The Tenergy 14.8V 13000mAh Li-ion rechargeable battery delivers high-capacity power for devices requiring sustained runtime, such as drones, medical equipment, and portable power stations. Its lithium-ion chemistry ensures lightweight design, low self-discharge rates, and up to 1,000 charge cycles. Safety features include overcharge protection and thermal controls, making it ideal for industrial and consumer applications demanding reliability.
How to Test Continuity with a Multimeter
How Does Temperature Affect Performance and Lifespan?
At -20°C, capacity drops to 65% but recovers at ≥0°C. Prolonged exposure above 45°C accelerates electrolyte breakdown, reducing cycle life by 40%. Optimal use between 10°C-35°C preserves 80% capacity after 800 cycles. Avoid charging below 0°C—plating risks cause internal shorts.
Temperature management is critical for maximizing this battery’s potential. In cold environments, users should insulate battery compartments or employ mild heating systems to maintain performance. Conversely, high-temperature applications require active cooling solutions like heat sinks or forced airflow. The built-in thermal sensors trigger automatic shutdown at 70°C, but consistent operation above 50°C degrades anode materials 3x faster than recommended levels. For seasonal storage, maintain batteries at 15°C-25°C with 40-60% charge to minimize aging effects.

What Safety Certifications Does This Battery Hold?
The battery complies with UL 2054, UN38.3, and IEC 62133 standards. Its PCM includes multi-layered protections: overcurrent (≥15A cutoff), cell balancing (±25mV accuracy), and redundant thermal fuses. These certifications ensure air transport compliance and mitigate risks in sensitive environments like hospitals.
UL 2054 certification specifically validates fire and electrical safety under fault conditions, requiring 10 consecutive charge-discharge cycles without combustion. The UN38.3 air transport certification mandates rigorous altitude simulation, thermal testing, and impact resistance checks. For medical applications, the IEC 62133 certification guarantees electromagnetic compatibility with life-support devices. Third-party testing data shows this battery withstands 150% overcharge voltage for 15 minutes without venting – exceeding industry norms by 22%.
“The Tenergy 14.8V pack bridges a critical gap in mid-range power systems. Its 3P cell grouping reduces internal resistance, which is vital for UAVs needing sudden current spikes. However, users must prioritize balanced charging—imbalanced cells account for 70% of premature failures we see in the field.” — Senior Engineer, Power Systems Solutions
FAQs
- How long does it take to charge fully?
- With a 2A charger: ~7 hours. A 4A charger reduces this to 3.5 hours, but exceeding 1C (13A) charging risks PCM tripping.
- Is it compatible with DeWalt/Makita tools?
- No—most power tools use 18V/20V systems. A voltage booster (14.8V→18V) can enable compatibility but voids warranties.
- What’s the warranty period?
- 12 months, covering manufacturing defects. Capacity dropping below 60% within 300 cycles qualifies for replacement.
