Why Wide Temperature -20°C to +60°C?
| Environment | Standard Battery (0~45°C) | ASOL 903659 (-20~60°C) |
|---|---|---|
| Outdoor Security Camera (Winter) | ❌ Fails below 0°C | ✅ Works at -20°C |
| Dashcam in Parked Car (Summer) | ❌ Fails above 45°C | ✅ Works at +60°C |
| Outdoor GPS Tracker (Winter) | ❌ Fails below 0°C | ✅ Works at -20°C |
| Smart Video Doorbell (All Season) | ❌ Limited to mild climates | ✅ -20°C to +60°C |
Standard consumer LiPo batteries are rated for 0°C to +45°C charging and 0°C to +60°C discharging. The 903659’s -20°C lower limit extends deployment into outdoor winter security monitoring, cold-weather GPS tracking, and year-round smart home installations.
