Ultra Low Temp Li-ion Battery
Ultra Low Temperature Lithium-Ion Batteries are advanced energy storage solutions specifically engineered to operate in extreme cold environments, making them ideal for applications requiring reliable power in sub-zero conditions. Unlike standard lithium batteries, which typically cease functioning below -20°C (-4°F), these specialized batteries maintain functionality even at ultra-low temperatures as frigid as -40°C (-40°F), ensuring uninterrupted performance in harsh climates such as polar regions, high-altitude environments, or cold-chain logistics.
Extreme-Temperature Battery: -40°C to 80°C Resilience
Deliver consistent power in polar winters and desert heat with innovative thermal management technology.
Where Can -40°C Batteries Power Your Innovations?
From polar drones to lunar rovers, discover industries relying on freeze-proof lithium batteries.
How Do These Batteries Beat Extreme Cold?
Built for the toughest cold, this tech keeps drones flying in polar storms and protects life-saving vaccines in deep freeze.

- Voltage Stability: ±2% fluctuation @-40°C
- Efficiency Loss: <15% after 500 cycles
- Operating Range: -40°C to 80°C
- Storage Range: -55°C to 85°C (MIL-STD compliant)
- Heating Rate: 5°C/min (on demand)
- Cooling Recovery: 30min to 25°C
Custom Ultra-Low Temp Battery Solutions
What temperature range does my device require?
For ultra-low temp applications (e.g., Arctic sensors, cold-chain logistics), specify your operating range (e.g., -40°C to 60°C). Our CryoCore™ batteries guarantee stable discharge at -40°C with optional heating modules for rapid cold startups.
What voltage and capacity do I need for extended runtime in extreme cold?
Provide device voltage (3V-72V) and desired runtime hours. Note: Capacity reduces by ~20% at -40°C – we compensate with higher-density cells (up to 320Wh/kg).
Can you design batteries for tight spaces or irregular shapes?
Yes! Share your device’s battery compartment dimensions (LxWxH) and shape (e.g., curved, ultra-thin <3mm). We use flexible pouch cells or modular stacking for space-critical applications.
How often will the battery recharge in sub-zero conditions?
Frequent charging in cold environments accelerates aging. We optimize cycle life (5,000+ cycles at -40°C) with low-temperature LiFePO4 or NMC chemistries.
Will humidity or movement affect performance?
Our IP68-rated packs resist moisture (humidity ≤95%) and vibration (20G/10Hz). For outdoor/mobile use (e.g., drones), we reinforce with shockproof casings.
What’s the minimum order quantity (MOQ) for custom designs?
Prototype MOQ: 50 units. Bulk orders (1,000+ units) qualify for discounted pricing and 3-week lead times.
