The Tenergy NiMH 12V 3800mAh Battery 11660 is a high-capacity, rechargeable power source designed for devices requiring sustained energy output. Its nickel-metal hydride (NiMH) chemistry offers eco-friendliness, minimal memory effect, and reliable performance in high-drain applications like RC vehicles, medical devices, and industrial equipment. With 3800mAh capacity, it balances longevity and compactness, making it ideal for power-hungry gadgets.
How to Prevent Lithium-Ion Battery Fires and Explosions
How Does the Tenergy NiMH 12V 3800mAh Battery Compare to Other Rechargeable Batteries?
Unlike lithium-ion batteries, the Tenergy NiMH 12V 3800mAh Battery operates safely under high temperatures and avoids thermal runaway risks. It outperforms standard NiMH batteries with higher energy density (3800mAh) and a 12V output, making it suitable for heavy-duty applications. Unlike lead-acid batteries, it’s lighter, maintenance-free, and environmentally safer due to the absence of toxic metals.
For users needing a middle ground between cost and performance, this battery fills a critical niche. While lithium-ion variants excel in energy density, they require precise charging systems and thermal controls. The Tenergy NiMH model simplifies deployment in environments where temperature fluctuations are common, such as outdoor solar installations or automotive backup systems. Its 1-2 hour fast-charging capability also reduces downtime compared to traditional NiMH batteries that often need 4-6 hours for full replenishment.
| Battery Type | Energy Density | Charge Cycles | Safety Rating |
|---|---|---|---|
| Tenergy NiMH | 100 Wh/kg | 500+ | High |
| Standard Li-ion | 250 Wh/kg | 300-500 | Medium |
Why Choose NiMH Over Lithium-Ion for Specific Applications?
NiMH batteries like the Tenergy 11660 are preferable in high-temperature environments, cost-sensitive projects, and applications requiring safer chemistry. They don’t require complex battery management systems (BMS), reducing overall system costs. Additionally, NiMH batteries are easier to recycle and pose fewer fire risks compared to lithium-ion.
In medical device applications, the stability of NiMH chemistry becomes paramount. Defibrillators and portable diagnostic equipment benefit from the battery’s ability to maintain consistent voltage output during critical operations. Industrial users appreciate the lack of mandatory disposal protocols required for lithium batteries in many jurisdictions. For hobbyists, the ability to store these batteries at partial charge without capacity degradation makes them ideal for seasonal equipment like RC boats or holiday lighting systems.
“The Tenergy 11660’s thermal resilience makes it indispensable for our desert-based wildlife cameras. Lithium packs would fail within weeks under 50°C heat, but these NiMH units last entire seasons.” – Sarah Lin, Field Researcher
FAQ
- How Long Does the Tenergy NiMH 12V 3800mAh Battery Last Per Charge?
- Runtime depends on device power draw. A 10A device would last ~22 minutes (3800mAh ÷ 10,000mA = 0.38 hours). Lower-drain devices like LED lights (1A) can run for 3.8 hours.
- Can This Battery Be Used in Series or Parallel Configurations?
- Yes, but ensure all batteries in the pack have identical age, capacity, and charge levels. Series connections increase voltage (e.g., 24V with two batteries), while parallel setups boost capacity (7600mAh). Use a balancing charger to prevent uneven charging.
| Configuration | Voltage | Capacity | Use Case |
|---|---|---|---|
| Single Unit | 12V | 3800mAh | RC Vehicles |
| 2S (Series) | 24V | 3800mAh | Power Tools |
Where to Buy Authentic Tenergy NiMH 12V 3800mAh Batteries and Avoid Counterfeits?
Purchase directly from Tenergy’s website, Amazon’s official store, or authorized retailers like Battery Junction. Counterfeits often lack the laser-etched serial number, have inconsistent weight (±10g), and poor packaging quality. Verify authenticity using Tenergy’s online verification tool. Bulk buyers should request ISO 9001 certification from suppliers to ensure quality compliance.
