Panasonic lithium batteries series for flashlight CTECHi

BR1632A can be customized for additional processing, add solder chip terminals, insulation packaging and configuration type, the model as following: BR1632A/GAN, BR1632A/HAN, BR1632A/VAN, BR1632A/FAN. The basic parameters of this BR1632A battery are as follows: 3V120mAh, size 16*3.2mm, temperature between -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 -10 ° C, the voltage is 2.45V, slowly, we can see the voltage rises to the peak, this time because the internal chemical reaction of the battery is more active, slowly, the voltage slowly drops, when used After 250 h, the voltage reached 2.55 V. After 500 h of use, the voltage dropped to 2.5 V and the apparent drop accelerated until approximately 650 h ended. When used at an ambient temperature of 20 ° C, the voltage is 2.7V, slowly, we can see the voltage rises to the peak, this time because the internal chemical reaction of the battery is more active, after 250h, the voltage is maintained at 2.75V, when After 750h, the voltage dropped slightly to 2.72V. After 1000h, the voltage went to 2.6V and continued to drop until the end of about 1400h. We can see that the battery is used at room temperature for a longer period of time. When used at an ambient temperature of 60 ° C, the voltage is 2.9 V, the voltage gradually decreases with the use of time, after 250 h, the voltage rises slightly to 2.86 V, after 1000 h, the voltage slowly drops 2.75 V and continues to decline until The end of 1300h. When used at an ambient temperature of 125 ° C, the voltage is 3.05V, slowly, we can see the voltage rises to the peak, this time because the internal chemical reaction of the battery is more active, after 250h, the voltage is 3.15V, when After 750 h, the voltage dropped slightly to 3.01 V. After 1000 h, the voltage dropped slightly to 2.85 V and continued to drop until about 1200 h ended. When used at an ambient temperature of 150 ° C, the voltage is 3.15V, slowly, we can see the voltage rises to the peak, this time because the internal chemical reaction of the battery is more active, after 250h, the voltage is 3.2V, then As the duration of use changes, the voltage slowly drops. After 750 hours of use, the voltage drops slightly to 3.01V and continues to drop until about 950 hours. We can see that the voltage of the battery at high temperature changes with the length of use.
