Usage & Maintenance Guidelines
For use only with devices marked "3.7V Small Lithium Polymer Battery" (e.g., smart bracelets, micro sensors). Do not use with other battery specifications to prevent voltage mismatch.
Important: Inspect battery every 1-2 months. Discontinue use if you notice bulging or leakage (sticky white powder). For long-term storage, maintain charge at 3.7-3.8V (50%-60% capacity).
Storage Recommendations
- Store at 10-25°C (optimal 20°C) with humidity <60%
- Keep away from humid environments and heat sources
- Use insulated containers away from metal objects
- Wrap terminals when storing multiple batteries
Transportation Guidelines
- Wrap terminals with insulating tape or caps
- Use bubble wrap or foam bags for protection
- For bulk transport, use anti-static packaging
- Maintain temperature between 10-30°C during transport
Primary Applications
- Portable electronics: Bluetooth headsets, electronic scales, toys
- Consumer electronics: Beauty devices, education devices
- Energy storage: Dashcams, Bluetooth speakers
- Small drones (for short-range missions)
