The basic parameters of this battery are as follows: 3V120mAh, size 16*3.2mm, temperature -30~80°C. BR1632 can be customized for additional processing, add solder chip terminals, insulation packaging and configuration type, the model as following: BR1632/V1AN, BR1632FAN, BR1632/GAN, BR1632/HAN, BR1632/VAN.
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 -10 °C, the voltage is 2.5V. When using 250h, we can see that the voltage rises to the peak. This is because the internal chemical reaction of the battery is active, the voltage reaches 2.6V, after 500h. The voltage drops to 2.55V, using 750h, the voltage is restored to 2.5V, and the significant drop is accelerated until the end of about 1200h.
When used at an ambient temperature of 20 ° C, the voltage is 2.8V, after 250h, the voltage is maintained at 2.8V, after 500h, the voltage drops slightly to 2.75V, using 750h, the voltage is 2.7V, after 1000h, the voltage drops To 2.65V and continue to decline.
When used at an ambient temperature of 60 ° C, the voltage is 2.9V. After 250h, the voltage rises slightly to 2.92V. After 500h, the voltage is kept at 2.92V. After 750h, the voltage continues to be 2.92V. After 1000h, the voltage is used. Slowly decreased by 2.9V and continued to decline.
