key less entry transmitters, and hearing aids.Button and coin cell batteries are typically 5-25 millimeters in diameter and 1-6 millimeters in height. Lithium sizes can be determined from their reference numbers. The first two digits refer to the diameter of the battery in mm and the second two digits give the height or thickness of the battery in tenths of mm. So, for example, a CR2032 is a Lithium button cell which is 20 mm in diameter and 3.2 mm thick. A CR2430 is a lithium battery, 24 mm in diameter and 3.0 mm thick. Lithium button and coin cell batteries have a BR or CR prefix and primarily provides 3 volts.
