Physical and Application Profile

This battery is typically housed in a ‌prismatic or pouch cell‌ design, emphasizing ‌minimal thickness and light weight‌—often under ‌20g‌. It is widely integrated into:

  • Wearable devices‌: smartwatches, fitness trackers, hearables
  • Miniature drones and toy-grade RC models
  • Bluetooth accessories‌: earbuds, remotes, mini speakers
  • IoT sensors and medical wearables‌: temperature monitors, patch devices

Its compact form factor requires precise fitment, so users must verify ‌physical dimensions, connector type (e.g., JST-PH 2.0mm), and polarity‌ before replacement or integration.

Charging and Safety Considerations

To ensure safety and longevity:

  • Use a ‌constant current/constant voltage (CC/CV) charger‌ set to ‌3.7V (4.2V full charge)
  • Charge at ‌0.5C–1C rate (215mA–430mA)‌ to avoid overheating
  • Store at ‌3.7–3.8V (partial charge)‌ in a cool, dry environment
  • Avoid over-discharge below ‌3.0V‌ to prevent cell damage

The battery may include ‌built-in protection circuits‌ against overcharge and short circuits, but external PCM integration is recommended in custom applications.
