The Tenergy Lithium SubC 2200mAh battery is a high-performance rechargeable battery designed for devices requiring sustained power, such as vaping devices, robotics, and industrial equipment. With a 2200mAh capacity, 3.7V output, and stable lithium chemistry, it balances energy density, durability, and safety. Its SubC size ensures compatibility with specialized applications where standard batteries fall short.
How to Prevent Lithium-Ion Battery Fires and Explosions
How Does Temperature Affect Its Performance?
At -20°C, capacity drops to 65% but recovers fully at room temperature. Above 45°C, self-discharge increases by 15% monthly. The battery’s ceramic separator prevents internal short circuits during thermal stress, unlike cheaper polyethylene separators.
In extreme cold environments, users should allow batteries to gradually warm to 10°C before charging to prevent lithium plating. For high-temperature operations, active cooling systems can extend cycle life by 22%. Field tests show the battery maintains 85% capacity after 200 cycles in fluctuating 20°C-50°C environments, outperforming competitors’ 72% retention. Engineers recommend pairing with thermal management sleeves for applications like solar-powered weather stations or desert robotics.
| Temperature Range | Capacity Retention | Recommended Use Case |
|---|---|---|
| -20°C to 0°C | 65-75% | Emergency backup systems |
| 0°C to 45°C | 95-100% | Indoor robotics |
| 45°C to 60°C | 85-90% | Outdoor surveillance |
What Safety Features Does It Include?
The battery integrates a CID (Current Interrupt Device) to halt current during overpressure, a PTC (Positive Temperature Coefficient) thermistor to limit overheating, and a venting system for gas release. Its LiFePO4 chemistry reduces thermal runaway risks compared to standard Li-ion cells.
The multi-stage protection system activates at precise thresholds: CID trips at 1.8MPa internal pressure, while PTC limits current above 75°C. Third-party testing revealed these safeguards prevent catastrophic failure even during nail penetration tests. The venting mechanism releases gases at 150kPa through a laser-etched weak point, maintaining cell integrity. Compared to older models, Tenergy’s design reduces thermal event probability by 40% in high-drain applications.
“The CID/PTC combo in Tenergy’s cells provides redundant protection missing in budget batteries. For mission-critical medical devices, this layered approach is non-negotiable.” – Battery Safety Institute Report 2023
FAQs
- Can I Use This Battery in a Modified Device?
- Only if the device’s voltage range includes 3.7V-4.2V. Modifying devices to bypass protection circuits voids warranties and risks thermal runaway.
- Does It Require a Special Charger?
- Yes. Use a charger supporting Li-ion/LiPo chemistry with CC/CV (Constant Current/Constant Voltage) phases. Avoid NiMH chargers—they’ll overcharge the cell.
- How Do I Check Battery Health?
- Measure internal resistance with a battery analyzer. Values above 25mΩ indicate aging. Capacity can be tested via full discharge/charge cycles using a smart charger.
