Micro button type battery features

Batteries are used mostly directly or indirectly in everyday life. Small button battery is one of them, such as TV remote control, children's electric toys, electronic calendar, alarm clock and so on. Most of them can touch the battery directly. For example, micro-button battery, in the computer, mobile phone, precision electronic instruments and so on, most can not directly contact the battery, so what are the characteristics

What is a micro-button battery?

The capacitor energy density of the micro-button battery is higher and can store 460-600Wh/kg of energy. It has a 3.7V or 3.2V power saving meter, but it is very lightweight. Compared with the same weight of lead-acid battery, its size is about one-fifth of lead-acid battery, service life is as long as 6 years, in -20 to 60 degrees Celsius and low temperature working environment, and does not contain lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances.

The micro-button battery is a kind of lithium battery, namely the button type lithium battery. It has the characteristics of small size, large capacity, safety, environmental protection and easy recycling. It comes in a variety of specifications and models and can be applied to a variety of equipment requirements. It has a voltage of 3 volts.

The micro-button battery is CR ###, and the size range is 4.8mm to 30mm in diameter and 1.0mm to 7.7mm in height. These models are distinguished by diameter and height. For example, the 11.6x3.0mm model is CR1130, 12.5x2. The 5mm model is CR1225, which is the integer part of the diameter plus the high integer plus the decimal.

Installation method of small button battery

Take the laptop motherboard. The above CMOS battery is usually a 2032 button type lithium battery. When installed, the negative terminal of a button lithium battery is flat and needs to be connected to a spring. The positive side is the protruding side. Connect the protruding battery, that is, press the side with the letter in and then press it into the battery slot.
