Lithium batteries will permanently lose their capacity if stored for a long time.
The picture shows the recoverable capacity of rechargeable batteries after 1 year of storage. We can see this for lithium batteries in storage. , high temperature and complete electricity are the two biggest causes of mortality.
The four columns from left to right are:
1. The temperature of the battery storage environment
2. The lithium battery has a total capacity of 40% which can be restored after 1 year of storage
3. Capacity which can be restored after 1 year of storage when the lithium battery is 100% full
4. Capacity that can be restored after 1 year of storage of the nickel-metal hydride battery
As there is no memory effect, lithium-ion batteries can be charged . at any time with limited impact on lifespan. Here is the conceptt battery life. After the battery is charged and discharged N times, the capacity drops to 70% and N is the lifespan. The national standard stipulates that the service life should not be less than 300 times, and the battery can still be used if the actual capacity is reduced to 70%. Additionally, lifespan refers to the number of full charges and full discharges, and partial charges and discharges can be understood as a fraction of the lifespan.
Battery safety
For now, mobile phone batteries are mainly LION batteries (lithium-ion batteries), which are wrapped with LIB liquid lithium-ion batteries and of LPB lithium-ion polymer batteries. . First of all, polymer batteries are safe batteries since they do not have a hard metal shell, they will not explode even in the event of an anomaly. What could explode are liquid lithium-ion batteries qui are mainly encapsulated in metal. Generally speaking, as long as they meet national standards and are produced by regular manufacturers with national production licenses, they will not explode. The reasons are as follows: ① Batteries meeting national standards must use complete protection circuits and safety cells with more than double tubes (overvoltage, overcurrent, undervoltage, etc.). Even if the battery electrode is short-circuited, it will be automatically disconnected by the protection circuit, the output voltage will be zero, and it will not explode. ② Even if the protection circuit is removed, that is, even if the protection circuit fails and the battery cell is directly short-circuited, ordinary batteries that meet national standards are all safety cells in aluminum housing. The intense pro gas release reactioncaused by a short circuit. The circuit and perforation will increase the internal pressure of the battery to a certain level. If the exhaust valve is opened to vent, there will be no explosion. ③ Even if the exhaust valve fails, the soft aluminum shell will inflate due to internal pressure, and when it reaches a certain level, rupture will occur and gas will escape, there will be no will therefore not have an explosion.
New lithium-ion batteries are fully charged: Lithium-ion batteries require transportation and storage in a state of greater than half charge. Low voltage will affect its activity and even cause the protection circuit output to stop. , which makes recharging impossible. If the received lithium-ion battery is very weak or even dead, it means that the battery has been stored for a long time or has excessive self-discharge.
The electricity of the newThe new battery is charged at the factory with a high current. The polarization is severe and the energy efficiency is not good. Therefore, the first three uses of lithium-ion battery. should be carried out after the phone naturally shuts down (do not force it repeatedly after shutdown. Turning on the phone may cause cell phone or battery protection, cut off the output and make charging impossible), then use the phone to. Connect to the original direct charger or original smart cradle charger (it is recommended not to use non-original ordinary cradle chargers) and continue charging for about 1-2 seconds after fully charging for an hour .
LithiumThe charging and discharging characteristics of batteries and nickel batteries are very different. All official technical data emphasizes that overcharging and overdischarging will cause enormousdamage to lithium batteries, especially liquid lithium-ion batteries. Therefore, it is best to charge according to standard time and methods, especially not to charge for more than 12 hours. Usually, the charging method described in the mobile phone manual is the standard charging method suitable for the mobile phone. In fact, shallow discharge and shallow charge are more beneficial for lithium batteries. Deep discharge and deep charge are only necessary when the product's power module is calibrated for lithium batteries. Therefore, products powered by lithium batteries do not need to stick to the process. Everything is done first with convenience. Charge at any time without worrying about affecting the battery life.
Also, a few, like Nokia, have officially announced in the product manual that they require that the batteryie be charged for 12 seconds the first three times -14 hours. It is indeed possible to charge the new battery as the manager said. However, you can try it and see. There is not much difference between charging the new battery for 5 hours and 12 hours. And remember not to charge more than 10 hours at a time for lithium batteries, it does a lot of damage.
