The lithium battery for mobile phones mainly consists of a plastic cover, a lithium battery cell, a protective circuit board (PCB), and a recoverable fuse (polyswitch). Some manufacturers also configure components such as NTC, identification resistors, vibration motors, or charging circuits. Lithium batteries are durable goods, so they are not delicate. Everyone can treat them calmly and there is no need to equip them with expensive original seat chargers. Function (1) Lithium battery: Provides a rechargeable power supply. (2) Protection circuit board (PCB): prevent battery overcharging, discharging, and short circuit. (3) Recoverable Fuses (PTC): Positive thermistors provide high-temperature protection while also providing secondary protection after circuit board failure. (4) Recoverable fuse (NTC): Negative thermistor, which senses the internal temperature of the battery and provides low-temperature protection. (5) Identify resistance: Identify that the original battery cannot be used without the original battery. (6) Automatically reserve emergency power. In addition, due to the characteristics of lithium batteries, there is no need for discharge and overcharging operations. The lifespan of a battery completely depends on the effective charging time. That is to say, even if you only use half of it to start charging, it will not affect the battery life
