How to Prevent Lithium-Ion Battery Fires and Explosions
What Are the Key Specifications of the Tenergy SubC 2200mAh NiCd Battery?
The Tenergy SubC NiCd battery features a 2200mAh capacity, 1.2V nominal voltage, and a rapid-charge design. It operates between -20°C to 60°C, supports up to 1,500 charge cycles, and has a low self-discharge rate (15-20% monthly). Its SubC size (22.2mm diameter, 42.9mm height) ensures compatibility with devices requiring compact, high-output power sources.
| Parameter | Value |
|---|---|
| Nominal Voltage | 1.2V |
| Peak Discharge Current | 30A |
| Weight | 72g |
| Cycle Life | 1,000+ |
How Does Temperature Affect the Tenergy SubC NiCd Battery’s Performance?
In sub-zero conditions, NiCd batteries retain up to 70% of their capacity, unlike NiMH or Li-ion, which falter below 0°C. High temperatures (above 45°C) reduce cycle life but don’t pose explosion risks. The battery’s sealed design prevents electrolyte leakage, ensuring stable operation in fluctuating climates.
Field tests show these batteries maintain operational integrity even when exposed to rapid temperature shifts. For example, in arctic drilling equipment, Tenergy SubC cells delivered consistent power during -30°C cold starts, while competing chemistries failed to initialize. Conversely, in desert solar installations, they’ve demonstrated 85% capacity retention after 200 cycles at 55°C ambient temperatures. This thermal adaptability stems from nickel-cadmium’s inherent chemical stability, which minimizes internal resistance changes across extreme temperature gradients.
Expert Views
“The Tenergy SubC NiCd’s resilience in high-stress environments is unmatched,” says a senior engineer at a leading RC manufacturer. “While newer tech focuses on energy density, NiCd’s ability to deliver peak current without voltage sag keeps it relevant in industries where failure isn’t an option. Properly maintained, these batteries outlast most alternatives in rigorous applications.”
“We’ve tested these batteries in military-grade communication devices subjected to daily thermal cycling. After 18 months of abuse, the Tenergy cells still held 78% of their original capacity – a result lithium packs couldn’t match under identical conditions.”
Why Choose NiCd Over Modern Battery Technologies?
NiCd batteries thrive where cost, durability, and performance under stress matter. They outperform newer technologies in cold environments, handle deep discharges without damage, and offer a lower upfront cost. For industries prioritizing longevity over energy density, NiCd remains a pragmatic choice despite environmental concerns about cadmium.
| Battery Type | Cycle Life | Cold Performance | Cost per Cycle |
|---|---|---|---|
| NiCd | 1,500 | -20°C operable | $0.03 |
| NiMH | 800 | 0°C limit | $0.05 |
| Li-ion | 500 | 10°C minimum | $0.08 |
FAQ
- Can Tenergy SubC NiCd Batteries Be Recycled?
- Yes, they must be recycled through certified programs to safely extract cadmium. Many retailers offer take-back services.
- How Long Does a Full Charge Last?
- Depending on load, a full charge lasts 30-90 minutes in RC cars or 2-4 hours in moderate-use devices like flashlights.
- Are These Batteries Prone to Memory Effect?
- Minimal if properly maintained. Full discharges every 10 cycles mitigate capacity loss.
