What Are the Key Specifications of the Tenergy NiMH 7.2V 3000mAh Battery Pack?
This battery pack operates at 7.2 volts with a 3000mAh capacity, providing extended runtime for devices. It uses nickel-metal hydride (NiMH) chemistry, which offers a 1.2V nominal voltage per cell. The pack includes six cells in series, supports 2-3 hour charging times with a compatible charger, and weighs approximately 200 grams, ensuring portability without sacrificing power.
| Feature | Detail |
|---|---|
| Voltage | 7.2V (6 cells) |
| Capacity | 3000mAh |
| Chemistry | Nickel-Metal Hydride |
| Charging Time | 2-3 hours |
The pack’s six-cell configuration ensures stable voltage delivery even under heavy loads, making it suitable for RC vehicles pulling 15-20A continuously. Its flat discharge curve maintains 90% capacity until the final 10% of charge, unlike LiPo batteries that drop rapidly. Engineers appreciate the 0.025V/cell self-discharge rate, which allows storage for months without significant power loss.

What Safety Features Does the Tenergy NiMH 7.2V Battery Offer?
The pack includes overcharge protection, short-circuit prevention, and a robust PVC shrink wrap to resist leaks. Built-in thermal sensors in some chargers prevent overheating. For optimal safety, avoid puncturing cells, store at room temperature, and use a charger with automatic cutoff (e.g., Tenergy TB6B).
Advanced safety mechanisms include pressure relief vents that activate if internal temperature exceeds 70°C, safely releasing gas without explosion risks. The cells feature flame-retardant separators between electrodes, a critical design absent in older NiCd models. Users should still follow basic protocols: never charge damaged batteries, keep terminals clean, and avoid stacking multiple packs during charging. These features collectively reduce failure rates to less than 0.1% in controlled tests.
“The Tenergy NiMH 7.2V 3000mAh pack strikes a rare balance between affordability and performance. Its low self-discharge rate (15% per month) makes it reliable for intermittent use, while the high cycle life ensures long-term value. For users prioritizing safety and simplicity over ultra-high energy density, this is a top-tier choice.” — RC Power Systems Analyst
FAQs
- How Long Does the Tenergy 7.2V 3000mAh Battery Last Per Charge?
- Runtime depends on device power draw. A 3000mAh pack powers a 10W RC car for ~30 minutes. Lower-drain devices like LED lights may last 5–8 hours.
- Is This Battery Suitable for Air Travel?
- Yes. Unlike LiPo, NiMH batteries aren’t restricted as hazardous materials. Carry-on only; check airline policies for capacity limits (usually ≤100Wh).
- Can I Use a LiPo Charger for This NiMH Pack?
- No. LiPo chargers use different voltage curves. Use only NiMH-compatible chargers to prevent damage. Tenergy’s TN140U is a recommended option.
