Li-ion Rechargeable AA Battery 3.7V 400mAh

The Li-ion AA 3.7V Actual Capacity 400mAh Rechargeable Battery is a high-energy-density power source that delivers stable voltage and long-lasting performance. With a lightweight design, low self-discharge rate, and high efficiency, it is ideal for high-drain applications. Unlike traditional Ni-Cd or Ni-MH batteries, Li-ion cells provide a higher voltage and better energy retention, making them perfect for modern electronic devices.

Features:

• Can be recharged multiple times, offering a more sustainable and cost-effective alternative to disposable batteries.
• Provides more power per charge compared to traditional AA rechargeable batteries, making it suitable for high-power applications.
• 3.7V nominal, which is higher than typical AA batteries (1.2V or 1.5V), providing a more powerful output.
• Actual Capacity 400mAh, which allows for longer usage in devices like cameras, flashlights, and other portable electronics.
• Li-ion batteries typically last for up to 500-1000 charge cycles, depending on usage and charging conditions.
• Ideal for portable devices where size and weight are crucial.
• Many Li-ion batteries come with integrated protection to prevent overcharging, over-discharging, and short circuits.
