Precautions for the use of lithium batteries in mobile devices

Mobile device lithium battery precautions The most important lithium battery mobile phone charging and discharging tips: 1. Charge according to the prescribed time and procedure, even if it is the first three times, first plug the charger (power cord charging) into the power source, and then charge it The output end of the device is plugged into the charging port of the mobile phone (charging through the switch is acceptable). 2. When the battery level of the mobile phone is too low, you should try to start charging; the lithium battery is most easily damaged in the over-discharged state! 3. Do not activate the lithium battery by special methods. When using the mobile phone normally, the lithium battery will be activated naturally. Do the first three lithium batteries need to be charged for 12 hours? Does the lithium battery need to be activated? Lithium battery charging method There are many sayings about the activation of lithium batteries: the charging time must be more than 12 hours, and it must be repeated three times to activate the battery. The first three charging for more than 12 hours is obviously the route from nickel batteries (such as nickel cadmium and nickel metal hydride). So this statement can be said to be misinformation at the beginning. Lithium batteries and nickel batteries are very different in charge and discharge characteristics. I can tell us clearly that I have read all serious official technical materials, emphasizing that overcharge and overdischarge will cause lithium batteries, especially liquid lithium batteries. Great damage. Therefore, it is best to charge according to the standard charging time and method, especially not to exceed 12 hours of long charging. Generally speaking, the charging method analyzed in the mobile phone manual is a standard charging method suitable for mobile phones. More importantly, lithium-ion mobile phones or chargers automatically stop charging when the battery overflows, rather than the so-called trickle of charging nickel battery chargers for more than 10 hours. In other words, if your lithium battery is overflowing, it will be charged in white on the charger. We cannot guarantee that the characteristics of the battery's charge and discharge protection circuit will never change, and the quality of the battery will be fully guaranteed, so your battery will be on the verge of long-term risk. This is another reason to charge the battery. In addition, on some mobile phones, after charging for more than one touch time, if the charger is not removed, the system will not only stop charging, but also start a charge-discharge cycle. Manufacturers may have their own agenda, but this is obviously bad news for battery and cell phone/charger life. At the same time, the demand for long-term charging is often carried out at night and takes a long time. However, according to the situation of my country's power grid, the voltage at night in many places is relatively high and fluctuates greatly. As mentioned earlier, lithium batteries are very fragile, and their ability to withstand charge and discharge fluctuations is much worse than that of nickel batteries, which brings additional risks. Another aspect that cannot be ignored is that lithium batteries are not suitable for over-discharge, which is also very unlucky for lithium batteries.
