What are the common misconceptions about lithium batteries

Misconception 1. Firstly, it is necessary to completely discharge and then completely charge, repeat three times in order to activate the battery. Otherwise the battery will never work! Answer: If you really have nothing to do, you can do it, but it is not necessary, because the activation operation is not necessary for the first use. As long as it is continuously used, the electrode passivation can slowly disappear without deliberate activation. Myth #2: Do not use your mobile phone when charging, it is harmful to the battery, and a large amount of radiation can damage the human body. Answer: Whether using a mobile phone during charging is harmful to the battery depends on the situation, but one thing can be determined is that using a mobile phone during charging will definitely not generate more radiation than normal use of a mobile phone. Misconception 3: Lithium batteries can only be charged and discharged XXX times in the life cycle, so try to use automatic shutdown every time you use, and try to charge to full charge every time you charge. The first clause is right, and the following is wrong. Each of these times refers to a complete one. For example, charging from 20% to 30% to stop charging is only 1/10 times. Discharging from 80% to 60% is only 1/5 times. Misconception 4, the first three charging must reach 12 hours, otherwise it will affect the battery function. If it is to activate the battery, it is enough to only need the mobile phone to prompt the charging and overflow. Generally, the mobile phone will prompt the charging within 5 hours. If the charger is continued after completion, the overshoot and overdischarge maintenance circuit will cut off the charging current of the phone. After that, the battery is in a non-operating state, and the effect is the same as removing the charging cable immediately after charging. It is necessary for the first three charges to reach 12 hours for Ni-MH rechargeable batteries. As a result, many manufacturers habitually and ignorantly write in the lithium battery user manual. It is terrible to have no culture. International manufacturers such as Dell, Lenovo, Asus, and Apple will certainly not display words like 12 hours on their products. And with regard to lithium batteries, this is a common feature and part of the operating principle. It is impossible for some manufacturers to process it for 12 hours, while others do not. It should be noted that if you choose a charger, because most chargers do not reach the maximum current of the official line charger, the charging time may exceed 6 hours, but if you only need to charge the battery, the charger will automatically power off. The line charge is the same. Misconception 5, it’s best to remove the charging cable immediately when the battery is overcharged and beware of overcharging. The overshoot and overdischarge maintenance circuit is not a vegetarian, OK! ! ! If overcharge occurs, it is mostly due to damage to the overshoot and overdischarge maintenance circuit, but in terms of current electronic product technology and pressure resistance, this probability is really low, so you don't need to be frightened. Misconception 6, once the device starts to prompt the user to charge, it must be charged immediately, or shut down immediately, and beware of over-discharge. The overshoot and overdischarge maintenance circuit is not a vegetarian, OK! ! ! This circuit will be forced to shut down when necessary (that is, before over-discharge) without damaging the battery. The prompt of the mobile phone is to let the user know in advance, so as to make a solution or psychological preparation in advance. It should be noted that if the mobile phone has been automatically turned off, you must not force it on for the purpose of making a call, because it is likely to cause overdischarge, and because of the existence of maintenance, it will probably be overcharged and overdischarged before the power-on is completed. The maintenance circuit Power off forcibly. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
