Main Features
  • Ultra-Thin & Compact Form Factor: With dimensions of 5mm (thickness) * 20mm (width) * 30mm (length) and a typical weight of 4-6g, it features an ultra-slim, miniaturized design--perfect for devices with strict space constraints.
  • Balanced Electrical Performance: Boasts a nominal voltage of 3.7V (working voltage range: 3.0V-4.2V) and 250mAh capacity (0.925Wh energy), striking a balance between runtime and size.
  • Reliable Safety Protection: Adopts a soft-package lithium battery structure with a built-in protection IC. It effectively prevents overcharge, over-discharge, short circuits, and overcurrent.
  • Durable Cycle Life: Supports 300-500 charge-discharge cycles (under standard conditions). After 300 cycles, it retains over 80% of its initial capacity.
  • Low Self-Discharge Rate: Loses only 5%-8% of capacity per month at room temperature, making it suitable for devices that require occasional use or long standby.
  • Wide Environmental Adaptability: Operates stably in a temperature range of -10℃-60℃ (discharge) and 0℃-45℃ (charge).
Main Applications
Mini Wearable Devices:
  • Children's basic smartwatches
  • Mini health monitors (e.g., portable oximeter, heart rate trackers)
  • Smart jewelry (e.g., mini smart bracelets, smart rings)
IoT Micro Sensors:
  • Smart home mini sensors (e.g., door/window contact sensors)
  • Industrial mini sensors (e.g., micro pressure sensors)
  • Agricultural micro sensors (e.g., mini soil moisture sensors)
Small Consumer Electronics:
  • Wireless earbud charging cases
  • Mini digital devices (e.g., portable mini voice recorders)
  • Portable mini LED lights
Medical & Emergency Gadgets:
  • Fingertip mini blood glucose meters
  • Emergency mini devices (e.g., portable mini alarms)
Mini Toys & Models:
  • Micro remote-controlled (RC) toys
  • Electronic educational toys
