New method for lithium battery maintenance: "short discharge and short charge" for the longest durability

Count how many mobile devices you have around you now? Mobile phones, MP3s, tablet computers, laptops, digital cameras, handheld game consoles, navigation systems, etc. These devices are all powered by mobile batteries, and the battery life is also the most worrying issue.

Take mobile phones as an example. In addition to system power consumption factors, how to maintain the battery is also something you must know. Unless you can bear to replace the backup battery or external battery, in fact, mobile phones like iPhones cannot even replace the battery.


Battery maintenance may not have much effect on a single charge and discharge cycle, but after a long time, there will be a comparison. After a lithium-ion battery is used for a year or more, the battery capacity will be lost, and the loss of a well-maintained battery will be much better.

There have been many methods for lithium-ion battery maintenance on the Internet before, but the opinions are different. For example, after a new battery is brought back, it must be fully charged for 12 hours and then emptied. It takes three consecutive times to activate the maximum capacity. There is also a saying that a full charge and discharge process must be performed once a month to facilitate maintenance.

The foreign Battery University website recently released an article on how to extend the life of lithium batteries, and put forward new conclusions on the use of batteries.

They claim that the best way to maintain lithium-ion batteries is to use them lightly, discharge them quickly, and charge them quickly. This is similar to the use of mechanical equipment. The more frequently and the more times they are used, the faster the battery will lose. The less deep discharge of a lithium battery is, the longer it can be used. If possible, try to avoid frequent full charge and discharge.

For users, it is best to charge your battery when it has been used up to 10% or 20%. It is also OK to charge it when the remaining power is 50%, but try to avoid charging when the phone prompts that the battery is low. Do not use up the battery under any circumstances. If you are out and about, try to use a battery with a larger capacity or a mobile power bank.

In addition, they also pointed out that the temperature of the use environment also affects the battery life. Too high (30℃) or too low temperature will cause loss of battery life. For example, if a laptop is often connected to an adapter power source, it is best to remove the battery. In fact, this is not charging that will damage the battery, because the battery will no longer charge after it is fully charged, but if the laptop is not used with ventilation at the bottom, it will overheat, which is the real culprit affecting the battery life. Of course, if there is a better use environment or heat dissipation base, the battery can avoid the loss of unsaved data during a power outage.
