The 3 volt lithium button cell can withstand temperatures from -30°C to 80°C. According to official data, the 3 volt lithium button battery can withstand the lowest temperature of -30 degrees Celsius, the highest temperature can reach 80 degrees Celsius, and the longest life can reach 15 years. The rated voltage is 3.0 V. the rated capacity is 600 mAh and the battery size is 24.8 x 5.2 mm.
Does cold weather impact the battery?
The Pacific Automotive Network lithium iron phosphate battery cannot be used when its capacity is reduced by 50%. Lithium iron phosphate decomposes at -10°C to approximately 50% and cannot function above -20°C. The lower limit of ternary lithium is -30°C, and the attenuation degree at the same temperature is lower than that of lithium iron phosphate.
The performance of lithium batteriesm iron phosphate are worse than those of ternary lithium batteries at low temperatures. The capacity of the lithium iron phosphate battery decreases to approximately 50% at -10°C and it cannot operate above -20°C. The lower limit of ternary lithium is -30°C, and the attenuation degree at the same temperature is lower than that of lithium iron phosphate. It's no wonder that ternary batteries have become common. During the Northeast winter, -10 degrees Celsius is common and ternary lithium batteries are no good either. The battery dims 30% at -10 degrees, and better batteries should be developed.
What is a lithium iron phosphate battery?
Lithium iron phosphate battery is a type of lithium ion battery, which refers to a lithium ion battery using lithium iron phosphate as the positive electrode material. It is characterized by security andHigh stability, high temperature resistance and good cycle performance.
The lifespan of lithium iron phosphate batteries is the same as that of ternary lithium batteries. The theoretical lifespan of lithium iron phosphate batteries also exceeds 2,000 charge and discharge cycles. Even if they are charged once a day, they are charged. can last more than five years. Generally speaking, daily home use requires three days of charging, which can last around eight years. However, due to the poor low temperature performance of lithium iron phosphate batteries, the service life of lithium iron phosphate batteries will be relatively longer in the southern region.
At the same time, the battery life of new energy vehicles is also related to the owner's charging and discharging depth and the frequency of aggressive driving. Of course, therealso has the most important technical factor: the battery management system.

It has an impact.
In a low temperature environment, the chemical reaction speed slows down, the electrolyte resistance becomes larger, the lithium ion passing performance deteriorates, the activity decreases, and the discharge current becomes smaller, resulting in a reduction in available battery capacity. In fact, everyone wrongly believes that lithium batteries consume power quickly at low temperatures. The bottom line is that the capacity of the lithium battery itself is reduced.
Experimental data: The power consumption of the same mobile phone at -5°C is 1.7 times higher than that at 20°C. The bottom line is that the lithium battery current decreases, resulting in reduced power consumption. Capacity available.
Detailed information:
When the phone detects that the battery capacity is low and the environment When the temperature is low and the current is low, the temperature protection circuit in the built-in battery protection board is activated and the phone will automatically turn off. When the ambient temperature returns to the normal value, the temperature protection circuitThe phone can only work normally after it is turned off.
In order to avoid the above situation, it is best not to use your cell phone for a long time in low temperature environments. When you go out, you should place your cell phone in a warm place such as. a pocket or bag. You can also buy a thicker cell phone cover to keep warm.
Actually, what is more grave that low temperature is condensation water. When you come indoors after it's cold outside, the warm air in the room condenses as it becomes cold and water vapor is produced on your phone. If water vapor enters the motherboard, the phone will get wet and freeze or fail to boot. Therefore, when the temperature difference is significant, avoid exposing your cell phone outdoors. If you need to make a call, you can plug in headphones. ?
