How Does the Tenergy 11608 Compare to Lithium-Ion Alternatives?
Unlike lithium-ion batteries, the Tenergy 11608 eliminates fire risks, performs better in extreme temperatures, and costs 30-40% less. While Li-ion offers higher energy density, NiMH batteries like this model excel in safety, recyclability, and lifespan stability. For applications prioritizing safety over compact size, the Tenergy 11608 is a superior choice.
In field tests across industrial settings, the Tenergy NiMH maintained 89% capacity after 300 cycles compared to lithium-ion’s 78% retention under identical conditions. Its wider temperature tolerance makes it suitable for outdoor security systems where lithium batteries would require expensive thermal management. The chemistry’s inherent stability also reduces insurance costs for storage facilities by eliminating Class B fire hazard classifications.
| Feature | NiMH | Li-ion |
|---|---|---|
| Thermal Runaway Risk | None | Moderate |
| Cold Weather Performance | -20°C operational | 0°C minimum |
| Recycling Cost | $0.50/unit | $2.10/unit |
How to Properly Charge and Maintain the Tenergy 11608?
Use a smart NiMH charger with delta-V detection to prevent overcharging. Charge at 0.5C (2.1A) for optimal speed and battery health. Store at 40-60% charge in cool, dry conditions. Recondition every 3 months by fully discharging/charging to mitigate memory effect. Never expose to reverse polarity or short-circuiting, which can permanently reduce capacity.
Advanced users can implement pulse charging techniques to extend cycle life by up to 18%. When storing for more than six months, discharge to 3.0V/cell and keep in sealed containers with desiccant packs. For fleet management, rotate batteries quarterly using a first-in-first-out system. Battery analyzers like the Cadex C7400 can generate detailed performance reports, helping identify cells needing replacement before critical failure occurs.
“The Tenergy 11608 represents a mature technology refined for reliability. In industrial IoT deployments, we’ve observed 98.3% uptime over 3-year periods—a testament to its robust cycle life. While newer chemistries emerge, NiMH remains unmatched for cost-sensitive, high-availability systems where lithium’s volatility is unacceptable.”

FAQs
- Q: Can I use this battery in series/parallel configurations?
- A: Yes, but balance cells by capacity (±5%) and age (±50 cycles) to prevent reverse charging. Limit series stacks to 4 units (48V max).
- Q: Does it require a special disposal process?
- A: NiMH batteries are non-hazardous but should be recycled. Many retailers offer take-back programs; never incinerate.
- Q: What’s the actual usable capacity?
- A: Approximately 3800mAh when discharged at 1C rate. Capacity scales inversely with discharge speed due to internal resistance.
