1.2V Ni-MH battery

1.2V Ni-MH (Nickel-Metal Hydride) batteries are rechargeable batteries commonly used in a variety of portable electronic devices. They are known for their high energy density and low environmental impact compared to other rechargeable battery technologies. Here's some more detailed information about 1.2V Ni-MH batteries:
Characteristics:

    Nominal Voltage: Each Ni-MH cell has a nominal voltage of 1.2 volts.
    Capacity: Ni-MH batteries come in various capacities, typically ranging from 500mAh to 3000mAh or more, depending on the size and intended use.
    Self-discharge Rate: Ni-MH batteries have a moderate self-discharge rate, losing about 1% to 3% of their charge per day when not in use.
    Charge Cycles: Ni-MH batteries can be recharged hundreds to thousands of times, depending on the quality of the battery and how it is used and maintained.
    Environmental Impact: Ni-MH batteries are considered more environmentally friendly than NiCd (Nickel-Cadmium) batteries because they do not contain toxic heavy metals like cadmium.

Common Sizes:

Ni-MH batteries are available in standard sizes, including:

    AA (LR6): Widely used in portable electronics, such as digital cameras and remote controls.
    AAA (LR03): Commonly used in smaller devices like wireless mouse and keyboards.
    C (LR14): Often found in medium-power devices like flashlights.
    D (LR20): Used in high-power devices such as large flashlights and toys.
    9V (6F22): Used in smoke detectors and other electronic devices that require a higher voltage.

Applications:

    Consumer Electronics: Digital cameras, remote controls, toys, and portable audio players.
    Portable Devices: Cordless phones, portable gaming consoles, and wireless keyboards/mice.
    Professional Tools: Power tools, flashlights, and emergency lighting.
    Hybrid Vehicles: Some older hybrid vehicles used Ni-MH batteries for their propulsion systems.

Charging and Discharging:

    Charging: Ni-MH batteries should be charged using chargers specifically designed for Ni-MH batteries to avoid overcharging, which can damage the battery.
    Discharging: It's recommended to discharge Ni-MH batteries fully before recharging to maintain optimal performance, although modern Ni-MH batteries are less susceptible to memory effects.

Safety:

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