Accessories & Customization
Safety Warning: This is a PRIMARY (Non-rechargeable) cell. Charging is strictly prohibited and may cause thermal runaway.
Customization Options: Available with custom spot-welded nickel tabs, specialized insulation wrapping, and series/parallel pack assembly for specific voltage requirements. Engineering support is provided for integration into cryo-stabilized battery boxes.
Charging this primary cell is strictly prohibited due to risk of thermal runaway. The cell must be discharged only within the temperature range of -40°C to 55°C and must not exceed the specified discharge current limits.
- Charging Prohibition: Charging this primary cell is strictly prohibited and may cause thermal runaway.
- Discharge Temperature Range: The cell must be discharged only within the temperature range of -40°C to 55°C.
- Discharge Current Limits: Continuous discharge must not exceed 3C (45A) and pulse discharge must not exceed 5C (75A) for 10 seconds.
How does the 8540140-15 primary lithium cell maintain capacity at -40°C while supporting high discharge rates?
The cell uses a specialized electrolyte chemistry that enables over 70% capacity retention at -40°C and supports 3C continuous (45A) and 5C pulse (75A for 10s) discharge across the full -40°C to 25°C range. Its internal resistance below 3 mOhm minimizes heat generation, allowing efficient high-power operation even under extreme cold.
What are the critical design considerations when integrating this primary lithium cell into a cryo-stabilized battery pack?
As a non-rechargeable primary cell, charging is strictly prohibited and may cause thermal runaway. For pack integration, the manufacturer offers custom spot-welded nickel tabs, specialized insulation wrapping, and series/parallel assembly options. Engineering support is available for integration into cryo-stabilized battery boxes to meet specific voltage and environmental requirements.
What safety certifications and mechanical tests has this cell passed to ensure reliability in extreme environments?
The cell has passed 1.5m concrete fall tests, low-pressure (vacuum) tests, and external short-circuit protocols with zero fire or explosion risk. This validated reliability, combined with its -40°C to 55°C operating temperature range and <3 mOhm internal resistance, makes it suitable for mission-critical applications in polar research, aerospace, and military hardware.
The 8540140-15 primary lithium cell delivers 15Ah capacity with reliable discharge down to -40°C and high pulse current up to 75A, but is constrained to single-use applications as it is non-rechargeable and charging is prohibited.
Positive
- Ultra-Low Temperature Performance: The cell maintains over 70% capacity retention at -40°C, enabling reliable operation in extreme cold environments such as polar research and high-altitude aerospace.
- High Discharge Capability: With 3C continuous and 5C pulse discharge (up to 75A), the cell supports high-intensity equipment requiring heavy-duty power delivery.
Trade-offs
- Non-Rechargeable Design: As a primary lithium cell, it is not rechargeable; charging is strictly prohibited to prevent thermal runaway, limiting use to single-discharge applications.
- Discharge-Only Temperature Range: The specified operating temperature range (-40°C to 55°C) applies only to discharge capability, and no charging is possible, restricting its use to one-time power delivery scenarios.
