Why It Excels in Cold Environments
-
Reliable -40℃ 1C Discharge“This 18650 low temperature cell retains 70% capacity at -40℃ with 1C discharge—powering Arctic drones for 30+ minutes. Standard 18650s often fail below -20℃, making them useless in extreme cold.”
-
0℃ Charging Capability“Charges in 0℃ freezing conditions (where standard 18650s—needing ≥5℃—can’t recharge). Critical for cold-chain sensors to stay online in sub-zero storage/transport.”
-
2.2A Symmetric Charge & Discharge“Delivers 2.2A for both charging and discharging: Refuels a 2200mAh cell in 2 hours (perfect for military gear like night-vision goggles), and supplies 2.2A to run 8W devices at -40℃ without voltage sag.”
-
Puncture & Impact Safety“Passes puncture and shooting tests—safe for heated vests or high-risk cold zones (e.g., gas pipelines). This 18650 cell is built to withstand danger while powering critical gear.”
Application Scenarios
- Arctic Exploration & Military
- Polar Research: Powers ice-core drills and -40℃ drones; a 2200mAh cell supports 12+ hours of data collection in extreme cold.
- Military Gear: 2.2A fast charging refuels night-vision goggles in 2 hours, with 70% capacity at -30℃ for mission readiness.
-
Cold-Chain Logistics“Cold storage sensors rely on 70% capacity at -40℃ (1C discharge) to run 12+ hours—ensuring vaccine integrity during -30℃ transport with these low temperature 18650 batteries.”
-
Outdoor & Winter Sports“Powers smart goggles, heated vests, etc. Recharges in 2 hours between ski runs (even in -10℃ resorts) thanks to this specialized 18650 low-temp cell.”
Customization Services
We offer customization for 18650 low temperature cells:
- Capacity Scaling: 1800mAh → 2600mAh (parallel clusters for longer runtime).
- Discharge Rate: Upgrade to 1.5C (like LT-1800 for high power).
- Temperature Tuning: -40℃ → -35℃ (extended cycle life, e.g., LT-2600).
- BMS Integration: Smart charge control for -40℃ environments to prevent overcharge.
