Are There Safety Risks Associated with the Tenergy 31199 Battery?
The Tenergy 31199 includes multiple safety features: short-circuit prevention, over-discharge protection, and temperature control. Risks arise only with improper handling—avoid puncturing, exposing to fire, or using damaged chargers. Store at 50% charge in cool, dry environments to maximize lifespan.
While the battery’s protection circuits mitigate most risks, users should avoid stacking multiple batteries without protective cases. Thermal runaway can occur if cells are physically damaged or exposed to temperatures above 70°C. A 2023 industry study showed lithium-ion batteries with multilayer PCB protection (like the 31199) have 83% lower failure rates compared to basic protected models. For optimal safety, pair with Tenergy’s TC-100 charger that features automatic voltage detection and charge termination.
How Long Does the Tenergy 31199 Battery Last on a Single Charge?
Runtime depends on device power draw. For a 50W RC car, it provides ≈1.1 hours of continuous use. Low-power devices like LED lights can run for 15+ hours. The battery’s low self-discharge rate (3% monthly) ensures retained charge during storage.
Can the Tenergy 31199 Be Used in Extreme Temperatures?
Operational range is -10°C to 60°C. Below freezing, capacity drops by 20-30%; above 45°C, internal resistance increases, reducing efficiency. Avoid charging outside 0°C-40°C to prevent damage.
| Temperature Range | Capacity Retention | Recommended Action |
|---|---|---|
| -10°C to 0°C | 70-80% | Pre-warm before use |
| 20°C to 40°C | 100% | Ideal operating range |
| 45°C to 60°C | 85-90% | Limit discharge cycles |
What Certifications Does the Tenergy 31199 Battery Hold?
Certifications include UL 2054, UN38.3 for air transport, and RoHS compliance. These ensure adherence to safety, environmental, and transportation standards.
