Can the chipless lithium battery charging method be used with a universal charger? Experts give me a

First of all, the universal charger for mobile phones can charge 18650 batteries. The voltage of a mobile phone battery and a laptop battery is the same, both 3.7V. difference is that the cell phone battery contains a protective plate. Your unique battery 18650 battery does not have a protection plate, so you need to consider the overrun problem. Check your universal charger. The output voltage should not exceed 4.3 V. There is also the charging current if your universal charger is. 200 mah, only 18650. The rated capacity is 2200 mah and the charging time should be limited to 12 hours. The calculation formula is: battery capacity/charging current + 1 hour. In use, without a protection board, the lithium battery voltage cannot be lower than 2.5V. Otherwise, the battery life will be greatly reduced.
