1.5v Dry Battery.Lithium ion batteries for mobile phones

source:Industry News release time:2023-12-27 Hits:     Popular:AG11 battery

  

  The lithium battery for mobile phones mainly consists of a plastic case upper and lower cover, a lithium battery cell, a protective circuit board (PCB), and a recoverable fuse (polyswitch). Some manufacturers also install 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. Generally, a branded regular seat charger is sufficient, priced between 15-20 yuan, eliminating the limitation of relying on a mobile phone for direct charging.

  (1) Lithium battery cells: provide a rechargeable power supply.

  (2) Protect the circuit board (PCB): prevent battery overcharge, over discharge, and short circuit.

  (3) Restorable fuse (PTC): The positive thermistor provides high-temperature protection and serves as a secondary protection for circuit board failure.

  (4) Restorable fuse (NTC): a negative thermistor that senses the internal temperature of the battery and provides low-temperature protection.

  (5) Identify resistance: Identify that non original batteries cannot be used.

  (6) Automatic emergency power reserve.
