Avoid using it under harsh conditions, such as: high temperature, high humidity, long-term exposure to the sun in summer, etc., and avoid throwing the battery into fire.

When removing the battery, make sure that the electrical appliances are powered off; the operating temperature should be kept between -20~50°C

Avoid long-term "storage" of batteries in electrical appliances that are out of use

Use of lithium-ion batteries

  1. How to charge a new battery? When using a lithium battery, it should be noted that the battery will enter a dormant state after a period of time. At this time, the capacity is lower than the normal value, and the use time is also shortened.

But lithium batteries are easy to activate, as long as the battery can be activated after 3-5 normal charge and discharge cycles, the normal capacity can be restored. Due to the characteristics of the lithium battery itself, it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone does not need special methods and equipment during the activation process.

For the "activation" of lithium-ion batteries, many say: charging time must be more than 12 hours, if you do this three times, in order to activate the battery. This saying that "the first three charges should be charged for more than 12 hours" is obviously a continuation of the nickel battery (such as nickel cadmium and nickel metal hydride). So this kind of statement can be said to be a misinformation from the beginning. The charging and discharging characteristics of lithium batteries and nickel batteries are very different, and I can tell you very clearly that all serious formal technical information I have checked emphasizes that overcharging and over-discharging will affect lithium batteries, especially liquid lithium batteries. Ion batteries do a lot of damage. Therefore, it is best to charge according to the standard time and standard method, especially do not perform super-long charging for more than 12 hours (the charger can only be fully charged). the

In addition, lithium batteries or chargers will automatically stop charging after the battery is fully charged, and there is no so-called "trickle" charging that lasts for more than 10 hours with nickel chargers. That is to say, if your lithium battery is fully charged, it will be charged in vain on the charger. And none of us can guarantee that the characteristics of the charging and discharging protection circuit of the battery will never change and the quality will be foolproof, so your battery will be on the verge of danger for a long time. This is another reason we are against long charging.

In addition, another aspect that cannot be ignored is that lithium batteries are also not suitable for over-discharge, and over-discharge is also detrimental to lithium batteries. the

  2. When should you start charging in normal use? You can often see this saying, because the number of charge and discharge is limited, so you should use up as much power as possible to recharge the battery of the mobile phone. In fact, the life of the lithium battery has nothing to do with this. The following can be an example of an experimental table about the charge and discharge cycle of a lithium-ion battery. The data about the cycle life is listed as follows: Cycle life (10%DOD): >1000 cycles Abbreviation for Depth. It can be seen from the table that the charging times are related to the discharge depth, and the cycle life of 10% DOD is much longer than that of 100% DOD. Of course, if it is converted to the relative total capacity of actual charging: 10%*1000=100, 100%*200=200, the latter’s full charge and discharge is still better, but the previous netizen’s statement needs to be corrected: in normal Under certain circumstances, you should reserve and charge according to the principle of recharging when the remaining battery power is used up, but if your battery is expected to be unable to last the whole day on the second day, you should start charging in time. It's another matter if you bring the charger to the office.

The principle of recharging the remaining battery power is not to make you go to extremes. A saying that is as widespread as long charging is to "use up the battery as much as possible". This practice is actually only a practice on nickel batteries, the purpose is to avoid the memory effect, unfortunately it is also circulating on lithium batteries. There was an example where someone continued to use the mobile phone without charging after the warning that the battery level of the mobile phone was too low appeared until it was automatically shut down. As a result, the mobile phone in this example did not respond during the subsequent charging and booting, and had to be sent to customer service for repair. This is actually caused by the low voltage of the battery due to over-discharge, so that it does not have normal charging and starting conditions. the

Personally, I suggest that the lithium-ion battery of the mobile phone should not be overcharged or run out of power. Charging the battery before it is exhausted will not cause damage to the battery. It is advisable to charge within 2-3 hours, and it does not have to be fully charged. But every 3-4 months or so, the lithium battery should be fully charged 1-2 times (normal charging time) and fully discharged. Lithium batteries that have not been used for a long time should be stored in a cool and dry place. It is best to use a half-charged state (70--80% of the full charge, if your mobile phone shows 4 bars when it is fully charged, then 3 bars are enough). Storage with full charge is dangerous and the battery will be damaged, and storage without charge will damage the battery. Every 3-6 months, check whether to add electricity.

Lithium-ion batteries can be divided into liquid lithium-ion batteries and polymer lithium-ion batteries according to the electrolyte. The electrolyte of polymer lithium-ion batteries is colloidal and will not flow, so there is no leakage problem and it is safer.
