CTECHi maxell lithium battery customized for smart meter

The basic parameters of this CR2050HR battery are as follows: 3V350mAh, size 20*5.0mm, temperature is -40~125°C. From the temperature characteristics below you can see how the battery operates at the same load and at different temperatures. When used at an ambient temperature of 20 ° C, the voltage is 3.0 V, the voltage gradually decreases with the use of time, after 300 h, the voltage is 2.8 V, after 600 h, the voltage drops slightly to 2.6 V, after 700 h, the voltage is used At 2.4V, and continue to decline until about 720h, we can see that the battery is used for a longer period of time at room temperature. When used at an ambient temperature of 80 ° C, the voltage is 3.1V, the voltage gradually decreases with the use of time, after 300h, the voltage drops to 3.0V, after 600h, the voltage slowly drops 2.8V and continues to decline until 680h end. When used at an ambient temperature of 125 ° C, the voltage is 3.2V, the voltage gradually decreases with the use of time, after 300h, the voltage drops to 3.0V, after 500h, the voltage slowly drops 2.8V and continues to decline until 545h at the end, we can see how long the battery lasts for a long time at high temperatures.
