The Tenergy 3800mAh NiMH Rechargeable Battery stands out for its high capacity, eco-friendly design, and versatility. With 3800mAh, it powers high-drain devices like digital cameras and RC toys efficiently. Unlike disposable batteries, it’s rechargeable up to 1,000 cycles, reducing waste. Its stable voltage and low self-discharge rate make it ideal for intermittent use.
How to Prevent Lithium-Ion Battery Fires and Explosions
How Does the Tenergy 3800mAh NiMH Battery Compare to Lithium-Ion?
While lithium-ion batteries offer higher energy density, the Tenergy 3800mAh NiMH excels in safety, cost-effectiveness, and compatibility with standard chargers. It operates reliably in extreme temperatures and avoids risks of thermal runaway, making it safer for household devices. However, lithium-ion remains lighter and better for compact tech like smartphones.
| Feature | Tenergy NiMH | Lithium-Ion |
|---|---|---|
| Energy Density | 80-100 Wh/kg | 150-200 Wh/kg |
| Safety | No thermal runaway | Requires protection circuits |
| Cost per Cycle | $0.03 | $0.10 |
For users prioritizing affordability and safety over compact size, the Tenergy NiMH is a superior choice. Its ability to withstand frequent charging cycles without performance degradation makes it ideal for power tools and emergency backup systems. Additionally, NiMH batteries don’t require complex battery management systems, simplifying integration into existing devices.

What Environmental Benefits Does This Battery Offer?
The Tenergy 3800mAh NiMH reduces landfill waste by replacing hundreds of disposable batteries. Its nickel-metal hydride chemistry is less toxic than cadmium-based NiCd batteries. Recycling programs for NiMH are widely available, further minimizing ecological harm.
Manufacturing NiMH batteries consumes 33% less energy than producing alkaline equivalents. Over a 5-year period, a single Tenergy cell can prevent 48 lbs of CO2 emissions compared to disposables. Many recycling centers recover 95% of the battery’s nickel content for reuse in stainless steel production, creating a closed-loop system. Consumers can further reduce their footprint by pairing these batteries with solar chargers.
“The Tenergy 3800mAh NiMH bridges affordability and performance for hobbyists and professionals. Its high cycle life and low self-discharge make it a sustainable choice, especially in renewable energy systems. However, users must pair it with quality chargers to unlock its full potential.” — Industry Expert, Power Solutions Sector
FAQ
- How Long Does It Take to Charge the Tenergy 3800mAh?
- With a 1,000mA charger, it takes ~4 hours. Fast chargers (2,000mA) cut time to 2 hours, but may reduce lifespan.
- Is This Battery Compatible with All NiMH Chargers?
- Yes, but use chargers with overcharge protection. Avoid “dumb” chargers that lack voltage monitoring.
- Does the Tenergy 3800mAh Work in AA Devices?
- No—it’s a sub-C size battery. Use adapters for devices requiring AA/AAA sizes.
