How long does it take to charge a lithium battery normally?

Lithium battery charging time (h) u003d battery capacity (mAh) u0026 pide; charging current (mA). But in order to offset the influence of impedance, the actual charging time should be longer than the theoretical charging time. In order to make the charging time of the lithium battery meet the requirements of full charging in practical applications, a coefficient greater than 1 should be set according to the ratio of the charging current to the battery capacity. It is useful. The charging time of lithium batteries in portable electronic products is also in accordance with the above formula. Regarding lithium batteries, they are usually equipped with corresponding constant current chargers. The control of the lithium battery charger controls the charging time of the lithium battery. Therefore, consumers only need to follow the instructions without worrying about how long the lithium battery is suitable for charging. At present, lithium battery chargers for electric vehicles are all three-stage charging, which can be divided into constant voltage, constant current and fine current levels. The first two stages are important stages of charging. After charging, the battery is basically full, the indicator light turns green, and it enters the dripping stage to protect the battery. At this time, do not unplug the power and continue charging for 1-2 hours, which can effectively extend the battery life, but do not exceed 8 hours after turning green. In addition, it should be noted that the lithium battery should not be activated during the new battery stage. In daily use, lithium batteries must be charged normally only when the battery is dead. When the battery is dead or low, continuous use of the battery will affect the battery life. The first charging time of the lithium battery can be determined according to the actual battery capacity. Many people charge lithium batteries for 8 to 9 hours for the first time. In fact, there is no need to charge for such a long time. Currently, most mobile phones are smart phones with large screens and fast power consumption. Even a large-capacity lithium battery must be charged once a day if the phone is used for a long time. People who consume electricity quickly can keep the charger or spare battery. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
