Can ordinary chargers charge lithium-ion batteries?

Ordinary chargers cannot charge lithium-ion batteries, because ordinary battery chargers are generally set to two-stage or three-stage charging mode, and the voltage levels of ordinary batteries and lead-acid batteries do not match. There are many types of lithium-ion batteries, and battery performance and battery protection board parameters may be different. Therefore, lithium-ion batteries are not the same as ordinary batteries, and there are universal battery chargers. Generally speaking, lithium-ion batteries are equipped with special chargers when they leave the factory. In order to protect the lithium-ion battery, a dedicated charger is required. The voltage of the ordinary charger is too high and the current is too large to meet the charging conditions of the lithium-ion battery. The charge termination voltage of an 11V lithium-ion battery should be 12.5V, and the charging current range is 0.1 to 1.5 times the capacity of the lithium-ion battery. In order to extend the battery life, it is generally better to use 0.1 times, and 0.5 times can be quickly charged. Li-ion battery charging control is to charge according to a constant current first, and then when the battery voltage rises to 4.2V, the voltage does not rise again, the charger detects the current, and if the current is less than a certain value, the charging ends. Lithium batteries are sensitive to overcharge, so the protection circuit is complicated. For a single cell with a nominal 3.6V battery, the highest charging rated voltage is 4.2V, and the allowable upper limit of error is not more than 1%. If the charging specifications of different mobile phone chargers are the same, the size of the charging port is also suitable and can be mixed. The charger of the same specification will not damage the battery, but if the specification is different, such as the voltage or power is too high, it is likely to damage the mobile phone battery. It is recommended to use the original charger, other mobile phone chargers can be used as an emergency. The specific steps to use when charging the lithium-ion battery charger are very simple, just plug it in according to the ordinary battery charger and check the power supply instructions. To charge a lithium-ion battery, the voltage must match the voltage of the lithium-ion battery, and the current must match the ampere-hour capacity of the lithium-ion battery; in addition, the charger has a charging protection function to prevent overcharge, failure, etc. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
