CR2032W can be customized for additional processing, add solder chip terminals, insulation packaging and configuration type, the model as following: CR2032W/HC5. The basic parameters of this CR2032W battery are as follows: 3V 210mAh, size is 20*3.2mm, temperature is -40~125°C. From the Discharge 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 3.0V, and the voltage drops with the increase of capacity. When the capacity reaches 100mAh, the voltage drops to 2.8V. When the capacity reaches 150mAh, the voltage drops to 2.5V. As the capacity increases, the voltage continues to drop until the voltage discharge ends. When used at an ambient temperature of 60 ° C, the voltage is 3.05 V, and the voltage drops with increasing capacity. When the capacity reaches 100 mAh, the voltage drops to 3.01 V. When the capacity reaches 200 mAh, the voltage drops to 2.85 V. The increased voltage of the capacity continues to drop until the end of the voltage discharge. When used at an ambient temperature of 100 ° C, the voltage is 3.1 V, the voltage decreases with increasing capacity. When the capacity reaches 100 mAh, the voltage drops to 3 V. When the capacity reaches 150 mAh, the voltage drops to 2.95 V. The increase in capacity continues to drop until the end of the voltage discharge.
