Product Overview
The ECOLTO HBC™ (Hybrid Battery-Capacitor) represents a breakthrough in energy storage technology, combining the high energy density of a battery with the high power density and rapid charge-discharge capability of a supercapacitor. Operating across an exceptional temperature range of -40℃ to 70℃ and supporting continuous charge/discharge rates up to 20C/30C, it delivers reliable, high-power performance for demanding applications in automotive, industrial, renewable energy, and backup power systems.

Core Technology & Advantages
By integrating battery and capacitor characteristics, the HBC™ offers a unique blend of long cycle life, high energy retention, and instantaneous power delivery. Its hybrid design reduces the limitations of traditional energy storage devices, providing a versatile solution where both sustained energy and burst power are required.

Exceptional Temperature Resilience
Rated for operation from -40℃ to 70℃, the HBC™ performs reliably in extreme environments—from frigid cold to high heat—making it suitable for outdoor, automotive, and industrial applications where temperature stability is critical.

High Current & Fast Response
With continuous charging up to 20C, discharging up to 30C, and pulse discharge up to 50C, the HBC™ supports high-power applications that require rapid energy transfer, such as engine starting, regenerative braking, power backup, and pulse loads.

Robust Performance Under Stress
The HBC™ maintains strong performance under rigorous conditions, including high-temperature floating (65℃, 1000 hours) and high-humidity storage, with capacitance retention ≥70% and controlled internal resistance increase—ensuring long-term reliability in challenging operational environments.

Wide Range of Standard Models
We offer a comprehensive series of HBC™ products with capacities ranging from 450mAh to 1080mAh (2.5V–3.8V equivalent), multiple form factors, and varied current ratings. This allows precise selection based on voltage, energy, power, and size requirements.
