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 kinds of lithium-ion batteries, and the battery performance and battery protection plate parameters may be different. Therefore, lithium-ion batteries are not the same as ordinary batteries. They have universal battery chargers. Generally speaking, lithium-ion batteries are supplied with special chargers. In order to protect the lithium-ion battery, a special charger is required.

The voltage and current of ordinary chargers are too high to meet the charging conditions of lithium ion batteries. The end of charge voltage of 11V lithium-ion battery should be 12.5V, and the charging current range is 0.1 to 1.5 times of the capacity of the lithium-ion battery. In order to prolong the battery life, 0.1 times is usually better, and 0.5 times can be used for rapid charging.

The charging control of lithium ion battery is to charge according to the constant current first, and then when the battery voltage rises to 4.2V, the voltage will not rise again. The charger will detect the current, and if the current is less than a certain value, the charging will end. Lithium battery is sensitive to overcharge, so the protection circuit is complex. The maximum charging rated voltage of a single 3.6V battery is 4.2V, and the upper limit of allowable error is not more than 1%.

If the chargers of different mobile phones have the same charging specifications, the size of the charging port is also suitable for mixed use. Chargers of the same specification will not damage the battery, but if the specifications are different, such as high voltage or power, it is likely to damage the cell phone battery. It is recommended to use the original charger. Other mobile phone chargers can be used for emergency.

The specific steps for charging the lithium ion battery charger are very simple. Just plug it in according to the general battery charger and check the power indication. The charging of the lithium ion battery shall meet the requirements of matching the voltage with the lithium ion battery, and matching the current with the ampere hour capacity of the lithium ion battery; In addition, the charger has a charging protection function to prevent overcharge, failure, etc.
