What are the hazards of long charge and deep charge of lithium-ion batteries

Long charging may lead to overcharging. 18650 lithium ion batteries, polymer lithium ion batteries, and lithium iron phosphate lithium ion battery chargers will automatically stop charging after the battery is fully charged. There is no such thing as a trickle charge of nickel battery chargers that lasts for more than 10 hours. In other words, if your lithium-ion battery is fully charged, it is also white charged on the charger. And none of us can guarantee that the characteristics of the battery's charging and discharging protection circuit 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 why we oppose long charging. On some machines, after charging for more than a certain period of time, if the battery charger is not removed, the system will not only stop charging at this time, but also start a discharge-charge cycle. Perhaps the manufacturer of this approach has its own purpose, but it is clearly detrimental to the life of the battery. At the same time, long-term charging takes a long time, often at night. 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-ion batteries are very delicate, and their ability to withstand fluctuations in charging and discharging is much worse than that of nickel batteries, so this brings additional dangers. In fact, shallow charging and shallow charging are more beneficial for lithium-ion batteries. Only when the product's power module is calibrated for lithium-ion batteries, it is necessary to deep discharge and deep charge. Therefore, products powered by lithium-ion batteries do not need to be constrained by the process. Everything is convenient and can be charged at any time.
