Voltage Comparison: 3.7V vs 3.8V Lithium Polymer Batteries
Nominal Voltage vs Charging Voltage

3.7V Standard Voltage Battery: Nominal voltage is 3.7V, charging cut-off voltage is 4.2V.

3.8V High Voltage Battery: Nominal voltage is 3.8V, charging cut-off voltage is 4.35V.

Energy Density

High voltage batteries provide higher energy output within the same volume. For cells of the same capacity (e.g., 2000mAh):

  • 3.7V system energy ≈ 7.4Wh
  • 3.85V system energy ≈ 7.7Wh, with volumetric energy density increase of approximately 15%
  • High-voltage systems achieve higher plateau voltages by increasing nickel content in cathode material
Cycle Life and Degradation

High-voltage batteries have shorter cycle life due to higher operating voltage. High-voltage batteries are suitable for scenarios with high battery life requirements but less stringent lifespan requirements, while standard-voltage batteries are better for devices requiring long-term use.

Applicable Scenarios

3.7V Standard-Voltage Batteries: Widely used in portable devices such as Bluetooth headsets, dashcams, and headlamps; mature technology, high safety, and low cost.

3.8V High-Voltage Batteries: Primarily used in devices with higher battery life requirements, such as high-end mobile phones, IoT terminals, and medical equipment; require circuits supporting 4.35V charging.

Applications
  • Smart Wearable Devices: smart bracelets, smart rings, hearing aids
  • Beauty & Personal Care: electric beauty devices, radio frequency devices, electric toothbrushes
  • Consumer Electronics: Bluetooth headsets, VR glasses, remote controls, wireless microphones
  • Home & Tools: LED lights, mosquito repellent lamps, aromatherapy diffusers, detectors
  • Adult Products: compliant vibrators and sex toys
  • Industrial Equipment: GPS trackers, scanning pens, electronic locks
3.8V Lithium Polymer Battery Advantages
  • Higher Energy Density: Stores more energy in the same volume or weight, increasing battery life by 15%-25%
  • Higher Discharge Platform: Nominal voltage up to 3.8V (3.85V for some models), providing more stable high-voltage output for voltage-sensitive high-performance electronic devices
  • Superior Energy Conversion Efficiency: Reduces DC/DC conversion losses and supports LDO driving of components, reducing electromagnetic interference and improving call quality
  • Slim and Customizable: Can be made into ultra-thin (minimum 0.5mm) batteries of any shape, suitable for various portable electronic products
