AA Battery 1.2V 2100mAh WESTINGHOUSE (2pcs)

Specifications

1. Type:
   • Nickel-Metal Hydride (NiMH): Most AA rechargeable batteries, including those rated at 1.2V, typically use NiMH chemistry. This type of battery is known for its higher capacity and lower self-discharge rates compared to older NiCd (Nickel-Cadmium) batteries.
2. Voltage:
   • Nominal Voltage: 1.2 volts. This is standard for NiMH batteries, which is lower than the 1.5V typically provided by alkaline AA batteries but remains suitable for most applications.
3. Capacity:
   • Capacity Rating: 2100mAh (milliamp-hours). This indicates how much charge the battery can hold, representing its capacity to supply a given load over time. For example, a 2100mAh battery can theoretically deliver 2100 milliamperes for one hour, or 210 milliamperes for ten hours.
4. Size:
   • AA Format: These batteries have standard AA dimensions (about 50.5 mm in length and 14.5 mm in diameter) and can be used interchangeably with any battery-operated device that accepts AA batteries.
5. Brand:
   • Westinghouse: A well-known brand that signifies reliability and quality in power solutions.

Advantages

• Rechargeable: Unlike disposable batteries, NiMH batteries can be recharged after use, making them more environmentally friendly and cost-effective in the long run.
• Low Self-Discharge Rate: NiMH batteries have improved self-discharge rates compared to older technologies, meaning they hold their charge longer when not in use.
• Versatility: Can be used in various applications, including household devices, cameras, remote controls, toys, and more.

Applications

• Consumer Electronics: Commonly used in devices like digital cameras, remote controls, flashlights, and game controllers.
• Toys: Ideal for high-drain toys that require reliable and consistent power.
• Household Devices: Suitable for devices like wireless mice, keyboards, and other electronics that benefit from rechargeable batteries.
• Emergency Preparedness: Useful in flashlights and radios, where having a rechargeable battery can be beneficial during power outages.

Charging

• Compatibility: Use a charger specifically designed for NiMH batteries to ensure safety and battery longevity. Avoid using chargers meant for alkaline batteries.
• Charging Time: The time to fully charge these batteries varies based on the charger used but generally ranges from 2 to 5 hours.

Important Considerations

• Charging Cycles: NiMH batteries can typically withstand hundreds of charge/discharge cycles, but their lifespan may diminish with each cycle.
• Proper Storage: Store in a cool, dry environment and avoid exposing to extreme temperatures, which can affect performance and lifespan.
• Device Compatibility: While NiMH batteries can often replace disposable alkaline batteries, consider device specifications, especially with devices designed primarily for 1.5V alkaline batteries
