Introduction to the correct charging method of lithium batteries
The following is the correct way to charge lithium batteries to help extend battery life and ensure safety:
I. Key Points for Daily Charging
Avoid overcharging and overdischarging
Not fully charged to 100% : Lithium batteries do not need to be charged to 100% each time. It is recommended to charge them to 80%-90% (some devices support the "optimized charging" function, which can be enabled to reduce battery wear and tear).
Do not drain the battery: Try to charge when the battery is remaining at 20%-30%, and avoid over-discharging (discharging below 5% May damage the battery).
Use the original charger
Give priority to using the charger that comes with the device or a certified third-party charger to avoid unstable voltage, overheating or potential safety hazards caused by inferior chargers.
The charging environment is suitable.
Temperature: Avoid charging in high-temperature environments (such as direct sunlight inside the car) or low-temperature conditions. The ideal temperature is around 25℃ (high temperatures can accelerate battery aging, while low temperatures may cause charging to slow down or temporarily stop working).
Ventilation: Ensure good heat dissipation of the device during charging and keep it away from flammable materials such as bedding and clothing.
Second, optimize charging habits
Charge it as needed without the need for deliberate cycle charging
Lithium batteries have no "memory effect" and do not require a complete charge and discharge cycle. They can be charged at any time, and maintaining their charge within the range of 30% to 80% is more conducive to extending their lifespan.
Avoid long-term storage with full charge
If the device needs to be stored for a long time (such as more than one month), it is recommended to charge it to 50%-60% and then turn it off. Recharge the battery every three months (storing it fully charged will accelerate the battery's self-discharge and aging).
Reduce the use while charging
Playing large-scale games or running high-power applications while charging can cause the battery to heat up and accelerate its wear and tear. If you need to use it, try to choose a scene with low brightness and few background tasks.
Iii. Precautions for Special Scenarios
Mobile phone/laptop
Turn off power-consuming functions such as "Background Application Refresh" and "Location Service" to reduce the load during charging.
When a laptop is plugged in for a long time, you can activate the "Battery Protection Mode" to limit the charging to around 80%.
Electric vehicle/energy storage battery
Avoid charging when the battery temperature is too high (such as right after riding) or too low. Wait for 30 minutes before charging to cool or warm up.
Regularly check whether the battery interface is loose or oxidized to ensure good charging contact.
Safety first
If you notice the battery bulging, abnormal heating, smoke coming out of the charging port or an unpleasant smell, stop using it immediately and contact a professional for handling. Do not continue charging or disassemble it by yourself.
Iv. Other suggestions for Extending Battery Life
Regularly clean up background programs: Reduce unnecessary power consumption of applications and lower the charging frequency.
Avoid frequent fast charging: Although fast charging is convenient, long-term use may accelerate battery degradation. In daily life, you can alternate between regular charging.
Update system/firmware: The manufacturer may optimize the battery management logic through updates. It is recommended to upgrade in a timely manner.
By adopting reasonable charging habits, the cycle life of lithium batteries (typically 300 to 500 complete charge and discharge cycles) can be significantly extended, maintaining stable battery life for the device.
