Precautions to ensure lithium-ion battery capacity and lifespan:
Currently, most electronic products use lithium-ion batteries. Since their introduction in 1990, lithium-ion batteries have experienced rapid development and widespread application due to their superior performance, leading to the largest-scale growth of lithium-ion battery manufacturers. Do not charge lithium-ion batteries to 100% full, and never completely drain them. When possible, keep the battery level around half-full; the smaller the charging and discharging fluctuations, the better.
The Chevy Volt electric car is designed to keep its battery charge between 20% and 80% from the factory, and Apple's laptops (as well as some other laptops and electronic products) may also use this method to increase the number of charge-discharge cycles.
Do not leave lithium-ion batteries (especially laptop lithium-ion batteries) running for extended periods while the device is connected to external power. Even if your laptop has good cooling, keeping it at 100% charge for a long time is tantamount to killing the lithium-ion battery.
1. If you are using an external power source to power your laptop for extended periods, or if the battery level is above 80%, immediately remove the laptop battery. When charging, do not fully charge the battery; charge it to around 80%. Adjust the operating system's power options to set the battery warning level above 20%. Never let the battery level drop below 20%, and charge it before it reaches 20%.
2. For small electronic devices such as mobile phones, the power cord (including USB charging ports) should be disconnected immediately after charging. Leaving it plugged in will damage the battery. Charge it frequently, whenever you remember, but it is not necessary to fully charge the battery.
3. Whether it's a laptop or a mobile phone, never let the battery run completely drained;
4. If you are going on a trip, make sure the battery is fully charged. However, please remember to charge your devices whenever possible. To extend battery life, never let the battery run completely dry.
