How to properly treat lithium batteries in winter
1. Do not use lithium batteries in low temperature environments
Temperature has a great impact on lithium batteries. the weaker the lithium battery, the lower the activity, which directly leads to a significant reduction in charging and discharging efficiency. Generally speaking, the operating temperature of lithium batteries is between -20 degrees and 60 degrees.
When the temperature is below 0°C, be careful not to charge outdoors. You cannot charge it even if you charge it. We can take the battery inside to recharge it (be careful, be sure to stay). away from flammable materials!!!), when the temperature is lower than -20℃, the battery automatically enters the sleep state and cannot be used normally. It is therefore particularly suitable for users of regionalns cold of the north.
If there is really no charging condition indoors, you should make full use of the waste heat when the battery is discharged and charge it in the sun immediately after parking to increase the capacity of charge and avoid lithium deposition.

Determined according to winter temperature and personal usage habits, but under normal circumstances it will decrease by about 10%.
Lithium batteries can generally be charged and discharged 300 to 500 times. It is better for lithium batteries to be partially discharged rather than fully dischargeddischarged, and try to avoid frequent complete discharges. Once the battery is disconnected, the clock begins to move.
Whether used or not, the lifespan of lithium batteries is only a few years. The decrease in battery capacity is due to an increase in internal resistance caused by oxidation (which is the main cause of the decrease in battery capacity). Eventually, the battery resistance will reach a certain point. Although the battery is fully charged at this time, it cannot release the stored energy.
If possible, charge the battery to 40% and place it in a cool place. In this way, the battery protection circuit can work for a long time. If the battery is placed in high temperature after being fully charged, it will cause serious damage to the battery.
Therefore, when using a fixed power supply, the batterye is in a fully charged state and the temperature is generally between 25-30°C, which will damage the battery and cause its capacity to decrease.

Notes on extending the capacity and life of lithium batteries;
1. If you use an external power supply. power supply for your laptop for a long time, or if the battery charge has exceeded 80%, remove the battery immediately. There is no need to fully charge the battery during normal charging, just charge it to around 80%. Adjust the operating system power options and set the power alarm above 20%. The minimum battery power should not be less than 20%.
2. For mobile phones and other small electronic devices, the power cord (including USB interface for charging functionement) should be unplugged immediately after charging. Keeping it connected will damage the battery. Charge frequently, but it is not necessary to fully charge the battery.
3. Whether it's a laptop or mobile phone, be careful not to let the battery run out (automatic shutdown).
4. If you want to travel, you can fully charge the battery, but charge electrical devices at any time if conditions permit.
5. Use a smarter, more energy-efficient operating system.
