China OEM universal notebook power adapter factory

Many friends have such problems more or less: after using the notebook you bought for two or three years, you’ll find that its battery is not working.

How to use the notebook battery correctly and prolong the service life of our notebook? After reading this blog, I believe you will have a clear answer.

Why is the service life of lithium battery only 500 times?

The reasons for battery power attenuation are no more than several factors, that is, the falling off and aging of battery anode and cathode materials, the increase of internal resistance caused by the decomposition and regeneration of SEI film, the lithium precipitation caused by overcurrent and low temperature, the diaphragm damage caused by high-temperature overcharge, the decomposition and loss of electrolyte caused by overcharge, and the influence of collector oxidation on electronic conductivity.

In short, the continuous charging and discharging of lithium batteries has changed its internal chemical properties, resulting in the dissolution and aging of some materials, and the battery is not disabled more and more.

The life of a lithium polymer battery depends on the times of charge and discharge. The mainstream view is that 300-500 times in the life cycle of a lithium polymer battery, that is, 300-500 times of charge and discharge (different brands, different technologies, and different usage habits will lead to different life).

The battery will be attenuated by 20% (loss of the battery itself), and the theoretical battery capacity is only 80% (usable power). Generally, we will replace the battery with less than 80%.

How can we extend the battery life of the notebook?

• Try to use the power directly at ordinary times

In general, we recommend using the power supply when it can be used, and there are many benefits of using the power supply for notebooks. First, when using the power supply, the performance of the processor must be higher than that when using the battery.

Secondly, after the power supply is connected, the battery will no longer be charged and discharged, which reduces the number of battery cycles to a certain extent.

• Ensure that it can be used at the appropriate temperature

Under normal circumstances, the use of notebooks in our indoor environment will not cause abnormal battery temperature, except for extreme scientific tests.

Lithium polymer battery has certain properties. When the temperature is high, the activity of lithium-ion is enhanced, and the self-discharge will be accelerated. At the same time, using the battery in an environment higher than 60 degrees will cause irreversible damage to the battery.

Under low temperature, it will promote the plating of metal on the battery anode, which may also cause an internal short circuit, generate heat and make the battery unstable and unsafe.

That's why our computers suddenly run out of power in extremely cold conditions. To extend battery life, you must avoid using notebooks when they are too cold and overheated.

• Charge it even if you don't use it for a long time

Because the battery usually has a power management System BMS, we generally don't need to worry about the overcharge of the notebook, but we still need to pay more attention in case of excessive discharge.

Make a purchase of laptop batteries from China, you can get them at a good price if you have a large quantity. We hope to be your long-term partner.
