How Does the Tenergy 8.4V 2000mAh NiMH Battery Compare to Li-ion Alternatives?
Unlike Li-ion batteries, the Tenergy 11307 uses nickel-metal hydride chemistry, eliminating fire risks and offering safer operation. While Li-ion batteries have higher energy density, this NiMH battery provides better thermal stability, lower cost per cycle, and no “memory effect,” making it ideal for devices like cordless drills or RC cars that require frequent partial recharging.
What Devices Are Compatible with the Tenergy 11307 Battery?
This battery powers 7.2V–9V devices, including RC vehicles, medical equipment like portable oxygen concentrators, professional photography flashes, and cordless tools. Its flat discharge curve ensures consistent performance in high-drain applications. Always check voltage requirements and physical dimensions (98mm x 33mm x 22mm) before use.

Why Choose NiMH Over Other Battery Chemistries for Specific Applications?
NiMH batteries like the Tenergy 11307 excel in scenarios demanding safety, wide temperature tolerance (-20°C to 60°C), and moderate energy needs. They outperform lead-acid in weight-sensitive applications and alkaline in reusable contexts. For example, in emergency lighting systems, their low self-discharge (15% monthly) ensures readiness without frequent recharging.
How to Properly Charge and Maintain the Tenergy 11307 Battery?
Use a smart NiMH charger with 0.5C–1C current (1A–2A). Charge at 1.4V/cell cutoff voltage. Avoid overcharging beyond 16 hours. For storage, keep at 40% charge in 10°C–25°C environments. Monthly conditioning cycles (full discharge/recharge) maintain capacity. Clean contacts quarterly with isopropyl alcohol to prevent voltage drops.
How Does Temperature Affect the Tenergy 11307’s Performance?
At -20°C, capacity drops to 65% but recovers when warmed. Above 45°C, internal resistance increases by 30%, reducing runtime. Store in shaded, dry areas. For cold environments, insulate the battery compartment. Avoid direct sunlight exposure during operation to prevent accelerated aging.
The battery’s optimal performance window between 15°C and 35°C makes it suitable for most indoor applications. Engineers have implemented a thermal stabilization layer in the cell structure that minimizes electrolyte freezing in sub-zero conditions. For high-temperature scenarios, the built-in thermal fuse interrupts current flow if internal temperatures exceed 85°C. Users operating in extreme environments should consider these performance characteristics:
| Temperature | Capacity Retention | Cycle Life Impact |
|---|---|---|
| -20°C | 65% | +15% wear per cycle |
| 25°C | 100% | Standard |
| 45°C | 85% | +30% wear per cycle |
What Safety Certifications Does This Battery Hold?
The Tenergy 11307 meets UL 2054, IEC 61951-2, and RoHS standards. It’s mercury/cadmium-free and includes overcharge protection circuits. The ABS+PC casing withstands 50J impacts, and the pressure relief vent activates at 300kPa to prevent rupture.
Third-party testing confirms compliance with UN38.3 transportation safety requirements, making it certified for air shipping. The flame-retardant housing material (94V-0 rating) prevents combustion propagation. Each production batch undergoes six safety checks including short-circuit simulation and crush testing. These certifications ensure compatibility with medical and aerospace applications where failure prevention is critical. Key certification benchmarks include:
| Standard | Test Requirement | 11307 Performance |
|---|---|---|
| UL 2054 | Overcharge at 2C for 24h | No leakage/explosion |
| IEC 61951-2 | 500 cycles at 1C | ≥80% capacity retention |
| RoHS | Heavy metal content | 0ppm Cd/Pb/Hg |
“The Tenergy 11307’s hybrid cathode design bridges the gap between traditional NiMH and modern LiFePO4 batteries. Its 2000mAh capacity at 8.4V delivers 16.8Wh energy—optimal for mid-power devices needing 1–3 hours of continuous use. The proprietary separator material reduces internal resistance by 18% compared to industry averages, enabling faster recharge without compromising cycle life.” — Battery Technology Analyst
FAQ
- How long does the Tenergy 11307 last per charge?
- Runtime depends on device draw: 2000mAh provides 2 hours at 1A load, 1 hour at 2A. For RC cars averaging 15A bursts, expect 8–12 minutes continuous use.
- Can I use this battery in series/parallel configurations?
- Series connections increase voltage (e.g., two batteries = 16.8V). Parallel setups boost capacity (e.g., two batteries = 4000mAh). Ensure matched charge levels and cycle counts to prevent imbalance.
- Is the Tenergy 11307 airport-safe?
- Yes—its energy content (16.8Wh) is below the 100Wh limit for carry-on air travel. Always carry original packaging showing specifications during security checks.
