  The lithium battery of the mobile phone is mainly composed of plastic shells, lithium batteries, protective circuit boards (PCB) and recoverable fuse (Polyswitch). Some manufacturers are also equipped with elements such as NTC, identification resistance, vibration motor or charging circuit. Lithium batteries are durable products, so they are not delicate. Everyone can treat it calmly and do not need to be equipped with expensive original charges. Generally, there are ordinary brand charges. The price is 15-20 yuan, which saves the restrictions on the mobile phone that needs to be rely on mobile phones.

  (1) Lithium cells: Provide a power -can be used to charge the power supply.

  (2) Protecting the line board (PCB): Prevent the battery from overcoming the short circuit.

  (3) Refining fuse (PTC): Positive thermistor resistance to high -temperature protection is also a dual protection after protecting the lineboard.

  (4) Refining fuse (NTC): negative thermal resistance, and the internal temperature of the induced battery plays a low temperature protection role.

  (5) Identification resistance: Identification of the original battery non -original battery cannot be used.

  (6) Emergency power supply.
