14500 battery

The "14500" battery is a type of lithium-ion (Li-ion) or lithium-ion polymer (LiPo) rechargeable battery that is physically similar in size to an AA (LR6) battery but with a higher voltage and capacity. The "14500" designation refers to the battery's dimensions:

    14 mm in diameter
    50 mm in length (excluding the positive terminal button)

Here are some key characteristics and details about 14500 batteries:
Characteristics:

    Nominal Voltage: 3.7 volts, which is higher than the 1.5 volts of a standard alkaline AA battery.
    Capacity: Typically ranges from 500mAh to 1200mAh or more, depending on the specific model and brand.
    Chemistry: Lithium-ion or lithium-ion polymer.
    Charge Cycles: Can be recharged hundreds of times, depending on the quality and usage conditions.
    Self-discharge Rate: Lower than NiMH batteries, but still loses charge over time when not in use.

Applications:

    Flashlights: Many LED flashlights are designed to accept 14500 batteries.
    Portable Electronics: Some small electronic devices, such as portable audio players, can use 14500 batteries.
    RC Models: Small radio-controlled models and drones may use 14500 batteries.
    Other Portable Devices: Various small devices that require a higher voltage than what an AA battery provides.

Charging:

    Charging: Requires a charger specifically designed for lithium-ion batteries to avoid overcharging, which can damage the battery.
    Discharging: It's recommended to discharge 14500 batteries fully before recharging to maintain optimal performance, although modern batteries are less susceptible to memory effects.

Safety:

    Handling: 14500 batteries should be handled carefully to avoid short circuits or exposure to extreme temperatures.
    Disposal: Dispose of 14500 batteries according to local regulations, as they contain hazardous materials.
