What Are the Key Specifications of the Tenergy 14.4V 10500mAh Battery?
This battery operates at 14.4 volts with a 10500mAh capacity, delivering 151.2Wh of energy. It uses lithium-ion cells with a low self-discharge rate (<3% per month) and supports fast charging (2–3 hours). Its operating temperature ranges from -20°C to 60°C, and it includes built-in protection against overcharge, over-discharge, and short circuits.
The combination of high capacity and voltage stability makes it particularly suitable for devices requiring consistent power delivery. For example, in medical ventilators, the battery maintains critical operations for 6-8 hours on a single charge. The fast-charging capability reduces downtime by 40% compared to standard Li-ion batteries, while the ultra-low self-discharge ensures readiness even after months of storage. Engineers value the modular design, which allows easy integration into custom battery packs for specialized industrial equipment.

How Does the Tenergy 14.4V Compare to NiMH or Lead-Acid Batteries?
Unlike NiMH or lead-acid, this Li-ion battery offers higher energy density (≈200Wh/kg vs. 50–100Wh/kg), lighter weight, and no memory effect. It outperforms in cycle life (500+ vs. 200–300 cycles) and maintains voltage stability under load, critical for precision devices.
In practical applications, the weight advantage becomes particularly noticeable. A typical lead-acid battery with comparable capacity weighs 4.7kg, while the Tenergy Li-ion version is only 1.1kg. This 76% reduction enables new possibilities in drone design and portable medical devices. The absence of memory effect allows partial charging without capacity degradation – a crucial feature for emergency equipment that requires frequent top-ups. Field tests show 23% better cold-weather performance compared to NiMH alternatives, maintaining 85% capacity at -10°C versus 62% for NiMH batteries.
| Feature | Li-Ion | NiMH | Lead-Acid |
|---|---|---|---|
| Energy Density | 200Wh/kg | 100Wh/kg | 50Wh/kg |
| Cycle Life | 500+ | 300 | 200 |
| Self-Discharge/Month | 3% | 20% | 5% |
