Does high current charging affect the battery?丨MSH

If the current fluctuates within the allowable charging current of the battery, it will have no effect. For example, lead-acid batteries and nickel-metal hydride batteries must be charged by pulse. Generally, the lithium battery is 0.2C, that is, a 1000MAH battery, and the charging current fluctuates between 0MA and 200MA.
Note when charging:

1. Don't answer the phone while charging
Under normal circumstances, the insulation between the parts with dangerous voltage and the accessible conductive parts is broken down or the contact current is too large, it is easy to cause electric shock to the user. Especially for some smartphone users, "charging while playing" has become commonplace, and they should be more careful. In addition, poor quality cell phone chargers are also prone to catch fire.

2. It is best to use direct charging
The original mobile phone charger has an overvoltage protection circuit, and is equipped with a rectifier transformer device, which can convert high voltage into low voltage, and convert direct current into alternating current. Most of the universal chargers are produced by informal manufacturers without protective coils, which are easy to cause the voltage or current to be too high and unstable. Excessive voltage is easy to charge the battery, and sometimes it can cause dangerous explosion, and the mobile phone is easy to burn out.

3. Choose quality products
When buying mobile phone chargers and batteries, you must choose products that are qualified by regular manufacturers. Fire experts pointed out that a good charger has an overheating self-protection circuit inside. When its internal temperature reaches a certain value, it will automatically disconnect the power supply, which plays a certain degree of protection.

4. Try to charge when someone is watching
The mobile phone battery should be charged when someone is present, so that the abnormal situation can be handled in time. During charging, you should pay attention to the temperature of the charger and whether there is a burnt smell. If the temperature is too high, it is obviously hot to the hand or there is a burnt smell, etc., stop charging first, check the cause and take necessary measures before charging.

5. Do not cover anything while charging the phone
When charging, the voltage of the mobile phone is higher than the standby state. If an unqualified battery or charger is used, and the charging environment is poor, such as high temperature and humidity, accidents may occur.

6. Unplug the power plug when not in use
After charging, remember to unplug the power plug, which can effectively prevent the power bus from causing fire.
