high quality panasonic lithium battery series for flashlight

The basic parameters of this wide temperature battery are as follows: CR2032B 3V210mAh, size 20*3.2mm, temperature is -40~120 °C. From the following Discharging Characteristics by Temperature, 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 3V. When used for 200h, we can see that the voltage drops to 2.6V. After 800h, the voltage drops to 2.6V. After 1000h, the voltage drops rapidly to 2.49V. And the apparent decline is accelerated until the end of about 1150h. When used at 0 °C ambient temperature, the voltage is 3V. When using 200h, we can see that the voltage drops to 2.8V. After 800h, the voltage drops to 2.76V. After 1000h, the voltage drops rapidly to 2.65V. And the apparent decline accelerated, until the end of about 1160h. When used at an ambient temperature of 20 ° C, the voltage is 3V. When used for 200h, we can see that the voltage drops to 2.9V. After 800h, the voltage drops to 2.76V. After 1000h, the voltage drops rapidly to 2.6V. And the apparent decline accelerated, until the end of about 1155h. When used at an ambient temperature of 60 ° C, the voltage is 3.1V. After using 200h, we can see that the voltage continues to stay at 3.2V. After 800h, the voltage will slowly decrease, dropping to 2.8V, after 1000h. The voltage drops rapidly to 2.65V and the apparent drop accelerates until the end of about 1150h. When used at an ambient temperature of 85 ° C, the voltage is 3.2V. After using 200h, we can see that the voltage continues to stay at 3.2V. After 800h, the voltage will slowly decrease, down to 2.96V, after 1000h. The voltage drops rapidly to 2.6V and the apparent drop accelerates until about 1160h ends.
