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.
This primary lithium cell must be stored in a cool, dry environment between -40°C and 55°C to prevent thermal degradation. Charging is strictly prohibited as it may cause thermal runaway, fire, or explosion.
- Storage Temperature Range: Maintain storage temperature within -40°C to 55°C to preserve electrochemical stability.
- Charge Prohibition: Never attempt to recharge this non-rechargeable cell, as it may lead to catastrophic thermal runaway.
- Short Circuit Prevention: Avoid external short circuits by insulating terminals and storing cells in non-conductive packaging.
- Mechanical Integrity: Inspect for denting, swelling, or punctures before use to mitigate risk of internal short circuit.
- Disposal Protocol: Discharge fully through a resistive load before disposal per local hazardous waste regulations.
This cell delivers high current and requires controlled deployment to avoid thermal or electrical hazards. Follow these steps to safely integrate the cell into a device or test setup.
Required Equipment: Insulated gloves, Digital multimeter, Non-conductive work surface, Cell holder with fused leads
- Inspect cell condition
Visually examine the cell casing for dents, swelling, or corrosion before handling. - Verify open-circuit voltage
Measure voltage across terminals using a multimeter to confirm it lies within 2.3V to 4.3V. - Mount cell securely
Place the cell into a non-conductive holder or enclosure with fused output leads. - Connect resistive load
Attach a load rated for at least 45A continuous and monitor for excessive heat generation. - Monitor during discharge
Check cell temperature periodically and disconnect immediately if surface exceeds 60°C.
What capacity retention can be expected from the 8540140-15 cell at -40°C compared to room temperature, and what trade-off in voltage range is required?
The 8540140-15 maintains over 70% capacity retention at -40°C. To achieve this extreme low-temperature performance, the operating voltage range shifts to 2.3V–4.3V (versus nominal 3.8V at 25°C). This voltage trade-off is necessary to sustain discharge capability down to -40°C while delivering the full 15Ah capacity.
What are the critical integration constraints for using the 8540140-15 primary cell in a series or parallel pack assembly?
The 8540140-15 is a primary (non-rechargeable) cell, meaning charging is strictly prohibited to avoid thermal runaway. For pack assembly, customization options include spot-welded nickel tabs and specialized insulation wrapping. Engineering support is provided for integration into cryo-stabilized battery boxes to maintain safe operation under extreme conditions.
What safety tests has the 8540140-15 passed, and what handling precautions are required for storage and transport?
The cell passed 1.5m concrete fall tests, low-pressure (vacuum) tests, and external short-circuit protocols with zero fire or explosion risk. Despite its robust safety validation, it is a primary cell and must never be charged. Storage and transport should follow standard lithium primary cell precautions; the operating temperature range is -40°C to 55°C.
The 8540140-15 is a 15Ah primary lithium cell optimized for extreme low-temperature discharge down to -40°C with 70% capacity retention, supporting 3C continuous and 5C pulse discharge. Its non-rechargeable chemistry and 55°C upper temperature limit require careful system integration for dedicated single-use applications.
Positive
- Ultra-low temperature capability: Maintains over 70% capacity retention at -40°C, enabling reliable power for polar, high-altitude, and aerospace instrumentation in sub-zero environments.
- High discharge rate with low internal resistance: Supports 3C continuous (45A) and 5C pulse (75A) discharge while internal resistance remains below 3 mOhm, minimizing thermal loss during heavy-duty operation.
Trade-offs
- Non-rechargeable primary cell: This cell is single-use only; charging is strictly prohibited and may cause thermal runaway. It must be replaced after depletion, increasing long-term operational cost.
- Limited upper operating temperature: Discharge capability is specified only up to 55°C, restricting use in applications that may experience sustained temperatures above this threshold without thermal management.
