11 | Operating temperature | Charging: 0 °C ~45 °C Discharging:0 °C ~45 °C |
12 | Storage temperature | -10°C~ +45 °C |
13 | Dimension | Length:35±0.5mm (not including tabs) Width:20±0.5mm Thickness:5±0.2mm |
14 | Drop Test | The cell is to be dropped from a height of meter twice onto concrete ground. No fire, no leakage |
15 | cycle time | ≥800times |
Advantages:
Safety performance: Built-in protection board, supports short circuit protection, overcharge protection, over-discharge protection, and overcurrent protection to avoid battery damage or safety hazards.
Wide temperature adaptability: Can work stably in an environment of -20°C to 60°C, meeting the needs of various scenarios.
High charging efficiency: Supports standard 0.5C charging (constant current to 4.25V and then constant voltage to 4.2V), compatible with fast charging (1C current).
Application:
Consumer electronic equipment: Bluetooth headsets, Bluetooth speakers, MP3/MP4 players, reading pens, voice recorders and other small portable devices.
Medical and wearable equipment: cervical massagers, smart bracelets, blood glucose meters and other medical equipment that require lightweight power support.
Outdoor and industrial equipment: Walkie-talkies, GPS locators, handheld electric drills and other outdoor tools that require high temperature resistance.
