Lithium-based batteries typically have a life of 2-3 years. This time starts from the battery production line. The capacity loss is reflected in an increase in internal resistance due to oxidation. Eventually, the internal resistance of the battery will reach the peak of the inability to store electrical energy, even if it is continuously charged for a long time.
In daily use, the following methods can be used to increase the life of the lithium battery:
First, do not carry over 12 hours of ultra-long charging
For the "activation" problem of lithium batteries, many claims are: charging time must be more than 12 hours, repeated three times in order to activate the battery. This statement that "the first three charges have to be charged for more than 12 hours" is obviously a continuation of nickel batteries (such as nickel cadmium and nickel hydride). So this kind of statement can be said to be misinformation at the beginning.
Charging** Charges according to standard time and standard methods, especially for over 12 hours of extra long charging. Usually, the charging method described in the mobile phone manual is a standard charging method suitable for the mobile phone.
Second, put the lithium battery in a cool place
A high state of charge and increased temperature will accelerate the decline in battery capacity. If possible, try to charge the battery to 40% in a cool place. This allows the battery's own protection circuit to operate for a long period of time.
If the battery is placed at a high temperature after being fully charged, it will cause great damage to the battery. (So ​​when we use a fixed power supply, the battery is fully charged at this time, the temperature is usually between 25-30 ° C, which will damage the battery, causing its capacity to drop).
Do not expose the battery to high temperatures or cold weather. When it is three days old, the mobile phone should not be placed under the sun and exposed to the sun; or it should be taken in an air-conditioned room and placed in a place where the air is blown straight.
Third, to avoid recharging after the battery is fully used up
The life of the battery is determined by the number of repeated charge and discharge cycles. The lithium battery can be charged and discharged continuously for about 500 times. After that, the performance of the battery will be greatly reduced. The residual power in the battery should be avoided and recharged. Otherwise, the number of times of charging increases. The battery performance will gradually weaken, and the standby time of the battery will not be difficult to drop.
Fourth, the use of dedicated charger
Lithium-ion batteries must use a dedicated charger, otherwise it may not reach saturation, affecting its performance. After charging, avoid placing it on the charger for more than 12 hours. When not in use for a long time, separate the battery from the mobile phone. ** Use a charger from an original or reputable brand.
Battery technology is still a key area of ​​research and development in the IT industry. It is expected that disruptive technology will greatly increase the life of lithium batteries in the future. ?
