BHL114258-2.4Ah Low-Temperature Lithium-Ion Cell | Features & Applications
Ⅰ. Core Product Advantages
Ⅰ. Stable Discharge at -20℃, Adaptable to All-Season Conditions
Charging temperature: 0℃~40℃; Discharge temperature: -20℃~55℃.
The cell retains ≥95% capacity at 55℃, delivers 100% rated capacity at room temperature, and maintains 95% capacity at 0℃ with a low-temperature cut-off voltage of 2.3V at -20℃. For small-scale equipment operating in cold northern regions and cold storage environments, no heating accessories are required. It simplifies thermal control structures and effectively reduces overall equipment design costs.
2. Ultra-Thin & Compact 2.4Ah Design with Stable 1C Continuous Discharge
Featuring an ultra-thin 11mm aluminum-plastic pouch structure, the compact cell occupies minimal internal equipment space. The 2.4Ah capacity balances portability and endurance, supporting steady 1C continuous discharge with negligible voltage drop. The surface temperature is controlled within 70℃ during charge and discharge cycles, resisting accelerated aging under frequent start-stop operation and fully meeting the continuous working demands of miniature devices.
3. 600 Stable Cycles & Low Self-Discharge for Easy Long-Term Storage
It achieves up to 600 standard charge-discharge cycles while retaining over 80% rated capacity at the end of the cycle life. After 30 days of full-charge static storage at room temperature, the cell maintains ≥85% residual capacity with extremely low self-discharge loss. For long-term storage, a 10%~35% state of charge is recommended. Stored in a dry environment of -20℃~45℃, it only requires annual supplemental charging, perfectly suited for unattended long-term operation of miniature field monitoring equipment.
4. Full-Range Strict Safety Tests for High Reliability in Miniature Devices
The cell has passed comprehensive safety tests including overcharge, deep overdischarge, external short circuit, 135℃ thermal shock, high-low temperature alternating cycle, three-axis swept vibration and six-direction drop tests, with zero fire, liquid leakage or explosion throughout all tests. The flexible aluminum-plastic shell resists minor extrusion. Matched with a protective board, it provides triple protection against overcharge, overdischarge and overcurrent, fully complying with safety standards for handheld and wearable devices.
5. Standardized Mini Pouch Cell for Convenient Small-Batch Assembly
With a standardized ultra-thin compact size, cells from the same batch feature voltage difference ≤20mV and internal resistance difference ≤6mΩ, ensuring internal PACK temperature deviation ≤5℃. Only resistance welding and laser welding are permitted; tin welding is prohibited. Flexible series and parallel combinations eliminate the need for custom metal shell molds, significantly improving production efficiency for small-batch miniature instruments and wearable devices.
Ⅱ. Industry Application Scenarios
