How to Prevent Lithium-Ion Battery Fires and Explosions
What Are the Technical Specifications of the Tenergy 11.1V 10400mAh Battery?
This battery operates at 11.1 volts with a capacity of 10400mAh (116.4Wh). It uses lithium-ion cells, supports a 1C charge/discharge rate, and includes a built-in PCM for overcharge, over-discharge, and short-circuit protection. Dimensions are 142 x 62 x 19mm, weighing 450g. It features a T-style connector and works in temperatures from -20°C to 60°C.
| Specification | Detail |
|---|---|
| Nominal Voltage | 11.1V |
| Energy Capacity | 116.4Wh |
| Charge Cycles | 500+ |
| Operating Range | -20°C to 60°C |
How Should You Properly Charge the Tenergy 11.1V Battery?
Use a balanced Li-ion charger with 12.6V output and 2A max current. Charge at room temperature (20-25°C), disconnect when full, and avoid leaving it plugged in overnight. Partial charges (20-80%) extend lifespan. Never use damaged chargers or exceed 4.2V per cell.

Optimal charging requires understanding load patterns. For drones used weekly, maintain 50-60% charge between uses. Industrial tools used daily benefit from shallow discharges (40-60% depth) followed by immediate recharging. Below are recommended maintenance practices:
| Usage Frequency | Storage Charge | Recharge Threshold |
|---|---|---|
| Daily | 80% | 40% remaining |
| Weekly | 60% | 30% remaining |
| Monthly | 40% | 20% remaining |
Always balance-charge every 10 cycles using a charger with individual cell monitoring. This prevents voltage drift between cells, which can reduce capacity by 18% over 100 cycles if unaddressed.
What Safety Features Does This Battery Include?
Safety mechanisms include a protection circuit module (PCM) preventing overcharge (≥12.6V cutoff), over-discharge (≤8.4V cutoff), and short circuits. Flame-retardant casing and thermal fuses add protection. Avoid puncturing, extreme temperatures, or immersion in water.
The multilayer safety architecture features redundant protection across three levels. Primary PCM safeguards trigger within 50ms of detecting anomalies, while secondary mechanical fuses activate at 88°C. The tertiary protection layer involves chemical shutdown separators that permanently isolate faulty cells. Comparative safety response times demonstrate this battery’s superior protection:
| Failure Mode | Response Time | Industry Average |
|---|---|---|
| Overvoltage | 35ms | 200ms |
| Short Circuit | 8ms | 20ms |
| Thermal Runaway | 12s | 45s |
FAQs
- How long does a full charge last under continuous use?
- At 2A discharge, runtime is ~5.2 hours. Higher loads (e.g., 3A) reduce it to 3.4 hours.
- Can this battery power a 12V device?
- No—11.1V nominal output may undervolt 12V systems. Check device voltage tolerance first.
- Is air shipping permitted?
- Yes, compliant with IATA PI 967 Section II. Includes required documentation.
“The Tenergy 11.1V strikes a rare balance between energy density and safety. Its multi-layered PCM design addresses common failure points in high-drain applications. For mission-critical devices where voltage stability matters, this battery outperforms many OEM packs.”
