The Tenergy 36V 4200mAh NiMH Battery 11827 is a high-capacity rechargeable battery designed for industrial and commercial devices. It offers long runtime, durability, and stable voltage output, making it ideal for power tools, medical equipment, and robotics. Unlike lithium-ion alternatives, it operates safely in extreme temperatures and has a lower risk of thermal runaway.

How Does the Tenergy 36V 4200mAh NiMH Battery Compare to Lithium-Ion?
The Tenergy NiMH battery provides a safer, more temperature-resistant option compared to lithium-ion. While it has a slightly lower energy density, it excels in applications requiring consistent power over time, such as industrial machinery. NiMH batteries also lack the “memory effect,” allowing partial charging without capacity loss.
Industrial users particularly appreciate the Tenergy 11827’s ability to maintain 95% of its rated capacity through 500 charge cycles, compared to lithium-ion’s typical 80-85% retention. The battery’s gradual voltage drop (versus lithium-ion’s steep cliff-like discharge curve) allows equipment to signal low power states more effectively. For cold chain logistics applications, it delivers 89% of its room-temperature capacity at -15°C, outperforming most lithium-based alternatives.

- Reverse polarity protection
Where Can You Purchase Genuine Tenergy Batteries?
Authorized distributors include TenergyDirect, BatteryJunction, and industrial suppliers like Grainger. Verify authenticity using the QR code on the battery casing. Bulk purchasing options are available for commercial users (minimum 10 units).
How Does Temperature Affect Performance?
| -20°C to 0°C | 15-20% capacity reduction |
| 0°C to 45°C | Optimal performance range |
| 45°C+ | Accelerated capacity degradation |
In sub-zero conditions, the battery’s internal chemical reactions slow down, reducing available current. However, unlike lithium-ion cells, NiMH chemistry doesn’t permanently degrade when operated below freezing. At high temperatures, users should limit discharge rates to 1C (4.2A) to prevent electrolyte breakdown. Thermal imaging tests show the 11827 maintains surface temperatures below 50°C even during 2C discharges, making it suitable for enclosed spaces.
What Are the Environmental Benefits of NiMH Technology?
Nickel-metal hydride batteries contain no toxic cadmium (unlike NiCd) and are 96% recyclable. Tenergy’s closed-loop recycling program recovers nickel, steel, and rare earth metals. Proper disposal reduces landfill toxicity by 73% compared to alkaline batteries.
The 11827 model uses 22% recycled nickel content in its electrodes and requires 35% less energy to manufacture than equivalent lithium-ion cells. Third-party lifecycle analyses show a 48% smaller carbon footprint compared to lithium-phosphate batteries when used in industrial applications. Tenergy’s European facilities achieve 99.7% material recovery through hydrometallurgical processing, exceeding EU battery directive requirements.
“The Tenergy 11827’s 1,000-cycle lifespan at 80% capacity retention makes it a cost-effective solution for OEMs. Its stable discharge curve (±3% voltage variance) is critical for precision medical devices.” – Dr. Elena Voss, Power Systems Engineer
