A new method for maintaining lithium-ion batteries
How many mobile devices do you have now? Cell phones, MP3 players, tablets, laptops, digital cameras, handheld devices, GPS navigators, etc. are all powered by batteries, and battery life is an important issue.
In the case of mobile phones, in addition to the power consumption of the system, it is also necessary to maintain the battery, unless you can tolerate replacing the battery with a spare or external battery, just like iPhones where the battery cannot even be replaced.
Battery maintenance may not have a significant impact on a single charge-discharge cycle, but over a long period of time, lithium-ion batteries will experience capacity loss after more than a year of use, while well-maintained batteries will show much less loss.
There are many maintenance methods for lithium-ion batteries online, but they vary. For example, some say that a new battery should be fully charged for 12 hours before being used up, and this should be repeated three times to activate its maximum capacity. Others say that a complete charge and discharge cycle must be performed every month for maintenance.
A recent article on the Battery University website on how to extend the life of lithium-ion batteries offers new conclusions on how to use them.
They claim that experiments have shown the best way to maintain lithium-ion batteries is through light use and quick charging, similar to using mechanical equipment. The smaller the depth of discharge, the longer the battery life; if possible, avoid frequent full charge-discharge cycles.
For users, it's best to charge the battery to 10% or 20%, and it's acceptable to charge it to 50%. However, try not to start charging when your phone tells you it's low, and under no circumstances should you use the battery. If you're not at home, try to use a larger battery or a portable power source.
Furthermore, technicians point out that ambient temperature affects battery life; excessively high (30°C) or low temperatures can both cause battery loss. When using a laptop connected to an adapter or other power source, it's generally best to remove the battery. While this doesn't actually damage the battery's internal structure as it stops charging once full, poor ventilation on the bottom of the laptop can cause overheating, which is an unpredictable factor affecting battery life. Of course, a better usage environment or a cooling pad can prevent the loss of unsaved data when the battery is disconnected.
