Core Features
1. Ultra-Wide Temperature Operation
The 11.5V 6400mAh Low Lithium Battery operates in charging temperatures as low as -40°C and discharging temperatures from -40°C to 70°C. This industry-leading tolerance ensures consistent performance in polar expeditions, high-altitude telecom sites, or desert-based infrastructure—critical for systems that cannot fail in extreme cold or heat.
2. High Capacity Retention in Harsh Cold
At -40°C, this battery maintains a capacity retention rate of ≥70%, ensuring emergency backup and communication devices retain enough power to function during critical moments in frigid environments.
3. Exceptional Cycle Life
With a lifespan of ≥10,000 cycles (under 0.2C charge/discharge conditions), the 11.5V 6400mAh Low Lithium Battery outlasts traditional chemistries. This reduces replacement frequency and total cost of ownership for long-term deployments.
4. Robust Safety & Performance
Equipped with protection against overcurrent (up to 10A), short circuits, and voltage anomalies, the battery safeguards critical equipment. It also supports up to 6C charge/discharge at room temperature for rapid energy transfer when conditions allow.
Application Scenarios
The 11.5V 6400mAh Low Lithium Battery powers:
- Emergency Backup Systems: Delivering reliable 11.5V power for medical devices, industrial controls, or critical infrastructure during outages—even in -40°C conditions.
- Outdoor Communication Equipment: Supporting telecom relays, satellite modems, or IoT sensors in extreme climates (e.g., arctic research stations, desert telecom towers).
- Defense & Aerospace Tools: Enabling mission-critical gear in military or aerospace applications where temperature extremes and reliability are non-negotiable.
